One for me please, in in the UK. Thanks S

I'd like one CFAH2004ATMIJP (the Blue one)to the UK please. S

Did anyone do anything with a POKEY? Got one from a job lot of old computers including C64s and from what I have heard I like very much. So if anyone knows anything or can save me re-inventing the wheel, it would be appreciated. S

Thanks Thorsten! Didn't have any caps at all on the DOuts, so stuffed the leads of a radial 100uF into the header of the first Dout, switched on and success! Even better when I called the Girlfriend in to press some keys (I can't reach the keyboard) and took the cap out, it all works perfectly! And it still does! Have no idea what that was as everything was working OK with the other boards, but it seems pushing the leads of the capacitor into the plug made something happen. Thanks again. SD

Thanks for your input, it is appreciated. Decided just to use program change messages on an unused channel and embed them in the file. If anyone has any better ideas, please feel free to chip in! Once again many thanks SD

OK, this one has really got me pulling my hair out. Am just coming to the end of my 5th Core board, it’s going to be another MIDIO128, DIns are OK, LCD OK, problem is that the LEDs connected to the DOuts are always lit. By swapping with known working boards, I know that: The DOuts themselves are good, they work with 3 other boards. The PIC is good, it works with 3 other core boards. The LCD is good. The sequence of events is normally this, power up, the LEDs light (not flash), the LCD displays normal messages, yet the LEDs remain lit. Sometimes though, on power up the LEDs light, then go out, the MIOS copyright message is displayed and the Core locks up. It works fine with just DIns and fine when the DOuts are disconnected. The problem is somewhere on the core, yet all voltages seem OK, as do the solder joints and there are no obvious shorts anywhere. Have read the forum, tried the usual things (checked, double checked for shorts, solder blobs etc) but still no joy. Has anyone got any ideas at all? Because I am really stumped. Thanks in advance. SD

Thanks for the reply. I think you may have misunderstood. I am using a real pipe organ, its a MIDIO128 but only using the DOUTs! There are no DINs or AINs, only a MIDI In and 128 DOUTs. What I am after is for the commands above to activate the relevent DOUT pin. Anyone? Thanks once again. SD

Hello all This question is about swell shutters on a real pipe organ. The instrument was originally controlled by a paper roll player and I am using MIDIIO128 to control the notes and stops, that’s all fine, it plays and changes rank. But it would be really good if everything could be controlled via MIDI. The shutter is a six step affair, so there are six stages to get a get a fully open shutter. My idea is to use Channel Volume, B0 07 xx, to open and close the shutters. So what I would like to do is to have six pins on the DOUT respond to say: B0 07 02 B0 07 08 B0 07 0F B0 07 20 B0 07 40 B0 07 7F And only these values, these are just example values and if at all possible, they could be changed via the MIDIIO128.ini file just as the other pins are. From what I can tell, the B0 xx function only responds to either 00 or 7F. Anyone got any ideas? Thanks and regards SD

Thanks for the offer George, more importantly, thanks for the info. Didn't know about these things and I have a few projects on the go at the moment so this is EXACTLY what I am looking for. Have got one off ebay and am awaiting its delivery. Thanks and regards S

AT89C2051 for me? Hello everyone, hopefully this is posted in the right place, but can anyone program a couple of these for me? I don't really want to go to the bother of buying/building a programmer just for two chips. I will of course pay for any costs and supply the chips. I am in the UK Thanks in advance S

Thats right to MIDIfy your pedals you'll need: 1 core 1 DIN (you could build that on stripboard) Load the MIDIO128 application. In terms of a smaller sized project, you don't have to fit all the components to the core in this case, take a look at the schematics and see what is actually used. If you decide against an LCD you can leave out a whole bunch of components. SD

Hello all Have you looked at this? http://www2.netdoor.com/~rlang/xylotron/xylotron.htm Have had dealings with Tom Scarff before, he is a great guy, think all his projects are now Public Domain, so drop him a polite email and he is bound to respond with PCB layouts. (He has done many MIDI projects but NOT the above!) Hope thats of use to someone. SD

Thanks for the reply Moebius, Thats just what I thought but was wondering if anyone had experience of doing this already? I'll let you know how I got on and what the settings etc are. SD

On a similair note, does anyone know if other PICs, in particular 16F84 and a 16C73 (maybe a 16F73?) can be programmed with the JDM and ICPROG? If so, how? Just been looking at a few interesting MIDI projects on the web which use these PICs and wondering if I can use the JDM for 'em. Thanks all SD

Thanks for the reply Raphael. Yes thats it, thinking about it, it kind of makes sense. So just in case anyone else gets confused about this: If the MIDI_MERGE option is anything other than DISABLED, do not have the MIDIBox In connected to the same PC/device as the output or you'll get the loop effect. In answer to your question though, Win 98 and MIDI - OX, but don't suppose that matters now! Thanks again SD
