My coworker has bought the axoloti and we plan on making some kind of hardware synth with it. We figured it would be cool to do a digital analog hybrid, so I'll be making a VCF and probably an analog EG so that we only need a trig out from the axoloti.
My question is, should I be setting up some voltage buffers so I don't accidentally blast like 15 volts DC into the audio jack? I'm pretty new to synth DIY so I want to be as cautious as possible.
Thanks
