Hi there… You can use an FX chain on the kick track:
KeyTracker → LFO → Hydra
The keytracker reset the LFO.
Use a custom LFO envelope and set it to “one shot”.
Then either use the destination of the LFO to sidechain or add an Hydra device so you can use multiple places to sidechain.
That’s the method I used to use and it works alright but eventually I bought Duck from Devious Machines to keep things easy and quick, there’s also Kickstart 2 and some others.
