Read full description

MidiDeep is a real-time MIDI processor. It makes no sound of its own: it reshapes what you play before your instruments ever hear it. You build a chain of effects, block by block, and you hear the result straight away. THE BLOCKS Chord — builds a diatonic chord from a single note. Degrees, inversions, sus2, sus4, sixths, sevenths, ninths, and an octave setting per block. Arpeggio — arpeggiates held notes. Six directions, divisions from whole note to 64th, gate, swing, octaves, latch, transpose. Steps — a polyphonic step sequencer, up to sixteen steps. Per step: semitone, length, ratchet, velocity, tie. Delay — synchronised MIDI repeats. Harmonize — parallel voices. Every block runs on its own internal clock or follows the MIDI clock of your sequencer. KEY AND SCALE One tonic and one scale shared by the whole chain. Fourteen scales, from major to diminished by way of the pentatonics and whole tone. Notes outside the scale are pulled to the nearest one, so you never play a wrong note. MULTIPLE TIMELINES Open as many TimeLines as you need — up to four on iPhone and iPad, up to eight windows on Mac. Each one is independent: its own effect chain, its own channel filters, its own clock, its own MIDI ports. Each TimeLine shows up as a separate port in your DAW — Ableton Live, Logic Pro or any other MIDI host. Preferences and presets stay shared across all of them. CONNECTIONS A virtual MIDI port for other apps on your device. USB MIDI interfaces. Network MIDI to your other machines. BLE MIDI. Input channel filtering, output channel remapping, and a matrix that decides, for each destination, what goes out: notes, clock, controllers. MACROS AND PRESETS Four macros, assignable to any parameter and drivable by CC from your controller. One preset per effect, plus patches that recall the entire chain. ONE PURCHASE, ALL YOUR DEVICES MidiDeep is a Universal Purchase: buy it on iPhone or iPad and it's on your Mac too; buy it on Mac and it follows you to iOS.

NEW IN 5.0 — PLAY, PRACTISE AND CONVERT - Instrument voices: every part plays with a voice chosen by its General MIDI program family (piano, organ, guitar, bass, strings, brass, winds, synths) and channel 10 plays a drum kit. The voices are Midiary's own sounds; they sketch the arrangement rather than reproduce a General MIDI sound set. - Practice & mix: mute or solo any part, change speed from 25% to 200% without changing pitch, shift the key up or down 12 semitones for singers, and loop any range of bars. - Play to MIDI gear: send the file to a USB or Bluetooth MIDI keyboard, module or interface, with its own program changes. SysEx is sent only if you turn it on. - Key and chords: an estimated key and a chord for every bar, with a shareable chord chart. Tap a bar to play from it. - Lyrics and karaoke: lyric events and .kar files follow playback line by line. - File tools: convert format 1 to format 0 for keyboards, arrangers and player pianos, or split a file into one track per channel for your DAW. Set or scale the tempo, change resolution, set a channel's General MIDI instrument, rename, move or delete tracks. Every change is verified and undoable. - Extract: copy a range of bars and the parts you choose into a new MIDI file, with tempo and sounds set up at its start. - Audio export: render M4A or WAV with the current mix, key and speed — a practice backing track in seconds. - Bars and beats throughout: event list, note list, piano roll grid and a playhead. - Open MIDI files from Files, Mail or other apps, use Shortcuts actions (file info, format conversion, transpose, tempo), and iPad keyboard shortcuts. Midiary is an offline studio for Standard MIDI Files on iPhone and iPad. Your imported original always stays intact. MAKE MUSICAL CORRECTIONS Select tracks and channels, transpose, adjust velocity, or move note starts toward straight and triplet grids with variable strength. Drum protection keeps channel 10 out of batch edits. EDIT THE EXACT NOTE Search by pitch, filter and page through long files. Change a note's pitch, velocity, start and duration. Review the actual changes before saving; ambiguous overlaps and unsafe edits are blocked with an explanation. GROOVE BENCH Extract the timing and velocity feel of a passage and apply it to another part with separate timing and dynamics strengths. Up to 64 templates are kept on the device. KEEP THE ORIGINAL Imported MIDI bytes stay unchanged. Edits save locally with undo and redo that survive closing the app, up to 20 steps within 48 MB. Restore the original as an undoable step. Damaged sessions are preserved for recovery. INSPECT THE FILE Tracks with their instruments, channels and note ranges; tempo map; time and key signatures; markers; structural findings; a channel-coloured piano roll; and an event desk with bar, time and tick. Metrical and SMPTE timing and format 2 sequences are supported. EXPORT YOUR WORK Share the untouched original, the edited MIDI, a cleaned copy with missing End-of-Track events added and hanging notes closed, an event CSV, or rendered audio. Start with your own .mid, .midi or .kar file, or open the bundled piano sample or the band sample with lyrics. Imports support up to 8 MB, 1,024 tracks and 100,000 events. Playback runs in the foreground. No account, subscription, in-app purchase, advertising or tracking. Files and editing sessions stay on your device unless you export or share them. Midiary does not record from the microphone. Bluetooth is used only if you open Bluetooth MIDI pairing.
