Jonathan Schatz brings West Coast synthesis to iOS in a big way with today's release of ID700. The app is inspired by Berkley engineer Don Buchla, and the unique approach to synthesis that his last name became synonymous with. ID700 is an version of the Buchla 700, with AUv3 and MIDI Polyphonic Expression (MPE).
ID700ID700 is a software synthesizer based on the voice architecture of the Buchla
700. Like many of Don's other designs, sound generation is achieved primarily
via FM synthesis and waveshaping. Each voice is made up of sixteen individual modules:
* four Oscillators
* six Indexes
* two Waves
* one Morph
* one Filter
* one Amplifier
* one Location
The Oscillators, Indexes, and Waves are configured in one of twelve
preset Algorithms, all of which feed into the fixed signal paths of the Morph, Filter, Amplifier, and Location modules.
Each of the Oscillator, Index, Morph, Filter, Amplifier, and Location modules
have their own dedicated complex Envelope for modulation.
The Wave modules provide wavetable synthesis using Chebyshev polynomials and
include additional waveshaping functionality.
Arbitrary tunings are supported via the Scala Tuning File format.
MIDI and MPE are supported (note: not all hosts support MPE).
