ACT doesn't respond to Edirol PCR-M50 Control Data

I'm using an Edirol PCR-50 controller (current Win7-64 driver 1.0) with Sonar X1c. I can't get the ACT template (PCR-M30) to respond to the controller. I'm sure I have it connected properly: IN PORT: PCR 2 OUT PORT: PCR MidiOX confirms data is being sent by both PCR1 (notes) and PCR2 (control data). In Sonar, I watch the level meter. The meter shows green when I play notes. But when I send control data, say a slider or knob from the PCR-M50, the only activity in the level meter is red flashing leds at the top of the meter. It seems that Sonar is getting the control info from PCR2 fine, but it isn't making it into the ACT inputs somehow. Any suggestions appreciated. Thanks!
