Hi Dave :) thank you for your reply.

They are very good and obviously done without MIDI.

The problem for MIDI with Linux isn't using just internal or just external equipment, trouble starts when you are using external MIDI devices in combination with recordings of external MIDI devices. I avoid recording guitars etc.. > I agree that more research into MIDI + Linux needs to happen.

The test confirmed what some experienced MIDI users told me. You can't work with MIDI, when using modern Computers, excepted Nuendo, they found a way to use this program which should be the only one, that should be able to do MIDI work, but also with limitations, because of technical issues. I only have Cubase for XT, anyway, I'll check the jitter there too. I guess I can import Qtractors MIDI files by Cubase. >> Has anybody experiences with MIDI by USB and MIDI by D-Sub MPU-401?

I made a test some time ago, it might be different today. I'm still thinking of using Linux or Windows as hard disk recorder and the Atari ST as sequencer. That's why I tested MTC with the Atari ST and other external equipment, I guess it was a Yamaha "drum computer". > I can't involve myself further at this time.

A test scenario that seems to give good information: 1. We play a MIDI groove: Bass, bass drum, snare drum, hi hat 2. We record each instrument on it's own audio track 3. We play e.g. Bass, snare drum, hi hat by the audio tracks and we mute their MIDI tracks, while we mute the audio track for the bass drum and play it's MIDI track. On my machine the groove then isn't a groove any more. And as above-mentioned, other MIDI users confirm this should be for Linux, Windows and MacOS the same. They also don't know such behaviour from the C64 and Atari ST. Just four to the floor, playing MIDI and audio in unison, isn't a good test scenario. I guess my old Asrock mobo with a gameport MIDI had less jitter for Linux.
