I bought a c128 to get the sid chip. Are there some other parts that could be used for a MIDIBox SID project ?

Bonjour à tous, Comme vous je me lance dans la création d'une mIdibox. SID en ce qui me concerne. Je suis encore à la phase de renseignements et d'acquisiton de composants. J'ai le sid (6581) et le LCD (http://maxitronik.blizzerver.de/ebay/R2X20/dv20210.pdf) pour le moment. Je compte acheter des kits. J'ai posté un thread en anglais ici http://69.56.171.55/~midibox/forum/index.php?topic=3913.0 Si vous pouviez faire un tour et m'aidez... En gros je veux faire un SID mono avec LCD, matrice et quelques encodeurs. Je cherche une alime de C64 pour le moment puisqu'apparement c'est ce qu'il y a de plus simple à utiliser. Mes questions sont donc dans le sujet. Si vous ne parlez pas anglais (mais j'en doute) je reposte l'intégral ici. Merci

I bought a second hand C128 and I thought I'd get a 8580 chip but I got a 6581. Have you seen that already ? Maybe first ones that were made had the 6581 ? Is it the same one as the C64 ? I asked that coz of power supply...

Thank you all for your replies and sorry for the delay... Now, I've thought about all that over and over and I decided to make a simple SID for a start but with some enhance control surface. What I'd like is to have the modulation matrix mainly, along with some basic rotaries for cutoff, reso etc. From what I understood, 1 Din module makes it possible to have either 16 knobs or 32 buttons. Is it possible to have on one Din for instance 8 knobs and 16 buttons ? 8) So for 1 sid with LCD and Matrix I need at least 6 + 15 buttons = 21 buttons. If it's possible to mix buttons and knobs in one DIN, there is room for 5 knobs, am I right ? One is reserved for menu navigation and thus 4 are left to be mapped to anyting I want 9) Now, the important question I asked myself is: Is it possible to change the mapping of these 4 knobs whenever I want or do they have to be mapped in the cs_menu_etcetc file once and for all ? For instance can I have the first button to be mapped to cutoff in one patch and then assign it to env 1 attack in another patch (or even change it in the same patch) ? In that case 4 encoders could be enough to have fun and control all the parameters... 10) What I need in that case: 1x Core, 1x SID, 1x DIN, 21 buttons, 5 knobs, 54 leds (for the matrix) -> 2x DOUT or 1 ? 1 Bankswitch. Is it correct ? 11) I don't have a C64 power supply. Is it better and cheaper to try to get one second hand or to buy another one ? What kind of ? I didn't understand the bit about the 2 power supplies that are needed for the SID 12) I intend to buy at smartTV so that they burn the bootloader. But what number do I have to give. I looked at the Pic ID calculator. Sysex I'll left to 00 since I only have one SID, right ? But what should I chose for LCD ? and I/O type ? I guess for the later If I don't have the LTC I have to chose Midi. Once the bootloader is burnt I'll be able to update it simply by sending sysex, right ? So these are the questions I have before ordering. Once you helped me with that I'll be able to place the order... Thanx in advance :D

Hi to all, I've been thinking of building a MIDIbox SID for months and now I'll make the big jump. I live in France, I'm new to electronics and I don't know much, except that I've already soldered components in my my life ;) Basically what I want to do is that: A Midibox SID with two 8580, mainly for stereo use. I want to have a LCD, some knobs and of course midi in, out and thru (if that last one isn't two difficult to add). I've browse the site but I'm still confused on what part I need. I'll probably buy some premade kits (from http://avi.dezines.com/mbhp/index.html probably) 1 ) So what do I need for what I want: 2x CORE Kits 2x SID Kits 1x DIN Kits 1x DOUT Kits 1x 2x20 LCD (btw is this one ok http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewItem&rd=1&item=5746937894&ssPageName=STRK:MEWA:IT ?) 5x Rotary encoders (with switch ??) 1 small PCB for the LCD LEDs ? What else ? 2) I got a c128 without power supply. I'll get a second c128. Can I use the C128 power supply for the whole project ? Is a C64 power supply better ? 3) Since I plan to order kits, what about the PIC18F452 bootloader/PIC ID header thing ? I didn't understand that. There is an option when you order to have it programmed. How do they have to be programmed ? Both PIC programmed the same ? 4) Then once I got all the parts, is it just a question of putting them together and solder (more or less of course, I understand that since every MIDIBox is custom made, issues are inevitable, specially as far as power is concerned) ? 5)Do the kits include all the parts ? For instance are DIN sockets included for the MIDI in/out ? Another stupid question: where do the audio plugs fit in the scheme ?? Is it simply a question of soldering one plug from the SID PCB to the audio plug ? Jack ones are preferred ? 6) Off topic: Is the MIDI FM easier/ as easier/ more complicated to realize ? For I just listened to the demos and I'm really impressed and it's the kind of sound I'm into. 7) Thanks for reading and being my guide. I'm really sorry if these questions have been addressed already. If I should read the all archive instead of asking newbie questions, just let me know. Cheers 8) 3
