Wave
These parameters select the PCM waveform that is to form the basis of the rhythm tone, and apply effects to the waveform.
Parameter Value
Wave Group INT, SRX, PRES,
USER, CARD
Wave No. L/MONO 0 (OFF)–693
Wave No. R
Wave Gain -6, 0, +6, +12 dB
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.

Description
Group of the waveform upon which the rhythm tone is to be based
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.
Waveform upon which the tone is to be based
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).
Waveform gain (amplitude)
The value will change in steps of 6 dB (decibels). An increase of 6 dB will double the gain. If you
want to use the booster to distort the sound, it is effective to set this to the maximum.
Selects whether FXM will be used (ON) or not (OFF)
Selects how FXM will apply frequency modulation.
Increasing this value will produce a rougher sound. Decreasing this value will produce a more
metallic sound.
