Vortex Sound Research

hi all,

i'm not really a synth expert, so i figured you guys might be able to help me out. i have a minilogue and it seems to... not be in tune when i boot it up. like, i'd wait for it to finish tuning, then i'd open a blank, default patch, and play two C's, 3 octaves apart, and it'd sound almost a semitone off pitch. it seems to get better if i let the thing sit for a little bit or if i reboot it.

i've heard of tuning instability being a thing with analogue gear, but is it usually this pronounced? my sub phatty has no such issues.

thanks!
