well... i got my midi here, and some of my drum sample in wav, how do i use the midi to play with the drum sample without vst or soundfont?
You need some type of sampler, either a hardware or software based setup.

I'm sure hardware will add up in cash quite quickly so look into software.
Sonar offers Cyclone which is quite nice. You import each WAV file into the "sections" of the grid and assign a MIDI value to each section. When you use a keyboard or any MIDI hardware to trigger the software VSTi, it should play each sound.

Other than Cyclone, I don't know of any other samplers. TBH, I hardly use Cyclone or other samplers.
