Well, I wasn’t confident you would make your way thru it but I was confident that it wasn’t a Gig Performer problem
There’s no magic here — notes (or anything else for that matter) don’t simply work and then suddenly don’t work unless something changed and assigning notes to widgets by mistake is usually the reason notes stop working.
For what it’s worth, the other main reasons notes stop working are
- as @pianopaul suggested, keys are disabled by a plugin for demo purposes
- Some keys are being used as keyswitches (e.g., bottom octave of many hammond plugins are used for changing presets), many Kontakt instruments also use some keys for control purposes
- Samples are missing
As soon as you mentioned widgets, we all guessed the most likely reason - it’s not the first time people have reported on these forums that notes stopped working - that’s why the very first thing everyone asked you to check was your MIDI assignments, a feature we added a long time ago specifically to help with situations like this.
Glad you figured it out.
