Spectrum Synthesizer Bundle0.7

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

Spectrum contains DSP code provided under the MIT open source license by Mutable Instruments.

Version History Fixes song rendering in Garageband and crashes in other DAWs. Double-tap control knob to type in a specific value. Double tap label to reset value. 0.7 08/02/2021 Bug fixes: iPhone users can close popup menus, fixed crash when resizing AU window on 3x pixel density devices. 0.66 01/16/2020 UI improvements. Tap the value of a menu picker to pick from a scrollable menu. Added "quality" setting to Granular - set to low quality for longer 8-second delay buffer. Note that portrait support has been removed for better consistency across devices and sizes. 0.65 01/10/2020 MPE Support! Route Velocity, Aftertouch, Slide, Lift in the modulation matrix. Added dedicated "Velocity depth" knob to apply MIDI velocity to note amplitude. Set default pitch for resonator / modal effect to 48 if no MIDI notes are sent. Settings tab can be saved as default / auto-loaded on new instances. Support for Sustain pedals. Parameter grouping cleaned up. 0.6 10/15/2019 Fixes errors in MIDI CC mapping introduced in 0.4. 0.5 08/27/2019 Lots of new LFO features! Tempo sync, reset on keypress, reset phase adjustment, and visual feedback on LFO shape. All Granular modes now work (fixed Pitch Shift and Spectral Madness), MIDI channel and CC automation can now be changed/disabled from settings menu. Added Aftertouch, "Slide" (CC #74), and Note Release Velocity ("Lift") to mod matrix. MIDI Modulations are now applied per-channel when in OMNI mode. 0.4 08/21/2019 FIXED in 0.3:
- resonator and modal instruments work again in garageband
- added short names
- XY pad modulation from MIDI or AU updates GUI
- MIDI CC list updated
- volume modulation is interpolated, and now works in clouds (for example modulating env -> level) 0.3 07/09/2019 Fixed missing audiounits on iOS versions lower than 12.2.
Fixed MIDI pitchbend and aftertouch modifying all mod matrix parameters at once.
Fixed instability and crashes when loading multiple instances. 0.2 07/06/2019 0.1 07/04/2019
