The YMF724 was made by Yamaha and mostly used inside different Computers of the 90s aswell as some PCI Soundcards like the Yamaha Waveforce WF192G. It’s also known as the DS-1 and as for sound synthesis, it supports OPL3 aswell as Wavetable Synthesis. The YMF724 was actually the first of the YMF7×4 Cards, which stands for XG Tone Generation and legacy support for older DOS Applications.

The name that is actually printed on the chip is YMF724F-V. It was later superseded by the YMF744.
