I changed from using the M-Audio Fasttrack ultra ASIO driver and Ketron SD2 patch map to the ASIO4ALL driver (12 ms latency), the default patch map, and Forte DXi synth. This combination _works flawlessly_ with both the midi and RT styles used previously.

I then switched to the M-Audio ASIO driver: the RT-melody problem returned. I confirmed this was not due to the Ketron SD2 patch file nor the Ketron SD2 itself. So, it appears to be a direct result of the M-Audio driver (I guess... second opinions welcomed).

The question becomes: what can I do? I have the latest driver version (5.10.0.5100; firmware 1.51). I don't want to buy another hardware audio interface or synth (the Fasttrack is less than 1/2 year old and I'm happy with the Ketron SD2); however, I am unwilling to live with this problem. There are not many things I can (as a user) to change the settings on this driver: I have options for sample rate (currently 44.1 kHz and not changeable), ASIO/WDM buffer size (currently 4096 samples; I tried going down to 512, this didn't help), clock (set to internal not changeable); "enable asio direct monitoring" (currently off; tried turning it on -- didn't help), and "effects" (currently "Echo" with duration, feedback, and volume set to minus infinity. There is "no effect" setting; the default is "Echo"). The driver panel allows monitoring of the eight channels on the Fasttrack. I have the volume sliders for channels 1-2 (mic in, when I use a mic) and channels 5-6 (Ketron in) set to max. There is a set of knobs below each channel labeled "send": channels 1,2,5, and 6 are all set to minus infinity. The master out volume is at max and its return set to minus infinity. That's all I can alter. Anyone see anything that might be wrong with these settings?

Anyone have suggestions on how to proceed?


Thanks for the help!
