I have been approached to design a MIDI interface for a new instrument. It will use MIDI USB and I have the embedded MCU running a basic MIDI USB stack.
Many of the instrument's parameters need to be under control of a MIDI controller, however, the types and ranges of the parameters do not fit into the well-defined MIDI CC messages.
The approach we are following is to use Non-Registered Parameter Number messages to read/write the instruments parameters.
My question relates to how the controller acquires the current state of the instrument's parameters for display to the user when it starts up. I have read and reread the documents; however, I do not see any method for doing this, other than, reading each control one-by-one.
Is my conclusion correct or is there a better way for the controller to get the current state of the instrument parameters upon startup?
The Stack overflow system prompted with the following question; this answers my question:
How to get a current state of a midi device?
