Roygbiv (Boards Of Canada) Roland SH-01 Alphatron Oscillion Subtractive Synthesizer VST VST3 AU Plug
1http://alphatron-oscillion.syntheway.net - Probably 'Boards Of Canada' crafted the famous Roygbiv bassline (Album: Music Has the Right to Children, 1998) on a Roland SH-101 that Alphatron Oscillion re-create that in preset 11 BASS SH101 Roygbiv.
Synthesizer Description: Alphatron Oscillion is a polyphonic subtractive synthesizer to produce a vast array of sounds, utilizing three main signal modules: frequency (voltage-controlled oscillator VCO), timbre (voltage-controlled filter VCF) and amplitude (voltage-controlled amplifier VCA).
Four VCOs initiate the sound waveform and control its frequency. It also determines the initial timbre by the waveform option selected (sawtooth or square). The VCF module shapes the timbre via a low-pass filter with cutoff and resonance parameters controlled by an envelope generator. The amplitude of the sound is shaped by the VCA envelope.
It generates iconic vintage synthesizer sounds with distinctive pads, peculiar keys, punchy basses, sparkle leads, creepy effects, charming ambient soundscapes or unearthly and otherworldly atmospheres. Suitable for many genres and styles of music and pliability to custom design over a diverse sonic palette.
Available as a plugin in VST and VST3 64 bit versions for Windows, as well as in Audio Unit for macOS.
Key Features:
• Voltage Controlled Oscillators (VCOs). They will generate the initial sound signal with four voltage controlled oscillators (VCO1, VCO2, VCO3, VCO4), with the following parameters:
o Fine. A fine-tuning knob that tunes the VCOs by a semitone. Gives a wide array of frequencies between the oscillators.
o Octave. The knob to specify octaves above or below the current octave of the VCO by dialing in a range between -2 to +3 octaves.
o Shape. Morphs between sawtooth and square non-sinusoidal waveforms. The sawtooth waveform contains all harmonics of the fundamental pitch of the waveform. The square waveform contains just the odd harmonics.
o Speed. Defines the frequency or speed of the oscillator.
o Gain. This parameter is used to adjust the modulation gain level of each VCO.
• Voltage Controlled Oscillator (VCO) Envelope. Changes the produced frequency. It can be used to modify the attack phase or to create special effect sounds.
• Voltage Controlled Amplifier (VCA) Envelope. Controls the volume or amplitude of the sound with independent control over each ADSR stage over the VCA amplifier that varies its gain depending on a control voltage.
• Voltage Controlled Filter (VCF). A low-pass filter that lets the lower frequencies or harmonics pass unchanged, while it attenuates or reduces the strength of the higher frequencies, offering a simple and effective tone control to shape and color the sound source.
• Voltage Controlled Filter (VCF) Envelope. This section provides control of the filter cutoff frequency over time, with independent control over each ADSR stage.
• Chorus. A 4-voice stereo chorus effect that imparts richness and character to the sound by adding multiple short delays with a slight amount of feedback, making each sound distinct from the original.

• Pitch Bend
• Virtual Keyboard
