So, this is proof not too many read the articles at the at the main page at Illmuzik, but anyway not too many people know Fl studio's hidden wave editor thats inside, whenever you open a sample hold ctrl+e and it will open, but it wont on empty channels, but this is something that's got some bugs to work out and I am sure pretty soon there'll be another release to fix it, although you can record with this editor, but it is more for smaller recordings like "eh yo" or "keep it funky" so you can record but use at your risk.... better yet, if haven't upgraded to producer edition that has the wave editor I suggest you go to
www.goldwave.com and get their free software, you can use this to record your vocals, and you'll have way more editing options than the fl wave editor.
Ps. just to let you know, the mic up top underneath the piano\keyboard icon, if this is what you're looking at, so you wont be confused - its representing the metronome, not a mic
