Which launcher are you planning to use?

There is still a quantum attack against symmetric key crypto like AES, but it just reduces the effective key size by half. If you use long enough keys (256 bits) you’re still fine.

VCV rack is awesome, if not the easiest to start from scratch with. For those who haven’t heard of it, it’s basically a virtual modular analog synthesizer. You can build your own sound generating machines out of a huge selection of modules, including oscillators, filters, sequencers, etc. Some of the modules are based on real hardware modules that you can buy, but there’s a huge variety.

It’s fun to play around with, but if you’re new to modular synthesis then I recommend limiting your module selection to just the built-in ones to start because the full selection is pretty overwhelming if you don’t know a VFO from an ADSR evelope generator.
