This is a music sequencer using numeric data. This app is for making MIDI data to send to an another app applied to virtual MIDI. This app doesn't have any sound generation. You have to choose a destination sound module on the setting page. The modules applied to virtual MIDI are listed in MIDI setting page. If you don't select any module, the default sound module is selected by OS. Data are four elements, position, note, length, and velocity. Position shows the time a note start at. Position is displayed in two ways, MEASURE / BEAT / TICK or MEASURE / TICK. The resolution of a beat is 48. Note is pitch.(0-127) Note is displayed in two ways, number (60) or name (C4). Length shows how long a note continues. Length is displayed in two ways, BEAT / TICK or TICK. The resolution of a beat is 48. Velocity shows how strong note is.(0-127) You can change how to display on setting page. Table view: you can see data in the graphic table. Data view: you can see and control numeric data. The view shows position, note, length, velocity from left to right. Direction: you can move the focus cell to up, down, right or left. Ins/Del: you can insert or delete a note. Number: you can enter numbers to a focused cell or increase/decrease a focused number. Play: you can play or stop the song. you can choose to play all tracks or only focused track.

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

Verdict
The clearest difference is review sentiment: ID700 at 88% against NumericTadpole's 0%. ID700 also leads on ratings volume (128 vs 1) and update cadence (monthly vs every 2 months). NumericTadpole's advantage is price ($2.99 vs $12.99) and rating (5.0 vs 4.8). On ads, in-app purchases and monetization model there is nothing between them.

NumericTadpole costs $2.99 and ID700 $12.99 up front. Neither carries in-app purchases, so what you see is what you pay.
NumericTadpole holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: ID700 has 128 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of NumericTadpole's written reviews are positive against 88% of ID700's, so the app with the better star average is not the one people write more warmly about.
NumericTadpole ships an update every 2 months, ID700 monthly. The most recent releases landed on August 12, 2026 and October 8, 2026 respectively.
