I’ve been reading about his parallel-port MIDI adapter project at http://littlebluerodent.tripod.com/MIDI/Interface.htm and I was wondering if he ever got it working - it’d be perfect for a project I’m scheming up (I’d like to build a homebrew sequencer/workstation out of a little SBC I have.) His email as listed on his site is dead, and it says the other good way to contact him is via the comments on the BeBits page for his SqueekySynth program - but BeBits doesn’t seem to have a facility to register a new account!
Anybody know how to get in touch with him?
I’ve already built something similar with Haiku, a pc, some wood for the case and a cannibalized yamaha keyboard. I would suggest, if you just needed a midi interface to buy a usb2midi adapter for a few euro since they are supported by Haiku and probably have better performance than a parallel port adapter, in any case it will cost less in terms of time and money than building your own circuit.
I already have USB-to-MIDI adapters; I’m looking into this because I’d like to add MIDI capability to a Z80 kit SBC that has only a parallel and serial port for I/O (and I need the serial port for a terminal.)
Interested to hear more about your project, though 
This was nothing serious really, just a fun project, i’ve made it with a pianist friend…the aim was to look at how Haiku was ready to work as synthetiser. It was 3-4 years ago, and at the time we ended up with a dual boot haiku + linux.
Actually i would like to build for myself a digital pc-based effect, something like a netbook put into a case with analog controls such as switches and other things you normally have on musician effects. But just to don’t go out of topic i’ve opened another thread :
