Serge TWS+

SERGE  
Waveshaper  
(TWS+)

 

for Eurorack

The TRIPLE WAVESHAPER (TWS) is a non-
linear modifier which can transform a sawtooth 
wave into a sine wave. This classic module 
incorporates three independent waveshapers 
for modifying synthesizer waveforms or for 
processing signals from preamplified instruments. 
Although originally designed as a waveshaper 
for early Serge oscillators, this module has been 
found to be a excellent modifier of electronic and 
acoustic sounds, and is highly recommended for 
subtle timbral modifications beyond the range of 
simple oscillator/filter patches.

The R*S version extends the classic TWS 
concept:

• 

+1

An additional (4th) waveshaper has been added

 (right after the first / bottom waveshaper) that 

can be dialed in smoothly using the +1 knob. Turned down (CCW) the bottom section acts as in the 
original (as if that additional waveshaper would not exist). Turned up (CW) the bottom section is actually 2 
waveshapers in series.

• 

Switches to link the 3 sections - bottom to top. Using these switches all sections can be set to act in 
series, starting at the bottom and ending at the top, providing the combined effect of 3 to 4 waveshapers 
(or anything in between) using the +1 knob.

• 

Linking only the middle and top section and turning the +1 knob up (to have 2 sections in the bottom) 
allows you to use the module for isntance as 

two independent 2-stage waveshapers

 (using bottom in 

and out for one and middle in and top out for the other) - e.g. for stereo processing. 

The Random*Source version is a licensed and authorized adaption of the original Serge design.
