Anna

Anna is a Hybrid Synthesizer. It came second in the KVR Developer Challenge 2006.

Features:

• Four oscillators capable of complex waveforms, utilizing internal frequency modulation with separate waveforms and frequencies for the carrier and modulator.
• Spread knob on oscillators, running three detuned oscillators internally in the oscillator, resulting in a total of up to 12 oscillators.
• Two multi-mode filters with 14 different modes and internal filter overdrive.
• Pitch tracking of the filters, allows the user to "play" the filters.
• Four multi-mode LFO's with random, waveform and step sequencer modes.
• Four modulation envelopes with basic and multi-point modes, user-defined slopes for each of the stages and looped sustain section.
• Extensive modulation matrix with 16 slots. Modulation sources include oscillator and filter outputs (all modulations are "audio rate").
• Frequency Modulation XY-pad defining the following oscillator frequency modulations: oscillator 1 > 2, 1 > 3, 2 > 3 and 3 > 4.
• Effects section with fully parametric two-band equalizer, two modulated stereo delays with four-band filter control in the feedback loop and cross-feedback between the two delay units and a crusher unit capable of sample rate reduction, bit resolution distortion (not the standard kind, sounds more like a broken transistor radio) and distortion. The order of the effects is user-definable.
• Auto-disabling of unused sections to reduce CPU usage.
