Are there any plugins out (or that are being worked on) that have filter sweep that can be set up in different ways? Something similar to the Electro-Harmonix bass micro-synth?
Go look for the remaincalm “mud” plugin in the unstable section. I designed that to do a bunch of different frequency sweeps with minimal mucking about with knobs - check the presets for some examples. (unstable just means “not significantly tested” but it works great for me).
