FREE TO START, PRO FOR UNLIMITED WORKFLOWS
PunchKit is free to download. Connecting, browsing, previewing, playing, sharing, renaming, deleting, restoring backups, and using existing files remain available without limits.
The free tier includes:
- Up to three stored takes
- One saved kit and one complete kit upload
- Three successful sample writes
- One stem separation
- One bank backup, one project backup, and one complete-device backup
One optional Lifetime Pro purchase removes these workflow limits. There is no subscription, and PunchKit Pro supports Apple Family Sharing. People who first downloaded PunchKit before version 1.3 receive Lifetime Pro automatically.
LOCAL-FIRST BY DESIGN
PunchKit has no account, advertising, analytics, or tracking system. Audio and EP content stay under your control. Issue reports are sent only when you choose, with optional redacted diagnostics that exclude audio, samples, projects, and filenames.
PunchKit is built for sound design, performance, recording, kit creation, and dependable backup - so you can spend more time making music.

PunchKit 1.4 expands recording, processing, live performance, and connected EP sample management.
• Enable RECORD WITH FX to capture through the complete effect chain

• Stack Color and tempo-synced Motion effects in Direct, XY, Custom, or RAW layouts
• Use the redesigned cassette controls for monitoring, recording, playback, looping, Punch It, and full-screen tape performance
• Double-tap effect sliders to restore the active preset value
• Keep playback speed when switching presets and shape it with a centered logarithmic control
• Use compact, aligned effect controls across take editing, sample editing, and RAW mode
• Rearrange live EP pad assignments by dragging between pads, with confirmation before clearing an assignment or deleting its device sample
• Preview library samples by holding a row, select and review multiple samples before deletion, and search or refresh from the library toolbar
• Check available EP sample memory before uploads and show preparation, deletion, and refresh progress sooner
• Choose the MIDI channel used for pad-preview note messages
• Record from the built-in microphone or compatible USB audio, manage original and rendered take versions together, and follow live or saved-take tempo
