TOPIC:

After some searching I found a promising python library for the 2x4HD that allows some control over the minidsp unit using a raspberry pi attached to the usb port of the minidsp unit. github.com/markubiak/python3-minidsp

In that thread, a dev commented with a list of usb commands for the 2x4HD.

Are the commands the same for the 88A unit? If not, would you be able to provide them?

I'm looking to experiment in creating a remote display and gain knob to control the 88A and also provide read outs of pertinent information.

From what I know of the protocol the main commands should be similar (changing preset, master volume, mute). Where it'll start to differ is going to be on the input/output gains, the different volume meters. the PEQs, FIR, delays, etc.

I started mapping out the commands to control the 2x4HD in an open source project, I'm looking at adding devices but I need testers since I only have a 2x4HD. If you want to test things, open up a github issue. The XML config from the plugin contains most of the data needed to add new devices, but some manual validation is needed.
