Re: Why FL 12 is clippin very easily?
In a lot of traditional, old fashioned, console-based studios, engineers would start out with all tracks around -18 dB.
This is with respect to ~16-32 track consoles of the 1990s, where full mixes were done.
If you think about it, every +6 dB is a doubling of volume, and every -6 dB is a halving of volume.
So if you have two tracks that both have full scale 100% amplitude peaks, both will need to be around -6 dB to prevent them from ever clipping when you mix them together.
So if you work it out mathematically, for say 16 tracks or more, you will need them each to be pretty low to ever prevent clipping unless you use compression or limiting or transient shapers.
As it turns out, however, for music, most of the time sounds don't add together linearly. What they taught us in sound engineering school was that two 100% amplitude sounds mixed together will often add up to an amount slightly less than 200% because of the nature of waveforms often having areas where they cancel each other out somewhat. But it's not guaranteed.
Anyways, I'd say try initial levels of -18 dBfs and turn up the volume of your amplifier. And as the tune progresses, start using some channel-based limiting/compression/transient shaping.
