About

maxChord

Read full description

Chords under your thumb. maxChord turns chord progressions into something you play with one hand. The pads are laid out in whatever key you choose, so everything you touch is already in tune. Tap one to play it. Hold it and drag, and the chord morphs — sevenths, sus, diminished, extensions — each one a direction rather than a menu. Common notes keep ringing while the rest move, so a progression bends instead of jumping. Then build the song. PLAY • Eight chord pads, in key, labelled with roman numerals • Drag any pad in eight directions to morph it live • Chord Lock keeps a variation as the pad's new resting chord • Inversions, slash chords, and automatic voice leading • Three modes: Chords, Arpeggiator, and Lead SEQUENCE • Multi-track sequencer built from chord tiles, not a note grid • Split, resize, and drag tiles to build rhythm by feel • Sixteen patterns, chained into sections to arrange a whole song • Per-track instrument, octave, volume, arpeggiator rate, and effects • Record from the pads or from a MIDI controller in real time SOUND • Sampled instruments: grand piano, upright, Rhodes, Wurlitzer, vibraphone, harp, strings, brass, nylon guitar, church organ, and choir • A fifteen-voice analogue synth bank with real filter envelopes and oscillator detune • Eight effects — drive, filter, chorus, flanger, phaser, tremolo, delay, reverb — per track and across the whole mix, each swept with a single thumb CONNECT • MIDI in and out, including per-track output • Clock sync in both directions • Play maxChord from a controller, or drive Logic, Ableton, or GarageBand from it maxChord has no account, no ads, and no analytics. It does not collect your data, and it works entirely offline. Your songs live on your device and can be exported to a single file whenever you want them somewhere else. Made for people who hear the chord before they can name it. — maxChord Pro unlocks everything after a 3-day free trial: €1.99/month, €9.99/year, or €22.99 once for lifetime access. Subscriptions renew automatically unless cancelled at least 24 hours before the period ends, and can be managed in your Apple Account settings.

About

Midiboard

Features
Read full description

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.
