Ironically it was my interest in music for the Game Boy that brought me to this site.
I've been making music on the Game Boy for a couple of years. It was Pocket Music for the GBA that made me use Music on the PS1 and then I was drawn here
In the chiptune community, Pocket Music for the GBA is considered a whole lot worse than Pocket Music on the GBC. Simply because the sample quality is so bad. At least on the GBC the instruments on the two melody channels are not samples, so there's no horrible noise. I used Pocket Music for a while then gave it to my brother, who had a play around with it a couple of times before giving up on it as well.
Actually although Pocket Music on the GBC has 5 channels, the game boy only has 4. The wave channel can be made to play two samples at the same time.
I'm fairly sure nobody needed to know that, but since the topic was Game Boy oriented I felt the need to stick my nose in ;-)
After 2 years of using LSDJ to make music on the Game Boy, I've only just got round to using Pocket Music GBC. I'm liking it, but I have a question. Does anyone know of a way to take the edge off of the noise of the samples? A hardware solution that I could use live, like a noise gate or something? I'm afraid I have little knowledge of musical hardware

All help greatly appreciated.
