KP3 and Program buttons 1-8 extenal MIDI control

I'm trying to control the 8 buttons via MIDI with a sequencer. Basically I have stored in them different programs with other thing set like key, fx etc. I want to be able to call up each of these scenes remotely. Apparently they respond to CC message numbers 49-57. What I did was start my sequencer recording and then press the button on the KP3 I want for that song, and it sent the messages to the sequencer.

The sequencer captured a program change message and 2 CC messages that look like bank select messages, none of which appeared to be 49-57. Playing the sequencer back into the KP3 only changes the basic program number as per the LED readout to its correct number, not actually selects the button (meaning it doesn't light up), and none of the things saved into each button are applied.

What might be going on here? What should my CC numbers string look like, say, when programmed into an editor or sequencer in order for them to trigger (which my sequencer, an Alesis MMT8 uses)? I can insert them into my sequencer tracks manually if I know what they would look like - it doesn't simply call them CC#49 etc but uses MSB and LSB format as:

Controller: 000:000 (MSB:LSB)

Or do I have to enable a setting in the KP3 before the buttons will respond?

Cheers, Graham

Those 8 buttons only generate and respond to CC events when in Ext. CTRL mode. When in Global/Normal mode, then they just do what you've assigned them to do in the Program Memory, and then you see the CC events of the results.

To do what you want, you could just record what happens when you press those buttons, and send the same things back to it.

Right then, I'll try it then and watch how it actually responds. I thought it was only responding with program changes rather than everything stored in the button, but i'll make a complicated scene on a button and see how much is called up on replay.

OK I've been playing with it and the buttons don't respond as such in Global mode. In External mode they act as controllers, not program buttons. But it's been easy enough to just program into the sequencer control change messages to operate what the buttons can be programmed to operate anyway - I just had to find out what did what to do it. A bit more fiddly than I would have liked but achieved the same end.
