i am away from the studio for next two weeks - all underscores.shop orders will be processed from the 24th of july when im back

a r_e_c_u_r video sampler extension circuit – adding knobs, cv and din5 serial midi control to existing r_e_c_u_r unit

SKU: P002 Category:


the i_n_c_u_r circuit is an extension for my existing raspberry pi video sampler project r_e_c_u_r – it will only be useful if you have already built one of these.

using r_e_c_u_r you can run shaders which generate and process video. there are a few different options for controlling the parameters of these shaders – a midi controller connected via usb is the most common. adding i_n_c_u_r to your setup gives you even more options:


  • 4x knobs for physical control over shader parameters
  • 4x cv jacks (0-5v) for sequenced control over shader parameters (from older/analog synths eg eurorack)
  • serial midi din5 jack for sequenced control over shader parameters (from older midi devices)
  • exposes rpi video output through rca jack (rather than the 3.5mm trrs jack on pi )
  • mounting holes and front facing interface parts for easier racking / enclosure building
  • interfacing with rpi through gpio leaving all usb jacks free

this project – like everything in the underscores catalog – is fully open-source hardware – find all the source plus lots more information and guides on the github repo:
