Thanks for all the reply.
Thanks, I will try it.
I've lowered my DAW's option and settings to lower the extensive lag-time, now it seems workable. Yeah, I do need a new machine in order to dive deeper into world of music productions. I am currently financing for one, so wish me luck hahaha.
Btw, a question to FruityLoops users: I can't figure out why FruityLoops isn't recording what I play into the PianoRoll. Instead, it just records random notes into the step-sequencer. Is it because of the above hardware problems?
