didn't use my PreenFM mk1 for a long time but started to play around with it lately.
So I loaded Firmware 2.0 and everything does work fine except from one thing.
Currently I do use a Korg ESX to sequence my PreenFM which does work alright,
but when I browse through the patches to preview sound the preen does freeze up
every time I come across an empty slot, while the external sequencer is running.
Same happens with my midi keyboard, the preen does crash as soon as I do trigger
a note while an empty slot is selected.
Any chance this could be a firmware related problem?
