I’m in the same boat. No +Drive for my MD at this moment.
Sample management can be tracked here:
With OS1.71, MC can send wav files from the SD card to MD, and will properly handle loop points.
Saving samples to SD is planned.
keep the edited track if one saves a sample recorded with the MD
Not sure if I understand. You mean, when you use the sample manager to copy RAM slot to ROM, it removes something (emm, sequencer data?) ?
