F ruity Loops Patches are composed of maximum 5 sounds (1 sound per octave) and even sometimes only 1!!!!!!
So when you play notes, it's always the same in every octave but pitched up or down, makin the sound really unnatural and ugly.
Reason work the same way hardware samplers/PCM based modules do, same way VST's do or pro synths do : Every instrument you got and load up is composed of 1 or more recording for evey note (sometime recorded with velocity) to be really close of the natural instrument.
For synthesizers, there is no sampling cuz a synthesizer is an engine that create is own waves, is own sounds. FL synths aren't that bad, but they sound thin and and weak.
Reason Subtractor for example, is an emulation of how classic analog synths calculate and produce sounds.
Take Rob Papen LinnPlug VST for example : this VST is a product that 5 programmers and engineer worked on for a year, only this VST!!! It sounds excellent!! Because it's professionnal, made by professionnal for professionnal. Fruity Loops is a basic program to get into music making, but you should already upgrade to something better. If you wait, when you,ll try something else, you will say ''shit all the time i lost....''. the interface of Fruity Loop is completely different from every other product on the market, like every cheap and toy software. Try Logic Audio, Cakewalk, Sonar, Cubase, Pro Tool, Digital Perfomer, Cool Edit, Nuendo, Samplitude or any big name software and you'll find out your way quickly cuz they r build on approximately the same way : a good way to work.
Try it you got nothing to lose. that's my humble advice. But it's an advice from a guy who began to make music with Hip-Hop E-Jay lol!!!! Then I used Acid Pro and Fruity Loops, and I tried every other software from Arturia Storm, to Mixman Studio. I got a full collection of every software : More than 50, Approximately 200 VST/DX effects, approximately 50 VST Instruments, and more than 200 original Cds of sampling, refills, akai's, and so on.
When i found out reason 4 years ago, i said man wut am i doin with fruity loops (I know fruity as changed since then i tried it last month). So i only want you to have better toolsin your hands. Reason is for software loved as much as MPC for hardware in hip-hop.
