The OPL4-ML is a single-chip, FM-enhanced wavetable synthesizer synthesizer
Machine that electronically generates and modifies sounds, frequently with the use of a digital computer, for use in the composition of electronic music and in live performance. designed for all PC audio platforms from add-in cards to motherboards, and all PC audio applications from games to desktop music.
The new chip integrates a "wavetable-sample" ROM and General MIDI A standard set of 128 sounds for MIDI sound cards and devices (synthesizers, sound modules, etc.). By assigning instruments to specific MIDI patch locations, General MIDI provides a standard way of communicating MIDI sound. processor with a wavetable synthesizer and an FM synthesizer on a single chip. The standard General MIDI interface allows games to directly access wavetable sound.
"The Yamaha OPL4-ML sound quality is a function both of the wave samples, made using Yamaha's own high-quality instruments, and our exclusive wavetable recovery and synthesis techniques," said Tim Lavelle, multimedia sales manager sales manager n → gerente m/f de ventas

"Bringing highest quality sound to the widest audience is our mission," said Bob Starr, general manager sales and marketing, YST YST Yukon Standard Time . "This new product meets that goal."
Fat Man Certification
The 1MB wavetable sample ROM inside the OPL4-ML contains the same sample set as the stand alone ROM which was evaluated and certified by Fat Labs in compatibility tests earlier this year. These tests are designed to ensure that systems will work in a musically balanced way with any General MIDI software known.
"Based on our tests of the OPL4 with 1MB ROM, we expect that systems containing the OPL4-ML will also be certified and recommended for General MIDI music," said The Fat Man George Allister Sanger.
The Fat Man is the biggest name in music for multimedia, and the Fat Seal is the most credible and valued endorsement in the industry.
The Yamaha OPL4-ML provides the same rich FM-enhanced wavetable sound as its predecessors in the OPL4 family. Powerdown mode and selectable voltages optimize this new chip for portables and desktop applications.
Easy Upgrade from Basic FM
System manufacturers can offer both standard and high-end audio High-end audio is a term used to describe equipment that is purported by the manufacturers to be the best, regardless of the price. Definition of 'high-end'
High-end audio with a single motherboard through a simple assembly option. The board is laid out for two audio chips. For basic Soundblaster FM applications, only the Yamaha OPL3-SA single chip audio device is used.
For General MIDI wavetable applications, the OPL4-ML is placed on the previously empty pad, and a Yamaha SA-1 audio CODEC (1) A hardware circuit that converts analog voice into PCM or ADPCM digital code and vice versa. The term may refer to only the A/D and D/A conversion, or it may include the compression technique for further reducing the signal (definition #2 below). See sampling and codec. replaces the pin-compatible OPL3-SA on the other pad. This upgrade option provides the system manufacturer with maximum flexibility and minimum effort.
The OPL4-ML is available in a slim, surface-mount, 100-pin SQFP See QFP. package, suitable for add-in cards, PCMCIA cards and motherboards.
Price and Availability
The OPL4-ML chip is offered in the $20 range in volume quantities. Engineering quantities can be available in November. Production quantities will ship in the first quarter of 1996.
