thats better..

dont want to use a din plug at all.. there are a couple of other plugs i have in mind.. as for the c64 psu.. ok its sturdy.. but still.. wouldnt the PSU's be better nowadays? also.. when it breaks i have 1 backup.. but if i use a standard 12v ive got a shop full.. on the other hand.. the c64 psu will probably save me some work.. no wait .. the psu otptimized is work aswell. its a dilemma

hi synt-o-mania, im kind of looking for the old types.. but as my current chips are new types.. staying true to my current voltages is an option as well.. so both versions will do.. what I have instead of a c64 PSU is the following: simple 100k ohm exponential faders.. 14 of them.. and: the buttons to go with it.. well 13 buttons.. maybe ill find the last one as well.. they where of a diy mixer project which i didnt finish.. so they are "new", unsoldered and unused.. if you are interested.... or anyone else.. just reply..

good thinking.. [X] indeed does look cooler.. ps: actually i dont have a mox emerald or any of the moxes.. i wish i had a black lotus though..

hey smash, im actually using a mobilephone.. a k750i.. its not a great cam.. but for a telephone cam is suprisingly good.. its a 2 megapixel cam.. in darker lighting situations it does streak and give noise.. but for day shots its great.. i can recommend it as a mobile device.. its fully featured and a real to work with it.. its menu system beats the daylights out of the nokia system any time :P [/irritating infomercial rant] ok, and .. but what about Trading.. as in i want your "lord of the pit" and ill give you my "mox emerald" for it.. or: ive got a 220 ohm resistor and im willing to trade it for a 1.2K ohm resistor.. you know.. serious trades..

WOW, ive been mentioned in the MBSID walkthrough.. CEWL! THNX for the great compliment TK! ive been busy again.. as i now have sound, i have proof of concept.. so i soldered a plug to my 40x2 LCD. this is what i saw.. IT WORKS.. well, i soldered it correctly.. but now i want some usefull info.. so i uploaded the CS .syx and then i saw this.. but still, it wasnt a lot of info.. so i descided to solder my banksticks.. its a bit big for just some chips, and it took me over an hour to get the connections right.. well it was 3am so i couldnt see straight.. it even formats them!! that was all yesterday.. today ive built it all in a case.. doesnt work as of yet.. the 7805 gets very hot.. cuz of the voltage difference (im pumping 12V into it) however i dont want to use the c64 PSU.. it ugly probably more than 20 years old.. and it will mean that i have to find a nice looking plug to get both of the voltages in.. i dont want to use the 5 pins din plug.. as i can plug that into my midi.. dont wanna go and do that huh.. so i think.. a seperate system of multiple regulators that step down the voltages? i dont know.. any tips? ofcourse the photos.. remember its TEMPORARY.. but it'll give me a nice testing ground for the CS part of the synth.. as i will eventually have to build it into a case anyway.. oh, and the wires from my lcd keep snapping.. im gonna put some dil headers on my lcd.. otherwise i might break it with to much soldering on it.. thats about it again..

hey, nice idea this flea market!!! ive got a spare c64 psu.. and i would like to trade it for a sid chip!!

building one is half the fun.. and NO there is no one here that is willing to build you one.. build it yourself.. its not that hard..

i found this website where they explained how to make a vacu form table (its very easy) and how to work with it.. also some info on how to make a mold for it.. and a lot of other great stuff.. check it out.. http://www.studiocreations.com/howto/vacuumforming/index.html http://www.studiocreations.com/howto/vacuumtable/index.html http://www.studiocreations.com/howto/plastermolds/plastering.html

you are absolutely right kokoon.. my mistake.. made an error while encoding.. they are updated for full stereo goodness..

hmm.. so the most important thing of the optimized psu.. is the fact that you dont have to buy a power supply.. it does makes sense.. maybe ill do that.. or maybe ill go for a nice 1 amp 12v power supply unit to power both.. a nice modern one.. @ kokoon: thnx, indeed its joy.. even more when you go all kernkraft over it.. its cewl.. (as you can hear in the following mp3'z) http://student-kmt.hku.nl/~ijsbrand/midiboxsid/sounds/stompme.mp3 full stereo.. left and right are recorded seperately http://student-kmt.hku.nl/~ijsbrand/midiboxsid/sounds/stompme2.mp3 with a soundforge reverb over it.. but how did i get my snr so nice and low?.. good psu to start with.. ive got a stabilized 1.5 amp psu, which doesnt give me hum.. and ofcourse my soldering is good.. that helps as well.. and luck.. dont forget luck.. oh and good grounding..

well.. i owe you guys a good bedtime story dont i.. ive got some pics of the building of the last core and sid.. but quite frankly.. those pics are very boring.. instead im gonna tell you how it went from there.. after they where completed i started testing my core module.. checking the voltages as described on the core module page.. everything looked good. allthough its a bit odd that i have to power my core with 7.5 (or later 7) volts instead of 5 or 6.. but so be it.. the next dayl i stuffed the pic and the optocoupler in.. and started midi-ox.. i configured it as described on the bootstrap loader page.. and uploaded the mios OS.. it was a bit confusing at first.. with all the different pages i have to wade through.. and i didnt know that you'd have to upload mios AND the sid application.. however.. when reading this was explained to me very clear.. moral for aspiring MBSID builders: ALWAYS READ THE DOCUMENTATION (if you can find it :P) when powering on my core with pic, i inmediately became excited, because it gave out some sysex message (didnt bother to search for what it meant) every 2 seconds.. this meant it was working according to plan!! so i uploaded mios.. and tried out another pic..and uploaded mios on that. and my other core.. and another pic.. and uploaded mios again.. at least i think i was uploading mios.. as i didnt bother to read the documentation i didnt know what the sysex messages it sent back meant (at least i think it was sending them back.. didnt bother to read that either..) well after that i went to bed.. so earlier this evening i wanted to hear it.. but i was very affraid of damaging something.. i began the difficult task of wiring my sid module to my core.. this was not an easy task.. but im not that big of a noob.. so it wasnt THAT hard.. but still not as easy as wiring my core to work.. the only info on how to wire them both together is a PDF with info on how to wire it to a C64 PSU.. and i didnt want to do that just yet (as it would take to much time) i didnt know the sid needed 2 different voltages.. it consumes power from the core module and it needs its own 9v (for the8580(actually i gave it 12v as 9v wasnt enough to get it through the sid voltage check succesfully)) but hey it had to be the way.. so i wired that to the 8pins dil header.. it isnt a 1:1 connection at all.. you have to put 5v in there.. and you have to relocate a wire.. its odd.. but luckily thats all it is.. now the audio output.. why the ground of my audio output has to be connected to the ground of my j2(5v OUTput on the core) is a bit of a mystery to me.. but i dont mind.. as for the weird connection with the c64 voltages.. NO WAY.. so i thought i'll just let the rectifiers and the voltage regulators on the modules do their trick.. thats what they're there for.. but.. my voltage regulator on my core was getting very hot.. which i didnt notice at first.. luckily in not the guy who leaves the setup running while taking a smoking break.. so everything still worked.. had to find the problem though.. first i thought it was the fact that i was running 12v through the thing.. so i switched to 2 different wall warts.. one for my sid and one for my core.. nope didnt do the trick.. then i noticed that my ground from my weird connection with the sid side of the data plug was mixed with the 5v on that same plug.. so i switched.. didnt work.. then i noticed i had exchanged the ground from my audio out in the process.. so finally that did the trick.. next up was stuffing the sid and the 2 other IC's whatever they may be.. so i switched everything on.. at first no sound.. (even when receiving midi) so i checked the wiring.. it was all good.. however i got speakers that check for sound.. and if they detect enough of it.. they switch on.. so i started cubase.. and made some noise with my machinedrum.. (had to power down the core for that as it was using the MD's power supply (a 7v AC wall wart..)) the sound of the machinedrum made the speakers power up.. and meanwhile cubase had started.. so i powered it all up.. configured cubase so it would send my mbsid setup the midi it received from my keyboard.. then i heard it.. yes.. YES.. it worked.. a cheezy monophonic sound.. but it worked.. of course i inmediately tried to play something.. im not a good pianist.. let me rephrase that.. i cant play to entertain anyone but myself.. but i recorded it anyway.. http://student-kmt.hku.nl/~ijsbrand/midiboxsid/sounds/mysid1.mp3 then i tried the cubase arpegiator midi filter on top of my notes.. http://student-kmt.hku.nl/~ijsbrand/midiboxsid/sounds/mysid2.mp3 then i tried the vst plugin.. didnt record that though.. as i couldnt get a decent sound out of that.. the arpegiator knob.. what ever it may do.. didnt do anything.. and it all did some weird things.. but thats probably me.. not understanding it all.. ive noticed the steppiness of the filter and the unimpressiveness of the resonance.. ive played with the modulation thing.. wish i could modulate more than only the pwm pitch and the filter.. looking at the machinedrum.. with that i can modulate everything that has a knob.. also tried my second sid chip. worked aswell.. this is how it looks.. its not pretty.. but it works :D edit: the bass sound is nice..

van harte gefeliciteerd..!!

programming pong in assembly

eyes, ears and voice given.. and it saw me and it whispered softly into my ear... "NEED INPUT!" now if thats not something to be psyched about i dont know what is!

still sick.. but ive finished the core and sid module.. ive tested the voltages on my core aswell.. it all works but i have to give it 7.65 volts (my "stabilisiertes netzgerät" says it gives out 7.5 but hey) and the voltages are .05 to 0.08 volts over but that could be due to a very cheap multimeter.. so lets see whats next.. stuff it with all the.. stuff.... and give it some ears and a voice i guess..

nope, its not too late.. but be sure to read a lot.. all the info is here somewhere.. a good tip is to buy all the components from one supplier.. there are 2 webshops that sell complete packages.. so you dont have to hunt for components yourself.. and they are both pretty cheap.. ive ordered from both the shops and in my opinion the one smashtv has got is better.. http://mbhp.coinoptech.com you can order a lot for the control surface from him as well.. love to hear from your project as time goes by. good luck with it.. ps. how can you be hungarian and still be born in slovakia? hungarian parents??

here is a good tip: read the documentation.. allthough it can be confusing at times.. it something all newbies should do.. you could read the forum.. you could ask google.. you could even read my own topic.. as im building a complete CS sid aswell. its clear that you didnt do that.. or didnt spend a lot of time doing that.. what modules for a complete sid? http://www.ucapps.de/midibox_sid.html some core and sid modules and 3dinx4 and 2doutx4 what chip? ive read somewhere that the 6581 is a chip for "commodore sound" lovers.. and the 8580 is a chip for serious synth stuff.. im building mine with all 8580.. price? that all depends.. some people pay 4 euros for control buttons.. i payed 35 euros.. sope people pay 100 euros for a frontplate.. others make it themselves.. it up to you how much it'll cost.. im dutch.. so english isnt my first language either.. but it didnt stop me from reading a lot of the website.. i havent read it all yet and ask stupid questions sometimes aswell.. but its a good idea to read a lot and ask questions about what you have read.. so people know you atleast took the effort of reading the documentation.. good luck with your MBSID.. its a lot of fun to build..

i got my order in from SmashTV.. this includes the PICs.. YAY.. unfortunately, im sick right now.. so im not able to a lot.. no testing or mios uploading just yet.. but i did make a nice little photoshoot.. IMHO overkill for some electronic parts.. but at least i am sure nothing got hurt in the transportation process.. Nicely packed :P a lot of stuff... Core module parts.. Sid module parts even the various chips are packed seperately!!! WOW.. TOO MUCH PICs.. nah.. i can use them for a lot of things :D the encoders look nice.. but feel a little cheaper then the ones from voti.nl i do need these things.. but not 300 of them i guess.. THIS is what i would like my PCBs to look like.. NICE!!.. im going back to bed.. ugh..

jup thats the knob i used.. i ordered a free sample.. evil me.. i use mec switches aswell.. but i got them from a dutch supplier.. but payed about 35 euros for 42 switches..

@drin: if im not mistaken mine have the following stock number..467-6005, however this could be different within the english website/company.. @Titan:zou ik ze um bijna kunnen komen ophalen :P get the price as low as you can.. and get as much people into it as possible.. make an english version of the post in the german forum.. i for one cant really read german well.. you can get some more participants that way.. good luck..

hey TK (and others), i have some problems understanding the functionality of the MBSID.. as i dont have a operational MBSID yet.. however i AM designing the interface of mine.. and as im quite radicly redesigning it.. i was wondering some stuff.. i am deducing my info from the frontpanel itself.. osc: how does this assigning business work.. filter: O1 O2 O3?? can i remove ext from my MBSIDS fuctionality.. or wil mios detect(???) that i dont have an external filter thingy? mode 3O??? maybe its one of the above.. but if i have for example 4 sid chips.. can i filter my sound through all the filters of my sid chips (serial, instead of paralel) env: how does it work in general.. it raises all kind of weird questions (like: if i got 2 envelopes there.. why not hardcode assign them to the CTRL options you got there) i feel like a noob again.. but since i cant find a manual (and will write one, when i get my S*ID :P together..) im just asking.. edit: i was also wondering if it is possible to change some code to include a more direct arpegiator section.. i want to be able to switch it on and off with one button and change some of the parameters more directly.. (basicly i want to sort of mimic my MS2000.. as i am basing my design on that thing)

@titan: good.. i understand there will be a mass ordering.. when will this order be placed.. do i have time to make my design? if i can participate in this order, i assume it will be even cheaper.. and thats a good thing for me.. as for you other people.. here are some self explainatory pics..

i dont understand.. because its less than 500 grams its to expensive?

hey all, ive been neglecting you guys havent i.. no photos.. no amazing stories to tell.. But i have done SOME work on my MBSID.. i am now in the slow process of making a frontplate design.. slow because i have no knowledge of how autocad works.. but so far its going allright.. also ive been in contact with SmashTV, who has programmed my PICs, and has sent them back with my order from him.. ive ordered a second core module and a second sid module. also some other stuff.. like a encoder that clicks.. and some female sil thingies.. to connect it all up.. in the end, ease of use triomphed over monetairy problems.. but ive ordered about a 100 of them instead of 300.. so i will choose what i can disconnect and what i cant..also ive been prebuilding, testing if you will, the led matrix.. to see how it will turn out with mec switches.. and imho it looks really nice.. check it out! you can see that its pretty big in comparison to the standard matrix design.. ive used a protoboard.. or whatever its called.. with 3 holes grouped together.. and it should work perfectly.. now for the autocad design of it.. as for the mec switches beneath the LCD.. it should fit perfectly.. ive tested it.. and its perfectly alligned.. in about 10 days i will receive my package from smash.. and then i will hopefully have something to show and listen to..
