While looking for information about making a keyboard matrix scanner I bumped into this. Someone might find it interesting.

And some MIDI info
http://www.hinton-instruments.co.uk/reference/midi/protocol/index.htm






Open thread for random interesting links

Droff ... omg. Ol' Hal is WAY over me noggin' with that bit. It were interesting though as back in 'the day', I'd picked up a working Rhodes Chroma for $250 Canadian. Surprised Smile (I can't remember what I did with the unit / who I sold / traded it to.)
There were some interesting techniques used in that little bugger as well. It's a bummer that that machine were a big part of what had killed Arp. Sad It was a GREAT sounding machine. (Ooopsie daisies ... am I crossing the machine's development memory mistakenly, with Arp's Quadra?)

And the Motorola 6809. I LOVED that chip, for as little of it as I had understood, in the 80's / 90's. It'd been the heart of my first ever computer (The Radio Scrap Color Computer) as well as the hearts (2 of them) of the Ensoniq Mirage. (And 10 of them, if I recall correctly, along with a 68000 - powering the first Fairlight CMI.)

And TJ ... the Arduino ... again, I've a faint wish, that I'd gone with that processor instead of the PIC. Ah well. It'd prolly have been just as steep a learning curve initially, as I'm currently facing, ANYways! Very Happy Laughing
A GREAT collection of info. into 1 place though. I'm sure at least 1 person here, will appreciate that. Smile

yeah, the arduino is a cool piece of kit. The community is really big and most of the code is available for free. I think the pic uses C language? The arduino IDE also uses a code similar to C. I never really understood much of the whole coding business but with copy/paste you can go a long way.
