more switches! they are so useful for automating transitions between different sections of a composition, or making live adjustments. Since you already have Boss Bow Two for sequential switching, Would consider some simpler bi-directional 1->2 (or 2 -> 1) switches. I just picked up the Instruo Tain and really love it. WMD S3lekt and Acid Rain Switchblade are also popular (although the switchblade isnt bi-directional).

Thanks for this suggestion! I'm going to watch a few videos on the ones you mentioned and the Nonlinearcircuits Chopper.
