Hi Bebob,
what kind of styles did you download?
Only factory styles (Psr9000/2000, CVP209, etc) and styles made by third party companies will have OTS. All other home made styles and/or converted styles usually don't have OTS.
In order to have the OTS on your board lets say from the Psr2000, you have to load the style into the flash memory and select download with OTS. The disadvantage though is that you only have enough memory left for about 2 more styles. In order to save more you have to delete the ones you don't want first.
If you use the Disk Direct function, OTS will NOT load. A flaw in the OS?!
That's the only way.
Sorry.
Hope this Helps.
Eric
