roginator Posted April 29, 2006 Report Posted April 29, 2006 Hi Im new here and Im in search for midi DIY or kit for first polyfonic digital synth ever made...RMI Computer Keyboard KCII.....I owe one and love itIts made organ manufacturer in early 70s......any idea here???I know that it can use 61 key trigger directly to Keys....where can I found that kind of project????D
jimhenry Posted April 29, 2006 Report Posted April 29, 2006 The MIDIIO128 project is the one to use for converting keyswitch closures to MIDI messages. You'll need a Core and 2 DIN boards for your 61 keys. It is probably easiest to add new contacts under the keys for the MIDIbox rather than trying to find a signal that you can use without upsetting the KCII unless you are pretty savvy about what is going on inside the KCII.
Davo Posted April 30, 2006 Report Posted April 30, 2006 http://www.vintagesynth.com/ doesn't have an entry for this beast. I'm curious how it sounds.
roginator Posted April 30, 2006 Author Report Posted April 30, 2006 Whell....how that sounds.... WIERD and GREAT....It use some kind of 8Bit DSP???? actualy sounds are made from layering waveforms wich are presets in box and can be loaded from punch cards....its sound gridy and warm at same time....realy fast envelopes and nice chorus and vibrato for strings....can emulate everything....I own PPG 2.3 system and sometimes it sounds fatter than PPG!!!!!cards looks like thisit has 8 polyphony and can be in dual mode...4 polyphonicno vcf here but I drive it thru modular vcf with envelope folower and thats a bomb...as far as I know its realy rare synth maybe 3-4 Europa.....and around 100 made of KC II...maybe less.....
roginator Posted April 30, 2006 Author Report Posted April 30, 2006 I just went thru Core and DIN Modules....Maybe somebody have this PCBs or populated boards for sale?????Im interested in that!!!!I WANT RMI TO SING MIDI!!!...I will read al about MIDIIO128 ...and ask what I dont understand!!!!
stryd_one Posted April 30, 2006 Report Posted April 30, 2006 Keep reading, all you search for is already documented. :D
jimhenry Posted April 30, 2006 Report Posted April 30, 2006 Maybe somebody have this PCBs or populated boards for sale?????Go to the DokuWIKI http://wiki.midibox.org/ via the button at the top of the Forum page. Look for the entry on where to get parts and kits. Building a core and a DIN and experimenting with them on the bench will teach you more in a week than you can learn with a year of reading. Be sure to include an LCD display, at least in your first project.
roginator Posted April 30, 2006 Author Report Posted April 30, 2006 WOW ..so many things to learn..but Im on good way to understand it all..
stryd_one Posted May 1, 2006 Report Posted May 1, 2006 It's kinda fun really :) Only, it eats up ALL your spare time if you let it... I always try to ;D
