ok, I think the best thing we can do is start from the start.
So you're trying to start loops, that's all doable, but...
Can you tell me what you have, what Sequencer are you're using, what DAW, what keyboard you have, what audio/midi device you're using. What other software you have in the mix. Are you Mac/PC? What machine are you using?
You can control Spark with a keyboard you don't need the specific controller, but it is far better with the proper controller as you can only play drums with keys, there are far more controls on the dedicated hardware.
