Midi notes not triggering, buffer setting involved somehow

[Jono J Grant]

Hi, having an issue with a session file today where many midi notes are not triggering. When I alter the buffer size (using UAD system) it changes it's behavior but  doesn't fix everything. Normally I find buffer size only affects input latency with midi. Strange to have missing notes.

Any idea what could cause this?

Thanks!

I muted an "external insert" I wasn't even using and the issue went away.

Does this explain why the missing midi notes was happening? If so, what might be the reason for it?

Cheers
