hi; wasnt this project discontinued? the way to go in short; get voltage control on every knob you want midi controlled; knobs like cutoff will have this implemented allready, but the ones that don't you will have to make v-controlled (with vactrols, OTA's transistors, search the net!) you can replace normal switches by... :P thats right; voltage controlled switches (or switches you can operate with triggers); once your analog filter has total voltage control you can set up a midibox; midi->cv (MBCV) module to control knobs and gate envelopes, an you can trigger switches with dout modules (MIDIO128).. good luck, marcel

regardless of the outcome, i'm curious; what is the advantage of using a different oscillator on the sid module; maybe we should just always use the core as clock, or no? cheerss

hi, preamp to a max ??? i know that my sid is not as loud as my other synths but this seems wrong to me (i amplify it a tiny bit more than other synths) i would just go thru the walkthrough step by step; and write down results; after this it would be easier to ask/answer questions. btw dunno if this makes sense but..have you checked the transistor in the output stage of the sid (right type, right orientation), i guess this is for amplifying the signal. cheers , marcel

hi, wisefire there are a variety of different din plugs; ones that will never fit your midi din sockets no matter how hard you push ;); the advantage of these is that you can never insert them the wrong way, and i think theire quite ruggid too. as of the ugly c64PSU; you could put it in another box (check conrad or reichelt); since IMHO they are good psu's (like you say 20 years old>still working) cheers and btw nice (+inspiring) building log

hi jeroen got it upside down?! ;) untill you have mios installed you will just see upper row of black blocks think the core is fine and bootstrapped! or you wouldn't have midi messages so now, uploading mios; do you know you have to upload mios within 2 seconds after powering up? hope this helps. cheers, marcel

hey florian; if you want some help; give us some more info whats the hardware setup/ software versions u are using; PSU; have you got an lcd (which makes things way easier)? Does the core module work on itself? cheers, marcel

hi; beta; as in the layout has been given for people who allready wanna use it in for example MBSID, but it's documentation isn't on the main site (only some info scattered around the forum)-->probably it's not completely finished but anyway i think that in future AOUT_LC can be used instead of AOUT anywhere>its going to be a low cost replacement cheers, marcel

hi joerg; the aout LC is still in beta so we have to wait for full implementation; but i fink it's commin ;D look some more in the forum for news/progress. if you don't want the aout pcb anymore i think i want it. but i'll get back to you on that. cheers

i dont get the point; if you connect midi from MBseq to MBsid to MBFM; you can use the midiout of the MBFM to control the external gear.. but this is the same with all midi devices that have midi out.. you can hardwire it or use standard midicables.. cheers, marcel

:o when does the madness stop;Â i'll try to make some patches too.. nice project

hi, just to be sure, did you adjust the trimpot for lcd-contrast on the core module? i dont know if this is possible cheers, marcel

hi; if the fx processor has midi implementation/control you could built it in the same case as your sid with the "assign encoders" controlling the fxprocessor. However if this is your only fx unit i would keep it stand alone; use it with the aux send of your mixer so you can use it for more things than the sid alone. cheers, marcel

tis the season! i like ;D, i think this is really wicked, bpm is also chosen with encoder? or it still must be a midislave no problems for the PSU i guess; and inside this extention just a din and dout module? and if people want more functions; they'd better built a mbseq! thanks!

can we have the .brd-file? i'm etching this weekend! by the way; is it (going to be) possible to put the s&h module with this? cheers, marcel

non polarized 10uF caps ? don't think so.. (they don't exist do they?) cheers, marcel

hi, one of the things a multimeter can measure is (electrical) resistance (in ohms) between 2 points; for instance (the legs of) a resistor; you can check if 2 points in a circuit are connected by measuring the resistance; which should be 0 ohm>> since a track/connection/wire shouldn't alter the electricity (it's only a connection right and not a resistor) cheers, marcel

hi; the easiest way is to drill pilot holes/use a (jig)saw and finish with little files, oh and lock yourself up with plenty of food and water, because this will take a long long time.... man i wanna CNC-machine cheers, marcel

hi; computers have switching PSU's (google it) and as far as i understand this can cause the voltages to have spikes/ be unstable. But you are using this PSU on it self or together with PC? using it simultanious with the pc could cause problems for sure. to be sure you can just test it with a regular adapter/wall wart and then fix it up with the PCPSU cheers, marcel

Hi; din/dout modules don't work on +/-5V just +5V, they are not suitable for generating control voltages (the dout module can be used for putting out (drum) triggers though); BUT the aout module (and the upcoming low cost aout module) are perfect for cv's and gates; The thing with the SID you were talking about is that you can include a AOUT module in the sid-synth which can forward the application's envelopes and lfo's to cv outputs cheers

hi, but they probably all have the same pinout, just different manufacturers. and look at the AIN module page, the pictures below show the right spot! cheers, marcel

Hi let me try to explain; MIOS is an operating system for for the PIC's which allows it to run programs like for example MB64-app, MBSeq-app, Change-ID app etcetera. You ALWAYS need/have MIOS before you are putting an application on. so you upload MIOS> upload change id/change id app. just do it and it will work... you will never lose this ability, PIC's can be programmed over and over again. and you won't lose the bootstrap loader i think you should read the bits on MIOS and uploading (again?) and then just try it. It's not so hard and if you got your hardware checked you can't really mess up something ;D cheers, marcel

no, defenitly not (says the little voice in my head) startprice 245 euro >:( and it's ugly too; anybody live in munchen? i hope this will be a short thread :-\

hi, no, synapsys says that you could go down to 200 ohms resistors without frying the shift registers, but this is just to indicate the lowest value you can take 4,7k is the same as 4.7k (you say "." i say "," ;)) or to be exact >> 4700 ohm, another way to write it is 4k7 these values ar (i think) not calculated; so it doesn't really matter as long as they are above 200 ohm you can try out which works for you but again only try this IF you have problems like pay-c said, maybe you don't have to change anything cheers, marcel

Hi not exactly, this is more like vactrol control: the light which falls on the photocell is changing it's resistance (you don't get steps). I've been experimenting with vactrols and IMO they sound wicked, as long as you don't get light from the surroundings they are pretty stable (so you could get nice center position as long as you get it right with the springs) and have a real analog feel/sound to them(read: they are not as quick as some other controls so you can hear it going to a stable value). haven't used them in controllers though so this might be totally different let us know if you try it out cheers, marcel

ok! :)
