6. Application Examples
6.1. Simple synthesizer standard patch with one envelope generator
This is a simple synthesizer patch with one VCO A-110 that is processed by a VCF (A-124 Wasp filter in this example, but
any other filter may be used) and two VCAs (Dual VCA A-132-3). The first VCA is controlled by the envelope of the ADSR
A-140. The second VCA is controlled by CV2 of the A-190-4 and used for a Midi controlled overall loudness. The VCF
frequency is controlled by both the A-140 envelope (width adjustable level). The dashed blue connections (CV1 A-190-4
→
CV1 In A-110 and Gate A-190-4
→ Gate In A-140) are not required if the bus jumpers of the modules A-110, A-140 and
A-190-4 are installed.
