pvj-1.2 / real-time visual instrument

pocket vj.

a pocket VJ instrument you play in real time.

no AI API. no network. premade parametric presets, shaped by your hands and the sound in the room.

smc-mixer / mappedusb-c midi

1 encoders x8
color / speed / zoom / density, 4 free to bind
2 faders x8
layer crossfade / snapshot morph / intensity x6
3 buttons x43
preset jumps / strobe / tap tempo

system

01 / three parts, one cable path

a / engine

iPhone 15 or newer

USB-C. runs audio analysis, Metal shaders and CoreMIDI.

b / bus

powered USB-C hub

HDMI out, MIDI in and charging on one cable.

c / control, ~$60

M-VAVE SMC-Mixer

USB-C MIDI by default. Bluetooth MIDI as fallback.

HDMI: show output, synced
AirPlay: side monitor only, not synced

presets

03 / 5 families, 8-16 parameters each

p1 / particles

p2 / tunnels

p3 / fluids

p4 / grids

p5 / kaleidoscopes

snapshots

save your own variations. recall in one press.

soft takeover

after a recall, a fader acts only once it crosses the stored value. no jumps.

snapshot morph

one fader glides between two snapshots.

spec

04 / technical data

engine	iPhone 15 or newer, USB-C
render	Metal shaders, 60 fps
audio	mic, AVAudioEngine, vDSP FFT
features	bass, mids, highs, beat, BPM, energy
control	CoreMIDI, 8 faders, 8 encoders, 43 buttons
output	HDMI via hub; AirPlay for monitoring
thermal	resolution drops at `thermalState .serious`
network	none. no AI, no API

known issues

hub fails mid-set

Bluetooth MIDI fallback keeps control.

heat on long sets

thermal guard lowers resolution; hub keeps it charged.

presets feel repetitive

two-layer crossfade and snapshot morph.

play light.
