The Arturia Keystep 37 can play software synths stacked on different tracks in Reaper - midi ch 2 - Can sequence an external analog hardware synth - via midi ch 1 - perfectly fine.
Pblm - Not able to sequence software synths in Reaper. What do I need to do? Thank you.
Internal sync - tabs down. Tried switching USB ports. Closing / opening Reaper. Turning on / off AKS37. Removing / installing USB cable into AKS37/
