Buttons are great. That's why I have a dedicated hardware mixer (1604vlzpro)and all outboard digital effects in my studio. Only the MTR is digital(vsr880) - all the rest is "hand on".
I like the feel on instant gratification when I turn something ... I wanna HEAR a change !
So..... you like thge Nord, huh? Is it Moog-ish? Fat, stacked oscilators and all?
Every instrument, every voice, every sound in nature ... these are are all my private tutors ... 24/7 for free, and all I have to do is listen.
