That’s a strange sound ! In this episode the dulcimer strumming is done with the vibration motor, pulsed by the trigger output of the micro sequencer. It is motion controlled with a dimmer. The vibration motor moves back and forth, driven by a servo to be able to touch all three strings. The servo is also motion controlled with a dimmer and pulsed by the same micro sequencer (with only pulse 1 and 3 ON) and a latch. The sound signal from the pickup elements is amplified via the echo delay bit and sent to the synth speaker (done for a nicer sound) and it also triggers the MP3 player with a second synth speaker, loaded with many different short percussion sounds. 

Duration: 3 Hrs.
