Y8950 is a sound chip
, produced in 1984. This model was used in MSX-Audio cartridge for MSX
personal computer.
This chip was introduced in three cardridge models:
Other software which makes use of the ADPCM sampler. E.g. Trax Player by NOP (a program to play songs (samples) directly from disk, while loading).
Actually, probably all Compile software, that supports FM-PAC also supports MSX Audio
Software, which requires the 256 kB of sample RAM

Software Support
Y-8950 is supported by almost all software which contains music composed in SoundTracker, Moonblaster, Oracle, Super Music Editor or Magic Music Module Combi, etc. All these editors support the ADPCM sample unit. Some support the keyboard.Other software which makes use of the ADPCM sampler. E.g. Trax Player by NOP (a program to play songs (samples) directly from disk, while loading).
