I just got sampletank xl 2.0. I want to be able to sequence it into Pro Tools LE. I'm trying to play sounds from sampletank with my midi keyboard but nothing is happening. I have an audio track and midi track ready to go and when I press keys on my midi keyboard I see a signal in the midi track but no sound is playing in the audio track. How do I successfully get my midi keyboard to play sounds from sampletank and then sequence it in Pro Tools?
