I’m currently experiencing the issue that the SQ Drive controls on the touchscreen in utilities/SQ Drive/Multitrack are working with a recording (transfered from a computer), but the softkeys set to “SQ drive multitrack play/pause/stop” seem to crash the player.
If I already have the track playing, it continues (and even when I shut down the desk, the USB access light still flashes until I switch off the device). However, both sets of controls become unresponsive, and the elapsed/remaining times and progress bar all freeze. Only playback mode stays responsive. If I try to start the multitrack playing with the play/pause softkey, it crashes the player without starting anything.
