I have the EA-1 an the EA-1s output goes from
its MIDI out, not the thru.
The thru just passes whatever comes in,
without changing it.
What you might need is a Phil Rees midi merge
box, so you can have multiple outputs going
into one input. see
http://www.philrees.co.uk available through roguemusic.com .. They
are fairly affordable... 100-220$ pretty much.
As far as the out vs. thru, I think that's
pretty normal, isn't it? My other synth
behaves the same way...
