Synvoiz Overview

Master Volume

Regulates the volume of the Main Out
VCO 1 Coarse

This is the main tuning poti for the VCO. It reaches down to the low frequency range and up to the inaudible spectrum.
VCO 2 Coarse

This is the main tuning poti for the VCO. It reaches down to the low frequency range and up to the inaudible spectrum.
LFO 1 - Rate

Sets the frequency of the LFO. When noise is selected this parameter is inactive. The LFO is pre routed to the Filter Frequency. Try out the Stepwave Parameter in conjunction to create groovy stuff.
LFO 1 waveform

Sets the waveform of LFO 1. You can choose from sawtooth up and down, square, triangle, sinus, exponential triangle like and random. Mind that the setting gets lost when you cut the mains!
LFO 1 Sym

When the LFO is set to a periodic waveform you can shape it so the energy of the positive or negative part of the waveform gets more accented.
LFO 1 Stepwave

The typical scenario for this function is to get Sample and Hold sounds. When you set the LFO to random waveform you can decide with this parameter how often in a second the value of the noise gets sampled / frozen. But you can also use this in combination with a periodic waveform. Turn the knob full right then as starting point. At first it will introduce some quantization into the modulation. Especially with the square wave you can get amazing rhythms only with that one LFO. Unfortunately you can't sync it that easy to MIDI.
LFO 2 Rate

Sets the frequency of the LFO 2 which is pre routed to the PWM Modulation of VCO 1.
LFO 3 Rate

Sets the frequency of the LFO 3 which is pre routed to the PWM Modulation of VCO 2.
MIDI In

The MIDI input will accept notes and mod wheel information. Of course the interface is monophonic, so only the last note is transmitted to the VCOs. The mod wheel is hard routed to the filter frequency. Both ADSRs get triggered by a note but you can interrupt this with the Gate sockets. The MIDI channel is set via an internal button. When you press him the channel of the first message the input gets is the new default channel.
Main Out

Final output of the VCA.
EG 1 Mode

In normal mode the ADSR envelope follows the expected behaviour: attack phase with note on landing at the sustain value after the decay phase reaching the release phase with note off.
In middle position the attack-decay-sustain part is looped until note off where the release fades out.
In below position the whole envelope gets looped - even with note off - it gets faded out according to the release parameter.
EG 2 Mode

In normal mode the ADSR envelope follows the expected behaviour: attack phase with note on landing at the sustain value after the decay phase reaching the release phase with note off.
In middle position the attack-decay-sustain part is looped until note off where the release fades out.
In below position the whole envelope gets looped - even with note off - it gets faded out according to the release parameter.
Activity LED and Button

Lights up every time the envelope gets triggered. It's also a button so you can trigger the envelope manually for troubleshooting or performance reasons.

EG 1 Release

Sets the duration of the release from very short like non-existent to around 2 seconds.
EG 2 Release

Sets the duration of the release from very short like non-existent to around 2 seconds.
EG 1 Sustain

Sets the voltage of the sustain phase which is reached after passing the attack and decay time.
EG 2 Sustain

Sets the voltage of the sustain phase which is reached after passing the attack and decay time.
EG 1 Decay

Sets the amount of time to reach the sustain value.
EG 2 Decay

Sets the amount of time to reach the sustain value.
EG 1 Attack

Sets the amount of time to reach maximum voltage from zero.
EG 2 Attack

Sets the amount of time to reach maximum voltage from zero.
EG 1 Time

Changes the overall timing of the envelope. Higher values will lead to almost inaudible fast curves. Try out the loop mode - you get an additional 4-phase LFO! Now the time parameter changes the overall frequency.
EG 2 Time

Changes the overall timing of the envelope. Higher values will lead to almost inaudible fast curves. Try out the loop mode - you get an additional 4-phase LFO! Now the time parameter changes the overall frequency.
Amp CV 1

Regulates how open the VCA is overall. With this parameter pushed up you can "bypass" the EG 2 which is modulating the VCA. If you want some bleeding of the sound regardless of a note playing or not this is your parameter of choice.
Amp CV 2

Regulates the intensity of the Amp EG on the Main VCA.
Noise Volume

Mixes the analog noise into the VCA section of the VCO 2.
Distortion

A feedback loop in the filter section which leads to heavy distortion. Depends heavily on the filter setting - the effect comes especially with an open filter into play.
Filter Resonance

Self oscillation starts after the middle position in lowpass setting.
Filter Input 1

Sets the level of the first input of the filter which is pre routed to the VCA from the VCO section. After middle position some distortion is introduced.

Osc 2 fine tuning

Knob to fine adjust the tuning of the VCO 2.
Osc 2 Pulse width

Sets the pulse width of the square wave of the VCO 2. Mind that the pwm-square is by default only routed to the VCA 1 modulation input.
Osc 2 Morph

Sets the waveform of the VCO 2. Starting from sinus you can sweep up to sawtooth or square depending on which waveform is selected.
Osc 1 Morph

Osc 1 Pulse width

Main Tune

With this potentiometer you can quickly adjust the tuning of both oscillators. It won't change their frequency-relation.
VCA Mix

Blend between both oscillators with this. If the Bias settings are turned down you won't hear anything in the middle position.
VCA A Bias

Sets the minimum volume which gets through the VCA. You need to turn this clockwise to hear the VCO if the Mix is in middle position.
VCA B Bias

Sets the minimum volume which gets through the VCA. You need to turn this clockwise to hear the VCO if the Mix is in middle position.

  1. you can sync the lfo by midi with the gate IN of env 1 . the gate from the midi interface lays on that socket. you can use it as output to get the gatesignal for syncing the lfo vie the SYNC input 😉 its also possible to merge the gate from the midi interface with an external gate by a cable
