EG WaveSHAPER is the first synthesizer that lets you create your sound with a finger. Draw the waveform on the screen or shape a builtin one, mix it with a classic analog oscillator and a sub oscillator and automate all the knobs with 2 drawable LFOs and 2 ENVs HYBRID WAVESHAPING ENGINE 'Waveshaping is a synthesis-and-transformation technique that turns simple sounds into complex sounds' 2 wavetables can be designed and morphed to create unique and dynamic sounds under your finger, choosing the morph attack and release; complex spectra can be created waveshaping the oscillator and introducing non linear distortion, rich harmonics and a tube-vacuum behaviour. The hybrid Waveshaping/Wavetable engine lets you combine a wavetable oscillator with a classic oscillator and a sub oscillator, to add additional sound layers and depth. LFOs & ENVs 2 Lfo and 2 Envelopes with indipendent time can be assigned to virtually any of the synth parameters. They can also be graphically designed with the touch of your finger or you can choose among the builtin envelopes. OTHER FEATURES - Hybrid Wavetable/Waveshaping engine - Draw your wavetable oscillator with your finger - 100+ presets (Pad, Lead, Bass and Fx) - 30+ builtin waveforms to use and modify - 2 LFOs and 2 ENVs assignable to any parameter - FX: Reverb, Delay and EG Crush - Detune osc to create huge unison sounds - FM and Noise with configurble FM Ratio and Noise eq - VCF and Reso filters - Complete presets management with export and share - Core MIDI: MIDI in, MIDI CC, MIDI channel pressure control - AU3 with full knobs parameters automation - Universal for iPad & iPhone

The next generation of additive synthesis Additive synthesis is a sound synthesis technique that creates timbre by adding sine waves together. The timbre of musical instruments can be considered to consist of multiple harmonic or inharmonic partials or overtones. VirSyn already has a remarkable track record of products ( CUBE, POSEIDON ) trying to make this virtually unlimited synthesis method manageable for creative sound designers and musicians. AddStation is the next step forward giving you a tool to explore completely new sonic territory. The massive amount of sine waves in AddStation - thousands per voice - together with unique morph sequencing blocks blur the frontiers between analog and digital sonic realms. And all this integrated in all relevant iOS production environments especially the emerging AUv3 AudioUnit standard. Synthesis • Fractal additive synthesis • over 170 sound presets • Four parts with 8 Additive Sequence Blocks • Sound morphing • up to 512 partials per voice with independent AD envelopes • harmonic/inharmonic spectra • Ringmodulation • arbitrary filter function and noise spectra • four independent analog style Arpeggiators Effects • Chorus • Phaser • Flanger • Overdrive • Parametric EQ • Echo/Delay • Reverb Global • AUv3 for Host integration • Audiobus 3 compatible (Input slot) with state saving • Support for Ableton Link. • Inter-app audio compatible (Instrument/Generator) • CoreMIDI / Virtual MIDI • Audio recorder.
