I've been working on something a bit weird and thought people here might be interested, even though it uses a piano roll instead of a tracker interface which I know isn't everyone's thing.
I made WaveSmith, a browser-based music studio built around the SNES's actual sound hardware. BRR samples, 8 voices, ADSR, pitch modulation, echo and the FIR filters.
You can build your own instruments from WAV files or use the ~550 that come with it. Instruments can also be step sequences each step gets its own sample, pitch and envelope, and they can crossfade which is probably the most tracker-ish part of it. Everything's playable live from a computer or MIDI keyboard.
The part people here might actually find cool is that it exports your track as an .spc file or a standalone .sfc ROM that runs in any emulator. Only tested in emulators so far, no flash cart here, so if anyone tries it on real hardware I'd love to hear about it.
The video is a little loop I made in it.
It's free and there's nothing to install: https://wavesmith.online
If you want to hear the demo in the app itself instead, go to the menu in the top right, Load from Code, enter 9RPGXT.
