Well, that was definitely part of my problem! I had it set to “Toggle between Active and Bypass”, but I had manually assigned Bypass to MIDI CC 0 and Active to MIDI CC 127 misunderstanding them for CC values. Once I set BOTH Active and Passive to MIDI CC 0, I got the MIDI switch on the TMP to work. But there is one additional thing: For this to work as expected, at least with the TMP, I had to set the initial patch active/bypass setting to bypass. That allowed me to do an initial program change when calling up the TMP preset from another TMP preset. The PC simply set the correct effect, cancelling any previous H9 patch. Then, once in the current TMP preset, the MIDI switch I set up in the TMP worked as expected. When setting up a MIDI footswitch in the TMP, you can set both an active and inactive CC message, so the active value sent MIDI CC 0 with a value of 127 to set the H9 patch to active, and the inactive CC message sent MIDI CC0 with a value of 0. And it appears to all work now. Any additional follow up input appreciated.
