In fact, truth be known, I can barely compile a kernel to save myself. Sad but true. And whilst my lab is currently in a state of disarray, I am mainly a hardware person. Apart from a little bit of machine code on small micros, I couldn't cobble together "hello world" in a pink fit.

But I'm more familiar with slackware than anything else. I'm the kind of animal that dives in as root and damn the consequences. I never did get along with ubuntu for that reason. :(

This is apparently the only thing out there which will understand the FS. However it's totally made of unobtainium these days. I've been searching for it for months. The A4K would otherwise be perfect. Nice filters. 3 FX chains. Solid hardware. Perhaps a little too solid as it's big and weighs a ton. Best of all, I've got one right here right now. And it's fully tricked out. But if I can't talk to it, it's really just a boat anchor.

It was limited but I still managed to record albums, master and play live with it. Scary as that thought might seem. I liked the work-flow in fact. There were lots of trade-offs but apart from anything else, it's ISA and can't be pressed into service these days.

I'll still need networking and SAMBA though. And if it could do MIDI over Ether, it would be the ant's pants. Otherwise it would have to talk to a generic, (Read cheap Chinese made) USB MIDI interface.

Regardless of which it has to live in a 19" rack for gigging. I was thinking that perhaps I could find an old lap top with a broken screen for nix. Tear it apart and, as a friend of mine once put it. "Modify it beyond manufacturer's specification." This of course means it would be using a 5400RPM disk drive. Although perhaps with a little cable jockying, I could run a 3.5" drive in the box. It would be nice if I could get it to boot from FLASH but just as long as it's relatively physically quiet.

Most Mo-bo sound systems have a buffer which can't easily be tweaked. Therefore it may be necessary to use a PCI card of some kind. And I need to figure this out before I even start thinking about nailing a test-bed to a piece of wood.

When I say hardware based, I mean that the wave-table engine is based in hardware rather than software. So that the software need only control the hardware. This is a far more robust solution. But it would still have to meet the above specs (Or something close) and I would still need to be able to edit/tweak and play it as a synth. It also means that the CPU wouldn't have to be as fast. Probably even a PIII would suffice. (Were it not for the GUI.) Has anyone done this kind of thing to any great effect?

I have been thinking for a long time how nice it would be to build a linux based synth with an actual front panel. This is a long term goal but it would be rather cool. Design the front panel fairly generically and shove the board out on the net. Then people could chose the synth system they want to build, whack the front panel onto a Mo-bo and build a proper rack synth. Only a synth that can be upgraded and tweaked.
