I am thinking of building up an hour-long performance using song mode in A4 MK2. This would make me focus on other things rather than remember when to change patterns or mute things. However, before I reach the brickwall, is there any limit of ROWs and chains in song mode that can be used for each project? I cannot find this info in manual. Does this limit (if any) applies to OT/Rytm as well?
