1. Internal DAC

The internal OPL3 and the ZV Port shares the internal DAC, which is very similar to the case

mentioned the previous section.

(i) either internal OPL3 or ZV port is active at a time and simultaneous use is not

possible.

(ii) which function the internal DAC is used for is determined by the SA3 control

register, index 02h, VZE bit.

2. OPL4-ML/ML2

The external DAC (YAC516) and the clock module (ex.MK1420 by Micro Clock) are

necessary for wave table upgrade.
