## What is Performance Clock?

PortaTempo is a performance clock and setlist manager built for musicians whose hands are already full. Instead of reaching over to nudge a tempo knob or button between songs, set your next BPM and let PortaTempo glide you there automatically - so both hands stay on the gear that's actually driving the room.

STAY LOCKED TOGETHER
• Sync tempo instantly with any Ableton Link-enabled app or device on your local network - DAWs, other Link apps, sequencers, and Link-enabled hardware like Eurorack modules - with no cables and no manual re-syncing
• Join or leave a Link session at any time without interrupting playback

CHANGE TEMPO, HANDS-FREE
• Move from one BPM to the next smoothly using linear, exponential, or logarithmic ramp curves
• Or make the change instantly - a hard cut from one tempo to another when that is what the moment calls for
• Set the ramp duration in seconds, beats, or bars, then keep both hands on your rig instead of stopping to adjust tempo by hand

BUILD YOUR SET
• Save your go-to tempos as Favorites for instant recall - or start from 16 built-in presets spanning Ambient to Speedcore (20-300 BPM)
• Build a full Setlist with a target tempo for every song, and let PortaTempo advance and ramp automatically as you move through the set
• Loop your Setlist to create a rhythmic tempo sway - swing between 75 and 80 BPM every 30 seconds for an evolving, hypnotic groove
• Get a local notification with a customizable advance warning before each scheduled tempo change, so you are never caught off guard

MAKE IT YOURS
• Customize the colors for current tempo, target tempo, and highlights to match your rig or your set
• Fine-tune the ramp glow effect with 7 sliders covering radius, intensity, pulse speed, movement, and fade timing, plus 5 animation styles to choose from
• Hit randomize to instantly reshuffle every glow parameter - or turn on auto-randomize to get a fresh look on every ramp

USE IT INSIDE YOUR DAW
• PortaTempo also ships as an AUv3 plugin, bringing the same tempo control directly into your favorite AUv3-compatible host

EVERYTHING YOU NEED, NOTHING YOU DON'T
• One purchase unlocks PortaTempo on iPhone, iPad, and as an AUv3 plugin
• No subscription - ever
• Family Sharing enabled, so your household can share one purchase
• Runs in the background so your clock keeps going while PortaTempo is out of view
