A quick look at an x0xb0x being built by my work colleague SuperNick (Nick). It is a DIY analogue synthesiser based on the Roland TB-303, and this is an Adafruit-era build. Since this video was made, Nick has tested parts of the board using an audio-card oscilloscope and confirmed sawtooth and square-wave output. That does not mean the whole synthesiser was finished and working.

If we are lucky he’ll make me up some tunes to go with some of these videos. I sometimes think I am going crazy due to the same six songs, over and over and over and over. Stay tuned! 😄

The build later reached the fully assembled stage, but the completed unit had no sound. The later posts are linked below.
