Thanks,

Based on the other feed back I had received I was able to get it working under Win7.

I'm using an external USB to MIDI interface instead of the SD4's built in USB. Bit of a pain as I now need to use the external power supply, one more thing to hook up:)

I had an issue with RealBand refusing to recognize the new external USB interface even though it was in the list of output devices. But PG support was able to offer a solution for that.

So now it is working via the external USB to MIDI interface. No more detune and mute sounds from the SD4. So far I have NOT had to send a GM mode command from RealBand. All the MIDIs appear to be working fine via the external interface even with the older SD4 firmware that it came with.

So I would say that it is the USB interface on my SD4 with the version of Firmware that is currently installed on the SD4. At least I have an easier workaround now than using the Virtual Machine with WinXP.

Burt
