@mbang If it happens again, try opening up the synth and look for any PCB plates that may have become loose and push them (gently) back down again.
I had the exact same issue as you and this just fixed my instrument not ten minutes ago.

@AndyHornBlower Thanks for inspiring me to open it up and having a looksie!
I found a loose PCB (the one with T and P label on it) that I had to push down back onto its pins again and now it starts up perfectly.

@ToFF I'm having the same issue as you. Frozen at startup with "Loading bank" displayed. Did you ever find a way to fix it?

Also I'm running the latest firmware and everything. Everything's been working fine up to this point for 1½+ years.

I think the issue might be with the power supply cable, it keeps loosing power and rebooting when just I barely wiggle the power cord. Not the most reliable when playing live.

@laurent_aodyo Well..expression? X, Y and Z could be mapped to a wide variety of options besides the usual mod, breath etc. Waveshaping, ring modulation.. you name it.

Just downloaded and tested these out. Will definitely be using cosmic noodle 01 extensively! Really expressive and mysterious-sounding stuff. Got any more cool patches to share? :)
