Custom component and sub-graph repository for Praxis LIVE (

Custom Components

SubGraph (.pxg) files are a way of reusing and sharing custom components or groups of components for use with Praxis LIVE


Download the latest zip file and extract the contents. Drag .pxg files into your patch from the File Browser tab, or import them into your palette (choose Import from the popup menu on palette categories).


Under active development - lots more to come! Components marked EXPERIMENTAL are in the EXPERIMENTAL folder, and may not be well tested or fully functional.


Components that can be used in any graph (audio, video, tinkerforge, etc.).

  • routing-every.pxg - Allow every n-th signal through.
  • routing-order.pxg - Help order signals through connections - input send to all out-1 connections before out-2 connections.
  • seconds.pxg - Output running time in seconds.
  • tracker.pxg - 4-channel tracker sequencing component (UI editing currently limited - see jazzy synthesis example for usage)
  • array-map.pxg (EXPERIMENTAL) - map a range from 0 to 1 to values in an array.
  • normalize.pxg (EXPERIMENTAL) - normalize incoming signals to between 0 and 1.


Components that can be used in any audio graph.

  • audio-clock.pxg - clock synced to sample time. Time specified in BPM and subdivisions.
  • mono-kit.pxg - simple 6-sample player with triggers and levels. Useful for drum samples.
  • synth-base.pxg - basis for a monophonic synthesizer.
  • synth-duo-osc.pxg - monophonic analog style synthesizer with two oscillators and resonant filter with envelope modulation.
  • synth-pm3.pxg - monophonic phase-modulation synthesizer.


Components that can be used in any video graph.

  • colourbalance.pxg - alter the rgb balance of a video input.
  • xform.pxg - 2D transform (translate, scale, rotate) a video input.
  • framerate.pxg (EXPERIMENTAL) - measure framerate of video passing through component.


Video components that can only be used with the OpenGL renderer.


TinkerForge binding components.

  • rotary-encoder.pxg (EXPERIMENTAL) - binding for the rotary encoder bricklet.

Create your own SubGraph (.pxg) file

Simply select the component(s) you wish to reuse within the patcher window, right-click and select Export to save a PXG file. You can then drag this file from the File Manager into the patcher window, or import into the palette.

Please share!
