MidiDeep
Read full descriptionHide 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 ā builds a diatonic chord from a single note. Degrees, inversions, sus2, sus4, sixths, sevenths, ninths, and an octave setting per block. Arpeggio ā arpeggiates held notes. Six directions, divisions from whole note to 64th, gate, swing, octaves, latch, transpose. Steps ā a polyphonic step sequencer, up to sixteen steps. Per step: semitone, length, ratchet, velocity, tie. Delay ā synchronised MIDI repeats. Harmonize ā 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 ā 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 ā 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.

Your phone, as the controller you actually wanted. Midiboard turns an iPhone into a Bluetooth MIDI controller you lay out yourself. Drop a widget on the grid, drag it where your hand goes, size it to the reach you actually have. Save the screen, build the next one, and flip between them with one tap while the song is running. Every other phone controller hands you someone else's idea of a surface. This one hands you the grid. BUILD THE SURFACE ⢠Pad grids of any size, tuned chromatically or in fourths, fifths, thirds or octaves ā a grid in fourths keeps every chord shape the same wherever you move it ⢠Keyboards of any span, starting on any note, with glissando between keys ⢠Chord buttons you write note by note. C, E, G#, D is as valid as a minor triad ⢠Pitch and mod wheels shaped like the ones beside your keyboard, plus 270° arcs and endless rotaries ⢠Faders and two-axis XY pads, with relative pickup so grabbing one mid-song does not throw the sound ⢠Step sequencers where every step names the note it plays, each with its own run button ⢠Footswitch banks where exactly one lamp is lit ā press a switch and the last one goes out, so a glance tells you which preset you are actually on ⢠Transpose controls that move a group of widgets, so a bass bank and a lead move independently on the same page PLAY IT ⢠Set a key per widget: notes outside it either step back but stay playable, or snap into the key ⢠Poly, mono, legato and glide, per widget ⢠A clock with tap tempo, MIDI clock out, note repeat and an arpeggiator ā or follow your computer's tempo instead ⢠Set the travel of any control, so a fader only ever moves between two settings that are useful on the other end ⢠Panic always within reach, and haptics you can tune per control KEEP IT ⢠As many saved layouts as you like. Export one to a file, send it to someone, import theirs ⢠Two colour palettes, and note names that match whatever your software calls them CONNECTS TO WHATEVER YOU PLAY Two routes, and you pick the one your rig has. Over Bluetooth LE MIDI, Mac, iPad and iPhone connect directly and Windows pairs through a Bluetooth MIDI bridge. Over Wi-Fi it is an RTP-MIDI session ā built into macOS, and on Windows through rtpMIDI ā which is the one to reach for when Bluetooth is crowded or the computer has none. It can also open a MIDI port for other apps on this same phone or iPad. No cable, no dongle, no account, and nothing to sign into. Midiboard collects nothing: no analytics, no crash reporting, no accounts, no tracking. Over Wi-Fi it uses your local network to reach the computer you chose, and the only thing it ever puts on it is MIDI. PRO Midiboard is free, with pad grids, keyboards, faders and labels. Pro adds every other widget, and starts with a free trial; after it, a monthly subscription or a one-time purchase keeps it. The subscription renews monthly unless cancelled at least 24 hours before the end of the period.

Verdict
The clearest difference is price: Midiboard at Free against MidiDeep's $9.99. Midiboard also leads on update cadence (every 4 days vs monthly). MidiDeep's advantage is in-app purchases (none vs 2). On ads, device support and iOS requirement there is nothing between them.
