Ian Stanley spoke on the theme of sound emulation. He featured the ARM-powered Robertsonics/SparkFun WAV Trigger board, and took us step-by-step through the process of writing a driver program for it on the Raspberry Pi using Doctor Wimp. He also demonstrated some Moog synthesizer sound samples on the WAV Trigger board using MIDI from the Pi, and then he demonstrated some vintage synthesizer emulations using a PC running Windows XP.
