moxi Posted January 19, 2008 Report Share Posted January 19, 2008 just to say:my MB based cem3378 analog filter projekt sound great......even when not feeded by any audio source : the LFO/eg/midi to cv modulation from the analog toolbox app make it sometime sounding like an unknow synth ( :D or :() , I'm sure it's some "self oscillation" (or other name could be ok for me, too) behind that...probably cause at some time you can have about 4 or 5 cv source that modulate the cv inputs of the chip, after being modulated one by the other on software side or by one of the CV mixer I've added...maybe that is related to some hidden "impedance" or other electronic thing I don't know or can't mesure...if someone get the answer...I'm curious..of course I can make my chip quiet or only acting as they must do...so it's not a problem, just an additional feature that will make it so unique ::)......Imho, I'm realy proud to have build my first analog diy synth ;D Quote Link to comment Share on other sites More sharing options...
stryd_one Posted January 19, 2008 Report Share Posted January 19, 2008 Hmm I wouldn't mind hearing an MP3 of that.... But I think it's "testing", because for "troubleshooting" you need "trouble" ;D Quote Link to comment Share on other sites More sharing options...
moxi Posted January 19, 2008 Author Report Share Posted January 19, 2008 sound will come soon, as all seems ok, I'm now reconnecting all the analog pots (about 24 ! ) and buttons to the definitive panel..I've done my test on an old keyboard amplifier, I'm for the while a bit frightened about pluggin the beast in my beloved sound cards, I prefer to try such a dangerous weapon first in the computer of my work's office ;D stopping kidding, it's why I've asked about some hidden electronic phenomen, voltage is ok - only a bit High when normal self oscillating of the rezonance - , but I'm not sure all is about voltage when we talk about damaging the target gear..

stryd_one Posted January 19, 2008 Report Share Posted January 19, 2008 I prefer to try such a dangerous weapon first in the computer of my work's officeLOL yeh it's not like anyone will care even if you do blow it up :)I know what you mean though... Amperage brought about by differences in impedance and such, it's all voodoo to me :/ Quote Link to comment Share on other sites More sharing options...
bugfight Posted January 19, 2008 Report Share Posted January 19, 2008 ...Amperage...what is this "amperage"? methinks someone needs to read their horowitz and hill...*whack* Quote Link to comment Share on other sites More sharing options...
stryd_one Posted January 20, 2008 Report Share Posted January 20, 2008 Uhm, I thought it was:am·per·age (?m'p?r-?j, ?m'pîr'-) pronunciationn.The strength of an electric current expressed in amperes.But then again:it's all voodoo to me :/ ;D Quote Link to comment Share on other sites More sharing options...
