ClockBridge
Read full descriptionHide full description
AUM can send MIDI clock, but it can't follow one. ClockBridge closes that gap. Load ClockBridge in AUM as a MIDI processor, route your hardware's MIDI into it and turn on Link. Your groovebox or sequencer now sets the tempo, and pressing play on it starts AUM straight away, on the hardware's downbeat. Stop stops it. It's one button. The ring tells you what's happening: grey while it waits for clock, yellow once it has locked on, red if the clock goes away. Pull the cable mid-song and the tempo holds and the music keeps going. • Follows tempo changes as you turn the knob • Starts AUM on the hardware's downbeat instead of at the next bar • Steady timing even when the host delivers clock in audio-buffer steps • Timing offset in milliseconds, to line up with your hardware's latency • Sync can be mapped to a hardware button in the host • Light enough to load in every project ClockBridge uses Ableton Link, so the tempo is shared with every Link-enabled app on your iPad and your local network.

Verdict
The clearest difference is update cadence: ClockBridge at every 6 days against KNOCK's every 39 months. ClockBridge also leads on price ($3.99 vs $9.99). KNOCK's advantage is iOS requirement (12.0 vs 17.0). On ads, in-app purchases and device support there is nothing between them.
