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.

Play 12 traditional Chinese instruments, record a phrase, shape your audio, and continue in a compatible AUv3 host. A breath moves through bamboo. A fingertip wakes a silk string. Bronze rings, a drum answers, and a melody begins. BambooSilk was created for that first musical moment—when an idea is still small, immediate, and alive. Touch the instrument, follow the phrase, record it, then carry it into a larger production without leaving its character behind. FROM ONE TOUCH TO TWELVE INSTRUMENTS Open the app and begin playing. Twelve traditional Chinese instruments are arranged in four families: • Strings: Guqin, Guzheng, Yangqin • Winds: Dizi, Xiao, Suona • Plucked: Pipa, Zhongruan, Sanxian • Percussion: Tanggu, Bianzhong, Paigu Each instrument has its own performance surface. Play multiple notes at once, move between techniques, change octave, and capture a take directly from the portrait interface. Connect a USB MIDI keyboard or pair a Bluetooth MIDI controller to play the selected instrument with velocity, sustain, and pitch bend. A quiet Guqin phrase, a bright Dizi line, a rapid Pipa figure, or the pulse of Paigu can all begin beneath your fingers. LET A RECORDING FIND ITS SPACE Sometimes the story begins outside the app. Import a WAV, AIFF, M4A, or MP3 recording from Files and see it unfold across the waveform. Scrub to the exact moment, listen before and after, then shape warmth, tone, stereo width, echo, resonance, and wet/dry balance until the performance sits naturally in its own space. Your installed AUv3 audio effects can join the same workspace. Scan compatible effects, switch plug-ins, compare with bypass, open a plug-in’s native interface, or use a generic parameter view when needed. TAKE BAMBOOSILK INTO YOUR HOST The standalone app is only the beginning. Three included AUv3 tools let the same musical language continue inside a compatible production host. BambooSilk Effect Give an audio track warmth, tonal shape, stereo space, echo, and a natural tail. Ducking keeps the original performance clear while the effect returns between phrases. Parameters support host automation, preset recall, Mix Lock, A/B comparison, bypass, and state restoration. BambooSilk Instruments Perform all 12 included Chinese instrument timbres from MIDI. It supports 16-voice polyphony, sustain, pitch bend, performance techniques, and an on-screen audition keyboard. Use the MIDI modulation wheel for expressive vibrato on Dizi, Xiao, and Suona. BambooSilk MIDI Scales Turn incoming notes toward Gong, Shang, Jue, Zhi, or Yu pentatonic modes. Choose the root and target instrument, then shape transpose, quantize strength, velocity, timing, variation, and note probability. The chosen instrument can travel downstream through MIDI Program Change. A COMPLETE PATH FOR A MUSICAL IDEA Begin with touch. Save the performance. Refine a recording. Then continue arranging and automating in compatible hosts such as GarageBand, Logic Pro, Cubasis, and AUM. AUv3 availability and routing options depend on the host. An interactive in-app guide helps you get started with touch performance, USB/Bluetooth MIDI, audio polishing, and plug-ins. From bamboo breath to silk resonance, BambooSilk gives traditional colors a place in a modern music workflow. Supports English, Simplified Chinese, Traditional Chinese, Japanese, Spanish, and French.
