Edit instruments? GBX
Can the VIs be edited in any way - say I wanted a copy that's 1 octave lower than the original piano without having to go in and transpose every track.
Can filters, effects, envelopes be added to alter the built in instruments and saved as new patches? Probably NO in GB - how about in Logic Pro X?
