Spectrum Synthesizer Bundle app for iPhone and iPad

Spectrum is a collection of 3 Audio Unit synthesizers and one Audio Unit effect.

Spectrum is based on popular eurorack synthesizer modules made by Mutable Instruments.

Included are four audio units:

Spectrum - Multi-mode 8-voice polyphonic oscillator featuring 14 high quality oscillator algorithms. Supports MPE.

Modal - Modal synthesis. Bowed, Blowed, and Struck sounds through a 64-band resonator. Also included as an effect.

Resonator - 7 beautiful string generation algorithms. Also included as an effect

Granular - Granular sampler, looper, pitch shifter, reverb effect. Note that Granular is an Audio Unit effect, not an instrument, so it goes in an effect slot.

To use Spectrum, load the Audio Units in your DAW or AU host of choice, like Audiobus, GarageBand or AUM.

Each audiounit also features:
- modulation LFO featuring tempo sync, key reset, reset phase adjustment
- modulation ADSR envelope
- XY touchpad (except on Modal)
- 2-source modulation matrix allowing for complex and evolving patches.
- MIDI CC control of parameters
- Resonator and Modal are also loadable as an AudioUnit effect
