The PSP (Pocket Sound Performer) by Berlin-based artist Niklas Roy, is a mini 6-bit synthesizer that has a lineout for amplification. The type of music it creates is called “hi-score” and it’s built with a few resistors as a digital to analog converter and a single transister as an amplifier. The six LEDs (seen in the video) as connected straight to the 6-bi digital output. Roy also uses dismantled PS2 joysticks for controllers so that it would be handheld
