RNBO and Max with Raspberry Pi - 01 - Setup and Parameters
This video shows how to get started with RNBO and Max with Raspberry Pi. We build a delay patch, set the parameters and then load the patch onto the Raspberry Pi. We then change the parameters from the web interface and from an OSC message. Links and Resources:
