Topic: 9632 Midi

I have a 9632 pci card and a Keystation Pro 88 keyboard. I play a Roland TD-3 through the midi in of the 9632. The resulting volume output from any of my drum software is markedly lower via the 9632 input compared to the USB midi in from the keyboard. Is there a reason, or something I'm doing wrong? Thanks, Shep
