Surge

Surge combine wavetable and analog-style oscillators with a highly innovative filter array and an abundance of effects.

Specifications :

- General
Synthesis method: Subtractive hybrid
Each patch contain two 'scenes' which are seperate instances of the entire synthesis engine (except effects) that can be used for layering or split patches.
Quick category-based patch-browser

- Factory sounds
914 patches
177 wavetables

- 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 (4 modes), S&H
Most filter-algorithms have been improved in v1.2
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
LFO1 allows envelope retriggering when used as stepsequencer
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
