WBTRK vs MIDIRack

WBTRK is a complete music studio that fits in your pocket — 18 instruments, a sampler, per-note effects, a full mixer, plug-in hosting and MIDI, wrapped in a fast grid workflow that lets you write whole tracks with your thumbs. WRITE • Compose in a grid: 16-step PHRASES stack into CHAINS, chains arrange into a six-channel SONG — the fastest way to sketch on a phone, deep enough to finish • The radial wheel: long-press any cell and rotate to dial in notes, chords, instruments or effects — it previews as you turn • A chord picker with real harmony — maj7, min7, sus, dim — plus select, copy, paste and transpose for whole sections • Loop channels independently, re-root phrases per bar, and let every channel run at its own tempo while staying locked to one clock SOUND — 18 instruments • Classic synths: pulse, saw, triangle, FM, noise, supersaw pad, sub, pluck, wavetable (draw your own cycle), and MODX — a dual-oscillator synth with a 4-LFO modulation matrix • SAMPLER: record from the mic or import audio; trim, normalize, loop, ping-pong, reverse — or beat-chop at transients and play the slices across the keyboard • A singing robot voice with real lyrics, granular clouds over any recording, and struck modal percussion — marimba, bells, steel pan • An ambient section: DRONE, RESONATOR and TEXTURE — beds, drones and weather • AUv3 HOSTING: play your installed instrument plug-ins from the sequencer, and insert effect plug-ins on any channel SHAPE • 29 effects on any note: delay, two reverbs (one runs to thirty seconds), tempo-synced trance gate and autopan, retrigger, chorus, flanger, ring mod, wavefold, bitcrush, slides, vibrato, arps and more • True stereo instruments — place every oscillator in the field • A full mixer: per-channel volume, pan, mute, solo and plug-in inserts • RANDOM dice that re-roll a note on every hit, tables for instant arpeggios, per-instrument swing and scale lock CONNECT • MIDI in (play and record, step or live), MIDI out and MIDI clock for hardware • Ableton Link keeps you in time with other apps and gear KEEP • Render your track to WAV, share songs as files, your session autosaves • A lock-screen player with cover art drawn in your theme • 27 themes plus a full theme editor — from the clean studio default to full retro, hex numbers included • A built-in demo song that shows the whole studio off Everything runs on your device. No account, no ads, no subscription, nothing collected.

MIDIRack is a MIDI toolkit for iPad. Build a custom touch surface from the KB-1 keyboard suite, an all-new sequencer suite, knobs, faders, buttons and more — then unlock a visual MIDI processing graph (one time in-app purchase) and wire it into anything, from a simple custom controller to a full-on groovebox or a self-playing generative composer. Play it on its own and send MIDI anywhere, as an AUv3 plugin in your favourite host or a standalone instrument. THE BASE APP — PERFORMANCE SURFACE Design a custom control surface on a snapping grid: • The KB-1 keyboard suite — piano, diatonic chord pads, scale-locked keyboard, MPE Seaboard ribbon, MPE Strings grid (4ths), and a 4×4 GM drum-pad grid. Each is its own routable node with latch and octave shift. Successor to the KB-1 Expressive Keyboard Suite. • A suite of sequencers — drum, melody, chord, analog and CC step grids and a Matrix note grid, with a moving playhead, swing and microtiming. Per-step velocity, probability, tie and trigger conditions; pattern chaining and 4-pad scene switching for full arrangements; a knob-per-step analog machine that re-roots live as you play. • Knobs, faders, XY pads, buttons and live visualizers — bind to raw MIDI CC or graph parameters. On its own: a rich custom control surface builder — send MIDI and CC to any synth, app or hardware, no graph required. WITH YOUR DESKTOP DAW Expressive MPE hardware costs hundreds. MIDIRack turns the iPad you already own into a controller for Logic, Live, Bitwig, Cubase or any desktop DAW: • Two MPE surfaces — the Seaboard ribbon and the Strings grid send per-note pitch bend, slide and pressure to any MPE-capable instrument on your desk. • A controller that changes per track — MPE ribbon for the lead, drum pads for the beat, chord pads for the progression, faders mapped to CC for a mix move. Rearrange in seconds; save a surface per project. • Sequence it too — clock the step lanes to your DAW and drive its tracks. • Easy to connect — one USB cable to a Mac via IDAM (Inter-Device Audio and MIDI), or wirelessly over Bluetooth MIDI. No driver, no helper app. UNLOCK — MIDI GRAPH (in-app purchase) Wire MIDI In → processors → MIDI Out on a visual canvas: • 60+ node kinds — arpeggiators, scale/key quantizers, transposers, chords, echoes, swing, humanize, euclidean rhythms, random/generative melodies, LFOs, CC tools, an analog knob-per-step sequencer, a Matrix sequencer and a Counter. • Built-in instruments — Synth, Drums, a Sampler and a loop Slicer make sound right in the graph; no external synth required. • Emergence generators — Conway's Game of Life, Turing machine, Wolfram rules, Markov, bouncing balls, Lorenz attractor — for evolving, living patterns. • Presets — factory patches grouped by category (control surfaces, generators, keyboards, utilities): Amen Engine, Starfield, Conway Choir, Turing Bass, Cellular Drums… Save your own. ROUTING & MPE • MIDI Out exposes all 16 channels plus an MPE connector — multitimbral, multi-instrument setups. The built-in synth responds to MPE. • Every keyboard is its own node — process and route each one independently. PLAYS OUT OF THE BOX • Built-in polyphonic synth, drum kit, sampler & slicer or send MIDI to your gear via CoreMIDI and an always-on virtual port.
