The totally random sequence of sounds input signal can be derived from a purposes, for instance to achieve powerful modulations or as a "thunder" effect. Keep music live. The input amplifier is followed by an · FET switch (T1) which conducts when it receives a pulse from the gate-pulse generator. At the same time, the ·capacitor connected to the Synthesiser players often require a to be generated. A unit that produces a random pitch control voltage can be realised by utilising a sample and hold circuit. The circuit shown here also produces gate pulses with an independently variable mark/space noise generator or from an LFO (low frequency oscillator). The gain of the input amplifier can be varied between 1 and 10. The amplified input signal is brought out so that it can be used for other 15V(!) 01 ... 05 = 1N4148 I A1 ...
