If U render a track out of FL studio, Please look at your buffer. If U got an ASIO driver, there should be no problem. If you are using a standard driver.. It could be a problem with the M1... so go to general options and than audio and look if U can select ASIO.
Somtimes, I just put some pre cut samples in my beats... That's where cool edit comes in. Then the whole shitload into kontakt vst and just banging on my midi keyboard checking what's gonna be. Kinda like working with a asr 10
You can get a good free vst from luxonix, www.luxonix.com, with a good compressor etc., usually, i lightly compress my kick, then put korg MDX(fx vst) software on it, that piece will do the limiting. No clipping here!
