PREFACE
First of all, congratulations on t e purc ase of t is 3U Eurorack synt esizer
module. T is manual contains a condensed description of t e functionality
and addresses users wit a certain level of elementary tec nical knowledge.
T e present DTG of t e CS-8 series is a very flexible and precise fully analogue
dual-transientgenerator, wit two time bases, eac . One of it generates t e
analog transient waveform, t e ot er provides eit er a Gate signal (0 V - +5 V)
of definite lengt , independently of t e input gate lengt or outputs
(externally switc able) t e incoming Gate transition by a definite delay time
(Delay).
All times, Gate lengt /delay, Attack, Decay, Release as well as t e Sustain level
are externally oltage controllable. T e Transient generator and also t e
Gate can be reset to 0 V output voltage, separately, via a jack. A Hold input
allows to "freeze" immediately t e current voltage output state of t e transient
output until enabling again. A Decay-Acti e output becomes " ig " active (+5
V) during t e Decay p ase. Moreover, it is possible by a jack to set t e Sustain
le el between -10 V and +10 V, meaning after ac ieving t e regular final
value of t e attack p ase (+5V) t e transient output will furt er rise to t e
ig er Sustain level above (>+5 V) asymptotically wit t e Decay time (second
attack p ase).
Conclusively, t e concept is well-rounded by a high-end-VCA for
continuously negative/positive output of t e transient waveform from -5 V
(inverse) crossing t e exact zero to +10 V final attack value.
Design and implementation meet ig est tec nical standards. T e front panel
is made from powdered and printed piece of aluminium s eet metal of 2 mm
gauge. T e entire design and production work was done in Germany.
Made in Germany
