KORG minilogue xd PROG file parser and pretty printer

mnlgxd.py

# Use this file to parse the structure of your minilogue programs and libraries (sound banks)
# this makes it easy to understand and document a finished sound
# run "python mnlgxd.py test.mnlgxdprog" to print the sound in a program name test.mnlgxdprog
# or "python mnlgxd.py test.mnlgxdlib 1" to print the second sound in the bank named test.mnlgxdlib

I've been working on turning this script into something that can read + write patch files, mostly so I can move a user oscillator to a different slot with out ruing my patches. I'll post it here after I clean it up a bit. Thanks for this gist it's super helpful!

Just wanted to post this here in case anyone is ever looking for it. https://github.com/isnotinvain/minilogue-xd-util

@isnotinvain Great work! Original idea here was to take the graphics from the front panel (manual has a nice one) and draw in the values so that you would have a patch print out as a PDF. Just in case you need another challenge.

cc @buenaonda who just reached out to me and wants to build a GUI like this.

I was thinking maybe https://ctrlr.org/ could be an easy way to do it though you could of course build from scratch. The good news is the MIDI spec for loading / dumping patches is basically the same as the file spec.

Thank you for creating and sharing this script!

I was able to run mnlgxd.py successfully on .mnlgxdprog files, however when running on a .mnlgpreset file, I received the following error:

struct.error: unpack requires a buffer of 1024 bytes

Looking at the .prog_bin files inside of the .mnlgpreset zip archive, I see that the files are only 448 bytes long; .prog_bin files typically decoded by mnlgxd.py are 1024 bytes long.

Are those two different kinds of .prog_bin files?

For reference, the .mnlgpreset file (which includes the 448 bytes .prog_bin files) came from here.

Thanks!

I suppose the file is for the classic minilogue, not the xd
