PREFACE 

 
First  of  all,  congratulations  on  the  purchase  of  this  3U  Eurorack  synthesizer 
module.  This  manual  contains  a  condensed  description  of  the  functionality 
and addresses users with a certain level of elementary technical knowledge.  
 
The present 

DTG

 of the CS-8 series is a very flexible and precise fully analogue 

dual-transientgenerator

, with two time bases, each. One of it generates the 

analog transient waveform, the other provides either a 

Gate

 signal (0 V - +5 V) 

of  definite  length,  independently  of  the  input  gate  length 

or

  outputs 

(externally  switchable)  the  incoming  Gate  transition  by  a  definite  delay  time 
(

Delay

).  

 
All times, Gate length/delay, Attack, Decay, Release as well as the Sustain level 
are 

externally  voltage  controllable

.  The  Transient  generator  and  also  the 

Gate  can  be  reset  to  0  V  output  voltage,  separately,  via  a  jack.  A 

Hold

  input 

allows to "freeze" immediately the current voltage output state of the transient 
output until enabling again. A 

Decay-Active

 output becomes "high" active (+5 

V) during the Decay phase. Moreover, it is possible by a jack to set the 

Sustain 

lev el  between  -10  V  and  +10  V

,  meaning  after  achieving  the  regular  final 

value  of  the  attack  phase  (+5V)  the  transient  output  will  further  rise  to  the 
higher Sustain level above (>+5 V) asymptotically with the Decay time (second 
attack phase). 
 
Conclusively,  the  concept  is  well-rounded  by  a 

high-end-VCA

  for 

continuously  negative/positive  output  of  the  transient  waveform  from  -5  V 
(inverse) crossing the exact zero to +10 V final attack value. 
 
Design and implementation meet highest technical standards. The front panel 
is made from powdered and printed piece of aluminium sheet metal of 2 mm 
gauge. The entire design and production work was done in Germany. 
 
Made in Germany
