Project update 4 of 5

Oscillographics, USB audio and VCVRack

by Sebastian Holzapfel

One of Tiliqua’s core example projects is xbeam, which is a low-latency digital scope that simulates CRT phosphor decay. Over the last week I’ve been working on combining this with the usb-audio bitstream, to make it possible to both visualize signals in your rack and record / playback audio from your computer, at the same time.

This kind of workflow really shines in combination with Rack, where Tiliqua can act as a low-latency bridge between physical and virtual Eurorack systems. To demonstrate, here’s a tutorial of using Tiliqua as a USB audio bridge and visualizer at the same time:

That’s It!
