You are most welcome for the reply and I am sorry the news couldn't have been better.
Yes, as of firmware 1.29, some soft midi thru capabilities were offered, but that was pitchbend, modulation and sustain pedal information, through the 4 sequencer tracks and nothing beyond. Yes, you read correctly, up before firmware 1.29, ZERO midi information could be passed through, besides note on/off and velocity. Currently, even as of the latest firmware, all midi cc and program change messages, cannot be passed through the unit, as well as channels outside of the sequencer tracks. I am still hoping this will be remedied at some point.
A midi thru box is invaluable at this point. I'm currently using the midi out of my interface, patched into an oldskool Digital Music Corp MX-8, to get all my midi routing needs and only use the KSP for tracks I want to sequence on, otherwise, it isn't used for anything else. I have to treat it more like 4 sequencers, instead of an actual midi controller.
