Chapter 3: Basics of Analog Synthesis
ANDROMEDA A6 REFERENCE MANUAL 91
7. Last, but not least, we’ll add controller inputs for volume pedal and sustain
pedal. Typically, a volume pedal varies the amplitude (again the “amount”)
of the synth’s output section.
Sustain pedal control is typically routed to the Release portion of the
envelopes: the stage of the envelopes that controls the time it takes for the
fundamental and harmonics to fade out.
Note:The keyboard, pitch bend and vibrato wheels, plus sustain and volume pedals
pictured here as physical controllers can also be incoming MIDI information.
This covers the material for our starting point in introducing the concept of analog
synthesis. In the next Chapter, we’ll apply all of this wonderful knowledge to the
design and operation of the A6, including a comprehensive feature list.
