Update 7/28/2020 – fixed mute buttons going to wrong chains
Update 7/24/2020 – fixed hanging notes issue

This router module has 6 separate chains whose outgoing midi can be muted with the first 6 mute buttons of the Korg NanoKontrol. The first 4 module slots are separate chains, and then two sets of 3 for the final two chains. This hasn’t been thoroughly tested, but seems to be working well.
