regarding Auto pan and LFO
there are MANY modules able to do what you are asking (of course I don’t remember the names)
many mixer too!
I can talk for nysthi modules:
nysthi::quadpanner can of course do stereo panning too of single source
is the Buchla 227e mixer emulation of single channel (included the LFO)
but being modular you can do any override you want !
the nysthi::4mix (and other)
have input that are stereo or mono, and bot can be “PAN animatable” using the PAN input, and increasing the VCA. the small display let you set the current offset if you want something all PAN left (for example) to be animated toward right
