The BBDD is a hybrid percussive instrument that uses bucket brigade delay to create analogue Karplus Strong style synthesis. It features a fully analog signal path along with a digital 32 step sequencer with per step parameter automation of pitch, tempo and filter cutoff. I built the system for my engineering technology thesis project. In many ways this is still a prototype, but I’m looking forward to pushing the concept further in the future!
