If you wish to confirm whether CSDS has located the plug-in, bring up the CSDS music player, goto the 'Controls' tab, and look in the lower right corner.
What version of the chronotron plug-in are you using? CSDS is only configured to use 'Chronotron I' and 'Chronotron II' plug-in.
Most CSDS users who use Winamp use the 'PaceMaker' plug-in, as this plug-in allows for pitch changes too. CSDS should work with any version of the 'PaceMaker' plug-in. If you decide to get the 'PaceMaker' plug-in, please register it, or CSDS may appear to hang because PaceMaker may bring up a reminder message box (e.g., "please register") underneath CSDS. If this happens, just press the 'Enter' key to clear the message box, and CSDS will regain control.
