How do i Add a Program change with the Value 0 it won't let me go below 1
This occurs when the dedicated effect must be still active in style/midi file.
Leave the value at 1. In this case the effect is still in place and triggered, but you still hear a "dry" sound instead.
As Joe H says, believe me, the StyleMagic worth any cent you will pay for this.
Is a time saver software if you want to make quick and precise changes on the fly on you style or midi file, and many others besides that.
IMHO, I can't imagine if anyone's can survive on the onboard Style Creator without this piece of software.
If I do it on the keyboard Style Creator will it damage the keyboard???
Absolutely, NO!
The only can be damaged is the style you work on.
In that case, you must take a back-up of your style before you make any change on SYS/EX.
