Subtractive hybrid synthesizer.

Specs:

General

• Synthesis method: Subtractive hybrid
• Each patch contain two 'scenes' which are seperate instances of the enitre synthesis engine (except effects) that can be used for layering or split patches.
• Category based patch-browser that is fast to use

Oscillators

• 3 oscillators/voice
• 5 versatile oscillator algorithms:
• Classic, Sinus, Wavetable, S/H Noise and Audio-input

• The classic oscillator is a morphable pulse/saw/dualsaw oscillator with a sub-oscillator and self-sync.
• Most algorithms (all except sinus and audio-input) offer up to 16-voice unison at the oscillator level.
• Oscillator FM/ringmodulation
• All oscillator algorithms are band-limited yet they still cover the entire audible spectrum.
• Noise generator with variable spectrum

Filterblock

• Two filter-units with arrangeable in 7 different configurations
• Feedback loop
• Available filter-algorithms: LP12, LP24, LP24L (ladder filter with 1-4 poles), HP12, HP24, BP, Notch, Comb+, Comb-
• Waveshaper (5 shapes)

Modulation

• 12 LFO-units available to each voice (6 are running on each voice and 6 are shared for the scene)
• DAHDSR envelope generators on every LFO-unit
• 7 deformable LFO-waveforms + 1 drawable/stepsequencer waveform
• Extremely fast and flexible modulation routing. Almost every continuous parameter can be modulated.

Effects

• 8 effect units arranged as 2 inserts/scene, 2 sends and 2 master effects
• 9 top-quality algorithms: Delay, Reverb, Chorus, Phaser, EQ, Distortion, Conditioner (EQ, stereo-image control & limiter), Rotary speaker, Frequency shifter

New in v1.5.3

• Fixes compatibility issues with Mac OS X 10.6 (Snow Leopard):
• AU: Fixed bug that prevented surge from passing the AUVAL tool in Snow Leopard. As a result, it wouldn't load in Logic.
• VST: Fixed crash caused by Snow Leopard no longer allowed setting the SSE control register directly.
