Four instruments.
One desk.
Apps I built for my own Sundays and sessions — a rehearsal studio for choirs, a stem instrument for the stage, an endless pad machine, and the producer’s reference desk.
The lineup
Pick your instrument
Each one exists because a real Sunday or a real session needed it. I am the user before the developer.
HarmonieMDSoprano · Alto · Tenor · Song
01 · Rehearsal studio
Walk in knowing your part
A rehearsal and multi-track recording studio built for worship teams and choirs. The Music Director records or uploads a song with every vocal harmony part; each singer opens it at home, solos their own line, slows it down, and loops the bridge until it locks.
It speaks choir natively — not tracks 1–8 but Soprano, Alto, Tenor, each with two lanes. Choir Mode is a four-fader practice tool a volunteer learns in ten seconds; MD Mode is a genuine multi-track editor with take comping underneath.
- Per-part solo & faders
- Slow down without pitch change
- Measured round-trip latency
- “Mark practiced” visibility
- Local-first — works offline
- Explore: share arrangements
PerformLive4 decks · stems · scenes
02 · Live performance
Play the stems, not the bounce
A stem player and loop performance instrument for the stage. Load your songs’ stems — drums, bass, keys, vocal, pads — onto a grid of decks, then trigger, mute, layer, and switch in real time. Drop the drums for a breakdown. Hold a pad under a prayer. Jump the set order without fumbling.
Your audio is never touched — no auto-warp, no normalising; the mix your producer built is what the room hears. And it’s built touch-first, so a volunteer can run a service after fifteen minutes.
- Per-stem mute & layers
- Bar-quantised switching
- Scene recall in one tap
- MIDI Learn everywhere
- Untouched-audio principle
- Touch-first targets
Nebula Tide12 keys · zero pitch-shifting
03 · Ambient instrument
An ocean of sound, in every key
Endless, seamless drone pads inside an interface that’s alive. Every preset is a real recording captured in all twelve keys — never pitch-shifted — so E♭ sounds as intentional as C. Keys orbit as floating planets; tap one and the pad crossfades into a new tonal world.
Two stars flank the stage — FX and textures like rain, wind, and swells — and Room, Plate, and Hall reverbs shape the space. Runs standalone on Windows or as a VST3 in your DAW, and the whole interface re-colors itself to match the sound.
- Seamless infinite looping
- 12 real recordings per preset
- FX & texture layers
- Room / Plate / Hall
- Standalone + VST3
- Preset packs, drop-in
PulseRoomDelay · Reverb · EQ · Comp
04 · Producer toolkit
Every mixing answer. One tempo.
The reference desk beside your DAW. Tap in your song’s BPM once and everything follows: tempo-synced delay times, reverb pre-delay and decay that land on the bar grid, EQ boost-and-cut zones painted for 13 instruments, and compression you can finally see as a drawn gain-reduction envelope.
Every number ships with its why, and the app’s own footer says the rest: values are starting points — trust your ears first. Offline, no account, no ads.
- Tap-tempo drives it all
- Click-to-copy every value
- Visual EQ & compression
- Mix chains with reasons
- LUFS & reference tables
- Free · Windows & macOS
Why these exist
Built by someone who has to use them on Sunday
In a real room
Used on actual services and sessions, not in a demo.
Signal, then UI
The engines came before the interfaces — untouched audio, measured latency, honest loops.
Non-technical users
Built so the person operating it can be anyone on the team.
