Description

Audio Link

1. Peak & Hold is controlling the Noise VCA 
In this standard patch the Peak&Hold's 
'Release' output controls the VCA with a 
dynamic envelope shape, while the 
Peak&Hold's 'P+H' output is modulating the 
VCF's cutoff frequency.

Peak&Hold input:
Drum machine

2. 2 Sounds combined
In this example the XR22 VCO FT's 
squarewave output is applied to 'ext VCF In';
the Peak&Hold is modulating the Noise 
VCA's VCF cutoff frequency and the VCA.

3. VCF triggered with impulses
Short impulse signals can be used to trigger
the VCF, generating 'ping' like sounds. Here 
the Peak&Hold's impulse output is used to 
trigger the VCF; its 'P+H' output is 
modulating the filter's cutoff frequency.

4. VCF & VCA working independently
When using the VCA with white noise (or 
Sub F) as signal source, the VCF can be used
completely independent to process another 
signal; or the VCA can generate dynamic 
accents to the 1

st

 (VCF) audio output - by 

shifting the VCA's offset level. Here the 
VCF's audio input is the impulse-triggered 
Delay 1022.

5. 

S

ub F modulating CVs

The 'Sub F' output can be used to modulate 
the VCF cutoff frequency and/or the VCA - 
random sounds such as 'thunder' or 
'crackling' can be generated.
