Sound Design With the Halogen Spark Core
The Halogen Spark core is the starting point for most sounds in Halogen FM. Pressing the global Spark button produces a new patch, and each parameter can be randomised globally or individually, which makes it easy to generate variations you would not have programmed by hand.
The Timbre knob moves the tone from softer to bolder and more aggressive. The Modulation knob adds dynamic movement to the right and a more refined tone to the left. Turning the envelope controls to the right gives smooth pads, while turning them to the left produces more percussive, plucking sounds.
The developer describes the synth as inspired by a lesser-known branch of Japanese FM synthesis, and the two operators are built with identical features, so both can be shaped in the same way.
