Here's a program a made tonight, after work. My wife and our 5 month old son Caspar are sleeping in the other room and I was 'banging' out this track with the program I made. I didn't want to wake them up (obviously) so I had to think creatively.
This is the track:

And this is the instrument I made....

What I did is I downloaded some samples from the web which were really grainy and long and had all sorts of hiss, pops and crap in them. I tried cleaning them up, but that just didn't work out really well. So what I did is I chopped off the tail and only used the short attack portion of the sound (the old Roland D50 trick, when sampling memory was really expansive)...
To make the 'body' of the sound I also sampled a softened square wave with a little oscillator sync from my Novation Nova: this will sound sweet and metallic at the same time. I made 1 second samples of those and looped them (I think I could make them really, really, really short if I wanted too)...The file is now about 900kbytes but I think if I worked really economically I could do it in like 100kb or even less. (< hey! idea for a competition?)
I took like 4 or 5 different attack samples that each sounded a little different (this is also the way these soundbox' sound, they always sound a little toy like) and spread those on top of the looped multisample from the NOVA.
I added a filter with a lot of resonance (I think it was two peak filter or something) for that metallic 'twang'. The filter is modulated by velocity and by keytrack. When you play the mod wheel a sweet amount of vibrato kicks in (modulation of the pitch)....
Enjoy! I hope you like it. And please let me know what you think of it.
