Helga - Features

Two Low Frequency Oscillators (LFO)

- Generates sine, up and down ramps, a square wave and a random waveform

- Frequency is midi syncable as well as syncable to an external pulse

Two alias-free Oscillators (VCO)

- Generates any mix of a ramp and a variable duty cycle pulse wave

- The pulse wave duty cycle can be modulated with an LFO or an ENV generator

- The output of both VCO's can be integrated to generate different waveforms

- Sync and ring modulation

Envelope generators (ENV)

- ADSR type (Attach, Decay, Sustain, Release)

- Velocity and aftertouch sensitive

Filter

- Four-pole resonant low-pass/high-pass filter

- Has its own ENV generator for cutoff modulation

- Cutoff frequency can be further modulated with the LFO's and can track the keyboard pitch

Source Mixer

- White-noise source

- External input

Keyboard processor

- 32 voice polyphony max

- Polyphonic and unison mode with portamento

- Pitchbend and modulation wheels

- Microtuning with 12 preset tone scales

Delay Effect

- LFO modulated

- Tempo Syncable
