Chip's Jack Machine
Retro Beats for New Heat
$4.99 · Designed for iPad. Not verified for macOS.
Launch price. 16 voices, four scenes, swing and WAV export — a hands-on drum machine that works entirely offline. Buy once; no subscription, no account, no ads.
Chip's Jack Machine is a pocket-sized classic house drum machine — 16 voices, a 16/32-step sequencer, and the hands-on knob-per-function workflow of the original hardware, with no menus to dig through.
Most of the kit is synthesized live rather than played back from a sample library, so every knob genuinely reshapes the sound instead of filtering a recording. A few voices are built from recordings where a real one simply sounded better.
FEATURES
• 16 voices — bass drum, snare, low/mid/hi tom, clap, closed and open hat, cowbell, rim shot, maracas, low/mid/high conga, claves, and cymbal.
• Per-voice TUNE, DECAY, TONE, SNAPPY, LEVEL, PAN and VERB — every one of them live.
• 4 scenes (A/B/C/D) with instant switching, copy and paste. Each scene keeps its own pattern, bar length, mute/solo state and knob settings.
• 8, 16 or 32-step patterns with swing.
• Step recording — arm RECORD and play the pads in.
• Load your own audio into any voice with SAMPLE.
• Low-latency audio engine built for playing, not just playback.
• Export a pattern as WAV, or export every voice separately as stems.
• Save and load projects as .house files and move them between your devices — the same format the whole Architect Series uses.
Runs on iPhone and iPad.
Buy it once and it's yours. No subscription, no account, no ads, no in-app purchases, and no network connection — the app works entirely offline, forever.
Part of the Time2Jack Architect Series.
