ID700 - Software Synth Based on the Buchla 700


Available on the App Store here.

"In 1987 Don Buchla released the Buchla 700 synthesizer. It was the next logical step from Don's previous digital synths (the Buchla 400, Touche, Buchla 500) but was also influenced by the synth trends of the 1980's, specifically FM synthesis and the all-in-one workstation concept. As usual, Don was ahead of the curve and the 700 never took off. Very few were sold and even fewer functioning units exist today. I always loved the sound of Don's digital oscillators, and combined with the scarcity of the instrument it seemed like a fun project to recreate it in software and reintroduce its concepts to the world.

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).

The iOS version supports AUv3 and IAA."

Update: demos posted here.
