It would be handy to have a “solo switch” for the each Oscillator and the Sampler.
I often want to hear Oscillators in solo when building patches. Obviously, I just turn them off, but a “solo” button would be useful.
Not a must have but I think it would be a nice feature.
my sentiments exactly
I personally can see it being done by pressing right mouse button on dot on oscillator you want soloed (so code mutes other oscillators instead - something like reversed action of when you normally press it with left mouse button and it mutes only selected oscillator), I second this!
What do you think about it @Tytel?
Just like it’s in FL currently:
(it’s really comfortable and fast way)
The only problem I see with
is fact that currently it has Learn MIDI Assignment, but other than that it could be absolutely neat and fast workflow and I think people mute/solo oscillator more often than assign MIDI to controls 
Yeah I wouldn’t put a whole new button in but maybe a hotkey for soloing would work. Will have to think about it.
I agree. The hot-key concept is better than my “solo button” suggestion.
