ID700 by Jonathan Schatz

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).

ID700

ID700 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).

Red Sky Lullaby jammed on ID700, and Doug Woods did a live stream exploring the new app.

So true! yummy
I downloaded it and it didn't run on my iPad Mini 2 w the latest os. Such a bummer. You never see this synth outside museums. A whole generation has gone without hearing anything it has been on.

really love the way this sounds, but the controls are so jittery! wish developers would always allow numerical entry or at least a way to adjust the sensitivity of controls.

I had issues getting it to run initially. Then I opened it in AUM, both as a AUand IAA. That fixed it somehow.
