Roland MC-909 Patch Edit Wave, Pitch, FXM Frequency Cross Modulation, Parameter Value Description

Patch Edit

Wave

These parameters select the PCM waveform that is to form the basis of the tone, and apply effects to the waveform.

Parameter	Range	Explanation
Wave Group	INT, SRX, PRES,	Group of the waveform upon which the tone is to be based
	USER, CARD	INT: Waveforms stored in internal memory
		SRX: Waveforms stored in a wave expansion board
		PRES: Preset sample waveforms
		USER: User sample waveforms
		CARD: Card sample waveforms
		* SRX can be selected only if a wave expansion board is installed.
Wave No. L/MONO	0 (OFF)–693	Waveform upon which the tone is to be based
Wave No. R		On the MC-909 you can specify a separate waveform for the L and R channels.
		* If you want to use the same waveform for the L and R channels, set the R channel to 0 (OFF).	Mode
Wave Gain	-6, 0, +6, +12 dB	Waveform gain (amplitude)
		The value will change in steps of 6 dB (decibels). An increase of 6 dB will double the gain. If you	Patch/Sample
		want to use the booster to distort the sound, it is effective to set this to the maximum.
FXM (Frequency Cross Modulation)
FMX creates a complex overtone structure by using a specific waveform to frequency-modulate the selected waveform. This is suitable for cre-
ating extreme sounds or sound effects.
FXM SW	OFF, ON	Selects whether FMX will be used (ON) or not (OFF)
(Wave FXM Switch)
FXM Color	1–4	Selects how FXM will apply frequency modulation.
(Wave FXM Color)		Increasing this value will produce a rougher sound. Decreasing this value will produce a more
		metallic sound.
FXM Depth	0–16	Depth of frequency modulation applied by FXM
(Wave FXM Depth)

Pitch

These parameters specify the pitch of the waveform, and how your keyboard playing dynamics will affect the pitch envelope (change in pitch

over time).

Parameter	Value	Description
Patch Coarse Tune #	-48– +48	Pitch of the entire patch
		Specifies the pitch in semitone steps over a range of +/-4 octaves.
Patch Fine Tune #	-50– +50	Pitch of the entire patch
		Adjusts the pitch in one-cent steps (1/100th of a semitone) over a range of 1/2 semitone upward or
		downward.
Tone Coarse Tune	-48– +48	Pitch of the tone
		Adjusts the pitch in semitone steps over a range of +/-4 octaves.
Tone Fine Tune	-50– +50	Pitch of the tone
		Adjusts the pitch in one-cent steps (1/100th of a semitone) over a range of 1/2 semitone upward or
		downward.
Rnd Pitch Depth	0–1200	Range of random pitch change that occurs each time a pad is pressed
(Tone Random Pitch		Set this to 0 if you do not want the pitch to change randomly. This value is set in units of one cent (1/
Depth)		100th of a semitone).
