Download binaries

Build from source code

cd plugins
git clone https://github.com/buzzinglight/Modiy.git
cd Modiy
make

For all versions

Realtime Message Broker

Arduino source code

  • From the webpage opened by Realtime Message Broker, download Arduino source code at the bottom of the page and upload it into an Arduino Mega board.
  • After uploading, quit Arduino and open Settings page from the traybar icon of Realtime Message Broker and select the corresponding Arduino serial port in the list

Wiring

  • Launch VCV Rack with an instance of Modiy plugin on your rack (Realtime Message Broker will be automaticaly launched if you closed it).
  • Pin number for each potentiometers, switches or patching jacks can be found on the admin page of Modiy : right-click —> Open webpage then select Show pin number (selected by default). Wire components in this way (and add as many Arduino MEGA as needed by Modiy) :

OSC commands

If you want to control VCV Rack from OSC (instead of Arduino), here are the main messages to be sent on 57130 port. IDs of potentiometers, switches or patching jacks can be found on the admin page of Modiy : right-click —> Open webpage then select Show IDs.

Potentiometers

/potentiometer/set/absolute <potentiometerId> <abolsute value>
/potentiometer/set/norm <potentiometerId> <value between 0 and 1>
/potentiometer/add/absolute <potentiometerId> <absolute value to be added>
/potentiometer/add/norm <potentiometerId> <value between -1 and 1 to be added>
/potentiometer/reset <potentiometerId>

Switches

/switch <switchId> <0|1 : switch off or on>

Wires

Be careful, only plug outputs on inputs. However, you can permute the arguments in the OSC messages.

/link <jackId source> <jackId destination> <0|1 : remove or add a wire>
/link/clear
