		PITCH: The pitch begins changing immediately to the new note’s pitch when

PORTAMENTO TIME	0–127	Sets the time over which one pitch glides to the next.

PATCH STRUCTURE

Parameter			Value				Description
TYPE							Determines how Tone 1 and 2, and Tone 3 and 4
(Structure Type 1&2, 3&4)			1–10				are connected.
TYPE 1			TYPE 2				* If Type 2–10 is selected, turning off one Tone will

TONE 2 (4) WG	TVF	TVA	TONE 2 (4) WG		TVF	TVA	The displayed symbols have the following mean-
							ings.

TYPE 3 TYPE 4 B: Booster, R: Ring Modulator

						to distort. This creates an effect similar to the dis-

TONE 1 (3) WG TVA		TVF			TONE 1 (3) WG TVA		TVF		[What is a Ring Modulator?]
									A Ring Modulator mathematically multiplies two

									monic overtones that were not present in either of

					TYPE 8				Since the difference in pitch between the two
TONE 1 (3) WG	TVF	TVA			TONE 1 (3) WG	TVF	TVA		Tones changes the overtone structure, an un-
									pitched “metallic” sound often results. Ring mod-
