ID700 is a hybrid FM/waveshaping software synthesizer based on the voice architecture of the Buchla 700. ID700 runs in standalone mode and as an AUv3 plugin (Logic Pro, GarageBand, AUM, Cubasis 3). HISTORY In 1987 Don Buchla released the Buchla 700 synthesizer. It was the next logical step from Don's previous digital synths (the Buchla 400, Touché, 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. FEATURES * AUv3 and Standalone support on iOS * twelve voices of four operator FM with twelve unique algorithms * fourteen complex envelopes per voice * two hundred professionally designed presets * two waveshapers per voice * preset randomizer * over forty factory wave shapes plus an editor for user created shapes * Scala scale file support with over four thousand included tunings from the Scala scale archive * MPE (MIDI Polyphonic Expression) capability for MPE controllers like the Roli Seabord, Linnstrument, and Sensel Morph * advanced MIDI implementation (including 14-bit CCs and Program Change) * an in-depth manual (60+ pages) is available in the app and from our website * iCloud support for sharing presets, waveshapes, and tunings between devices * up to 16x oversampling

Tera Pro brings together all major sound synthesis methods on one table. No matter if you want to recreate sounds from analogue legends or explore modern digital sounds with FM, Waveshaping or Wavetable synthesis. More can be added by In-App Purchases of new modules. Add some flavour of physical modelling and modules for additive synthesis. Combine them altogether for new sound experiences far beyond your wildest dreams. Tame this overwhelming amount of possibilities with Tera Pros intelligent user interface showing you only exactly what you need, paired with realtime oscilloscopes and level indicators helping you seeing what’s going on. Connect the modules with a flexible routing method without the visual cluttering of real wire cables needed in conventional modular synthesisers FAQ What does Tera Pro have that Tera Synth doesn't have ? 1) Additional Sound Modules - Spectrum oscillator ( borrowed from the heart of Addictive Synth ) - Wave shaper / folder opens the west coast synthesis - Vocal Morphing filter - KARPLUS (aka WaveGuide ) with new "Swarm" mode ( 3 detuned delays ) 2) Revised engine - Analog Polysynth Voice Modelling with characteristic subtle voice variations of timbre, pitch and temporal behaviour to get you "The" Analog Sound. - 128 vs 32 voices polyphony - Seamless Sound Switching: change presets during play without cutting off the sound. - 8 times unison for really heavy ambients - Envelope generators with Buchla style "end of cycle" trigger for generative music - Stack/Split Sounds - New effect section 3) Redesigned User Interface - Collapsible modules for clear view of modular structure - No more nasty popups for LFOs/Envelope generators - Realtime oscilloscopes added to selected modules 4) New Presets - About 1000 additional presets in there.

Verdict
The clearest difference is in-app purchases: ID700 at none against Tera Pro's 6. ID700 also leads on review sentiment (88% vs 69%) and rating (4.8 vs 4.6). Tera Pro's advantage is price ($6.99 vs $12.99) and update cadence (every 5 days vs monthly). On ratings volume, ads and iOS requirement there is nothing between them.
