Team,
The Ketron SD1 comes with a total of 307 styles. Of these:
* 109 are FLASH re-writable styles and can be replaced ... with YOUR styles [stored even after power off]
* 68 can be stored in RAM (from HD)[lost after power off] PLUS
* a total of 999 can be accessed from the HD [always available on HD).
That's a lot of styles ... if you were to ask me!
