Limited CC messages at the same time ?

Hi everyone,
I'm using a MPC 1000 as main sequencer (and drum machine) in my live setup, controlling 3 synths with midi out.

So far, everything is really perfect with this machine and this OS (by the way : I didn't tried the AKAI OS)

The only glitch I got before was fixed with last JJOS2XL update. So this is almost perfect.

The only last bug I got is this one :

When I send too many informations at the same frame, it looks like the machine skip some of it. The typical case : I'm sending 2 CC (change program and change bank) + a note , and then the bank does not change.
Or : Sending 1 CC (program change) + a chord of 2 notes, then the note doesn't play when replay.

Since I figured it out, I can skip the problem with delaying on differents frame the different CC messages, there are close enough and nothing is earable, in the end it's no big deal, you just have to know while composing.

But i'm surprised such a powerfull machine can't handle more than 2 CC message.

Or maybe is it just a basic MIDI feature ?

I'm curious, so if anyone experienced that and/or have ideas, let me know

Cheers

you will find it is more likely the synths can not do PC and play note at same time and have nothing to do with MPC

Thanks for your reply.

I thought about this, but this is not the case, since I'm sending the same notes and CC messages from my computer (via sound card) and the synths are doing allright.

It's only happening with the MPC as a sequencer.

well the MPC can send a lot at once, so maybe play with the frame rate of the clock out.
See if that helps. Or just put a tick between note and CCs to that synth. you can barely notice a note starting on 1.0.01 instead, and PCss and CCs before hand. Sys ex is more problematic as it can be larger amount of bytes, but I do not get same thing when i do it with my synths, and sometimes stiuf drops out its usually a lot of sys ex ect, not just a PC & bank select MSB LSB.
