INPUT

ENVELOPE

CHARGE

ACCELERATION

Modulating the DRUM MOD input and opening the 
DRUM MOD potentiometer will also charge the envelope 
depending on the acceleration in the input voltage. If a big 
difference of voltage is registered in a  short amount of 
time, the envelope will charge by a lot (stepped voltage or 
pulse signal) and if smoother signals are detected (triangle 
waveform), it will gradually charge the envelope by smaller 
increments, resulting in an attack envelope shape.

6 “DRUMS”

This patch point can be used as another signal for your 
patch. When any other output is connected to this output, 
it will be passively mixed with the oscillator output and will 
go to the OUT jack. This is most useful for adding more 
power by connecting the NOISES output.

7 NOISES

The NOISES output is another sound output with less tonal 
and shorter noise-glitch bursts that could be potentially 
used as hi-hats.
Triggering of the NOISES output is slightly different to 
the “DRUM” output. On the TRIG IN, the loud envelope is 
produced when transitioning from zone 1 to 2 or from 2 to 3.
