FREE (basic) music production software

My 11 year old, 750 mhZ, desktop computer with FL Studio4 on it is at home, and I've been really antsy to make tracks with the crappy/amazing Yamaha keyboard I found on the street about a month ago.

Thus far I've been just recording layers/individual sounds and editing them on Audacity, which works and is fun, but is incredibly time consuming - if only because of how long it takes to match up and sync everything. My question, then, is whether there's any free programs with a sort of FL studio or Garage band type format where I can essentially sequence samples. I don't need effects, presets, plug-ins, or anything like that, just some sort of easy to use way of laying down and editing a track.

Thanks.

http://reaper.fm is uncrippled to try until you buy

reaper has some good midi functions, could be worth looking into

Uncrippled?

Anyhow, thanks.

Oooh, it would also be very nice if I could time stretch (i.e. make edits) somehow.

i haven't worked with it deeply but iirc it does do reasonably good timestretching

uncrippled as in it's 100% functional even though you haven't bought a license yet.

yeah anything basic you'd want to do reaper can probably handle it. it's got a great all-in-one workflow around sampling / editing / midi sequencing etc. it's all i use, everything else feels clunky in comparison.

I really enjoy using Renoise, which is also 100% functional as a demo as far as I know.

I believe you can time stretch with it, if you add in a free app from the archive.

renoise demo does not let you render to wav/mp3 but there are ways around it (soundflower on the mac, for example)
it's definitely more geared towards tracking, though.
