Programmed 16 channels in a chromatic major scale from C, up two octaves to C# on stage 16.
Set the C#'s in mute (stage 2 and 9) and left the channel 16 C# active.
Have a "Kick" generated on stages 1 and 11 with a "snare generated on 5 and 13.
Started in forward mode than, switched to Ping-Pong mode. I have SOS mode enabled (Start on Stage) which provides a double hit on the endpoint stages.
The strings are a bit loud but. The point was that it was in Ping-Pong mode while in C, running up and down the scale.
When I transpose to C#, I kick in the random mode.
When switching back to C, I kick it back to Ping-Pong mode. The sequencer re-enters Ping-Pong at the point and direction that it left when launched into Random mode.
Definitely not a pro production but, gets the control point across.
