hi; like Jaican and gbeth said; this soldering iron will probably fry your sensitive components. further, i like your "do everything myself" attitude, but are you sure that you can get it cheaper there; the uv pcb is 3,50 euro but then you need chemicals, drills etc. but whatever you decide; good luck with the project and band

your right the pcb's don't need to be changed; the first core module pcb also worked ;) but as tk said; it will be more newbie friendly and will hopefully result in less questions/confusion on the forum

more then interested! ;D got a bunch of analog hardware that love these kind of ideas.. if you need people to test, i'm up for it

;D Thanks; Thorsten and Francois, great new features if only my PC (i should say windows) would work....

yes this is tru; but i think you have to configure the MB64E app for your custom needs; you do this with MPLAB IDE (read the page on ucapps) It's not so hard; you just answer "multiple choice" questions; concerning your hardware setup>number and places of buttons, encoders, pots etc. Most of the changes are made in the main.asm file; open it in MPLAB and you'll see. Once finished; you can build the project, and a new main.hex file will be there which you can upload. yeah you can mix encoders/buttons; they behave similar (an encoder is kinda like a switch which goes up or down i don't think the dins could mess up mios so that it doesn't work anymore (it sould work again when you disconnect the dins) do check for shorts though> they cause problems when connected ok lets start over again; to be sure upload MIOS again but try doing this within 2 seconds after you power up the core (don't know if it's still neccesary but i think so). Then i think it's best to first get it working with only pots and buttons like before (on MB64). Check this with the program/ machine you are building your box for so you know the ain and din work properly. then go on with the encoders with MB64E. Last tip; if you got some money to spare; get an lcd! they make troubleshooting much easier. If you don't need it in this box you can always use it for the next ;D good luck, marcel

hi; what are the signs of life then? i fink you have something mixed up; the bootstraploader has to be burned with a hardware burner like the PIC burner module, it can't be done by midi. but you say the core is communicating; so you probably have bought a pre-burned PIC from one of the midibox-shops?? if so, you've got the bootstrap; now you should upload MIOS, and then the application you need (with MIDIOX/MIOSStudio.) good luck, marcel

hi; the only (easy) way to check this is to put them in a C64 and play a game or something so you can hear if it works. marcel

hey larry; check this out... http://www.midibox.org/forum/index.php?PHPSESSID=61b73881aebd68e2d1095099818beafb&topic=5680.0

hi; it's always safe to use a transformer wich is rated for a higher current (in amperes) then needed. so the 200mA the diagram is showing is the minimum your transformer must deliver. keep in mind that VA is not the current (like 200mA) but i guess it's the "current x voltage" it can deliver. something like 1,8VA means it can deliver for instance 18Volts with 100mA. for the core setup+lcd 500mA is recommended good luck , marcel

hi; well i'm sure it isn't a more advanced synth, more like a cut down version of the poly 800 (no keys; it's an expander unit); like the KORG EX-800 is. i think it's like this; the KORG poly-800 and it's little brother the EX-800 (without keys) have also been made by SIEL synthesizers (the DK-80 and the EX(pander)-80). The "EX" version has also been made by Suzuki; they call it the SX-500 (i've got this one) I'm almost sure all these machines have the same electronics inside, with some minor differences. so; let's hope it's true what i'm saying because then you can use this chart; http://home.tiscali.nl/~smeyer/siel/ex80andsx500sheet_ver2.bmp or check out the DK80 or EXPANDER 80 pages on this website; http://home-1.worldonline.nl/~smeyer/siel/ good luck, marcel

hey kokoon in the previous post i was going to say; "a lot of people don't know this" ;) i'm almost sure that everything can be controlled by midi, but as i said this isnt a well known fact; i will try to lookup the midi-implementation chart so you can check it out. cheers

hi people; i was checking out the mb-sid-d app and came to the conclusion that the patches i made are all pitched way to high; i think i was on the wrong octave when making it :-[ of course i was planning to fix them right away; but now i can't seem to get my MBSID working properly; so untill i fix this i can't fix the patches. no real problem; (they were quite strange/experimental anyway) but if you want to use them i suggest you pitch them way down to get the stuff i intended. cheers, marcel

hi; since your busy anyway; check out this mod on how to bring up pots/knobs for the cutoff and resonance of the (analog) VCF of this machine. http://synthmod.net/korg/moog_slayer/ i have a susuki sx-500 wich is a copy (kinda) of the korg (poly/EX)800 machines, so the mod was slightly different for me. it's a nice mod because with this you can make the filter self oscillate. also; all the parameters of the poly-800 can be controlled with midi cc's so you could make a nice midicontroller for it aswell ;) cheers

huh; people building mboxes in allen/heath mixer, and now acces virus cases ??? please tell me you never had the whole machine !!! and if you didn't >>how did you get an empty housing nice work anyway!!

hi; this has been answered 3 posts up?! it's reconfigurable these are normal functions of the control surface; read up on the MidiBoxSID pages. you could use encoders with switch for this but most people just put in a separate switch for these functions

so, change (match) the input impendance and you got a great (better) synth fx box... i know there are a lot of audiofreaks here ( consider myself one ;D ), but i think it´s good to say guitar stomp boxes have of course been used on synths-drum computers etc and can do the trick for you (it does for me) in short: i think the things moogah says are true but not everyone needs a "subtle" distortion (allthough i am of course interested in the schematics you will bring us) cheers, marcel

the legacy lives on... these people (Moog/Hendry/Simonton) influenced millions in a positive way.. now that's leaving your mark RIP

hi; first off this is actually a forum about building MIDIboxes only (check the ucapps.de site) but to rty and help you, i think your pic is not working correctly (maybe got no software or s-ware with wrong LCD-driver?) or you got your lcd wired the wrong way. A LCD always shows black bloacks when it's powered on but isn't getting any info. anyway; i think the e-drum forum is the best place fore you to ask; because most people here don't know anything about this project. cheers

hi, you could put the 2 synths in the same box (other people are planning to do this too) but they both have dedicated control surfaces which are quite different, because the handling/programming of the synths is different too. If you dont need the dedicated control surfaces you could just make the synths without CS but make/use a midicontroller (built inthe case) to control both synths. i would say; get the sid working for now, maybe in a temporary case; then build the FM, then think of ways of combining them. Mixing the 2 from the start might make (the eventual) troubleshooting more difficult, but of course this is still up to you! oh, and don't forget to buy encoders! cheers, marcel

hey meef you can configure your mbox exactly the way the VST is setup; you can make it so the 4 buttons act as radio buttons (so there is only one active at a time); you can make or buy buttons with leds in them. a rotary switch could work but like smidrin said maybe a bit dodgy. cheers, marcel;

hi you have java (runtime environment) installed? if not; please read the info on the (miosstudio) page befor asking questions.... i know that if you wanna upload stuff on your finally finished box, you can't wait for it to work, but still with no java installed you will get a zip file with different directories and files; but with java the zip file becomes a jar file if you do have it;Â ??? dunno marcel

Hi Synth-o-mania is right; jacks shouldnt be powered unless you wanna blow up your speakers!! For the sid (and most other synths) you don't need stereo jacks because it's a mono signal (like for example a guitar) a mono cable has 2 wires; a wire with the (audio)signal and a wire with ground connections; typical mono jack plug: ====> the "====" part is the body (or ring); you connect this to ground the ">" part is the tip; you connect this to your audio signal so if there are more then 3 pins (on a stereo) jack socket you've got a switched socket; two of the pins (one is usually connected to the tip) are connected together when there is no jack in the sockets; this connection switches off when you insert a jack. hope this helps explain

no you actually have to do something yourself.... ;) you can buy kits though; you have to solder the modules yourself. this is a non commercial DoItYourself only project>> more fun, educational, you name it ... this forum will help you with problems you will encounter while building; just try and make sure you read all the relevant info on the ucapps.de site, the Midibox WIKI pages and the forum before; because all the info you need is probably allready there!! good luck

It's all possible with :o MIOS; (M is for Magikk ;)) midi>cv; MIDIbox CV (hardware; core module + aout or aout_lc module) cv>midi Midibox64  (hardware; core module + ain module) cheers, marcel btw; there are quite some people in this forum (including me) really interested in (and working on) these subjects; controlling analog with midi so... you've hit the right place

dontthink this will solve your problem; bout the transistor; you could try and find a datasheet, but i couldn't (is it really a CBC547?). BTW did you buy a kit from mike/smash?>> if so the parts you got will be fine, your problem will be something else. of course it could be a fried SID; but there is no quick way to test; you could put it in a working C64 and try a sid tune from a game or so sorry i can't be of more help.. goodluck, marcel
