Here's a few observations or things that may be of interest.
The "save enter" button becomes very important.
If you adjust the volumne setting within a style, you save it by entering "save/enter" , pressing "save style" (F2?) and confirming by pressing F9.
If you adjust global settings, press "save enter" button and press F3 for Power on set up. The keyboard takes snap shots and saves them , all under the "save enter" button !
Also ...most of the styles on the 2nd or 3 pages of the category, were born on the X1 keyboard. All of the X1 styles carried over to the SD1plus, need volumne levels raised within each part of the style.
Make your adjustments by selecting the style, press F5 for "arrange view", you will now see the individual parts next to all the Function Buttons (F1 - F10) .. press the part and use the value plus button to increase volumne levels... After raising the volumnes.. press save/enter !
