hi all! hi wilba.. i was out of the forum for many month, work.. girl.. work work work.. change home etc. i come back and i find this cool MBsid.. i've think, fk! i must take out my solder from the box! so i've a question, i've read the entire thread but i've not find answare. why you had chose 6582 chips? ;D good night 8)

8 for me if i'm not late, i've mail you!. n8 ;D

some R4AR form me? ???

me too, and this is an interesting solution.. ;)

this is my stupid tutorial for a self made midibox-sid (not complete tutorial, but complete sid): http://www2.autistici.org/ganchan/midibox.sid/ nothing special, but i hope this help.

who can suggest me where i can buy some audio and midi cables on the net, goob but cheap? thankyou!

uhm.. i think breadboard are useful during project testing, but MIDIBOX are all just tested, you need just to assemb and play it! ;D

uhm.. test what? Voltages or just position? i've a little tutorial not finished yet, see if it can help you about positioning. see at the bottom of my post. 8) ..or you means something like this? http://www.musicfromouterspace.com/analogsynth/STATEVARVCFFEB2006/breadboard.jpg

i've blamed 10 Fuse 200mA, don't know why. i haven't touch nothing on sid circuit. possible there is a little short around? now when i powe up sid, there is no start sound and if i play some notes i hear a very few prprprprr. tomorrow test. 500mA are too much for c64 PSU? 160mA was originals. night edit: tested all cable and circuit, no shorts around.. now all work fine.. ;)

I would like to build a 4 mono channel filter Cutoff/Resonance. Some one have a DIY schemantic for this? Thankyou! :D

yes, TK you are always right! but for now i've just my mono SID and i would play it too much :) 4SID are planned for next days (month) with my own complete CS! ..and for the CS i've some questions to make about, soon. thanks as always.

just HALF tutorial and some sound tests at the end of page. enjoy ;D http://www2.autistici.org/ganchan/midibox.sid/

;D another 2 quest: 1) i cant' find how can i change patchs by CC#, 0 is Banks ok, but Patchs? edit: find, just use program change on PocketDial and not CC#.. 2) i've a Pocket Dial with rotary endless encoders. if the cut off, in ex., is at 88 value, first time i turn the pot, it go to 0 first, than starts change values.. there is a way to program MIOS so this not happned, or changeing the type of send data, IncDec or something similar, so it start from the SID value that is? i can only preset the Pocket from where value each rotary must start.. tnx ::)

yes! as usual, you're right! i've don't understand if there is a way to play the 3 OSC separately like 3 instruments, like SID file DO, or not.. since i can assigh just 1 midi CH to the Core i think not... right?

Interconnection test passed :) just crossing 2 cable.. argh And finally SOUND!!! love you all :) tnx TK Wilba Seppoman Majo and all others.. SmashTv too!

i've do this test many times, but thankyou for patience.. reading your suggestion i've finally find this: >:( >:( >:( >:( >:( >:( >:( >:( >:( fj#d@sa#!!k$$d!! in pdf schematics MD J10 CORE is 1pin OVER MD J2 SID .. in the most recent relese J10CORE & J2SID wasn't 1:1 ?? :o M3 from PIC RD6 what is ? i go to excange cable on interconnection..! :-[ uhm.. RD5 is not connected to IC2 14 !? uhm.. and RD3.. and.. i've to study interconnection again..

tnx very good, i don't know why i haven't think this before :) the problem is that the led not light up when i send Modulation by MIDI-OX. i've tested all connection and solder of Jpins interconncetion CORE-SID, and are all oK.. >:( p.s. just the CS# work.. i think because in just connected to the PIC. at 08 & SER IC2 IC3 i've 5,2V but i must connect ground to IC pic and not +5V of multimeter.. it's right way? i've 5,2 in the others pins that are connect to SIDj2(from CORE) but i must connect +5V of multi to the pin. how to test if 74hc595 are sane? i've 0V if i test it with +Red multi on ICpins A0-A4 D0-D7, and 5,2V if i test them with -Black multi..

i've no LCD and i'm using a 8580. the voltage is 9V right. i want to check interconnection with the InterTest. but i've a quest: when i send a Modulation input, the voltage on the SID change just for a little time, or go to 5V since i don't make another input? there is no other way to test interconnection cable informatio between Core and Sid? my Pc and Core are too far to push SEND Modulation button and test the Sid Pins tnx

Probably your multymeter is out of alignment like was mine. I had +4.80V instead 5.20. You must open it and turn the trimmer since you have 5.20. If you can first, test it with another C64PSU, if you have 4.60 your tester is out =)

sorry, i thought that my PIC had MIOS just installed :) now all upload are OK! last for tonight, i can't hear any sound from SID. i've try to upload testone but don't work.. the question is, when i upload a new app, i must reup the 8580.hex for deapp the testone? thanks

tnx for replay! PIC are SmashTv pre-bootstrapped, so i think i must just upload the SID app right? i see all "OK" in upload control, in MIOSStudio during uploading, but the PIC never stop the loop Sysex message: F0 00 00 7E 40 00 01 F7. now, my SID 8580 became very very HOT! i've tested all connection and are all right.. it's normal? tnx

MIDI debbugged! now.. if i power ON the CORE, i will recive a loop like this: MIOS Studio timestamp 34946000 us: Sysex message: F0 00 00 7E 40 00 01 F7 timestamp 36838000 us: Sysex message: F0 00 00 7E 40 00 01 F7 MIDI-OX 000134C5 1 -- F0 Buffer: 8 Bytes System Exclusive SYSX: F0 00 00 7E 40 00 01 F7 00013C29 1 -- F0 Buffer: 8 Bytes System Exclusive SYSX: F0 00 00 7E 40 00 01 F7 some suggestion? ??? QUOTE from raphael: the brown-out feature of the PIC will reset the core, if the voltage is lower than 4.5V. So you end up in a reset loop.. possible?

argh.. no midi feedback from core :-[ test and test and test and...... test i've left a bridge not soldered at +5V midi out :P i've exchanged 1.2K and 220 resistors near Opto :o midi msg don't feedback but if i power off the circuit i hear a POOOWWWNNNN by the audio out, it will be possible? yes is the ground that power on.. if i touch the audio ground i hear the same sound 8) tomorrow mididebug day! goodnight

hi marcus! happy to see that you had finished SID same day as me! 8) i've just a little quest: had you connected the +14VDCground with +5VDCground? or you had left not cabled at j1SID? thankyou!

tnx wilba for help. the cheap psu misuring was only to see if the two multimeter was equal. since i've use Otpim. PSU schem, the ground of 9VDC stop at pin2 of 7809PSU, than SID 7812/7809 and others caps take ground from +5VDC like in J2 of SID PCB. 11.5 is at the 7812SID when +5VDC is connected at 7809PSU pin2 and with the ground like i've show first. mhmhm.. i must connect the 2 ground together? thankyou ..add: ahahah.. i'm so stupid! if i connect the 9VDC ground with 5VDC ground i short the +5VDC because of the pin2 7809PSU connected to +5V itself! :-[ 4 fuse blamed :o
