MIDI functions

I bought a Alesis Q25 and I am running it on Cubase LE 5. how do I get it to work??? because I cant hear the audio when I am playing it. do I have to change the settings for it to play??? I need help in this. If you can help I will surely appreciate it.

What are you trying to play with the Q25, how have you set it up in Cubase. Do you see any midi activity.

Just to make sure: The Q25 is a midi keyboard and as such sends midi, not audio. You have to route the midi from the q25 to a source than can produce sounds from it, like a software synth. Try creating an instrument track with HalionOne in it and setting the Q25 as its input.
