Using on more than one track

If I use the mouse keyboard on more than one track, then Reason 3 see's the input, as in the green bar above the paino keys moves, but it doesnt play a sound back through my speakers...is this a configuration part on my end, or an issue with the software interfaces??
I am unable to make two synthesizer tracks, the first one plays, as in anything coming through the first synth plays, and if I set the second track to the first synth it plays, but otherwise, I am unable to have two synths.
This is kinda not cool, I'd imagine you would be able to have two different midi synths

Hi,

sorry, I don't know how to solve this -- it seems like an issue with the Reason setup though. Maybe you get more help in a Reason forum?

Please let us know here if you find out more about this issue.

Thanks,
Florian
