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

About

OODA

This app offers a unique approach to MIDI sequencing with interactive and semi-generative features. Connect steps with conditional 'wormholes' for structured variation and create melodic variations in real-time without disrupting the groove. Its flexible grid supports various musical applications, from simple melodies to complex generative patterns.

Highlights
  • Record sequences up to 64 steps
  • Interactive step sequencing with wormholes
  • Four independent voices with customizable settings
  • Real-time melodic variation control
  • Flexible grid configuration
  • Standalone and AUv3 host compatibility
  • MIDI clock sync and output

OODA is a fresh take on the classic MIDI step sequencer with interactive and semi-generative enhancements. What makes OODA unique is that you can connect arbitrary steps together using conditional “wormholes” to add structured (or random) variation to your sequences. Another unique feature is that OODA’s underlying model is decoupled from its voices. This allows you to interact with your sequences and create melodic variations in real time without affecting your groove. OODA’s open-ended sequence grid can be easily configured for almost any use case. Anything from simple melodies and bass parts to semi-generative chords and arpeggios, OODA can do it all with a little creativity! Features: - Record sequences up to 64 steps with the in-app keyboard or an external MIDI device - Interact with your sequence on the fly using four “action” buttons - Link together steps using conditional wormholes to create structure and variation - Create complex patterns of melody and rhythm using four independent voices - Change voice speed independent of sequencer speed - Comes with ten factory presets to give you an idea of what OODA is capable of - Explore a deep, yet focused set of parameters - Sequencer Settings - Grid size (4x4 or 8x8) - Sync voices to sequencer rate - Sequencer rate - Sequencer direction - Shift amount (semitones) - Live toggle rests and skips - Wormhole Patcher - Conditionally “reroute” your sequence by connecting arbitrary steps - Per-step wormholes - Destination and normal steps per wormhole - Trig conditions and probability for moving through each wormhole (see below for list) - Voice Settings - Four voices with independent settings - Enable/disable - Rate of play (in beat time from 16 bars to 32nd T) - Includes unique note values based on the Golden Ratio for maximum generative fun! - Length of note (10% to 100%) - Variety of rules for selecting notes from active step (see below for list) - Pitch offset - Unique pattern control for creating rhythms and polymeters, now with step options - Easily add holds, ties, accents (positive and negative), ratchets, and trig conditions - MIDI velocity and channel - Flexible Connectivity - Use in a compatible audio unit host like AUM, or in standalone mode - Control multiple instruments at once with five MIDI outputs - One for all voices together, and one for each voice by itself - Sync to the tempo of other devices using Ableton Link or MIDI clock (standalone) - Send MIDI clock to external synths (standalone, experimental feature) - Connect to Bluetooth MIDI devices - Modulate OODA’s parameters in a compatible AUv3 host (audio unit) - Eight unique MIDI CC outputs derived from OODA’s sequencer model - Sequencer X, Sequencer Y, Sequence Phase, Action OR, and per-voice random - Includes macOS app! IMPORTANT: OODA can be used as a standalone app or as an AUv3 plugin. There are some important differences between the two. The standalone app features a simple, toggleable "Sidekick Synth" so you can quickly experiment with OODA. Of course, you can also send MIDI from the standalone app. Meanwhile, the OODA AUv3 plugin does NOT generate sound. Instead, you use it to send MIDI (note messages) to other apps, plugins, or hardware instruments that do the actual sound generation. AUv3 plugins must be used inside a compatible host.

Verdict

The call

The clearest difference is update cadence: ID700 at monthly against OODA's every 4 months. ID700 also leads on ratings volume (129 vs 38). OODA's advantage is price ($8.99 vs $12.99) and device support (4 vs 1). On rating, review sentiment, ads and in-app purchases there is nothing between them.
