MD900

DIV

Sets beats (quarter note) per synchronous measure:

1=4 QN, ½=2 QN, ¼=1 QN, 1/8=½ QN, 1/16=¼ QN, 1/32=1/8 QN

NOTE

Sets the factor how many LFO periods per synchronous clock:

•

Triplet 3x

•

Regular 2x

•

Dotted 1x

•

*Mod* Factor is controlled by modulation
(0-32% Dotted, 33-66% Regular,67-100% Triplet)

PANEL

LFO panel operation is done in the same way, only the DIV and
NOTE parameters cannot be controlled from the panel.

The selection of the waveform is done with the encoder

WAVE.

By pressing the focus button, the corresponding LFO can be
selected in the touch display.
