this is true of all midi hardware, not just the mpc. if you try and send/receive too dense of a stream, it will choke, drop data, etc...
this is pretty easy to do with the mpc, as it offers such a large number of tracks. start recording dense realtime cc data on 5-6 tracks and you will run into problems.
it could also be the problem with the receiving hardware as well. the mpc could be sending everything fine but the gear on the other end just can't keep up. either way, you have to learn to work within the limitations of what you have.
thanks for your reply. well I'm ok with working with some limitations but I thought the MPC was exaggerating a bit yesterday : I really wasn't running that much tracks simultaneously (5 maybe?) and I wanted to use one of them to record some filter cutoff action for my Bass Station 2, which resulted most of the time in the Electribe SX1 stopping to play after it played it's loaded pattern once (?). Kind of weird. The more I work with this setup, the more I tend to use separate tracks to send to the same synth (like different notes of a chord, or like in this previous case using one track separately for CC info). I wonder if that can be a source of problems?
I have to take care of what I record exactly on the tracks anyway, I'm especially thinking about aftertouch - I don't have a lot of synths which handle that and it would be cool to find a way to filter this info before it's recorded down to tracks, I'm sure it helps the whole thing to stay stable.
anyway I guess everything will be better with the MPC1000 because of the two MIDI outs and the JJOS interface, which I assume allow you to do those kind of tricks (filtering out the MIDI data for example) more easily
I'd also love to have a nice more step-like sequencer but my priority right now is to get something versatile. I needed some time to get used to it but I like what the MPC500 allows you to do. It just seems quite limited and sometimes over complicated, hence my decision to find something else. MPC1000 looks great for my needs to be honest. I'm sure I could make nice babies with the Elektron gear but it would eat all my money and then I would starve or something.
hey man, getting an MPC1000 as well now, forgetting about new software sequencers for a moment since I just fixed my sammichSID.. really excited to see how I can fit this with the rest of the boxes.
my interest was piqued after I heard this, made on an mpc2500 only: https://fahtunes.bandcamp.com/album/datman-h-ya
