Midi Control Codes #153/154, Increasing and decreasing MIDI values... Options

[vic_peacock]

Dear friends,

I am not really an expert of MIDI, but I am trying to program a MIDI controller in order to assign some useful functions to buttons, knobs and sliders.

I found that the (extended) MIDI CCs include a "decreasing/increasing" code which takes as parameters: a MIDI CC, the minum value and the maximum value.

My question is:

are there any intrinsic restrictions on the value I can assign to the MIDI CC parameter?

For instance, my controller (M-Audio Ozonic) allows me only to set values in the range 0-127. This prevents me, for example, to program a button that increase/decrease the value of the program-change CC #145 by setting this value as the first parameter of the MIDI CCs #153 and #154.

In general, it seems that it is possible to meta-control only the Standard MIDI CCs as parameter of the extended MIDI CCs. Is it true?

Thank you in advance for your help.

All the best,

Vincenzo
