SynthBerry Piis the first prototype of an autonomous synthesizerbased on PDSynth. PDSynth is a toolkit for creating programmabledigital synthesizers made using the Pure Data visual developmentenvironment. To run PDSynth synthesis architectures a Raspberry Pimini computer was used. Eight slide potentiometers are connected tothe mini computer to create a control surface that makes it possibleto control PDSynth's architectures. SynthBerry Pi is, therefore, acompact standalone synthesizer capable of creating sounds by usingPure Data patches.
