Hi !
I regularly read this forum, but it's my first post. I'm a french amateur musician,and, as you know, french people are very bad with foreign languages, so...
I own a G8. It's my first workstation, and I really love it. I composed some songs *only* with it (no computer and other gear), except, of course, a microphone

(having a phantom power supply is a GREAT function !!!)
These are french songs, really more amateur than amadeusvk's or johns's work, but, as it is another style of music, maybe it coud give other ideas of what can be done with the FG.
As it is first a "personal pleasure", and so not necessary very interesting to listen, I noticed some specific points for each song:
1- La falaise: Nothing (but I love the guitar sound used for the introduction)
2- Hors jeu: I used a multisample -imported from Akai- during at about 2:30 (the solist voice)
3- Vers le soleil: I used up to 5 audio tracks on the last chorus. No slowdown in the FG use.
4- Une étincelle: the longer, but probably not the more interesting song. You can pass it
5- Peur du noir: I wanted to do a song to highlight EP songs, because I love them. Missed, we remember electric guitar sounds. I also use a "phone effect" (with build-in MFX) at 2:30
6- Toujours et à jamais: the drum track is recorder in audio mode from an arranger keyboard
7- La machine: The more "electronic" song. But it is very far from techno... See the instrumental case at 2:10
8- La lettre: I like this song, but there is nothing special to say.
9- Une seconde: It's the first song I recorded, with my first workstation, so, of course, for me, it has a special taste. The "clock" sound is a WAV file, with a very light time-streaching
