A-141-4 is a quad voltage controlled Envelope generator and is primarily planned for polyphonic applications. The module contains four ADSR type voltage controlled envelope generators with exponential curve shapes (charge/discharge curves of a capacitor). Common manual controls and CV inputs with polarizers are available for the parameters Attack (A), Decay (D), Sustain (S) and Release (R). Each of the four envelope generators has available a gate input, a control LED and an envelope output.
The output voltage range for each envelope is 0 – 10V. The time range of Attack/Decay/Release is about 1ms to 30s.
The gate levels in the “high” state have to be at least +5V (up to +12V). The “low” state has to be 0V or less. Only signals with fast rising slopes (“rectangle type”) are suitable as gate signals. Slowly changing signals (e.g. triangle) cannot be used as gate signals.
Application: polyphonic patches (four envelope generators with the same envelope parameters to control four VCFs, VCAs or other modules)
