i dont think i ever use the same kit with a different pattern
stems from a million yrs of MnM use
where even then often i’d load a random kit to the same pattern and see/hear the result
(never had this sort of vol jump on the MnM)
i guess i’ll have to really analyze the different kits the patterns are referencing.
This is most likely due to the multiple different gain-stages and level-controls. Filters, overdrive, and effects levels all contribute to the output. It can get crazy!
Applying an LFO to AMP has startled me more than once!
There’s no hard and fast advice to avoid such wild amplitude swings, but it makes sense to keep all volume/amp levels to a standard value according to your recording setup.
Leave the master volume fader alone, but work with the tracks’ levels to “get the balance right,” as Depeche Mode says.
So, no, there’s no issue with your sound-settings, per se; it’s just the nature of the synth.
EDIT: Parameters that may cause overload or clipping:
What I decided to do Today is to place a “1st” trig condition note on the pattern that you are changing to (the one where the volume spikes) and parameter lock things like ‘vol’ or maybe totally close the filter (LPF) on that trig. Do this on the offending track of course, find out which one(s) is/are causing the issue.
