Oh noooo no no, there is no way you can be into modular synths and be lazy! Some effort is required...!
No wonder you are scared hehe
Come on... you are capable of typing many words, listening to music and saying kind things about it all... not the actions of a lazy person!!
I have no nightmares no, it's not that hard, a little effort and you will also feel confident.
Let me be clear, an oscillator is a device that turns a DC signal into an AC signal - whooooop! Such a simple idea that causes so much confusion! The higher the input voltage the faster the capacitor charges and therefore the faster the release... i.e. the faster the oscillation between charge and discharge... yikes!! Is that it... well, yeah :)
All you need to do to be safe is think about the signal you are generating, is it in audio range? If yes, then, with suitable attenuation (either in the mixer itself or before the signal reaches the mixer e.g. output module), you can almost certainly connect it to your mixer!
I am sure there are folk who will challenge these ideas, but as a working definition it has never screwed me over :)
