Hey there,
Is it possible to modify or substitute that boring image when starting SONAR Plat. I'm really tired of it & want to create my own that would lift my creative spirits every time I started up SPLAT. Thinking of a sub in the depths & a blip scope image ...
Thanks in advance,
Dan

Yes there is.  The file you're after is called "Splash.dib" and it's located in "C:\Program Files\Cakewalk\SONAR Platinum".  Make sure you backup the original before editing it.  When you edit it, keep the dimensions that same. 

After editing, export the file as a Windows BMP file named "Splash.BMP".  Then rename to give an extension of "dib" so the file name becomes "Splash.dib". Put the file back in "C:\Program Files\Cakewalk\SONAR Platinum" and you're done.  I've actually done this myself (I colourised the squares at the bottom)

Of course the program path above assumes a 64bit version of Sonar.

Thanks mate,
 
I'll give it a go.
 
Dan
