perhaps this is a dumb question, but how do i change patches and/or edit sounds? i have no control surface and no bankstick (yet)

ok, i guess i'll just use a switching jack on the in, so it's always grounded when not in use.

well, i just connected the audio out again, and guess what... it now plays the tones i press on the keyboard. this silent sound i heard before is still there and exactly the same as before, but now the sounds that are supposed to be played are played in the foreground. wierd.

finally got around to measuring with the sid inside: 11.7V (11.73V without this time), so no big difference oh, one more question: is it normal that when the mbsid software is installed that i get all this when booting the synth?

i'll check tomorrow morning it's *still* to hot to do anything right now...

it is mounted as shown in http://www.ucapps.de/mbhp/mbhp_sid_v2.gif , with the heatsink pointing towards the big electrolytic. (and it's a L78S12CV )

theoretically yes, but since im moving away in less than 14 days its a bad moment, perhaps as soon as i'm in cottbus might be better. i do have other sids i could try in the module but considering that this one was getting pretty warm, im scared they might break...

i'm in germany (frankfurt a.m. for the next two weeks, after that, cottbus) so i'm pretty sure there's at least one person with a midibox sid :P but i cant think of anyone close by who has either.

thought so no, don't have any c64 to test the sid in... :(

nothing wrong on the interconnect test (unless it's a big error if i get 0.01V instead of 0V on CS# for mod wheel value 14)

ok, after solving all my psu troubles, i connected the sid module and the core module and powered everything up. uploading the midibox sid software went fine, but i'm getting nothing but a constant, fairly silent tone, of which i can change the pitch by pressing the keys of my keyboard (but the changes are totally out of tune and there is no attack or anything, and as i mentioned it's pretty quiet...). and the sid (6581R4AR is getting pretty warm) and yes, i did check all voltages they were a-ok, 11,8V for the sid and 5,3V for the core. edit: and the testtone app just produces some loud clicking/thumping directly after upload (just as after the upload of the sid software).

looks at board looks at schematic looks at board slaps head :-[ I hate desoldering... (edit:) because it never works...

ok, after solving my core module power problems i built the sid and to be able to test it i built the optimized c64 psu circuit on a piece of perfboard (though the way i soldered all that i might just as well have gone point-to-point... ::) ) but guess what! more psu problems! at the 5V pin i measured 5.23V (after getting 0V until i found a bad solder) but at the 14V pin i get a whopping 17V and the 7809 (and it *is* a 7809 not a 7812) is getting pretty warm pretty fast for there being practically no load... between pin 2 and ground i get 5V (as there should be) and between pin 2 and 3 of the 7809 i get 12V (not what there should be, this should be 9V)

i got my sid chip(s) on ebay. actually i bought a C64 but i talked a little with the seller and he suggested selling me a bunch of 6581's (two 6581's and a 6581R4AR) and a C64 psu for 15€ instead.

wohoo! i powered my core up, connected it to my motu traveler and got a nice steady blinking from my midi in port due to the upload requests. uploaded mios 1.9b: no errors. :D to do a little midi test i uploaded midi benchmark. seems to work great. on to the sid module!
