"The rich square wave of the CS-10 can sound somewhat like a bass clarinet sometimes. Also present here is a heavily Small Stoned Juno-6 with the filter all the way open for some sharp string machine-like sounds. The second, higher pitched lead and background noises, whispers and chirps are all courtesy of the CS-10 on the remaining tracks."
