What is the difference between .sndr and .txw?

Description: The SNDR file extension is used for older 8-bits mono sound format which was used in old Sounder program.; The TXW file format is associated with the Yamaha TX16W, a digital sampling keyboard produced in the late 1980s. These TXW files contain audio data that is specifically formatted for use with the TX16W sampler. Essentially, a TXW file stores a sample or a collection of samples, including their associated parameters such as loop points, velocity layers, and other settings that are necessary for the sampler to correctly playback the sounds. The format is proprietary to Yamaha.
