at the top right corner of the LCD: for example, “OP 3”. This only applies to parameters which can be individually programmed for each operator, however, when parameters that affect all operators simultaneously are called (the LFO WAVE, SPEED and DELAY parameters, for example) the current operator display will disappear from the LCD and individual operators cannot be selected.

A1-A4: OPERATORlAMS ON-OFFIEG COPY, 1—4

Individually turns operators 1 through 4 ON or OFF. In many cases a voice will not require all operators in an algorithm. Operators that are not needed should be turned OFF while editing. Also, during the voice creation process, it is a good idea to start with all operators OFF and then turn them ON one at a time as you program and add them to the algorithm. The four digits immediately following the algorithm number on the upper display line represent the four operators, 1 through 4, in order from left to right. When an operator is ON a “1” appears in the corresponding position, and when an operator is OFF a “0” appears in the corresponding position. Each press on the A1 through A4 buttons alternately turns the corresponding operator ON and OFF.

When the AMPLITUDE MODULATION SENSITIVITY parameter is selected (A14), these switches are used to determine to which operators the sensitivity setting will apply.

When the EG COPY function is in use these switches are used to select the operator to which the data from the currently selected operator will be copied. The parameters which can be copied are those of ENVELOPE GENERATOR and KEYBOARD SCALING.

A5: ALGORITHM

Permits selection of any of the 8 available algorithms. The desired algorithm number is selected using either the DATA ENTRY control or switches.

A6: FEEDBACK

Feedback can be applied to one operator in each algorithm. Pressing this switch permits setting the amount (level) of feedback which will be applied.

The feedback level range is from 0 to 7. At 0 feedback is OFF, and at 7 maximum feedback is applied.

Data is entered via the DATA ENTRY control or switches.

A7: LFO WAVE

Permits selection of the low frequency oscillator waveform. The available waveforms are SAW UP (a rising sawtooth waveform), SQUARE, TRIANGLE, and S/HOLD (sample and hold).

These waveforms are selected using the DATA ENTRY control or switches.
