Thank you Gilberto,

I jut tried sending a midi pattern out of ableton to an external drum machine and I have the same issue. It must be a MIDI setup problem on my computer. Does anyone have any idea about this?

Thanks

I'm using OS10.9.4. Are there any settings you think might be at fault?

I've also tried vanilla and pd extended and it is the same with both.

Hi gsagostinho,

Thank you very much for your response. I tested the patch you posted and again only a single note will play at any one time. The same when I sent a chord on separate midi channels. Very puzzling. It mustn't be the patch that is the problem. I've also tried sending midi to ableton via iac bus, and also sending midi directly out of pure data through a sound card and to a hardware drum machine. I had the same issue in both cases, which suggests it isn't a fault outside pd. Any further thoughts of how to tackle this?

Hi,

I've come up against a problem that I can't get my head around. I'm making a 16 step drum sequencer which should be working fine. The problem is that noteout will only send one midi note at a time, meaning that if I have hi hats on 16th notes no other drums will sound. I made a simple chord patch and had the same problem. Is this a bug with noteout? Shouldn't I be able to send a number of midi messages simultaneously?Drums.pd
Thank you in advance
