Ben,

Isn't the 300 mA rating the max current output rating of the power supply? 
The actual load (current drawn) would be determined by the input 
impedence/resistance of the keyboard which would, in this instance be 50 mA. 
So long as the voltage is correct the device utilizing a lower demand that 
the power supply can provide should work fine.  Now if the keyboard demands 
a higher load than the power supply utilizes, then you'd have problems.

In my opinion the power supply should work quite well without the keyboard 
going up in a puff of smoke so long as the voltage (9V) is correct.

Or perhaps I should have stayed awake in engineering school.

What was that expolsion I just heard?

:-)

Dick
