FireBird v2.1

Firebird is not just another subtractive synthesizer, it uses a unique synthesis architecture to deliver next-generation sounds. Its innovative user interface provides you with the tools to create impressive sounds with a minimal amount of effort. Featuring an impressive selection of 437 build-in sounds, representing both highly sought-after VA sounds, as well as sounds more specific to Firebird and characterized by its Harmonic Content Morphing synthesis, breathing both life and dynamics into the sounds.

Harmonic Content Morphing (HCM) synthesis
Harmonic Content Morphing synthesis is based on a large, expandable repertoire of standard waves, like saw, pulse, as well as more complex wave material, like multi-waves, trumpets, organs, pads, pianos and voice samples.
These waves are modified in real-time, by for example transposing the wave by one or two octaves and adding it to the original wave, altering its harmonic structure, syncing, compressing or even expanding the frequency domain of the spectrum. Making the wave for example sound more fat using only one oscillator, transforming each wave into a hyper-wave or selecting some cycles of a sample and moving through them over time (comparable to wavetable synthesis).
Any modification of a wave can be modulated producing lively shimmery sounds (remember: using only one oscillator!) With a total of more than 18,000 different spectra available for combination and modulation, Firebird+ gives an almost unlimited amount of timbres to experiment with.

Oscillators
FireBird provides 84 different morphable oscillator types in high sound quality. They sound warm, digital, transparent or completely unique. Additionally 23 spectral manipulations or “modifiers” can be applied to the oscillators. A fat knob doubles or quadruples the number of oscillators giving up to 8 oscillators per voice.
Filters
FireBird comes with 38 different sounding filter types:
Lowpass (6-40dB), Analog, Moog, Vocal, Phaser, Comb, EQ, FM, AM, Resample, Elliptic, ...
FireBird+ provides also more complex characteristics for vocal or M-shape filters. Finally, it gives you ADSR- or LFO-modulated phaser-effects, AM- or FM-modulation.
Effects
FireBird offeres 13 different effect types. The effects section has several reverb and stereo tab delay variations, chorus, ensemble, flanger, and rotary effects as well as combinations.
Firebird comes with an easy-to-use arpeggiator.
