You can send program change, bank LSB and bank MSB messages directly from the KeyRig keyboard. Please consult the

NRPN/RPNs

Non-registered parameter numbers (NRPN’s) are device-speciﬁc messages that enable you to control synths and sound modules

viaMIDI.TheMIDIspecicationdenesopenparameternumberstoallowmanufacturerstospecifytheirowncontrollers.Themore

allow for 128 values each. (An RPN or NRPN message is made up of two parts: the MSB and the LSB message. Both of these

messages together constitute an RPN or NRPN command.) This allows for 16,384 values in total.
