The Modulators Connections

Each Modulator offers four jacks to be connected to other modules.

WAVE  

r

This jack outputs the selected waveform. Connect this output to a CV-input of any module. Typical applications 
would be modulations of a filter’s cutoff frequency, an oscillator’s pulse width or an oscillator’s pitch.

TRIGGER  

t

This jack outputs a trigger signal with the start of each new wave form cycle, allowing to trigger modules such as 
envelopes, electronic switches or sequencers.

CV  

y

This input allows connecting a positive or negative control voltage (+5 volts to -5 volts) to modulate the 
Modulator’s frequency. With 

SYNC or CLK being active for the respective Modulator, this CV will modulate the 

phase shift or the clock division. The control voltage is added respectively subtracted from the current value set 
with 

SPEED/PHASE

 

w

. However, it is not possible to exceed a frequency of 100Hz.

RESET  

u

This input allows connecting a gate/trigger signal that immediate resets the wave form to its start point. With 
the modulation speed matched to a song tempo, sending reset commands every bar, allow to achieve long term 
beat-synchronized modulations.
