Hi guys,
David, I'm just a cheapskate
For the choppy problem, David's suggestion is good, AND also be sure the GS Wavetable is turned off in Composer/Musician. The GS Wavetable interferes with the ASIO driver, and can affect latency as well.
To turn off the GS Wavetable:
1. Open Musician/Composer and click Setup/MIDI Device Configuration.
2. Click on Ports/Select Ports, and UNcheck the box beside GS Wavetable.
3. Click "Ok" to save and exit.
Hopefully that should do it.
ttfn,
Sherry
