  1. Hey! u are right! they are slo! I forgot about that!(maybe I'll just have another row of motorfaders (sliders) instead of 8 rotary encoders!!) LO, btw, how are your panasonics going? do they work well? Was it much hassle to set them up? is the lack of touch sensitivity a hassle? how many controls are there on your box? from Steve..... have fun with your midi stuff! ;D
  2. Hi, yes, you definately need 20.000 Mhz crystals, no more, no less. Ring a few of your local suppliers, even some electronic appliance component trade stores sell them, you may save yourself having to make an order for just 2 crystals, and you don't have to wait for the mail either! :) You had better tell Mike first actually, I suppose he should send you the right parts for free. good luck with your midi adventures! .......Steve
  3. I will consider swapping a SID chip for some kool parts if someone can offer me something kool enough! :-/ bye from Steve
  4. LO, wow that's so cheap! Jkerman, I may not be able to drill the holes, unless I can borrow a dremel or similar drill (I drilled over 600 holes with a pistol drill and I'm never going to do that again! .....RSI holding clumsy drill!) if u r still interested, loonatron@yahoo.com
  5. just make sure you are following the "how to program" page on Thorsten's site 'to the T', cos I thought I was, and didn't realise that I had skipped a few steps (configuration of IC prog) cos the instructions had been updated since I last used IC prog. It's usually something simple that has been overlooked that halts these projects!
  6. wow! things are really moving along! and Thorsten has hit over 500 posts!
  7. Basta, some motorfaders have an extra resistor track for use on automated analogue mixing consoles, where the resistor forms part of the signal path. But this creates the problem where the electrical noise from the motor gets into the signal. That's why VCA's are usually used, where a control voltage is referenced from the slider position, which contols the Voltage Controlled Amplifier for that slider. I think this is how the automation system knows the position of the fader too. cos on some consoles you can turn the VCA's on and off. well at least I think I know what I'm talking about, someone correct me if I'm wrong! bye from Steve ;D
  8. Maybe we could have a different thread for swapping parts that we can't get easily in our local area.... e.g. I would consider making PCB's for people if they could send me a motorfader or two!! or I could post crystals or BC337's for smaller parts! btw I don't have a credit card and I find it hard to order without one! what do people think? btw, Thorsten, I'll make pcb's for you for free 'cos you da man!
  9. Hi, Â I don't know about the company you mentioned, and folding, but an alternative could be this....

I think a large folded box would be expensive to post, but it's up to you. I hope this makes sense! (I hope my dia gram dosen't mess up too!) bye from Steve ;) Â
  10. ;D ;D ;D ;D ;D ;D ;D ;D ;) ;) ;) ;) ;) ;) ;) ;) Thanks for all that effort! Its very kind of you to put such step by step configuration on the forum for me! I hope it didn't take too long! I just loaded the file in, without problems! now I gotta go set up my gear to try it out! thanks again, you legend! from Steve ::) ::) :)
  11. Just wondering... if someone has had success, could you copy the text in the buffer after you load the hex into ic-prog and email it to me at loonatron@yahoo.com? but only if you have built a working midimerger using ic prog. thanks heaps........Steve C :P
  12. Hi Quenzer, I bought a PCB from oakley sound systems over the net, for a midi to CV device. Hopefully I'll get a chance to build it before I go back to college. There was stuff on the old forum about cv to midi, there may even be some stuff on Thorsten's website somewhere. (remember that the pots on a midi controller are just voltage references, converted to digital in the PIC ADC) As for automation of old gear, now that would take heaps of work!!!! I doubt many people have ever tried it! (it has only been in the last 10 years that half decent automation has been around you know! someone I know had to sue an otherwise well respected electronics company a few years ago for supplying a dodgy automation system for a large analogue desk!) good luck with your analogue adventures! from Steve ;) btw, my stereo has an automated volume knob! :P (sort of!)

    Wow Thorsten! :o I could sit and look for hours! ;D one question, when are you going to run out of space for all your gear? ;) People must be surprised when they come over to your house and see all your inventions! .................Steve C :)
  14. Umm........I'm pretty sure all Thorsten's circuits specify pot values........make sure you buy linear pots for midi controllers.....there's more info in the FAQ page if you need it ;) dunno about the encoders. I don't know much about motorfaders, except that there are a lot of types! :-/ bye from Steve C ;D
  15. Hi, I ran 2 midibox 64's off a single 500ma plugpack for a while (no motorfaders) but you would have to find the specificatons for maximum current draw of the motorfaders to calculate which size plugpack/transformer you need. A circuit only draws as much current as it needs to.... example -an led with a series resistor will only draw a few milliamps from a 6v torch battery, but an electric motor with a load can draw many more amps from the very same battery. that's as much as I can help as I'm not familiar with the motorfader option..... from Steve C
  16. Well I poked around with my multimeter a bit, and found that data gets through the optocouplers, I see the voltage on the input pins of the PIC fluctuate by 0.25 to 0.3 volts when a fairly busy midi bitstream is coming in. But the output of the PIC dosen't change at all, it always stays at 3.8volts with respect to ground. ?????????????????????????????????????????????????? bye from Steve (pulls another cheezy face!) :P
  17. Well I tried programming the PIC again, only this time I turned "code protect off". I tried programming both with and without "swap bytes?" and the PIC supposedly verified ok, but when I tried it in the midimerger, no midi data passed through the merger at all. (both times) any ideas? thanks.............Steve :o
  18. Hi,   I was wondering if anyone can tell me what I'm doing wrong.... I have programmed heaps of Pic's, but for some reason I can't program the midimerger firmware into a PIC16F874 or PIC16F877! I'm sure there is something simple and obvious that I've forgotten, as I had this same problem ages ago, but I can't remember what the solution was!  I'm using IC Prog, and it asks me "do you want to swap bytes?" when I try to load the firmware into the buffer window. It dosen't matter whether I select Yes or No, I still get programming errors!   Any help appreciated, I hope everyone is having fun with their midiboxes!  bye p.s. I put this message on the design message board as well by mistake! oops! :-X he he lotsa cheesy faces  ;D  8)  ;)
