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

TB Flowtones Virtual Analog Synthesizer app and AUv3 plug-in Thanks to it's true VA synthesis engine, the use of analog-modelled non-linear filters and extensive modulation options, Flowtones sounds warmer and more analog than digital romplers and wavetable-based synths. TB Flowtones comes as stand-alone app as well as AUv3 plugin. True virtual analog synthesis features: - 4 VCO architecture (two voice layers with two VCOs each) - 4 synthesis engine types, in part modelled after famous analog synthesisers - 36 analog VCO waveforms featuring all classic waveforms and more - All VCO waveforms support pulse width modulation - Full stereo and mono unison modes for each VCO independently - Noise and subharmonic oscillators for each VCO - Unique ring and self-modulation matrix - High-quality, warm, non-linear filters (VCF) with over 30 filter types, including unique multi-resonance filters Modulation features: - Four LFOs with 30 waveforms each - LFOs can modulate other LFOs, including themselves! - Three additional envelope generators, with key velocity modulation - Quick access to modulation strengths through context menus - Hundreds of modulation signal paths available - LFOs can produce noise as waveform to randomly modulate other parameters; for example to simulate slight variations in analog filter parameters as they happen in analog circuits. Pro-grade effects - Studio-quality reverb, delay, and chorus effects - Unique formant filter to add vocal character - Analog and digital distortion / bit crushing effects - Master equaliser and peak limiter for final touch - Non-linear power supply simulation for authentic interaction between notes Step sequencer - Fully integrated, intuitive step sequencer - Can trigger chords and note series / phrases - Can run asynchronously or synchronously to the host - Smart copy/paste of note series to improve workflow - Smart zoom: edit fine details while keeping an overview over the full sequence Presets and intelligent randomizer - Flowtones comes with hundreds of presets to spark your creativity - Intelligent randomizer to explore endless sound synthesis possibilities What you should know: - Licenses acquired for this platform are not compatible with other platforms. - Audio Unit (AUv3) extensions require an iPad mini 2, iPad 4 or later models.

Verdict
The clearest difference is update cadence: ID700 at monthly against TB Flowtones's every 3 months. ID700 also leads on ratings volume (128 vs 39). TB Flowtones's advantage is price ($9.99 vs $12.99) and device support (3 vs 1). On rating, review sentiment, ads and in-app purchases there is nothing between them.
