I am new to beat step so this might be a simple fix. Spark plays on all 3 sequencers even with midi chanels set on seq 1 to 1, seq 2 to 2 and drums to 10. How can I keep spark on the drum sequencer and assign another VST to the other sequencers? When I open another VST like Kork M1 for example, it says failed to open midi device (probably because it is connected to Spark). Would appreciate any help, thanks
