Novice Logic Express user has Midi setup problems

Question

Hi, folks. I'm a novice Logic Express 7 user (I used a much earlier version as a sequencing package a very long time ago). I've just installed Logic Express 7 on my Mac OS X and connected my Technics PCM Digital Piano PX 107 to the Mac via a MIDIsport UNO midi interface. There's some stuff happening (and not happening) that I don't understand yet.
Firstly, I can see on the transport window that midi in and out are both registering events, but I am getting a wierd echo of very low notes coming back through the keyboard speakers, making it impossible to make any sense of what I am playing.
Secondly, if I turn the volume off on the digital piano, I can't hear anything at all, even when midi events are being registered.
Thirdly, I don't appear to be able to record anything. Once I click record, the midi seems to stop functioning altogether.
Lastly, my midi metronome click comes back through my keyboard speakers as a very low note.
Should I have my keyboard volume turned up at all? (My guess is I shouldn't, but I can't hear anything at all at the moment if I turn it down). And can anyone help me with these perplexing problems. All contributions very gratefully received, thanks.

I think you need to figure out how to turn off local playback on your keyboard. You are probably hearing the sound from your keyboard as you are playing, plus the sound that the keyboard plays when Logic is sending midi notes.
There appears to be another problem that your midi is being transposed down in Logic. That would explain the low "echo" and low metronome click.
All the sounds are being made by your keyboard--that's why you can't hear anything when you turn it down. What is it that you are trying to do? Do you want to record midi and have that play back through your keyboard, or do you want to just use your keyboard as a controller for Logic's sounds?
