The Tiefenrausch is a monophonic synth with over 27 knops and two voltage-controlled oscillators.
The signals go through a 24dB low-pass filter, which is developed as classical transistor cascade. Two envelopes serve for the dynamic sound figuration. A AD envelope is for the filter, and the ADSR envelope is responsible for the voltage-controlled amplifier.
