Yeah, maybe there is only one driver out there.. Strange... The laptop has one hardware serial port that can be configured as COM1 or COM2. When I configure it as COM1 the portman driver dosen't see the com port at all. When I configure it as COM2, the portman driver thinks it 'sees' COM1, but it never actually works (I get the 'portman hardware not detected' error messages. Oh well. the laptop was for free and the interface cost me $25. I only bought it to use editor software with my JX8P synth. Yeah, it would be interesting to see what driver version you are using, if it isn't too much trouble, Jidis, thanks!

Yes, its a little confusing until you see the picture, as there are a few 'almost right' ways that the diodes can be mounted! But once you see a pic, it all makes sense! (don't worry, you are not the only one to get confused by this!

The driver for the portman PC/S can't see my com port, even when I manually tell it which address and IRQ it is on. I know the serial port works, as I have read, erased, and reprogrammed a PIC on that port. The interface does work on a different computer. Does anyone have any suggestions, or know of where I might find an alternative driver? :-\ Many thanks from Steve

The Scenaria system is not good enough to use the way it is? (saves a lot of work!?)

Yes, they are engineered very nicely. I got to have a play with the faders on a LAWO mc²-series desk in 2003. The faders are soo smooooth. They spent a lot of time getting their motorfader driver algorithms just right. It is worth having a good look at the action of these faders!

Very nice mini-tutorial! Looks good.

Bugger. So you can get the rest of the parts you need for your midibox?

I have powered midibox projects off batteries with no probs before... See my posts in the tested crystal thread to see which crystals I used. (sorry if I missed something, I'm in a hurry and haven't read this whole thread... yeah I know its not good forum ettiquette... :P)

:-[ oops :-[ I don't see a solenoid coil either. I'm glad you guys picked that up!

7311239899 From an old automated MCI console. Motorfader circuit would need modification to handle the current. The driver chips may need to be replaced with higher current devices, as these faders use solenoids. The supply regulator would need upgrading but this is easy. Downside... There is only 10 of them on offer. And it may be a long time before you see any more of these on offer. and I'm not sure what the resistance value of these is.

I've been meaning to try that paper/toner transfer method, but haven't had the time. BTW another source for Press'n'Peel is Jaycar in Australia and NZ as well as altronics in Australia. (Not Allelectronics in USA)

I have no idea! I just use "press'n'peel" film. You just photocopy the pattern onto the film, then iron the pattern onto the board. Then etch. Quick and easy. But then the time consuming part is drilling all the holes! Better to buy from Mike or Smash. 8)

Nice website! I've never seen those fast motorpot knobs before!

Do you want me to get them for you? I'm in Australia! (But someone else has already bid on them! Someone from here? A bit of competition!) In the mean time I'll be thinking about that German bulk order!

7306515426 :) Maybe someone wants these? Very cheap!

Oh Crap! These large audio electronics/software companies really make it hard for people without lots of money. First crApple, now Avid/Digidesign. Really, really crappy >:( I wonder if manufacturers like Mackie will make firmware updates to work around digidesign's plans to shut them out?) on another note... Err... not quite... refer to the 9th post in this very thread... The LC protocol is really midi bandwidth hungry, I'm sorry.

look at the pink dots at the RH end of the DIN board http://www.ucapps.de/midibox_lc/midibox_lc_enc_ts.pdf They are the touch inputs. You simply take out the 10k resistors from the board and mount the 47k resistors instead.

That's a good idea, Roger, I don't know, why not just try it and see what happens... but why not investigate the method I already mentioned? It is much simpler...

Er... you can find good info on the tutorial LC thread, but it never got finished... :-[ But as long as you can read circuit diagrams, Thorsten's re-drawn diagrams make it really easy to construct an LC now! ;D www.ucapps.de/midibox_lc.html you can see the links to the diagrams on this page. Now the only hard bit is getting your firmware into the PIC. But there is heaps of help here on this forum ;) Maybe all the info is on the previously mentioned thread (can't remember)

Glad you found pics of Stav's board. I didin't notice that nice jogwheel until now! The board also has nice matrixing options right in front as well. OK, back to LC. Each of axel's LC's use a separate midiport. There is no daisy chaining of cores going on, as each LC is recognised as a separate device by the host software (Logic Audio). (Also makes it easier to deal with! But it also chews up 3 whole midiports! But this is unavoidable...) What software do you want to control? Logic? (the best for LC!)

Aother source of joysticks... cheap clones of analogue playstation controllers? (I haven't tried this, its just an idea)

reguarding 4)... look at www.ucapps.de/midibox_lc/midibox_lc_enc_ts.pdf to see how you can use a standard Din module for a touch sensor input, with a simple resistor modification. I'm not sure if you need to change something in the application code if you want to do this with DIN pins other than the standard touch sensor pins. Just open each relevant sections of the application code in MPlab IDE to read the notes TK has written within the application code to verify. Here is a diagram on connecting one of the available types of graphical LCD... www.ucapps.de/mbhp/mbhp_glcd0.pdf Once again you need to get into the application code in MPlab to enable graphic LCD before you turn the code into a .syx and load it into the PIC. Default setup is for character LCD. If you want some inspiration for new ideas, try to find a pic of Michael Stavrou's new control surface. (though I don't like the curved meter bridge) Another new concept is a control surface that is projected onto a flat white surface, that is scanned somehow (similar method as a touch screen?) so that you can touch buttons, sliders etc, and the laser projection updates the position of sliders, status of buttons, etc, as you touch them! Good luck with your thesis. ...Steve

Oh boy! you guys are way beyond the technical depth of dsp and programming that I can understand! (chuckle) I am so surprised that someone wants to go to the trouble to get that 80's sampler sound!

do a forum search "corona" or google it for a PCB pattern for a JDM clone that has a socket for your regular pic16f84. I actually used the corona layout as a guide to make my veroboard version of the JDM, with sockets for both 18pin PIC's and 40pin PIC's. (With modifications added later, as recommended by TK) BTW Jaycar in Australia has lots of cheapish kits for programming eeproms. Oatley electronics do too. I dunno what software you need though. ...Steve

my brother's friend found this... http://web.media.mit.edu/~ladyada/make/minty/index.html apparently it comes from www.hackaday.com This site may have some naughty hacks on it so browse at your own risk! I haven't looked at it properly yet, but I thought that some of you would probably want to take a look! One strange thing is that the PIC18LF452 microcontroller apparently runs at 20Mhz or 29.xxx MHz which I wouldn't have thought it would be able to do. See ya, from Steve
