The CTG-VC module provides control voltages that can be used for dynamic change of all voltage controlled parameters, such as; frequency, amplitude, pulse width, and cutoff. The most common use is controlling filters' cutoff frequency and 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; different shapes for the attack, attack hold (A-HOLD) for a more punchy sound than with 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).
