Burns Audio has released Spectrum Synthesizer Bundle, a free collection of software synthesizer plugins for iOS, based on classic Mutable Instruments open source designs.
Spectrum is a collection of Audio Unit adaptations of several of Mutable’s popular Eurorack module designs. The collection is made up of four Audio Units – not standalone synths – so they are designed to be used in your DAW or AU host, like Audiobus, GarageBand or AUM.
The collection includes:
- Spectrum – Multi-mode 8-voice polyphonic oscillator featuring 14 high quality oscillator algorithms
- 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.
Each Audio Unit expands on the original MI design by including:
- modulation LFO
- modulation ADSR envelope
- XY touchpad (except on Modal)
- 2-source modulation matrix allowing for complex and evolving patches.
- MIDI CC control of parameters
Spectrum builds on code provided under the MIT open source license by Mutable Instruments.
