If you have a chance to sound check the best compressor settings could vary dependent on the space and the PA and the pattern and style and what drugs the audience have imbibed.
But appreciate that’s a mad copy paste over all your live patterns every set.
As long as you’re happy with the sound at home and it’s not all in the red a decent FOH should have their own processing chain and knowledge of the room/system to dynamically caress your sound into a best fit.
I don’t think there is a ‘one setting fits all’ scenario. But first things first I think your mix is your first and probably more important consideration. Making sure that your patterns have a balanced mix, meaning all elements of the track have their relative volumes set just right, and the overall mix being not too high and not too low, as well as keeping the mix consistent between different patterns is more important. Once you’re confident about your mix then some gentle compression to ‘glue’ the mix together is all you need. Of course, the compressor can also act as an effect, so if you’re going for a more ‘pumped up’ sound, then your compressor settings can be more exagerrated. There are many ways to set the compressor, but assuming you’re using it as a ‘master bus’ compressor, I would go for long attack, short release, ratio of 4:1 and set threshold for about 2db of gain reduction. If you’re really worried about not blowing peoples ears out when playing live I would consider an additional limiter, something like the RNLA, Alesis Micro Compressor, EH Platform etc…
Make sure to engage the HPF SC as well for live uses.
And, IIRC (haven’t owned a Rytm in a while), you can parameter lock it in the fx track sequencer as well. I do this on OT. Great for animating the compression even more for a fully mastered sound.
