I seemingly have an unusual use for usb midi that no one else does. As a solo church musician I often split the keyboard with bass up to C3 and another instrument such as piano, organ ep etc from c#3 and up. On the moxf8 in master mode, I could turn off an external switch for the keyboard range of the bass part. The reason I need this is so that if I'm using a vst such as ravenscroft, truekeys, neosoul keys etc, the piano part isnt layered on top of the bass. I've read through the portion of the manual for zone settings but no matter what I do, whatever vst I'm using plays on the entire keyboard range. Just in case I'm not clear...I want to set up 2 zones/parts using the internal sound (bass) for zone 1 and zone 2 for use with a vst. I'm beginning to think there's no solution for the modx/montage. A solution would be much appreciated.
