MPC 2500 doesn´t send Program change ?

Hi, users.

I just scanned the MPC MIDI output by using MIDI OX, and the MPC
just doesn´t send any Program Change, just the MSB/LSB and all
that other stuff....

Besides this, the MPC sends ominous notes who are NOT inside
a sequence......

I tried it with several OSs, all the same.

If this is a bug , then what a shame, akai !!!!!!!

Anyone else who stumbled upon that ?
