System 35 – Getting Started

CONNECTION
To connect the System 35 to your system, please refer to the individual patches.

HARDWARE SETUP
Make all the connections in your system. Keep the System 35 power turned off when making any connections. Ensure your sound system is turned down. Turn on the System 35 before turning on any power amplifiers and turn it off last. This will help prevent any turn on or turn off “pops or thumps” in your speakers.

WARM UP TIME
We recommend leaving 30 minutes or more time for the System 35 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.

3rd 911 Output| 2nd  902 Control Input

This patch allows a delayed vibrato effect 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 921A Oscillator Drivers, which daisy chain to the 921B VCOs. The selected waveform from each VCO is fed to one of the CP3A-M mixers; which then feeds the 904A LPF. S-triggers are fed to a multiple, and then to the 911 EGs’ s-trigger inputs
The output of the 904A is fed to one of the 902 VCAs, which feeds out to your mixer, amplifier, or DAW. This VCA is controlled by the first 911 EG. The second 911 feeds the 904A control input. The third 911 EG controls the second 902 VCA.
The second 902 VCA signal input is fed from the 921 LFO. Its output is fed to the fourth input of the C3PA-O so that it can be attenuated if necessary. The C3PA-Os three outputs feed the DC Modulation inputs of the 921 Oscillators
The third 911 should have a long attack time and full sustain.
So long as the first 911 has a long sustain time, when a note is held a vibrato effect will fade in slowly. When notes are played legato there is little or no vibrato

Space Rock

This patch creates two of the classic `space rock’ sounds, and allows them to be mixed together.

Control settings are very important for this patch.
Regeneration on the 904A LPF must be set to 9 or 10 to force the filter to self-oscillate
The 921A should have Octave selected and the frequency control set to -6
The 921B VCOs should be set to ‘Lo’ – these LFOs provide the sweep to the filters
The 921 LFO should be set to ‘Sub’ – this is the main modulation for the self- oscillating filter, and manual alteration of the Frequency control helps to produce the classic sound.
The pink noise feeding the 904B HPF produces a swept wind effect, that can be altered with the Fixed Control Voltage
Altering the Fixed Control Voltage of the 904A LPF also produces interesting effects
The CP3A-M balances the two signals, as an alternative feed the outputs of the two filters direct to two mixer or amplifier channels. Both sounds benefit from a lot of echo!

Mellow Organ

A mellow sound using the 914 FFB that can easily be changed to something more aggressive by changing the settings

Voltage Control (pitch)

Audio
1st 921B Triangle Output| CP3A-M Input 1
2nd 921B Square Output| CP3A-M Input 2
3rd 921B Sine Output| CP3A-M Input 3

CPO3A-M Mixer Output| Your Mixer/Amplifier/DAW
Voltage Control (Amplitude)
CM1A s-trigger Output| 3 x 911 via Multiple
3 x 911 Output| 3 x 902 Control Input

There are three components to this sound. The main organ sound is generated by the first three 921Bs and the 914 FFB. The second comes from the fourth 921B and the 904A LPF and the third from the 923 Pink Noise and the 904B HPF. Certain settings are important, but variations can easily be achieved.

The main organ sound mixes Triangle, Square and Sine waves from three 921Bs. The width control on the 921A would normally be at 50%, giving a pure Square Wave, but can be made more `nasal’ by increasing this or more mellow by decreasing. The basic sound has all waveforms at equal volume, but new sounds can be created by altering the balance.

The settings of the 914 are also important. For the basic sound they should be:

Experiment with different values ­ adding in higher frequencies makes the sound more aggressive, for example.

The 911 EG should have minimum T1 (attack) and T3 (release); long T2 (decay) and E sus(tain)

The second element is a tuned percussive sound on key press. This is derived from the sine wave of the fourth 921B and the 904A LPF. The envelope settings are minimum T1 (attack) and T3 (release) and E sus(tain); 500ms T2 (decay)

The third element is the untuned percussive sound on key press. This is derived from the pink noise of the 923 and the 904B HPF. Envelope settings are minimum T1 (attack) and T3 (release) and E sus(tain); 5ms T2 (decay) . This element should be kept down in the mix

**Expressive Lead #2

-Modular-Synthesizer-with-25-Modules-Expressive-Lead-2.jpg)**

This sound uses Pulse Width Modulation to a pair of oscillators, one of which should be slightly detuned to fatten the sound.

Voltage Control (pitch)

Audio
2 x 921B Square Wave Output| CP3A-M Inputs 1 & 2
CP3AM Output via Multiple| 904A Signal In and 923 High Pass Signal Input
923 High Pass Signal Output| 923 Low Pass Signal Input
904A Signal Output| 1st 902 Signal Input
923 Low Pass Output| 2nd 902 Signal Input
2 x 902 Signal Output| 2nd CP3A-M Mixer Inputs 1 & 2
2nd CP3A-M Output| Your Mixer/Amplifier/DAW
Voltage Control (Amplitude)
CM1A s-trigger Out via Multiple| 2 x 911 s-trigger Input
2 x 911 Output| 2 x 902 Control Input
Voltage Control (Modulation)
921 sine wave Output| 921A Width Input
921A Width Link| 2 x 921B Width Link (in series)

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 main part of the sound comes from the 904A LPF, whose Fixed Control Voltage and Regeneration can be set to whatever suits your aim. The second part of the sound is a bandpass effect from the 923 Filters.
911 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 part of the sound should have a short T2 (decay) and minimal T3 (release) and E sus(tain).
The second part of the sound should be lower in the final mix

Percussive Lead
A simple, two oscillator lead sound with a hard front end and timbral development which is also suitable for melodic sequencing

Voltage Control (pitch)

Audio
1st 921B Triangle wave Output| CP3A-M mixer Input 1
2nd 921B Sawtooth wave Output| CP3A-M mixer Input 2
CP3A-M Output| 904A Signal Input
904A Signal Output| 902 Signal Input
902 Signal Output| Your Mixer/Amplifier/DAW
Voltage Control (Amplitude)
CM1A s-trigger Output via Multiple| 2 x 911 s-trigger Input
1st 911 Output| 902 Control Input
Voltage Control (Modulation)
921 Sine Wave Output| 904A Control Input
2nd 911 Output| 904A Control Input

This sound uses two 921B VCOs, with different 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 first 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
