How-to: Use the VA Synth
VA Synth, the Virtual Analog Synthesizer is a new 8-voice polyphonic or monophonic synthesizer for the Soundation Chrome Studio. It features two sawtooth wave oscillators, a nice filter section and some great glide options and sine wave LFO modulation.
1) The two sawtooth oscillators
OSC 1-2OCTAVE: Use the knob to set the overall octave pitch of both oscillator 1 and 2.
TUNE: Use the knob to set the overall tuning of both oscillator 1 and 2.
OSC 2COARSE: Use to set the tuning of the second oscillator in an interval of semitones (half tones).
FINE: Use to fine tune the second oscillator from -50 to +50 cents.
LEVEL: Use to set the volume of the second oscillator.
NOISE: Use to add white noise (independent of the Level knob).
2) The Filter section
CUTOFF: Set the position where the Filter will start to cut off high frequencies.
RESO: Set the amount of resonance (the “ringing”) of the Filter at the cutoff position.
ENV: Set how much the Filter Envelope (yellow envelope knobs) should modulate the Filter Cutoff. The ENV knob can be set from a negative -100% value to a positive +100% value and controls the movement direction of the Filter Cutoff. A positive value means the Cutoff moves from its current position and up, opening up the Cutoff Filter more. A negative value means the Cutoff instead moves in the opposite direction, down from its current position, to cut off even more of the frequencies.
VELO: Set how much the note velocity (note loudness) should modulate the Filter Cutoff. When turned fully left the velocity control of cutoff (and synth amplitude) is disabled.
3) The Envelopes section
The VA Synth has two envelopes. The top row with yellow knobs is the Filter Envelope mentioned above and only control the Filter section if the ENV knob is set to either a positive or negative value. The bottom row of blue coloured knobs is the Amp Envelope and control the level and movement of the synthesizer sound itself.
ATTACK: Set the amount of time it takes for the note to reach maximum level.
DECAY: Set the amount of time it takes for the note to move from maximum level to the sustain level.
SUSTAIN: Set the level (loudness) of the note while it is held.
RELEASE: Set the amount of time it takes for the note to drop to silence after the Sustain level.
4) The Glide section
MODE: Use to select the Glide mode of the synthesizer with polyphonic or monophonic modes.
BEND: Use to set the offset of the initial pitch effect from negative (low pitch) to a positive (high pitch) value.
RATE: Use to set the speed of the pitch glide effect
The Glide Modes:Poly - Polyphonic with 8-voice polyphony
Poly Legato - 8-voice polyphony with pitch glide if a key is held (overlapping notes)
Poly Glide - 8-voice polyphony with pitch glide (without the need to overlap notes)
Mono - Monophonic
Mono Legato - Monophonic with pitch glide if a key is held (overlapping notes)
Mono Glide - Monophonic with pitch glide (without the need to overlap notes)
5) The LFO Section
An LFO, or Low Frequency Oscillator, is used to modulate parts of the synthesizer. The modulation is controlled by a silent sine wave oscillator and will not be heard unless it is actually modulating another part of the synthesizer.
RATE: Set the speed of the sine wave oscillator used for modulation
VIBRATO: Set how much the LFO should modulate the synth pitch using values from 0-100%. Turning the knob left into negative values will create PWM effects (Pulse Width Modulation)
FILTER: Set how much the LFO should modulate the Filter Cutoff.
