Waveform

I recommend this lecture on the roots of reggaeton music. Certainly electronic with emphasis on sampling. Fun music with a rich history. https://youtu.be/yLOXfSQ5Zao

another one ive heard a hadfull of recently--- Now and Xen Podcast... https://nowandxen.libsyn.com/ this is about microtonal and xenharmonic music, largely but not exclusively electronic.

There was a relatively recent kickstarter for a synthesizer that converts electricity from plants into music. I'm not advertising for them but it does fit the parameters of your search of technology and music.

There is a "Tell me what you like/you might like" suggestion software called Gnod. Free to use browser map of music.

Cymatics is the art created by visualizing the vibrations of music.

Should I post links?
