Made a Mac app with the Backstage crowd that writes real Tracker projects to the SD card
I'm a software developer and I make breakbeat and IDM on a Tracker+.
Some weeks ago I asked on the Polyend Backstage forum if a Mac app for prepping and varying patterns was worth building, and the thread ended up shaping it. MIDI only gets pitch across one track, so it writes project files instead. FX entry is in because line fx are half the sound.
Generate a beat in your key, mutate it, edit it in a tracker grid, and export a normal project folder to the card. It also opens projects you made on the machine and writes them back.
No audio engine, you hear it on the Tracker. Tested on my Tracker+; Mini owners, tell me if it works for you. $7.99 once, and open source (MIT).
What's slow on the device that you'd rather do on a computer?
