5. Patch Ideas/Uses 

 

Feedback Patch 

 

In this patch, we are feeding effects back into themselves in order to create an ambient soundscape. 
The effects are arbitrary, but having a Delay is important. The effects in this patch are a distortion, a 
delay, and a reverb. Each is patched in, and out of the Matrix Mixer. Each output of A, B, and C can 
have a mix of Inputs 1-3 (distortion, delay, and reverb) sent out of it back into the Distortion, Delay, 
and Reverb. Start by mixing the delay into the delay until it feeds back into a squeal, and then back 
off of the mix knob. Then start mixing in (and out) the other effects. This can be a wonderful way to 
create cool transitions in a live environment. Input 4 could be fed from a mixer’s aux send, and when 
one patch is done, a feedback patch could be created while a new patch is made. 
 
 

Feedback Oscillator Patch 

 

In this patch, two oscillators are fed into the AI008 Matrix Mixer. This patch should be doable with any 
voltage controlled oscillator that has CV inputs. The outputs of the Matrix mixer are fed back into the 
oscillators, with one oscillator getting a mix of signals fed back into its Frequency Modulation input, 
and the other oscillator getting a mix of signals fed back into its Frequency Modulation and Pulse 
Width Modulation inputs. The summed A+B+C output, could then be fed to a traditional filter/VCA
