I was pressed for time today, so I dived in to the Blofeld and pulled out a synth sound rather than doing anything terribly musical. Today I played with FM synthesis, which uses one audio signal to modulate the pitch of another, and I came up with a jazzy vibraphone/electric piano sound.
FM is a lot more complex and mathematical than analogue-style synthesis, but it’s an interesting tool, and it’s definitely well suited to metallic or bell-like sounds like this. The great thing about synthesising these sounds, instead of just using samples, is that you can sculpt the sound in realtime — this sound gets not just louder the harder you hit the keys, but brighter too, by increasing the amount of FM based on the key velocity.
