VestApps is a suite of 8 browser instruments by deciBelboy. All eight live together in VestStudio, one tab, all instruments, a mixer, a recorder, and a master recorder. No download. No account.
Getting started
Open VestStudio
Go to the VestApps home page and click Launch Studio. If it's your first visit you'll be asked to pick a symbol, that's the member gate. All eight instruments load in a single tab.
Hit ▶ Play
Press the glowing Play button in the top bar. Acid, Drum and Seq start immediately at full volume, and the other five instruments are silent by default so you're not hit with a wall of noise.
Swipe and tap
Swipe left/right to move between the 8 instruments. Tap the layer button (top right) to switch between Instruments, Mixer, Tape and MIDI layers. Or scroll up from any instrument to reach the Mixer.
Set BPM and scale
The transport bar at the top controls BPM, key and scale globally. All instruments follow these settings. Change them while playing and everything updates in real time.
VestStudio — how it's laid out
VestStudio organises everything into four layers stacked vertically, and eight instruments side by side in the instrument layer. You move around by swiping and tapping.
The layer button in the top-right of the transport bar shows your current layer and cycles through them on each tap. It glows green so you can always find it. Alternatively, scroll/swipe up from the instrument layer to reach Mixer, then Tape, then MIDI.
Swipe left / right
Move between all 8 instruments by swiping horizontally. The nav strip at the top of each instrument shows the instrument name and accent colour. The sequence is: Acid → Arp → Chord → Drum → Glitch → Karplus → Pulse → Seq (and wraps).
Scroll up from instruments
Swipe up from any instrument to reach the 8-channel mixer. Each instrument has its own fader, mute and solo button. By default only Acid, Drum and Seq are active, bring others up as you need them.
Session recorder
Scroll up from the Mixer to reach the Tape layer. Arm the recorder, hit Play, and it captures the full stereo mix. Download as 24-bit WAV or 192 kbps MP3. The master recorder also exports a polished mastered version.
Hardware control
Double-swipe up from the Tape layer to reach MIDI Learn. Connect a MIDI controller, then assign any hardware knob or pad to any instrument parameter, volume, filter cutoff, BPM and more.
The instruments
All eight instruments live in the carousel. Tap one below to see how it works. Each instrument's fader in the Mixer controls its volume in the mix independently, bring instruments in and out without stopping playback.
The Mixer
The Mixer is an 8-channel audio router. Each channel corresponds to one instrument. Swipe up from the Instruments layer to reach it, or tap the layer button until it reads "Mixer".
Drag up/down to set each instrument's volume. Double-tap a fader to reset it to unity (85). Max is 150, useful for boosting quieter instruments.
M silences a channel without moving its fader. S solos one channel so only that instrument is audible, useful for checking a part in isolation.
Each channel has a destination selector. Route any instrument to a numbered output track, or leave it on Monitor Only for live output only.
When you press Play for the first time, the mixer automatically sets a starting mix. Acid, Drum and Seq come up at full volume, and the other five are at zero. This gives you a working drum-bass-melody groove immediately. Bring up other instruments by dragging their faders when you're ready.

| Ch 2 | ArpVest | 0 | Silent |
| Ch 3 | ChordVest | 0 | Silent |
| Ch 4 | DrumVest | 85 | ● Active |

| Ch 8 | SeqVest | 85 | ● Active |
Recording
VestStudio has two ways to capture your session: the Tape layer records the live stereo mix, and the Master Recorder captures a processed, mastered version of everything.
Swipe up to the Tape layer. Arm the recorder with the ARM button, it pulses when ready. Press Play and recording starts on the downbeat. Stop to finish. Download as WAV or MP3.
Also in the Tape layer. Runs a mastering chain of EQ, compression, brickwall limiter and normalise, then exports a polished stereo file ready to share. Separate from the raw tape recording.
Beginner tips
Press Play as soon as VestStudio loads. Acid, Drum and Seq are already up in the mix, giving you a working groove in seconds. Tweak from there.
Swipe up to the Mixer and drag up a fader to bring in a new instrument. Karplus or Arp over the top of the default three is a good next step.
Try switching Key or Scale in the transport bar while playing. All instruments that follow the global scale update immediately, a quick way to shift the mood of the whole session.
The green glowing button top-right cycles through Instruments → Mixer → Tape → MIDI. Faster than swiping when you know where you're going.
Hit randomise or regen inside any instrument to change the pattern. Nothing is permanent until you record, so explore without fear.
Arm the Tape recorder before you start tweaking. You never know when something magical will happen, it's always running when armed and Play is pressed.
Try the PING, RAIN or SNAKE play modes in SeqVest for non-linear melodies. The play mode bar sits just above the step grid, tap any mode while the sequencer runs.
Got a hardware controller? Swipe up to the MIDI layer and use MIDI Learn to map any knob or pad to any parameter across all eight instruments simultaneously.
