The Beat Kitchen Harmony Wheel is a musician and producer toolkit — a tuner for chords and a measurement device for the vitals of the music in front of you. Point it at your mic or play it over MIDI, and it reads the harmony as it happens — the chord, the key, and the job that chord is doing. Works on piano, guitar, or recorded music with clear harmonic movement. It identifies each chord's role, not just its name, using the Beat Kitchen Ten Chord Toolkit (explained in the guidebook built into the app): the tonic (I) you keep coming back to, the IV that opens things up, the V that wants to resolve, a V/vi setting up a detour, a bVII pulled from the parallel minor. The matching wedge lights up as you play. What it does Hears chords from your mic in real time, right on your device — nothing leaves your phone Labels the wheel by function, not just by chord name: I, ii, IV, V, V/vi, bVII, and the rest Records what you played so you can study the path a progression took Tap any wedge to hear the chord Takes MIDI in, wired or over Bluetooth, with a built-in synth Locks to your key so the wheel orients to the music you're in A Learn tab that walks through what you're looking at If you've reached for a circle of fifths or a key finder before, you're in the same neighborhood — except this one works in real time, while the music is still playing. Producer Tools A tuner and a metronome, built for the studio. Check your tuning. Tap a tempo or let the mic detect it for you, then read it in BPM and in milliseconds for every subdivision — with your own click sound on each one. Watch the beat pulse from across the room and feel it in your pocket with haptics (iPhone). And because the wheel already reads your key in real time, it doubles as a key detector for DJs lining up harmonic transitions. Who it's for Producers, DJs, songwriters, students, and anyone who can tell a progression is doing something to them but can't always say what. You don't need to read music. You need to be curious about why a few chords in a row can move you. It's theory you can hear before you can spell it. Beat Kitchen is a school that teaches harmony by ear and by function first. Harmony Wheel puts that same way of listening on your phone.

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 — 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 — 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 — 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 — built into macOS, and on Windows through rtpMIDI — 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.
