In which I demonstrate the awesome sound power that is the EG&G PARC 124A lock-in amplifier when used for #willitmusic. This research instrument is a crown jewel of making music with test equipment, as it has all the parts that make an analog synth - VCA, multimode filter, oscillator. I have covered lock-in amplifiers before, but this one truly is the best so far. It can do tiny microsounds, glassy pings, throbbing basslines and process a TR-606 into a monster.
