System 15 - Getting Started
CONNECTION
To connect the System 15 to your system, please consult the connection guides in specic patches.
HARDWARE SETUP
Make all the connections in your system. Keep the System 15 power turned o when making any connections.
Ensure your sound system is turned down.
Turn on the System 15 before turning on any power ampliers and turn it o last. This will help prevent any turn on or turn o “pops or thumps” in your speakers.
WARM UP TIME
We recommend leaving 30 minutes or more time for the System 15 to warm up before recording or live performance. (Longer if it has been brought in from the cold.)
This will allow the precision circuits time to reach their normal operating temperature and tuned performance.

This patch allows a delayed vibrato eect to fade in when a note is held.
The external keyboard controls the pitch and triggering of notes via the CM1A MIDI Interface. As this can be switched between v-trigger and s-trigger then s-trigger
should be selected and the 961 Interface need not be used.
Pitch CV is fed to one of the 921As, which daisy chain to the 921B VCOs. The selected waveform from each oscillator is fed to the CP3A-M mixer; which then feeds the
904A LPF. S-triggers are fed to a multiple, and then to the 911s’ s-trigger inputs
The output of the 904A LPF is fed to one of the 902 VCAs, which feeds out to your mixer, amplier or DAW. This VCA is controlled by the rst 911 EG. The second 911 EG
controls the second 902 VCA.
The second 902 VCA signal input is fed from the 921 LFO. Its output is fed to one of the CP35 multiples, whose outputs feed the DC Modulation inputs of the 921B VCOs
The second 911 should have a long attack time and full sustain.
So long as the rst 911 has a long sustain time, when a note is held a vibrato eect will fade in slowly. When notes are played legato there is little or no vibrato
Space Rock
The pink noise feeding the 904B produces a swept wind eec t, that can be altered with the Fixed Control Voltage
Altering the Fixed Control Voltage of the 904A also produces interesting eects
The CP3A-M balances the two signals, as an alternative feed the outputs of the two lters direct to two mixer or amplier channels. Both sounds benet from a lot
of echo!

Control settings are very important for this patch.
Regeneration on the 904A must be set to 9 or 10 to force the lter to self-oscillate
The 921A should have Octave selected and the frequency control set to -6
The 921Bs should be set to ‘Lo’ – these oscillators provide the sweep to the lters
The 921 should be set to ‘Sub’ – this is the main modulation for the self-oscillating lter, and manual alteration of the Frequency control helps to produce the
classic sound.
MIDI OutTo mixer/amplier/DAW
This sound uses Pulse Width Modulation to a pair of oscillators, one of which should be slightly detuned to fatten the sound.

The detuned 921B VCOs give a fat sound, whose timbre changes constantly at the speed of the 921 sine wave – the 921 should be in Sub mode, speed can be adjusted
to suit.
The sound comes from the 904A LPF, whose Fixed Control Voltage and Regeneration can be set to whatever suits your aim, plus modulation from the second 911 EG.
EG settings can be adjusted to suit for the main part of the sound, although medium to high levels on T2 (decay), T3 (release) and E sus(tain) are recommended.
The second EG should have a medium length T1 (attack), medium T2 (decay) and minimal T3 (release) and E sus(tain).

This sound uses two 921B VCOs, with dierent waveforms, and sounds best if one is slightly detuned. They both feed the 904A LPF, and their relative levels can be
adjusted with the CP3A-M mixer as required. The 904A’s output is fed to a 902 VCA, whose amplitude is controlled by the 1st 911 EG
To obtain the percussive edge the 911’s settings should be T1 (attack) 2ms, T2 (decay) 200ms, T3 (release) 200ms, E sus(tain) 4 seconds
The 904A is modulated by a slow sine wave from the 921 LFO and by the 2nd 911 EG, which should have settings around T1 (attack) 1 second, T2 (decay) 50ms,
T3 (release) 4 seconds, E sus(tain) 9
