This may be tricky, since you are not recording a song part while playing perse. I have a Korg with sounds I used in FLStudio 5, what I did was in Fruity Loops, I went into the program files (should be found in here: go to your C drive, click into the program files, then select the Image Line folder, which is the FL folder, when you get there, click on the data file and in that data file click on the User file, then right click inside the User file which should give you a drop down, select create New Folder, when you creat the New Folder it should be highlited for you to rename it, then rename either Samples or whatever suites your fancy.) used Acid to record the sound in a Wav. or Midi file, what i did was played and held down the middle C of each sound I wanted untill it decayed completely, once it's recorded, save it in the newly created sample file through the same path way i mentioned, when you open FL Studio and in the SBrowser at the bottom is the User folder, where it will have the sample folder with your recorded samlples you can use in FL. i have combinations, layered sounds, simulated B3s, pianos, certain runs and riffs all recorded from my Korg that I use in my FL Studio 5
I hop this helps, if this is not what you need let me know.
