 When switching to stereo mode you can see the base address that is currently configured for the second SID chip, displayed in the status bar. If the base address for the second SID is not correctly set up and you start playing the tune, RAM may be corrupted and the program might even crash. So make sure to set it up correctly. To change the base address of the second SID chip, press CTRL + SHIFT + UPARROW (not the cursor up key, but the other up-arrow on the keyboard) to toggle between $D4xx, $D5xx, $DExx and $DFxx. In order to change the "​xx"​ part of those addresses, press CTRL + C= + UPARROW to toggle the low byte of the base adress in steps of $20 (00, 20, 40, 60, ...). When switching to stereo mode you can see the base address that is currently configured for the second SID chip, displayed in the status bar.

 The config (mono or stereo mode, and base address of SID #2) is saved as part of the worktune savefile, so you only need to do the stereo SID configuration once for each tune. (Note that if you made a tune in a version prior to the 2014-06-15 version which had stereo SID support enabled, your tune may actually be remembered as being in stereo SID mode even if you didn't explicitly enable that. Just toggle back to mono SID and save it again, and it will be remembered as such.) The config (mono or stereo mode, and base address of SID #2) is saved as part of the worktune savefile, so you only need to do the stereo SID configuration once for each tune.
