Hi tilia,

The problem that you are describing may be caused by MIDI overload. That is there is to much MIDI data being generated at the same time. If that happens you will get dropped notes. Sometimes increasing your buffers helps. Sometimes you have to either thin the MIDI data and/or slide some MIDI data either back or forward a tick or two at that point.

Do you have a lot of CC data in the song? If so you might want to thin them as MIDI data like aftertouch, pitch bend, CC1, CC7, CC11 etc can clog the data flow.

Do you have a lot of notes at the same time in the song? If so move some a tick or two; you can't tell the difference but your computer can!

Look at your soundcard driver's buffers. A control panel comes with the drivers. For example I have a Roland Octa-capture which is set for 64 samples when I record; this gives me a very low latency of 5.1 ms. However this can clog the MIDI data during playback so I set the buffer to 512 samples which gives me 18.5 ms. At 18.5 ms everything plays smoothly, no lost MIDI data, but it is impossible to record at this setting because of latency.

I hope this helps.

I got banned from Weight Watchers for dropping a bag of M&Ms on the floor.
