The "non black" wire is more likely the "+".
To be sure take some multimeter (basic models can be found in any
hardware - electronics store for quite nothing) and check.
You might find that the measured voltage is higher than the rated
voltage : nothing wrong, your supply is not regulated, and being
unloaded voltage rises. A regulated PSU gives a constant voltage
relatively independant of the load, but they're not so common, most of
the time the regulation part is located in the synth, sound module,
effect box etc...
