Does Sonar Plat come with a signal/test tone generator?  Or can anyone recommend a freeware vst version?  I normally use Reapers ReaSynth plug in at my studio for bass drops, but on my laptop I do not have reaper installed.  Any advice is appreciated!!
 
(I have tried dimension pro, but did not yield good results.  I have not yet tried rapture)
 
 

Audacity has a tone generator. You can export / import them as WAV-files - if this helps.
I don't think that there will be any vst-plugin.

Cool, I'll give it a shot.  The standalone generator I downloaded did a good job, but I did not see any option to export.  Thank you

may want to try z3ta+
here is a free tone generator plug-in https://www.meldaproduction.com/MOscillator

I forgot that zeta came with platinum!  I loved using that for x2 and x3.  For some reason I only had Dimension Pro and Rapture installed.  I purchased platinum, so do I just download the additional content from the command center?

Expand the SONAR Platinum item to access the rest of the installers. Z3ta+ is part of the Platinum Instrument Collection.
