sorry here also... tried 3 versions of autocad 3dstudio and Illustrator... no joy. :'(

naawwww, Dr. Who (especially Tom Baker) has quite a following in the US at least. I do like the industrial (floormat, stairs) look of the housing. :) gb

still on Jaguar here... sorry

i think i m might be confused.... tk/tck/tcl was originally an X / X window based interface... not sure how that ties in with JAVA.

geez, wish i had cyrillic alphabet on my pc... a POLYVOX !!! wow. a buddy of mine had one of these he got ... i guess 5 years before the fall of the CCCP. he had no idea what he had.... gave it to somebody that turned it into a PLANTER!!!! of all things. I don't think you should hack into it. Leave it as is... build new stuff if you can afford it. good luck gb

The simple answer is... YES! The complex answer is.... for adsr.... you are going to need a voltage controlled ADSR... they are out there on the web. I believe you can programatically set the outputs of the midiCV but I am only using it for gate for envelopes and voltage control of oscillators. These being modular in design. Now as to being able to control YOUR synthesizer... I guess if all the knobs and controls of your synth are midi based.. like a Korg ms2000 or a Virus or Nord modular, then you could assign midibox controls to your synth.but.... does that not kinda seem like overkill? maybe I don't quite understand what you are trying to accomplish. a bit more info please? gb

Yeah, in Canada, you will want to contact SmashTV, he's in Oklahoma, USA. here's the link to his site: http://avi.dezines.com/mbhp/ good luck gb

It is a modification to the MidiBoxCV application.. really simple tho... just uncomment the J5_dout lines.. or something as close. In my case.. I have 2 options... 1. J5 (usually where the AIN/pots hook in) drives the extra 8 gate outputs as per TK's spec. I just have not added the plugs to the faceplate yet. 2. J5 drives my modified V/Hz (ala PAIA FATMAN) D/A converter, to drive all my old V/Hz gear. The buttons are simply hooked into a 1 chip DIN (j8 or J9 I think) stuck on the same board as the CORE (i make my own boards) BTW, I have just this morning added another of Ray Wilsons retriggerable (with leds!) envelope generators... now I just need to make about 4 more VCO's a couple more VCF's and then maybe a midibox SEQ on the top panel to drive it (when not keyboarding it, that is) ;D gb

Steve, yeah, sounds like my house! :) BTW, for this latest analog synth I am using/modifying the circuits of : http://www.musicfromouterspace.com/analogsynth/old_synthesizer.html they are all rock solid performers, the parts are inexpensive AND he gives you gif's of the PCBs! very impressed with Mr. Wilson's work. gb

p.s. I have looked into the ele4music stuff. It was interesting, I have not made up my mind about it tho. They are located in Houston, as am I ! but I have yet to find thier physical address, I would like to pay them a visit and see what makes 'em tick!! gb

Steve, Yes, it is the full version, a bit modified. In one configuration I use the J5_Dout code to get multiple gates, in the other configuration I use J5 to drive a modified PAIA D/A converter so I can use all my old V/Hz gear at the same time as newer V/Oct gear. As to how MB-CV handles itself, It works at least as well as, if not better than my Midi2CV8 from PAIA. In fact because of the DACs TK used, it is even more accurate. I did not spend the money on the DAC's, I got samples (2) each of the DAC's and VRegs, from the manufacturer. (not looking forward to paying full price for the DAC's I will need on my next MB-CV project :-\ ) however, I believe TK is working on an R2R ladder style DAC using cheap discrete components, and I think it will hook into standard Dout pins as interface.. I use various inputs as MIDI. For music recording / sequencing, I use Logic Pro. Also for performance, standard cheap midi keys... (midiman keystation49, kaysound MK-4902). I also have an old (80's vintage) homemade ttl/cmos 32 step seq. I am seriously considering as my next midibox project..... MB-SEQ.

I have finally started to put modules in the midibox cv project. http://www.ggbnet.com/midiboxCV.html have a look, more pix and text will be added as I finish more modules. have a GREAT DAY !!! gb

it might be a ... DPDT double pole double throw switch yer thinking of Marcel. i could be wrong... (and if I were Adrian Monk, i would follow this with) but i'm not. ;D

Ahhhh, otay!

What in the world are these Karma rating things under the username? Do we get only so many 'Smites' and become persona non grata?

I would think that you could interface it to one of the AIN pins.. and do some code. it won't work with the fatman or any of the older style wave form generators...(well.. i guess it would, but if you look at the website they say the response is all at the lower end.... so it's hard to control with V/Hz response type VCO's.) However.... that having been said.. it could be used with V/Hz response type VCA's and VCF's... because our audio response to amplitude is exponential. but... if you are trying to control 1V/Oct gear, I think it's a cheap alternative...kinda... i am thinking about purchasing the kit from paia for just the manual.. and the strip. I do think it would be an easy interface to the MidiBox... for now, I will just make noise with it ;D

John at PAIA has one also, and as usual all the schematics are available for 'fair use' ....check out thier ribbon controller http://www.paia.com/LabNotes/index.htm gb

silly question on my part... but are you sure the voltage regulator is a 7805?

OK, here is a link to all the modified boards I have made.... DIN, AIN, AOUT, MF, CORE with cheap Resonator, DOUT ..... (single board... single sided...burn 'em ur-self and sell 'em on SchmeeBay) http://www.ggbnet.com/midiboxSales.htm They are all for sale..... ::)

Soldering Iron of Justice Smash... you slay me ;D

I have built 4 midiboxes over the last couple of years and am working on 2 more now. I have used the ceramic resonator at the link below without any problems. they cost $00.45 USD each. not sure why the expensive crystal/capacitor is needed. http://www.ecsxtal.com/pdf2/ZTT.PDF accuracy has not seemed to be a problem with this... my moog modular midibox has 3 cores and timing seems to work fine. my next project will be MBSEQ, we will see if my setup is accurate enough. BTW... since these things have 3 legs, I modified the PCB of the core to accomodate this resonator, oh and it mounts on the 'parts' side of the PCB, not underneath. gb

Dag Nabbit!!! Now you guys have me wanting to build MBSEQ !!! just to drive my MS2000R!! I was happy with the built in arpeggiator but now you have me wanting to try this... (actually have been thinking about MBSEQ for a couple of months now, using it with AOUT to drive old analog stuff in sequence) Life is never boring around this forum !!!! :D gb

will do!

EUREKA!!! I got MidiBOX-CV with the J5_DOUT to work completely in software! Thorsten, the code you sent back in January was what I needed.... just didn't have enough programming skills to find where the problem was. Code: TABLE_ADDR MY_TABLE movf MIOS_PARAMETER1, W ; (contains the note value) TABLE_ADD_W ; add to table pointer tblrd*+ ; read byte from table movf TABLAT, W ; result in TABLAT ;; now you can do what you want with the new value it took me until today to realize... Parameter1 was NOT what I needed.... that's note on... i needed the key value.. that's parameter '2' changed the line above to movf MIOS_PARAMETER2,W and It reads my table and outputs the data I need for my strange D/A converter... this let's me get rid of the 3 extra chips which I needed to do it in hardware. THANX TK!!!! ur the best! gb

my 15 watt uv works at 5 inches from board for 8 minutes. I guess you could work out exposure time based on wattage and distance from board. light falls off at the inverse of the square of the distance... i think i said that right.... so if my 15 watt bulb burns in 8 minutes from 5 inches... it would be 16 minutes at 10 inches 32 minutes at 20 inches... etc. also, i believe generally that the wattage of a bulb is porportional to it's length.... approx. 4 foot bulb = 40 watts or so this being about 2.5 times the wattage of my bulb... if your lamp is 5 inches away the time to burn would be approx. 3.2 minutes. I know the photo boards are expensive, but i wasted a few when i started because there was not a good histogram with the light kit or the photo etch boards. good luck
