Filter resonance, noted as “Q”
8.1.3The amplifier or VCA
The amplifier (Voltage Controlled Amplifier) is charged with receiving the audio signal coming from the filter (or directly the one from the oscillator if it is not filtered) to adjust its volume with a knob, before the signal is directed to the speakers.
In conclusion, here is a scheme that may help you to understand the composition of a basic sound:
8.2COMPLIMENTARY MODULES
8.2.1The keyboard
If we hold down a key at this stage, the sound you will get from the speaker will be uniform, without life and without end. In fact, the oscillator delivers a continuous signal (the audio output of a wave form) of a fixed pitch. In the scheme above, the only means of stopping this sound that quickly becomes unsupportable is by lowering the filter
To trigger and stop this sound, and this, at the tone that we want, we use a keyboard, which will be connected to the oscillator. This will “play” as soon as a key is pressed and will mute it as soon as released. Of course, this connection is made through MIDI (it replaces the “gate” type connection of analog synthesizers, which triggers the sound when the key is pressed and stops when released).
In the second case, so that the sound is correctly tuned with the keyboard notes, we need to apply a key follow modulation (replacing the 1Volt/octave control present on most analog synthesizers).
To play the Moog Modular V with a MIDI keyboard, click on the “trigg in” plug of the output VCA and select the “keyboard trigger” function. For more detail, see chapter 5 paragraph 1.1.5 “Output Amplifiers (VCA)”. Next select one of the 4 key follow settings in the display “S1…4,off” on each “Driver” oscillator.
If you don’t have a keyboard, you can play on the Moog Modular V virtual keyboard.
