6-Voice ART Wavetable Generator

Vortex 6 is a polyphonic digital wavetable oscillator that uses the ART pitch control. Its sound generation is based on the legendary PPG wavetable synths of the 80s and even uses the vintage digital audio converters of the original.

Features

• ART Input for Pitch
• 6 independent voice outputs on 3.5mm jacks
• 6 independent Gate outputs on 3.5mm jacks
• 6 voice outs on Polytip connector
• 6 Gate outputs on Polytip connector
• Velocity CV Output on Polytip
• Mix voice output
• Internal ASR envelope for wavetable position with CV
• Wavetable start control with CV
• Internal LFO for vibrato with rate and amount with CV
• Glide amount control with CV

Oscillators

Each voice in the Vortex 6 has an independent hardware digital oscillator and some voice modes can add in detuning or sub octave to the sound. The oscillators use vintage hardware from the 80s and are not based on modern DSP emulations. The VCOs waveform can be controlled with a per voice Morph envelope to move through the tables as voices are triggered. The Position control can also be used to sweep all of the voices at once with external CV. The oscillators can be arranged in various ways. Click the EDIT button (yellow), scroll with the encoder to VOICES, click the button (red) and now scroll through the various modes and hear the results. More on that in the Editing Settings section of the manual.
Each voice VCOs has a separate output and also feeds a combined Mix output.

Wavetables

Vortex 6 loads a table from its internal memory on power up and the LED will be RED indicating edit mode. Turning the encoder loads a new table and the display updates as the new table is loaded (TABLE 12, for example). Vortex 6 uses wavetable files filled with 64 different waveforms that make a ‘table’. It only plays one of the waveforms at a time per voice but it can ‘morph’ through the table creating a seamless blend between the waveforms using the Morph knob and/or external CV.

There are two sources for wavetables: Internal Memory & SD card. Internally are 55 Wavetables that come with the module. The majority of these wavetables have a smooth continuity in the harmonic structure when you sweep through the waves in the table.
