The Quilcom SIM-BP is a synth designed to simulate the sound of many different types of bagpipe.
It uses no samples, just synthesis methods. This means that while it may not sound as authentic as real sample sets you do have fine control over the timbre and behaviour of this class of capped reed instruments.
