#PatchMatrix

#a JACK patchbay in flow matrix style

builds.sr.ht status

A simple graphical JACK patchbay that tries to unite the best of both worlds:

  • Fast patching and uncluttered port representation of a matrix patchbay
  • Excellent representation of signal flow of a flow canvas patchbay

It additionally features tightly embedded graphical mixer clients automatable with JACK MIDI/OSC.

#Automation
#MIDI

PatchMatrix mixer clients (AUDIO + MIDI) each have an additional JACK MIDI automation port through which users can automate mixer matrix gains sample-accurately.

Currently, users have to send multiple MIDI messages for a single gain change in a stateful transactional manner.

  • NRPN-LSB: set index of sink port column (optional)
  • NRPN-MSB: set index of source port row (optional)
  • DATA-LSB: set lower 7 bits of gain (optional)
  • DATA-MSB: set higher 7 bits of gain (mandatory)

DATA-MSB finalizes one transaction and sets gain to new value for currently set sink/source port indexes.

#OSC

PatchMatrix mixer clients (AUDIO + MIDI) additionaly support JACK OSC automation through which users can automate mixer matrix gains sample-accurately.

/patchmatrix/mixer iif (source index) (sink index) (gain in mBFS [-3600,3600])
