That’s a really good feature request and I’ve added this to the task board:
There are already built-in parameter saving, but I honestly haven’t played around with it. I usually use Sample and Hold objects that save the state of the knob.
I’ll take a look into the built-in parameters and make sure the Believotron objects work well with the presets and get back to you.
We’re still working on displaying parameters to the OLEDs. We got it working and it was smooth enough, but then none of the upstream patches would compile because the OLED code took up too much space. We’re working on a hardware solution right now and will be shipping hardware updates to anyone who bought a beta after 2017-10-01.
