If you’re into making music and find yourself with a lot of time on your hands now in these rather strange times, I recommend Surge which is free these days. I’ve used it on many of my tracks in the past, and you can get it here: https://surge-synthesizer.github.io/
Regardless of whether you make music or not you can also get VCV Rack, I can lose hours by twiddling around in it. It doesn’t require a DAW and is much cheapher (FREE) than hardware modular. Get it here: https://vcvrack.com/
Stay safe people!
