Sounds like we're all in the same boat, granted those that want to use all 16 channels "live" have worse problems than in the studio. I still think doing one track at a time in patch mode, still allows you to be creative with the track since it's full sound is there. Then, when previewing the song you switch to performance mode. Finally, when you are ready to record to audio you do so on a track by track basis. After the audio tracks are done, you can go back and mix everything for the master. Personally I can't wait for the next generation synths from Roland and Yahmaha, they will finally get rid of the fx problems once and for all.
