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

With up to four fully stereo chorus voices, BLEASS Chorus can create everything from subtle movement and gentle thickening to rich, complex modulations, while offering precise control over stereo width, prominence and intensity. In high-pass mode, the input filter is perfect for bringing out the space and airiness within a sound, before the advanced modulation engine makes that airiness shimmer and dance. Switching the filter to shelving mode opens up a whole new range of possibilities, from deliciously warm thickening effects to sparser, thinned-out lo-fi modulations. The detailed and colourful oscilloscope at the centre of the BLEASS Chorus interface shows you at a glance exactly what the plugin is doing. Thanks to the super-efficient BLEASS processing engine, this helpful visualisation won’t come at the expense of your system’s resources. More information and technical specifications available on https://www.bleass.com/chorus/ BLEASS Chorus can be launched as an AUv3 plugin or as a standalone app. BLEASS Chorus is also available for Windows and macOS.

Verdict
The clearest difference is update cadence: ID700 at monthly against BLEASS Chorus's every 10 months. ID700 also leads on ratings volume (128 vs 12) and iOS requirement (12.0 vs 15.0). BLEASS Chorus's advantage is price ($6.99 vs $12.99) and rating (5.0 vs 4.8). On ads, in-app purchases and monetization model there is nothing between them.
