I'm going bloody mad

File problems Renoise 2.8.

I have a song file that is just comprised of 6 hardware synths being triggered by midi commands in their respective separate tracks.

It’s crashed a few times. But now I can’t get Renoise to recognise a new hardware synth or even a VST synth. If I start a NEW song file. The new hardware synth and VST synths work just fine.

So something in the song file is corrupted for new instruments. I’ve tried deleting unused patterns, instruments all to no avail. None of the midi settings are any different in the bad track or a new song track if I create one.

I don’t want to abandon the track. I am going mad. Please help.

Does it open without problems in (the demo of) Renoise 3.1?

What does the log file say about the crashes? (find the log file through renoise ‘Help/Show the log file…’ top left portion of the gui).
