The self-playing synth for your phone. Press play and it composes; you steer.
This page is the manual, and it is kept up to date here. Last updated 9 September 2026.
The 30 second version
That is the whole thing. You are not arranging loops, you are steering a piece of music while it plays.
Free to try, then a one-off unlock
It plays free for three minutes. After that the sound starts cutting in and out. A single in-app purchase of US$14.99 unlocks uninterrupted play for good. One payment, no subscription. If you move to a new phone, use Restore purchase to bring the unlock across.
It asks for nothing
ARGISH Pocket runs offline. No account, no ads, and it collects no data. Once it is on your phone it never needs to reach a server.
It writes its own music
Press play and ARGISH Pocket composes chords, bass, arpeggio and drums, live, and never quite the same way twice. Your job is to steer it, not to program it.
The wheel
Drag the wheel to conduct. It moves the harmony underneath everything else, so the music follows where you take it.
Five moods
Gentle, Haze, Deep, Still and Epic. Each one retunes the whole instrument at once: the key, the tempo, the drums, the effects and how busy it gets. Tap one and the piece changes character straight away.
Evolve
Leave Evolve on and the piece keeps moving by itself. Switch it off to hold the mood exactly where it is.
Generate
One tap on Generate writes a fresh chord progression in the current mood. Tap it again for another.
More control when you want it
Open the Controls drawer for the full set:
Arrange a whole piece
Set a length from 30 seconds through to endless, pick a dynamics shape (flat, build, rise and fall, swell, or epic climb) and ARGISH Pocket performs that arc for you, building and resolving on its own.
Make it yours
Twelve accent colours to choose from.
What MIDI Out does
ARGISH Pocket can stream its performance, live, to a computer or hardware, so it plays your instruments instead of, or as well as, its own sound. The arrangement is split across four MIDI channels so each part can drive a different instrument:
MIDI Out is off by default. The app behaves exactly as before until you switch it on.
Turn it on
Go to More → MIDI Out. Set Send MIDI to On, and choose what to send: Full, split by part for all four channels, or Chords only. The panel shows the connected device, or "No MIDI device connected" until one is plugged in.
Connect the phone
You need a MIDI link between the phone and whatever will play the notes. There are three ways.
USB to a computer. Plug the phone in with a USB-C cable, then put it into USB MIDI mode: swipe down the "Charging this device via USB" notification, then Use USB for → MIDI. The phone then shows up to the computer as a MIDI device, named after the phone model.
Some phones, notably Honor and Huawei, hide the USB MIDI option. On those, use Bluetooth or a USB MIDI interface instead.
Bluetooth. No cable and no USB-mode switch. On a Mac, open Audio MIDI Setup, then Window → Show MIDI Studio → Bluetooth, and connect the phone. This is the best option when the phone has no USB MIDI mode.
USB to a hardware synth or interface. Run the phone's USB-C into a small USB MIDI interface, then its OUT into the synth's MIDI IN, or straight into a synth's own USB "to host" port. The phone hosts the device and plays it directly.
Receive it in Logic Pro
To play one part quickly:
To split all four parts onto four instruments:
Do not use the External Instrument plugin. That sends MIDI out to the phone, which is the wrong direction. Use plain Software Instrument tracks.
Good to know
The sound cuts in and out
That is the free trial ending after three minutes. The one-off $14.99 unlock gives you uninterrupted play. It is a single payment, not a subscription.
It says "No MIDI device connected"
The phone needs a MIDI link before anything shows up. See the MIDI Out tab. If your phone has no USB MIDI option, Honor and Huawei especially, use Bluetooth or a USB MIDI interface.
The MIDI notes are too high
That is ARGISH's own octave. Transpose down an octave or two on the receiving instrument.
