Hi!

It is difficult to tell just what may be the cause of this, but I can tell you a little of what I have discovered..

Firstly; it does help to move the clock on the tracks, so that not all the MIDI-events happen on the same clock-beat. What is causing the probleem is obviously that the CPU or sound generator gets too much to do.

Could it be that you are using more than 64 tones? Remember that patches can use up to 4 TONES each. This means that all available polyphony will be used up when playing 16 NOTES.

Other thatn that, I think you should check what happens on the clock-beats, and try to move some of the events to other beats.

The last thing to check, is how much ControlChanges are going on. Some of these generate a lot of work for the sound generator, and make it slow down. A Data Thin could solve that.
