How do I side-chain in Loopy Pro?
Loopy Pro doesn't route a side-chain to AUv3 effects at the time of writing (November 2026). The workaround is a plug-in that links its own instances: one instance on the source sends audio, and another receives it. Woodpressor has its own side-chain send and receive, and OneMove Vocal Console has Key Link. We make OneMove Vocal Console.
Feed the rider the music with Key Link
- On the music (a backing-track channel, or a bus with the loops), add OneMove Vocal Console and choose the chain preset Key Link: Send Music. It passes the audio through unchanged. Its Key Link status reads SENDING.
- On the vocal, add a second OneMove Vocal Console with your vocal chain.
- On the vocal instance, open Expert ▸ Ride ▸ Key Link and set Music From to Link A. The status reads LINKED.
Use another letter, B to H, for a second pair. If two instances send on one letter, the panel shows 2 SENDERS!
Questions
Does Key Link add latency?
The sending instance runs its Live zero-latency path, which reports 1.3 ms to the host.
Is Key Link unique?
No. Other iPad plug-ins link their own instances too. Key Link sends audio between instances of OneMove Vocal Console.
What happens without a side-chain?
Ride follows the vocal alone, which still evens out a performance.
