I just put MH v1.04 on the download page. To be completely honest, I’m not sure what’s been changed since the last version. Velocity support is still limited to only 3 or 4 drum sets.
The reason I’m uploading this is because I only have 9 days left on my student license for Max/MSP, and a permanent license costs $250. Unfortunately, I can’t afford this right now, which means I won’t be able to work on MIDItar Hero for a while.
