hey guys, is there a tutorial about tone switch smwre?

There probably is, but I can't find it or it's been nuked from Smithy Anvil or something. To place a tone change in EOF, seek to where you want the tone to change, use "Track>Rocksmith>Tone change>Add" (or just press CTRL+SHIFT+T) and type a name. Do this at each point the tone should switch. If you refer to a tone more than once, make sure you type the name exactly the same. When you're done, you can review the tone changes with "Track>Rocksmith>Tone change list". If those all look correct, go to "Track>Rocksmith>Tone change>Names" and this will help you make sure you didn't make a typo on any of the tones (ie. if you called one "Distortion" and the other "distortion", they will show up as two separate entries and you could rename one of them here to make it the exact same name as the other). When that looks good, you can select one of the tones in the list and make it the default tone (the one in effect at the beginning of the song). This should be all you need to do in EOF for the tones, the rest of it is in the toolkit.

thx! seems easy enough, will try it tomorrow

works like a charm :) thx buddy

How many tone switches are allowed during a song? Is there a limit? per track/instrument?And how many tones can be included in a .psarc? Including lead/bass/rhythm.. Is there a limit?

I don't know if there is a limit to how many switches per arrangement can be made but you can only load 4 different tones per arrangement.

Data can take either approx. 2 or 4 billion switches, not sure where RS limits are.
