I'm trying to think of a hardware keyboard that has several separate insert effects for EVERY Part...
Nope, can't think of ONE...
If you imagine that there can be upwards of eight Parts JUST for the keyboard Parts, then upwards of eight Parts for the Style section, then maybe sixteen more Parts addressable by MIDI, that's 32 Parts, So, say one insert effect on each Part, that's 32 INDEPENDENT effects units... Make that two per Part, 64!
There isn't a hardware keyboard in the world with those numbers!
I guess it's just one more example of how good open keyboards can be at everything. Except, apparently, MAKING MUSIC!
