planet phatt issue

i have a planet phatt sound module every thing is working fine but how do i get it to load back the correct sounds when i load a sequence up from my mpc?

Assuming that you are using the Planet Phatt in Multi-Mode, with a different preset assigned to some/all of the available 16 MIDI channels, I don't think you can change Multis over MIDI, but maybe you have to send a bank/program change message on each MIDI channel that is being used in the Multi to change each MIDI channel/preset assignment that you are using.

If not using Multi-Mode, and just using a single preset at a time, then just a MIDI bank/program change for the basic MIDI channel that you are using to play that preset.

You should be able to set each MPC track to send a different MIDI Program Change message when the sequence is selected, to the MIDI channel that it is controlling in the Planet Phatt Multi.

Just be aware that it needs a little time to send/receive the program change messages, and might not be ready to playback the newly changed to preset on the first beat of the sequence, if the program change is being sent when the new MPC sequence is changed to.
