Ha! I still have a couple of CDs laying around of mod collections and sample packs, my tracker of choice was Impulse Tracker (but I played with FT2).

There are still a couple of mod-style trackers floating about (MilkyTracker is probably the most active/popular, and will look very familiar to you as a former FT2 user). Are you familiar with Renoise at all? It’s a modern, cheap DAW, built upon the principles of old-school trackers. I dare say though, it doesn’t have the inherent remixability of MODs that you alluded to in that last sentence.

Myself, I still hobby-track using LSDJ on GameBoys, and related devices/emulators. There’s something appealing about stretching legacy 4-track hardware to its limits.
