where from?? (just interested, thats all! I'm getting some off Ian!)

I hope not!! I can see it though.... zillions of questions aimed at Thorsten, on how to make it work! (I'm glad that man takes holidays a lot! ;)) maybe I shoulda keept my mouth :oshut :-X ;) but I can see Jack's idea working! bye, Steve

... I don't know about that, sorry but I do know this... you can save 'setups' on a midibox 64 (snapshot button) and save them to bankstick, then if you had the '64 in snap mode, the values will not change, until you move the knob past the saved position. But this (in my opinion) is still not as nice as an encoder setup (all controls respond instantly, and you don't have to reload a snapshot all the time... it gets tedious!!)(though it is nice to know where your absolute positions are on a real pot!) So, could someone please clear up the bits I couldn't explain?? (rotary encoder compatability) Dr Bunsen, have you seen Ian's posts on his bulk encoder order? .... Steve

Hey, well if you are getting the F0 00 00 7E 40 00 01 F7 message over sysex, it sounds like you have successfully installed the bootstrap loader! (that 0000h thing is a bit of a worry, though) Check that you have set all the configuration settings as on the 'How to prog' ucapps.de page. BTW, where did you get your bits from?? I think they have all the right parts at jaycar, for the programmer... if not, then Dick Smith? Go to the MIOS page (link near the top right, when you first open the ucapps site), then go to the link "bootstrap loader" just under the 'spec' subsection, read the instructions under "solution" heading, and it will all be a lot clearer to you!! basically, once you burn in the bootstrap loader, you then install mios1.2, (via sysex/midi ox) then install your application (from the mios download page) again, using sysex. BTW, which application are you building?? .... Steve oh yeah, I'm in sydney, in case you give up!

Hey, I've never seen a digital slider pot, but this concept on another forum could lead to a workable solution! (or maybe not!) actually, has anyone seen the digital calipers, used by metal machinists (like me, in my previous working life!)) to measure sizes? I wonder how they get their absolute position? (I know that the earlier models of 'mitutoyo' branded ones didn't have an absolute measurement, like an encoder... you had to set the zero reference with the zero button. hmm... opens up many ideas... but I don't have the resources to try them out! BTW, I'm going to try out my LC with a bigger ps 2morrow! maybe MF's will work better. bye.... Steve

Hi, sorry to butt in here, but do you sell motorfaders, Peter? Do you accept international money order/cheque? bye, from Steve sorry I speak no deutch!

oh yeah... welcome to the forum!! ;D

here goes.... you have a controller knob on a soft synth, controlling filter cut-off, for example. you have a project open on your pc, and you have spent ages tweaking a synth to get a sound you like. Now you close it, and start another project. All the knobs are in completely different positions. Now, you re-open the first one. The cutoff knob is in a completely different spot to the last project. Now you accidentally bump one of the knobs, but you're not sure which one.... the cutoff knob gets bumped, and the knob on screen moves to what the physical knob position, the sound completely changes.... see what a pain this is!! Soft takeover is great... it prevents this from happening, the on-screen knob will only move when you turn the physical knob just up to, and past the on-screen knob.... I don't know why all audio software dosen't include this as an option!! well I hope I didn't make that too long for you! (I tend to go off on a massive text mission!! ;))

hmmm... I think I must be getting close to 1000! (changing settings all the time!) does anyone know how to put a small delay in the program, to make the midi handler wait a little bit between sending a pitchbend (volume) message and the point in time where the fader has reached its last moved position? (my faders are sending midi before they have reached their last movement position) ... or is the motordriver moving them after they have finalised their correct position??? ....Steve

ok, something else is wrong as well.... I tried all those things. Does anyone know how many times you can write the application over sysex, before you 'wear out' the PIC?

Hey, I'm wondering how hard your motorfaders hit the bottom stops?? Mine hit pretty hard... panasonics at 6.5v anyone found a solution for this?? bye, from Steve

Hey everyone, I think I have found out why my LC isn't working very well.... I have been bending out the pins on the Panasonic motorfaders, to make them easier to solder. Now I have discovered that I am getting errors due to poor connection on the riveted joints on the pot connections.... this is probably caused by the mechanical stress, and stretching of the riveted joint, by bending the pins ....so don't do it, and you will stay happier than I am right now.... 8mf....stuffed! bugger! :'( on my midibox 64, I got heaps of jitter, and this was probably caused by the same thing!! (total of 73 stuffed pots!!) lucky I have 8 spare motorfaders (I bought 16 off basta73) oh well....

I'm a little reluctant to try the pic 16f877, as I don't think it runs the LC emu, but I would give it a go if someone can email me a logic environment just to test it out? (not ready to get into that environment just yet!) still havin probs... but it is usable...maybe I'm a bit too fussy. I get errors... approxiamately 2-3 over 50 faderbank switching cycles e.g. 22 midi volume becomes 23, and audio volume -47db may fluctuate between -50, and -43dB.... Can someone with a bit of mixing experience on the LC tell me if this is worth worrying about?? please answer me, so I can get some sleep at nights ;) instead of thinking for solutions...he he! I'll try to get someone with a cro to look at it soon. ...Steve edit... I'll try putting some ferrite suppressor beads on the ain input leads, and the power lead tomorrow, when I go to Jaycar. (Handy, it is across the road from college! I sneak over there when the teacher is not looking sometimes!!! ;D)

I think logic 6 comes with 2 versions... one for mac os9, one for mac osx. The mac os9 version is VST compatible, the osx uses the new audio units standard. (check with your emagic dealer though) logic 5 for pc is vst compatible (no version 6 for pc, bugger!) ...steve

there is a complete listing of which buttons to connect to which IC pins on this post.... http://www.midibox.org/cgi-bin/yabb/YaBB.cgi?board=concepts;action=display;num=1052330621 good luck, I'm happy to answer any further questions ;) BTW upload procedure put simply..... 1. burn the bootstrap loader, using IC prog 2. start up midiox, configure as per Thorstens instruction page (how to sysex, I think) Switch on the midibox, send the MIOS v1.2 within 2 seconds of turning on the midibox 3. now load the application, using midiox again (don't have to do the 2 second thingy this time) load the

if you are using panasonics watch out! the resistance when the wiper is at the end with the motor should be close to zero ohms, but on mine I measured 20 ohms! If it all works out well, let me know please! ...Steve

have you got the voltage regulator 7805 around the right way? If you have a multimeter, put test leads on pin 1 and 2, you should get 9v. now test pin 2 and 3, you should have 5volts (pin 2 is ground, so connect the black lead test lead there) when you look at the front of the 7805, the pins are 1,2,3 from left to right (leads poking out the bottom!) good luck, from Steve

Hi everyone, Look, all my 'boxes seem to have jitter problems. This jitter seems to come and go. It must be something to do with my local environment, as why dosen't anyone else have such problems... maybe it's something unexpected, like the brand of solder I'm using or maybe some of the components are not up to scratch. LO's panasonics work ok... and I've set mine to 7 bit resolution too, yet still no joy. SORRY TO DISCOURAGE ANYONE..... Sorry I've been posting over and over again... the same crap everytime... I'm too impatient.... anyway I'm going to lie low for a bit... let yourselves be encouraged by those who have had some success! BTW... I changed both the adc and mf deadbands to 5, and it was improved. ......Steve

Hey Thorsten, Thanks for the reply! I just did all those things, I removed the big cap, installed 100n, put a big thick ground wire to the ground of faders, deadband mf...8 adc....7, earthed my fader chassis,(previously I insulated them, wierd, but it got much less jitter... my electrical engineer friend said maybe it was a problem of Al panel, Steel faderdodies=mini battery) checked the panel earth, and now it is worse than it ever was :'( So, I think I'll pay an electrical engineer friend to fix it!! (I really wanna start to use this baby) thanks for all your help, it is much appreciated bye, from Steve

press'n'peel is very similar to the 'how to make a PCB' page on Thorstens site. The only difference is that you use a special plastic film to photocopy the PCB pattern on to ($35 Aus for 5 sheets, similar to A4 size) The pattern is then ironed on, just like on Thorsten's site, only it comes off easier, and cleabner. I fit my entire LC emulation on one board!! what are you confused about?? why not just take the standard configuration?? if you don't need all the pots, just ground the inputs you are not using. farnell is extremely expensive for the LCD. Dick Smith sells a 16x2 (=backlit version), oatley has 40x2. Jaycar also has a 16x2 good luck!!

OK, for the benifit of those who have bought panasonics... the best setup so far.... -6.5 volt motorfader voltage -0d  motorfader speed up/down -chunky cap (2200uF) across the 5v rails on adc input -another cap across supply for MF, after regulator -7 for adc deadband -3 for mf deadband -shorten all wires as much as possible now, there are no major errors anymore, when faders update, only small ones... say 0.4 db and once I had a midi value change from 100 to 95, but this size error is very occasional. <<<<<<update... bugger now they are bigger.... just ignore this post!!!>>>>>>> the faders hit pretty hard on their stops though, and there are still problems at the ends of travel... but this is only really a problem at the bottom... how often do you see volume faders at the top of their travel?? (except for panning hard right, or if you 'flip' to control other parameters with the Motorfaders) OK good luck, those using Panasonics, and if you discover improvements, please let us know!! BTW, if anyone is too scared to customise the settings to make a sysex file using MPLab and perl, I can help out. (for the first few times anyway)

As a last resort... Press'n'Peel from Jaycar... make your own.... Beware.... you will spend a whole day drilling holes for 5 boards or so... and sharpening a 0.8mm drill aint fun (unless you are a fitter machinist like me ;D he he!) you will need a nice drill, like a dremel... expensive :'( BTW oatley electronics in Sydney has good prices on LCD's they have a fast mail order service too. If you need pIC18f452 fast, then credit card Farnell. otherwise, just order from microchip, or maybe Dontronics ('877 only, I think) Farnell have cheap slider pots (but a bit crappy) and jaycar have cheap 16mm pots (not sure on the quality) jaycar have both 10mhz and 20mhz crystals now. btw, if your program has a midilearn function, setup will be very easy (like fruityloops, but then again midi implementation is very annoying on that program >:() BTW, if you use press and peel, get back to me, and I'll give you a few tips.

don't forget that only the real Mackie (latest firmware only) supports protools at the moment. from memory, I think PT supports the CM motormix... might only be for the faders though, but still, you may be able to follow this up?

oops... I just modified whilst you replied!
