I'm having a hard time getting my hookup correct.

I have an Ensoniq EPS-16 Plus I want to use as a master, and an Alesis Micron to use as a slave.

I cannot get the Micron to play, using the EPS-16 Plus keyboard. I can get the EPS to play using the Micron keyboard.

Help this MIDI dork out please!

Thanks, and I apologize if this is in the wrong forum.
