Live MIDI recording in sample-based tracker OpenMPT, converted to FTM using a beta of a new converter I'm working on. Notes, note releases, instrument numbers, velocities, note delays. Pretty sweet....
OpenMPT can approximate to the nearest row, so it's not really necessary to add to the converter (which was more intended for human performances anyway). But I have more ideas up my sleeve, like a drumset feature for instant multi-channel drum tracks, multi-row tick conversion for integral tempi, etc.
