70 ARTURIA – ARP2600– USER’S MANUAL

The ARP 2600V amplifier

In conclusion, here is a scheme that may help you to understand the composition of a

basic sound:

6.2 Complementary modules

6.2.1 The 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 waveform) of a fixed pitch. The only means of stopping this sound

that quickly becomes unsupportable is by lowering the filter cut-off frequency so that it

becomes more and more thick until it disappears; or more simply, to lower the volume of

the amplifier!

• To trigger and stop this sound, 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).

If you don’t have a keyboard, you can play on the ARP2600 V virtual keyboard.
