Hello,
I'm not familiar with either device you mention.
However, please note that many different devices use lsb and msb control changes to select banks and patches, the BIG problem is that they do not all use exactly the same method, so CC instructions that work on one device may not work on another. I recently looked at something relating to a Roland SC device, and I noted that it was slightly different to my Yamaha MU90r, even though many of the sounds were similar.
The only way I think you can get around this is to set different devices to receive midi on different channels, and make sure you send the right Bank Select commands on the correct channel, so that one device will not receive commands intended for the other device.
