ON-DEVICE / FOUR STEMS
Pull the track
apart.
Keep it private.
Separate a take into vocals, drums, bass and other. After an optional one-time model download, processing runs locally on your iPhone or iPad — your recording is not uploaded.
LIVE / PUNCH IT
Perform first.
Bake when
it hits.
Four pages — Color, Motion, Space and Custom. Perform stackable color, tempo-synced motion and long modulated reverbs with Direct and XY controls, capture beat-synced loops on the cassette, then bake the result into a take, pad sample, or library import only when you are ready. Original and rendered versions stay together.
PREVIEWPERFORMLOOPBAKENON-DESTRUCTIVE
- COLOR + MOTION + SPACE
Stackable color, tempo-synced motion and a dedicated Space page — reverb, dub, granulator, tape echo, shimmer, infinite and more.
- DIRECT + XY
Play parameters directly, or route one or more effects — including Space — through the XY pad.
- 12-SLOT CUSTOM PAGE
Mix any Color, Motion and Space effects into a 12-slot Custom page with a six-effect-wide editor tray.
- BEAT-SYNCED LOOPER
Capture half- to eight-bar loops from live input using MIDI clock, detected audio or tap tempo, then scratch them at ½×, 1× or 2× tape speed.
- PREVIEW → BAKE
Live preview first. Bake later into recordings, pad samples, or imported library sounds.
- ORIGINALS SAFE
Original takes stay intact when you bake a processed copy.

/WHY PUNCHKIT
Why PunchKit is the
EP companion to use.
PunchKit is a dedicated iPhone and iPad companion for Teenage Engineering EP-133 K.O. II, EP-1320 and EP-40. It covers the full workflow — kit building, sample management, recording, stem separation, live effects and backup — in one app, with no computer, no account and no cloud processing.
COVERAGE
Built only for the EP family
EP-133 K.O. II, EP-1320 and EP-40 support in one app. Projects, pads, samples and memory state are read straight from the connected device.
KITS
Kit building without a computer
Assemble 12-pad kits from your own audio on iPhone or iPad and send them to the device. No desktop transfer app in the loop.
STEMS
On-device stem separation
Split a recording into four stems locally on your iPhone or iPad, then reuse the parts as samples. Nothing is uploaded for processing.
TAPE + FX
Recording with Punch It effects
Record USB or device audio, perform stackable tape, vinyl, chip, crush, filter, EQ and dynamics effects live, then bake takes without touching the original.
BACKUP
Real backups you can restore
Snapshot projects and samples, export a recording together with its project as one folder, and restore when a session goes sideways.
PRIVACY
Local-first, no accounts
No sign-up, no analytics or tracking system. Audio, samples and projects stay on your device and in your own iCloud.
Independent app — not affiliated with or endorsed by Teenage Engineering.

are saying.

Best KO companion out there
“This is the best companion app for the KO II I've found, by far (at any price). Truly incredible stuff. No latency, super flexible, and super easy to use.”
Phenomenal companion app
“On par (or better) than what I would expect an official EP companion app to be, from functionality to design. This opens up so much functionality that I was previously using my laptop for, but in a device that's already in my pocket.”
Must have for the EP series
“The app I've been wishing for since I got my KO II. Manage your samples on the go, record to tape, apply effects, and much more. My favourite feature is the kit builder, makes it so easy to create custom kits from your own samples without having to use a computer.”
Must have app
“Amazing app with good looking UI. Manage your samples and project without touching your computer. Since the EP devices have so little inboard memory this is a must have tool for always having full access to all your projects and samples on the go.”
Game changer
“This app changed my music making life. It cut out like 3 steps to my process. Do not hesitate to download.”
Essential for EP
“Just get it now. You need this if you have any of the EP boxes.”
