CTG-VC, a single complex voltage controlled transient generator The envelope generator provide control voltages that can be used for dynamic change of all voltage controlled parameters, such as; frequency, amplitude, pulse width, cutoff. The most common use is controlling filters cutoff frequency and a voltage controlled amplifiers amplitude in order to achieve dynamic timbre- and level-changes.
All parameters such as attack time, attack hold time, decay time, sustain level, release time and output level are voltage controlled.
The CTG-VC is a complex transient generator with a lot of features, such as; two different shapes for the attack, attack hold (A-HOLD) for more punchier sound than a standard attack, variable decay slope (D-SLOPE) from natural exponential to heavy logarithmic, attack-decay loop (A-D LOOP) and polarized level for outgoing transient signals which means that both outputs levels are controllable in both directions (positive and negative).
A-D LOOP switch activates, when ON, a steady state attack/dacay generator and the rate is determinated by attack/decay time and attack/decay modes.The external signal alone in to the A-D RESTART input start a single A-D transient for every new external signals A-D RESTART period (every shape). The SUSTAIN LEVEL should be in pos. 0.
ZERO RESTART resets (when ON) the remaining release voltage for new gate signal so attack starts always from 0.

ATTACK: Attack time is controlled manually and by an external signal. It has two shapes; logarithmic and exponential, controlled manually by a switch.
ATTACK HOLD: Attack Hold time is controlled manually and by an external signal.
DECAY: Decay time time is controlled manually and by an external signal.
D-SLOPE: Decays shape is controlled manually, from exponential to logarithmic.
SUSTAIN: Sustain level is controlled manually and by an external signal
RELEASE: Decay time time is controlled manually and by an external signal.

here are more information from the manufacture available

Cwejman seem to be new in the industry, but they built their first synthesizer back in 1970. After a long absence, they decided to bring out a new product, which became the high-praised semi-modular S1. This unit along with the S2 established Cwejman in the superior class of synthesizer manufacturers. The modular series is the optimized result of their inventions made with the S1 and S2 units, so You have now more possibilities and individual solutions.
