Q169 

 Osc+

 

 

Oct 25, 2021

 

The Q169 Osc+ module combines 

two audio oscillators offering an amazing 

array of cross

-

modulation possibilities, along 

with an LFO, envelope generator and sam-

ple

-

and

-

hold functions 

-

 all gracefully orga-

nized on a triple

-

wide 5U panel.

 

 

 

 

Osc+ can be used as a dual oscillator 

in a traditional synth patch, as a stand

-

alone 

voice, as a pair of FM operators for additive 

synthesis, as independent functions, or as a 

complex modulation source.

 

 Go from tame 

to chaos with the turn of a knob. 

 

 

Both audio oscillators are paired with a VC 

amplifier, and each can modulate the others 

pitch, pulse width and amplitude at the same 

time and in variable amounts.

 

 A cross

-

modulation extravaganza!

 

 

The Q169 is the equivalent of 10 modules 

and 20 patch cables arranged in a musically

-

useful and understandable way.

 

 Configura-

tions you probably wouldn't patch naturally 

are easily accessible.

 

 Osc+ is com-

plexity dignified. 

 

 

The optional Q168 Aid module provides 

patch points for LFO waveforms, the enve-

lope, noise, S&H and a multi

-

purpose invert-

able attenuator.
