Fast beat building
Open straight into pads, sequencer, mixer, FX, and presets. Factory kits and starter patterns give you a real rhythm before the idea cools off.
A 12-voice drum workstation
for iPhone, iPad, Mac, and AUv3.
Build fast, shape the groove by hand,
bounce sounds into new layers,
and export the loop when it locks.

TEMPO-1 is available for iPhone, iPad, Mac, and AUv3 hosts. The latest update expands step editing with velocity, probability, micro-timing, and ratchets, making it easier to shape accents, ghost notes, fills, and groove directly in the sequencer.
FX routing now works more like a track-based drum machine too: each voice can carry its own effect routing while master effects stay available for the full mix. TEMPO-1 and VA-1 Synth are also available together as a $24.99 USD App Store bundle, saving about $10 compared with buying both separately.
The full demo is hosted on YouTube so the high-definition video stays fast to stream and easy to share.
TEMPO-1 keeps the important drum-machine surfaces close: pads, step editing, kit shaping, mixer moves, MIDI control, and export. It is built for momentum first, with enough depth to finish the idea outside the sketch.
Open straight into pads, sequencer, mixer, FX, and presets. Factory kits and starter patterns give you a real rhythm before the idea cools off.
Shape patterns with per-step velocity, probability, micro-timing, ratchets, swing, BPM, pattern length, and visible step-page controls for quick variation.
Choose modeled and sample-based sounds, import your own WAV files, bounce a voice to sample, or bring an exported loop back onto a pad.
Map performance controls with MIDI learn, trigger voices from hardware, and run TEMPO-1 as an AUv3 extension in supported hosts.
Move ideas out cleanly with current-loop WAV export, current-pattern MIDI export, live WAV capture, and preset-bank import/export.
Open the complete TEMPO-1 PDF manual for pads, sequencing, kits, sampling, MIDI, AUv3, export, and preset-bank workflows.

Keep the core rhythm decisions in reach while you build: choose the page, set the working length, shape velocity, and keep tempo changes visible without leaving the grid.
Move through longer patterns without losing the beat grid.
Start tight, then open the pattern when the groove asks for more room.
Shape selected hits with velocity, probability, micro-timing, and ratchets.
Keep timing controls visible while the sequencer stays in focus.
Save alternate ideas and variations without rebuilding the kit.
The phone version keeps the same rhythm-first surfaces close: pads, voice controls, sequencer movement, FX, and routing.

PresetsTEMPO-1 combines modeled voices, bundled samples, user sample import, and voice bounce-to-sample. Capture or export a loop as WAV, load it back onto a pad, and build new layers on top.

TEMPO-1 is available now worldwide on the App Store. Watch the official demo, download the app, or keep the support and manual links handy for setup.
