OTS is one touch setting. The PSR2000 has four buttons dedicated to style-appropriate voice changes. The preset styles have preset One Touch Settings for each style. With user styles, you can custom design each one touch setting and save that with the style. The CVP209 styles that I shared with the group all have one touch settings created by Yamaha for each specific style. Even though the PSR2000 has about 30 less voices than the CVP209, the CVP209 styles and OTSs seem to translate well onto the PSR2000. I think that if a style voice or OTS voice doesn't exist on the lower-level keyboard, it defaults to a similar voice.

So it's really fantastic to buy a new keyboard, and then all the sudden receive the freebie of 120 professional styles with custom OTSs. It would take a long time to create OTSs for 120 styles. It would probably be a group project that would never get done.
