HOW CAN I RUN 2 MIDI CONTROLLERS AT ONE TIME?

I have a casio PX 130 and am using that as midi controller set with default midi output 1 routed into true piano on sonar X1. I have M-audio key rig 49 set to output 2 routed to Roland Groove synth. They both work great when played alone. As soon as I click related track. but then the other stops working. cant get them both to work at one time?

I think we'd have to have more info on the Casio unit. Output 2 on the M-Audio pretty much is the same as output 2 on a PCR or A Pro I would think. So, if you use output 1 on a unit for note and expression input and ouput 2 for control messages- midi control on the Casio unit you would have to do the same. Control channel 0, control channel 1. I think the M-Audio unit might be more compatible with the workings of Sonar. I have a V 700 C and PCR 800 working together in Sonar. Since the V700 C is motorized, adjusting the PCR 800 activates and changes the V 700 C and visa-versa. The bottom line is getting your control channels on the same channel.
