Pacemaker mixes are ago go?

The Pacemaker in use

For a long while now I’ve had a problem with my pacemaker… The problem is I can’t reliable use the internal mix recorder. It records like midi by recording the actions and tunes then when you export from the editor it flattens the whole thing into a flatten Ogg Vorbis file.

Problem is it seems to screw up the mixes even though I know the mix was correct. I posted details on the unofficial pacemaker forum but people were blaming Linux, 64bit, Wine or Firmware problem.

Well I’m happy to say since I upgraded the Pacemaker with the new official beta it seems to be better (not perfect). I’m going to give it a proper test soon… If its correct, then it was the firmware all that time, and I should be able to rescue the old mixes, which would be fun. Because the Pacemaker is just a linux device, I’ve also backed it up a few times to my server and then to the cloud.

Expect more travels with pacemaker soon including my airplane mixes…

Pacemaker device upgrade

Pacemaker Device

If you’ve not seen the Pacemaker Device (pmd) had a official firmware update over the last few months. This is great news because this shows pacemaker device isn’t dead, and there might still be a lot more life in this ground breaking device.

The firmware is beta but to be honest it feels very stable to me just like the leak pacemaker firmware from over 3 years ago. One of the major additions is the ability to scratch which I’ve not played with yet, but theres plenty more stuff…

  • Scratching (Vinyl Mode) – Enable it under (Settings, Mix Control, Vinyl Mode). Simply touch the edges of the navigation pad on the Pacemaker to scratch your music.
  • Beat Lock/Sync Mode – Enable beat lock by holding the P-Button down and pressing Play on the second deck. The second deck will be synced to the same tempo as the first and held there until this process is repeated.
  • Sync Tempo – Hold the P-Button down and press Cue on the second deck. The second decks tempo will now match the tempo of the first deck.
  • Beat Jump – Enable beat jump by holding the P-Button down and pressing ‘REW’ on a deck. ‘Beat Jump Enabled’ will be displayed. Repeat this process to jump backward in time in the track or hold the P-Button down and press ‘FWD’ to jump forward in the track. You can change the length of the jump by holding the P-Button down and pressing the ‘REW’ and ‘FWD’ buttons simultaneously. Great for creating a ‘stutter effect’.
  • Fixed Loop Length – Set Fixed Loop Lengths in (Settings, Mix Control, Fixed Loop Length) and all loops you create will default to that length.
  • Snap Loops – Set this on under (Settings, Mix Control, Snap Loops) and all loops that are created will be snapped to the nearest beat.
  • Digital Output (Play mode only) – Requires an A/V cable (Digital out where video should be) and this mode only works on the line-out channel (Hardware limitation)

Its quite easy to upgrade and on Linux, you just need to follow the Mac instructions.

Ensure your Pacemaker has at least 20% charge before starting this process. Download the firmware by clicking here

  1. Connect your Pacemaker Device to your PC via a mini USB cable.
  2. View the Pacemaker drive so you can see the folders on the device (like you would with a memory stick)
  3. Find the .Pacemaker folder (it might be a hidden folder so you might have to enable viewing of hidden folders).
  4. Copy the firmware you downloaded into this folder.
  5. Safely Eject the Pacemaker Device
  6. Your Pacemaker should now reboot and install the firmware – this might take several minutes. Do not unplug your device during this process.
  7. Once completed the device may either need to be ejected again from the computer, or it may display a screen as if it has just been turned on and is ready to mix.
  8. You’re done – Let’s Mix.
  9. Be sure to post your comments over in the official forum thread here, to show your support to the team.

Pacemaker upgrade complete

Here’s my pacemaker with the latest Firmware updated…

Pacemaker playback

Blackberry Playbook

Some of you may have noticed my tweets about finally getting a Blackberry Playbook.

Some of you maybe wondering why the hell I bought one of those?

Well the truth is the original pacemaker guys (Olof Berglof, Jonas Norberg and Willem Demmers) sent me one after my experience of the pacemaker app during Over The Air earlier in summer. Blackberry/RIM suggested they might send me one but after the blog post, they pretty much didn’t want anything else to do with me. Bear in mind, this was after I asked them to send me the playbook to test out before I got to Over the Air.

Thanks from the Pacemaker Team

Anyway after the blog post, I shared it with the un-official pacemaker community which had started when Tonium wouldn’t answer any of the questions. This is where the original pacemaker guys (now free after Tonium) saw it and got in touch with me.

The guys admitted the version I was using was a early beta and it was a lot more stable now. We got talking and they agreed to send me a playbook maybe they felt it was the right thing to do or they wanted to keep me involved in the pacemaker community. Either way I’m happy to say I got one thanks to the Pacemaker guys! And its running the Pacemaker App Trial right now.

Pacemaker App

I won’t talk about my frustration with the actual playbook. Including how the mass storage mode failed to work on Ubuntu and how I had to transfer my music collection over wifi using Samba till I discovered this USB hack. Weird thing is it was just as slow. I won’t talk about the pain of trying to get the latest OS update but it not letting me till the battery was over 20% (I left it over night charging in the end). Finally I won’t talk about the pain of getting a blackberry ID.

The Pacemaker trial is rightly so much more stable than the version I experienced before. Its not crashed on me and it does seem a lot more together. But I have to say I still find some of the latency problems are still there (maybe Android 4.1 Butter is needed but you would have thought QNX would be ideal for this). For example don’t try and do hard cuts with the crossfader as you will be very disappointed. The layout makes a little more sense now but I’m finding lots of things are missing from the pacemaker device including recording, effects and of course external output to a mixer. The later means everything you do is played out over the headphones or split into mono.

Pacemaker App

The Pacemaker guys are going to put me on the beta list so hopefully I’ll get a feel for changes and progression soon enough. Right now, its a much poorer relation to the pacemaker device. There is no way I could play out with this, only have a play now and then when in the mood. Still early days and the pacemaker guys have done some great stuff, but I do wonder if it will get good at the point the platform goes away or dissolves. Of course the Pacemaker guys can’t/won’t talk about beyond the playbook but I’m already thinking of solutions around the dual stereo output problem involving usb sound cards or even 2 devices (phone and tablet anyone?)

I’m greatful to the Pacemaker guys for what they did, its really cool. Because although I was thinking about buying a cheap playbook, after my experience I was dead set against Blackberry and the playbook. Good to know certainly people can take feedback on the chin and move forward…

Out, back and beyond mixes

Its another one of those pacemaker mixes which I’m specially enjoyed doing…

There’s some real classic tunes and plenty of catchy anthems to get you up and dancing or deep into that code if your doing so.

This time it comes into versions, the standard and the extended version. The versions do have slight different bpm and is a little faster and heavier in the extended version, rather than just cut differently.

Pacemaker under glass…!

In my last blog post I wrote how I was given the opportunity to play with an early build of the Pacemaker app on the Blackberry playbook at Over the Air 2012…

I won’t comment on Over the Air 2012 which looked frankly amazing and how great it was to catch up with old London friends even for a few minutes. That was all great and I look forward to catching up with people in the week when I’m down in London.

This is about the playbook and the pacemaker application.

The top line is… almost unusable, shocking and sadly uninspiring!

First of all it took ages to get the files on to the device, for some reason the playbook wouldn’t mount on my ubuntu thinkpad laptop, even though the machine which the guy was using was the exact laptop. Yes even he had a Thinkpad X220 but was running Windows 7 and had installed some magical playbook driver. So we had to copy most of my collection over to his laptop over USB sticks and my Android phone. That problem I blame RIM/Blackberry for… No mass storage mode, even MTP would have been a start. So I assume no Linux support is coming?

Once the files were loaded on to the Playbook, the guy started the Pacemaker application and I was a little underwhelmed to see they had gone with the two decks and a crossfader approach. I was expecting something a little more clever specially with the pacemaker under their belts. The guy whos playbook it was, didn’t know how to use the application and certainly didn’t know how to dj. However there were common interfaces elements with the pacemaker which made it understandable for me. But there were bits like the legendary P switch which was missing. So it wasn’t till half way through that I found out how to change the EQ and Gain. That problem was certainly Tonium’s.

I started with my pacemaker and tried to mix from the pacemaker to the app and it was the most painful mixing I’ve heard in a long while. The problem was the app not only kept skipping and pausing on beats but there was no monitor/headphone out. This for me make the whole thing pointless to use! Not only that, unlike on the pacemaker which showed every beat using an highly efficient system to show you the next 4 beats of both tracks, so you can almost dj without monitoring with some knowledge of the track structure. Tonium opted for the Virtual Dj/Tracktor/etc whole track waveform (forgot to add how long it took to render each wave form, although you can play it blind while it renders). Not very useful when your beats are galloping like some runaway horses. I even tried to use the sync feature but frankly that was rubbish too. The mix was all over the place. Once again Tonium’s fault, as I’m sure the playbook is capable of playing two tracks together at the same time. However RIM/Blackbery need to get 2 discreet outputs otherwise its always going to be a joke (stereo splitters deserve to die, and as I said to the guy. No club is ever going to let you plug in if your splitting the audio! Further rendering it as a bit of fun).

The latency of the touchscreen of the Playbook made the whole thing a total joke. The only time I’ve ever had such bad latency when djing is while trying to mix on a piece of glass during the Thinking Digital conference 3 years ago (by the way the blog about thinking digital is coming soon).

If you don’t understand what I mean by latency go have a look at this great Microsoft research demo where they got the latency of a touchscreen down to 1ms. But it wasn’t just that… As switched back and forth between the Pacemaker and the app, I could feel something was missing. Even with the touchpad of the pacemaker, I could do multiplate it in ways which were just ignored by the playbook. Honestly the interaction rant about pictures under glass was never more apt for this moment. Whos to blame for this? Well both and everyone. Although the trackpad of the pacemaker could be seen as the same as the multitouch screen, its certainly not.

I know a few of you are saying, yeah yeah give it a few weeks and you will also like it But honestly no I won’t. Of course if RIM/Blackberry want to give me one to fully try out over weeks or months then great I won’t say no but I think the end result will be the same. Even if Apple or even Google were to release a Dj app for iOS or Android, I would be saying pretty much the same. The problem isn’t RIM/Blackberry or even Tonium’s, its pictures under glass. You can’t get away from it…

The guy who’s playbook it was, said the later versions he had seen was more stable but frankly if it was bulletproof… Theres far too many other problems…

If I was Tonium, I would scrap the copying Virtual DJ, Tracktor, etc and take advantage of the beat chart system they enabled on the pacemaker. You need to be able to mix without hear the track, because I’m sorry to say the splitter option is a instant no for any self respecting DJ.

Tonium claim they used Blackberrys’s QNX platform because it was quicker and more responsive then others out there. If thats true, then make it so! Right now I’m not seeing anything advantages over the other platform. Even having dual outputs would have put Blackberry well ahead of the game and made the platform much more attractive to djs and artists but right now it looks no different to the rest except there are few apps, few developers and fewer buyers. If RIM/Blackberry really want to do something radical, getting Tonium to build the pacemaker software for them isn’t going to fly unless theres serious hardware changes too.

It hurts me to say it because I really wanted Tonium to go on to a winner and heck if the blackberry platform was the place to do that, then great. But instead what they have done is aped DJ software already out there, added a few bits from Pacemaker and done an very disappointing job.

The thing which is never meant to happen while djing happened! Yes the Pacemaker software crashed and left me scrambling for my pacemaker. Not only that, there was clear machine/software distortion through out when you feel the system was under-stress.

I believe nothing can save this pacemaker app unless its a new blackberry playbook (with low latacy  and 2 outputs)  its going to run on?

The pacemaker is back baby…

Pacemaker meets Playbook

The original pacemaker team did say on a forum of pacemaker fans they were working on a mobile app but I had no idea about this…

Found via Guy West on twitter, Engadget broke the news that the pacemaker was coming back as a RIM blackberry app.

News just in this morning, however, is that the DJ tool is back as a PlayBook app thanks to an exclusive collaboration with the tablet’s maker. Details are sparse right now, as the information spilled at RIM’s event this morning at MWC, but we do know that there will be auto beatmatching, vinyl mode with scratching, digital mode, looping, loop travel, pitch control, beat skip and “pro level” effects. All we have in terms of availability is that it will be out this spring, with no word on price.

On the pacemaker teams facebook page and Pacemaker forum for more details…

Today we proudly announced a partnership with RIM / BlackBerry at a press conference at the Mobile World Congress in Barcelona. As a result, we’re porting the technology of Pacemaker® Device onto the BlackBerry PlayBook.
After investigating a wide range of mobile platforms to make a digital transition we selected the PlayBook due to its highly responsive user interface. DJ’s requires very low latency and the PlayBook delivers very well on that aspect.

For those who don’t own a BlackBerry PlayBook please stay tuned as we have future plans for other platforms as well.

Btw, our next stop will be the South By South West festival in Austin Texas, so if you’re there, let us know 🙂

I’m very tempted to go down to CEX and pick up a 2nd hand Blackberry Playbook but I’m sure Android isn’t far behind…?

There’s a open life in the Pacemaker yet

pacemaker_sonar_june_2007_07

Just when I was starting to wonder if I was going to have to switch back to using a laptop to dj… I receive a email message from the new Pacemaker community

As you probably know we were trying to get hold of the Pacemaker source
code so we could see a future for the Pacemaker.

We have now had contact (has joined our forum) from Jonas who was to
original inventor of the Pacemaker and founded Tonium. He has purchased the
rights to the Pacemaker design & software back, and intends to take this
project forware again!

Not only that he has already offered that the GPL’d source code WILL be
made available on Sourceforge.

We are yet to find out Jonas’ intentions, but this is exciting news for all
us Pacemaker users. Keep checking our forum for any updates.

Jonas posted a message on the forum

Dear PMD users, I invented Pacemaker back in 2005 and founded Tonium later that year. It makes me very happy that PMD is still alive and being used, despite the lack of support and hardship that I know you have gone through. I even recognise some of you from the good old Pacemaker.net days – Sox, Migzy, Regis and many more, you are all remembered.

Developing Pacemaker was among the most exciting things I have ever done. It was a project that came out of a pure passion for music and a feeling that it had to be possible to create a DJ system in the size of an iPod. Developing Pacemaker was also the toughest thing I have ever done. Starting from scratch with nothing but an idea for a hardware device. Luckily, I was very naive and did not foresee the challenges lying ahead.Following the launch and our expansion in the spring of 2008, I was exhausted. We had basically expanded from two people to more than thirty in just a little bit over one year, while developing PMD, PME and Pacemaker.net. Honestly, I was a little bit over my head in managing the kind of company Tonium had become. Therefore I stepped down as the CEO in May 2008. That proved to be a mistake. I was not too impressed with how the company was managed going forwards. But that said, it was not easy for the new management, they were in for a great challenge given the global economy crisis, the smartphone revolution and new disruptive music services popping up. And now, as you all know, Tonium have ceased its operations.

But! I have some news for all of you. On Thursday January 12, it will finally be official that my new company 100 Milligrams have purchased the intellectual property rights for Pacemaker, something I have been trying to do for years. Taking part in this venture is my long time friend Daniel Wallner, co-founder of Tonium and the engineering genius behind Pacemaker®. I am also happy to say that we have added a fresh face and a third member to our core team, Olof Berglof, an innovative designer and marketeer. We have also been able to get a little bit of funding and the three of us are now working day and night to transform Pacemaker into the new music and technology landscape.

We would also like to help supporting PMD users in the best kind of way. Your forum is fantastic and we will point people in your direction as well as trying to be here ourselves as much as possible. When it comes to hardware problems, we will try to be as helpful as we can by providing component information, schematics etc. Unfortunately we cannot promise new firmware versions, at least not for some time. We just do not have the necessary manpower. However, we will in time make sure the auto upgrade from Pacemaker® Editor is working and the GPL source code from Pacemaker Device will be available on SourceForge.

I will personally update you on the progress of the New Pacemaker Project and let me know if you have any questions or ideas.

Cheers,

Jonas (@jonorberg)

How awesome is that!!!
Can’t wait to see what comes next… Open is the way forward, open hardware, open software, open idles…

Goodbye, let’s mix…

I moved away from lets mix years ago even before they did the dirty on the Pacemaker with Pioneer, although its still a shame to see its going…

It is with great regret that Let’s Mix today announces that the Letmix.com mix streaming site will go offline on January 1st 2012. This decision follows the reassessing of our licensing restrictions, alongside a critical evaluation of the business case for our service. Our intention to expand on our operations had fundamentally outgrown the Let’s Mix site.

The closing of Let’s Mix is not the result of complaints from copyright holders. It is a decision based on the equation of cost for hosting and delivering copyrighted components, versus the ability of monetizing use of the site.

We found that as the business of music streaming evolved, so would we need to. Had we desired for Let’s Mix to grow any bigger, we would also have been forced to impose strict limitations on mixes in ways neither we nor our users would have wanted to. Faced with the proposal of sacrifizing user experience and scale, we were forced to reach the difficult decision of seizing all activity at Let’s Mix.

It has been a great pleasure to enjoy the hours upon hours of mixed music, and we are thankful for the many discoveries we have made listening to your mixes.

We have already begun offering our members the ability to download their own music mixes when logged in to their accounts. These are after all your music compilations, and we encourage you to download backups of these unless you don’t already have these in place.

Access to the service in its entity will be terminated on January 1st 2012.

Good to see them providing Data portability of mixes at least… Maybe the ability to transfer to Mixcloud would be good… Although looking at the export ability, it only allows you to download the media file and none of the metadata…. Shame

The Satisfaction Zero mix

Its been a long while since I’ve uploaded a mix to Mixcloud or even Soundcloud. So I decided to throw together a mix on the pacemaker and stick it up. Its a strange mix of some classics and some new tunes. Nothing over thought, just good music mixed together…

Stem based mixing coming your way soon?

Dj Challenge in progress

One of the killer ideas which came out of the Mozilla Festival in the Dj challenge was the idea of Stem based mixing

The idea is great and I think there’s plenty of momentum behind it. Daniel James and Fin Stamp worked this idea through and now there’s a post on the Mixxx forums. Here’s the details of the post…

At the Mozilla Festival in London last weekend, I took part in a Hack the DJ workshop, looking at ways to take digital DJ’ing to the next level. One of the ideas proposed was stem mixing, using multichannel files in DJ applications. A proprietary implementation of this idea is Fireplayer but this app is built with the intention that users will buy remixable versions of (a very limited number of) well-known songs from an in-app store. I would like to work towards a new open standard for stem mixing, something that is compatible with sharing our mixes on the open web – legally, of course – but could also be used by record labels that sell tracks to DJs.

For example, eight channel Ogg Vorbis files where the first two tracks are a stereo mix of the drums, third and fourth stereo bass, fifth and sixth stereo vocals, and seventh and eighth tracks everything else. This means that you can mute or solo individual stems in the mix, giving you the versatility of four-deck or eight-deck mixing but without the problems of keeping many decks in sync, since the stems within a single file are locked on the same timeline. Also, it makes using the mixer a lot simpler than for many-deck mixing, because you don’t need to keep assigning the crossfader to the various different decks.

Of course this means that the eight channel .ogg file has to be prepared specially for DJ’ing, but this is already possible in Audacity. So we have a file format, and an editor, but what we don’t yet have is full support for stem mixing in open source DJ applications. Sweep supports scratching on eight-channel files, but it doesn’t have a mixer. Mixxx has a mixer, but doesn’t support multichannel Ogg files (yet), as far as I can see.

So, what do you think? Is stem mixing a genuinely useful feature that will allow DJs to be more creative, or will it fail if the best music continues to be available in stereo only? Please add your comments below

I like to think this could be massive thing because although you might be able to get the Stem’s of a tune if your a international superstar dj and have contacts in high places. But if your just a bedroom dj or even play out quite a bit but not a popular name, getting access to the stems of a tune is near impossible.

In fact what were trying to do is standardise the format, so it means the bedroom producers and the massive music businesses can compete on a level platform. This might strike fear into some but when the stereo track is no more and everyone is expecting the Stems of the track as standard, then you will have to go along with it.

Ogg Vorbis is a great starting point and knowing it can support up to 200+ tracks is great for future capability. There are a ton of questions of how it works for a Dj but its certainly a challenge which will be fun to have. I just hope we can stay away from the logic/alberton type interface…

Can’t wait to mix with Stem’ed Ogg Vorbis files…!
