Program change (MSB and LSB) in either LK or AUM?

Can either LK or AUM get me sending program changes? I can’t seem to figure it out!

    You can add automation lanes in each clip for PC, Bank Select MSB (CC #0) and Bank Select LSB (CC #32) in LK.

    There are 2 types of messages involved in your answer.

    1. Bank Select

    The Bank Select messages are actually MIDI Controller messages, just like Volume, Pan, Sustain Pedal, Wind, and other controllers. Specifically, the controller number for the "Most Significant Byte" (ie, MSB) of Bank Select is controller 0. The controller number for "Least Significant Byte" (ie, LSB) of Bank Select is controller 32. The data for these messages are the bank number you want to select. (Sometimes the MSB Bank Select is referred to as the coarse adjustment for bank, and the LSB Bank Select is referred to as the fine adjustment).

    1. Program Change (which would need to follow a Bank Select) and choose among the 127 (7 bits) choices.

    I'm aware that Xequence can send these messages... since @SevenSystems added this feature way back when I was playing with MIDI messages to call up iSymphonic instruments which shows the MSB/LSB values to dial in the Bank. I never figured out how to make it all work. I think because I assumed Bank Select would dial in the right instrument but I gave up and assumed the feature was broken.

    I hope someone got further than I did and knows if there's a handy AUv3 MIDI app that can send these. Perhaps StreamByter or Mozaic scripts can be created to do this. I'll look around.

    @Wim provided some great clues here:

    @MikeP provides some essential details for the right 2 CC sends and PC follows:

    A control mapped to CC00 that selects 0-127 (MSB)
    A control mapped to CC32 that selects 0-127 (LSB)
    A control mapped to "PC" that sends 0-127 (PC)

    Two years ago, I made a Mozaic-preset for sending PC-messages (with Bank-select) from AUM (or other AUv3-hosts) to my Microfreak synth. You can download it here:
