Hi – just like to report this issue with C8.0.20.
I use a synth that uses bank changes via CC0 rather than the default CC32, so I use a Quick Control entry to set the bank.
Unfortunately Cubase doesn’t save the state of this control – it resets to 0 when you load the project, so I have to manually set it back to the bank I want, then nudge the patch up and down to get it sent to my synth.
Reproduce by putting a CC0 with value 1 in a Quick Control line, save, close, restart and note it’s now set to 0.
