Features

Software Support

The Y8950 is supported by almost all software that contains music composed in SoundTracker, (Moonblaster, Oracle, Super Music Editor or Magic Music Module Combi, etc.). All these editors support the ADPCM sample unit. Other software that makes use of the ADPCM sampler, such as Trax Player by NOP (a program to play songs (samples) directly from disk, while loading) also supports it.

The majority of games made by Compile on the MSX were MSX-AUDIO compatible, although they didn't use the ADPCM sampler portion of the sound chip.

History

Developed in 1984, the Y8950 was primarily targeted at the MSX home computer market, where it was used in MSX-AUDIO expansion cartridges. Three main models were produced:

• Philips NMS‑1205

• Toshiba HX‑MU900

• Panasonic FS‑CA1

The chip’s integration in the MSX-AUDIO standard provided better audio capabilities compared to other computers of that era.
