I've noticed a tendency for eBay to do that... I think maybe one person lists an item and then another owner sees it and thinks "I might list mine now" or something... Anyway I'm obviously a worse eBayaholic than you cause I posted that last night in the Toys thread ;) heheheh

TK's implementation is able to do all that and more :)

Well You've basically got 3 choices as far as how to send the message: CC's - 7 bit. Fixed. It's in the spec. (N)RPN's - 14 bit. Again, fixed, in the spec. Slightly slower, of course. SysEx - Whatever you want. SLOW. Would defeat the purpose of fine bit depth by reducing frequency of changes to an unacceptable level. Trick is that the PIC has 10 bit converters onboard, so you'd have to use external AD if you wanted to use an analog pot/slider at full 14 bit resolution. You could always just drop the 4 least significant bits, 1024 steps ain't so bad... Maybe you could emulate the effect on your PC, take a few bars of your favourite song, and reduce the volume to say 90%, and then 89.9%, see if you can tell the difference ;) OK now put it behind a compressor and some fx and a PA style brickwall limiter and see if you can spot the difference... But if you just gotta gotta go digi, you've hinted that you don't want rotary controls but sliders. There are linear encoders, but you'd have to develop your own driver and I think they're hard to come by in the type you're after... You could write code to use two sliders as a coarse and fine control, which would probably be OK or maybe even better for onscreen positioning, but would be sucky for xfades. Or you could try a little gadget I've been working on if you want... You know what tank tracks look like (You know, those things that armoured vehicles have instead of tyres)? /------------------------------\ |o E| \------------------------------/ Basically you take a length of rubber, and you make a little conveyor belt, wrap it around a pin and an encoder, voila... Takes some creativity and tools and a lot of patience. Some hints: The axles, including (the one attached to) the encoder, need to be fixed at both ends. Bearings are your friends. If you used to skateboard grab an old set and reoil them. Cogs with teeth and matching teeth on the belt are best, otherwise the encoder will slip in an unpredictable manner. Or else you could employ a method similar to a belt drive turntable where the spindles have a lip which grips the belt. Another idea... some of us might remember a few weeks/months back talking about the position sensing LED matrix Which one of these ideas is best will depend upon the situation... Personally, I'd go 10 bit and use a slider. Anyone have any other ideas?

'Cause it's "Retro" and that's "cool" ;D Vintage warmth? ;) Crazy Russian Mafia are trafficking him drugs in shipping containers marked as SoundBlaster cards? Seriously though, that's a good link thanks man!

Hi 'Grinder :) Welcome aboard! I just thought that seeing as you're new I should mention that taking Jim's advice could be very beneficial to you... he's very well versed on these kind of things. I know it might be a let-down if your initial idea might be too difficult for the meantime, but it's much better to suffer a little disappointment now and wait a while until you have finished learning about the organ's electronics, than it would be to ignore Jim's advice and bust up such a special treasure :)

It's kinda fun really :) Only, it eats up ALL your spare time if you let it... I always try to ;D

That's mine ordered :) http://www.robotparts.com.au/speakjet.htm

I don't know, but the way it's rearranging lines on the screen, outside of their designated character posistions, looks like it might be a dud LCD... but a short circuit can make a device do strange things....

Keep reading, all you search for is already documented. :D

Hi :D Well OK... The instructions are complete, but to say they are well written would be a stretch - they do tend to be spread out and interspersed with other information. But that's the nature of such a project :) .... You will be OK, but it's important to understand that it's really up to you, not the documentation. You might have to read a lot more and surf around a lot more than you would like to, in order to find the information you need... But so long as you are prepared to do the hard work, you'll be fine :)

>:( Yeh Smash and while you're at it why not find Hoffa for us?

It means that how it is handled will be specific to your application because it isn't part of the recommended design. But this doesn't mean it won't work... In fact most of the controllers I've seen make the addressing work the same way, so it might just work 'out of the box' :) Just get the LCD and give it a go :)

Oh yeh I was just talking about the OP, with the encoder ring around... Though this might interest someone: http://cgi.ebay.com.au/CONTACTLESS-JOYSTICK_W0QQitemZ9719138665QQcategoryZ78827QQtcZphotoQQcmdZViewItem

Yep. It's application specific of course...

Like I said I'm already bidding on the last two... We'll have to battle it out :(

trackballs.... I'll buy two of them and you can buy one off me when youve got the cash man. Any other aussies want one?

Might I suggest the discussion be taken off-forum? No offense intended....

TK the unstoppable strikes again ;D

Mmmmm, braaaaiiins. Must....have.....braains.... Now, where's that zombie emoticon?

Damn, I didn't get the call I was expecting to wake me up, and I missed it :( Bidding on the last two now...And damn the price is going up fast :'(

That's right.

OK let me re-word what I said.... When I said "Programming PICs" I meant writing code for them, not flashing them. What's your problem with uploading firmware by MIDI? Seems to me to be far easier, scalable, blah blah blah... I dunno, it sounds like you are thinking about taking a much harder path (using the 4620) in order to make an inferior product. I think you're nuts ;) Edit: Staight answer to your question: Yes, there are lots of reasons not to use the 4620.
