I use groups like individual tracks with each group having only one sound/instrument per group - instead of having multiple sounds on a single group. Besides setting up Mastar Macros, is there an easier/better/faster way to control the sound/instrument in group one (for ex. filter, resonance, filter env, etc.) while playing (improvising a melody for example) on another sound/instrument in group two? Or is setting up a bunch of macros in Master the only way to do this? Thanks.
