Comment 18 for bug 197460

> When starting a Song Mixxx behaves like the Play button is being held down going back between play and pause at a fast rate.

I too run a Hercules, Control MP3 (via djconsole_legacy). This behavior occurred to me when I compiled a recent svn version that added Bheringer MIDI controller support -- it changed prefs for Input Controller to Behringer. I put it back to Evolution_Xsession or whatever it is, quit and restarted mixxx, back to full Herc functionality (minus LEDs of course).

(For some reason setting Input Controller to Hercules Control MP3 does not work.)
