Smithy

You could try asking him how he tested the chips. If he just used a c64 to test one, the filter could still be dead, lets face, most sid tunes in games etc.. do not use the filter at all. The fact he mentioned midibox and sidstation is looking good though, and if you look at the feedback some people have already installed them and tested them out.

The CC implementation is great, i had fun using Fruity's midi out plugin to play with my sid. I would really love to be able to control midibox sid with my Novation KS4 keyboard, without having it connected to a computer. Unfotunately i cannot change the CC and NRPN numbers on this controller, so i would like to change the MbSID paramater chart for my own needs. Can anyone point me in the right direction? Is it a case of simply editing sid_cc_table.inc for the CC numbers? And which file would i edit to change the number of the NRPN's? Also if anyone can recommend a better VST than fruity's midi out, to forward CC and NRPN changes, that would be great. I was thinking of making a simple VST for controlling the SID while we wait for the other one to be finished for V2. Using something like synthmaker, or synthedit.

Yep, without TK's guide i wouldnt have known where to start, sid dump seems the easiest option. Id love to be able to code a java based patch ripper, but i think its a bit above my skills!

Its time to finally replace the mdr-v700s. Can anyone recommend some closed backed headphones, with similar performance or better? I dont need them to be able to swivvel or anything, my ears are long so the HD-25's are out unfortuneatly. So far the Sennheiser HD -380s have caught my eye: Any ideas if they would be a good replacement? Cheers!

I think we should have a sticky of a SID Patch Thread, where people can share patches or Banks. I still plan on ripping a lot of patches from sid tunes, once i have the minimal control surface done.

Flemming i take it this extra diode and resistor differs to ones that are right next to the opto, and which are included in the kit? My single core, single sid setup is working *almost* perfectly, when i change the note while a drum engine is being sequenced, the sound tends to go screwy, all most circuit bent. Normal patches work fine, but the Techno PWM patch seems a bit noisey, so im thinking its the patches which use modulation, or a certain connection to the core like CLK, or another pin(s). I wonder is it because i havent these extra components its happening. but then again, theres being plenty of people who have had no problems after completing a kit, without using any extra parts, so that kind of throws that out the window too! LOL

If you bought them from Smash TV then his site has the documentation for the old revisions of the PCB's also. http://avishowtech.com/mbhp/info.html Just click the module you want to see, and click the big link in the red font that says: "Click here for documentation for past revisions"

Smash TV made a good diagram of whats going on with the waveforms, as they pass through an optimized circuit: http://www.avishowtech.com/mbhp/ps/ That circuit is of the optimization circuit in the core, not the c64 psu circuit, but the exact same principle applies. . Move your mouse over each signwave inside the boxes, to see what waveform forms in that point of the circuit.

The reason the LED has 3 pins instead of 2, is because the original sil connector for the C64c LED is 3 pin, not 2 pin, even though 2 pins are only used. So its basically so it can fit better. My diagram of the optimized PSU might help you visualise it a bit better, (of course it might do the opposite too! :P) http://www.midibox.org/forum/index.php/topic,12375.0.html Im using a different type of protoboard though, each pad is interconnected like a grid, unlike normal board that has parallel lines.

P.S. Can i pls haz a circuit diagram of favicon.ico? ???

I don't agree with you,I think This problem should be further analysis LOL

I've been a bit lazy updating this lately, but anyway i went on to do the bankstick module. I decided to reuse a Serial Cable from an old PC, which connects the motherboard to the 9 pin male connector. Perfect for use with a bankstick. Since ive lost my phone, i had to take pics, using a Camcorder hooked up to a TV tuner card in my PC, (Not the best way, but it damn well works!) Then i connected the connector to the header of J4, note that the holes on the other side of the connector are not being used by any SIL pins. The cable tends to put force on j2, but it doesnt really bother me, saves me removing the DIL connector and crimping a SIL connector. So then i made a new pinout diagram for the IC and connector, to make it easier to see which pins need to be soldered: The wireless veroboard strikes again! I soldered an IC socket to it, to make the IC removable (an obsession i seem to have. I even tried using a SIL socket for the cables but it was just too big to fit in, so ended up solering the wires directly to the SIL header instead. (I should of just soldered them straight to the PCB first time.) ..... and ended up with a funky and compact pcb. The Bankstick housing i bought was from Maplin is made of chrome(couldnt resist the look), and i always worried that chrome may be conductive since buying it, so i tested it out with my multimeter and yep, you guessed it, it is indeed so something had to be done..... Smash TV's Magic Pink Packagingâ„¢ to the rescue, to prevent those nasty shorts! Buy now!!!! and for a limited time only, recieve free pink packaging which will insulate your bankstick, with every purchase from SmashTV! ;) Then it was time to upload a patch bank to the Bankstick. It took me a while to find out, but the V2 patches can be found in the MB-SID firmware ZIP file, and theyre inside a preset folder. So i fired up the SID Editor and the Vintage V2 bank transferred perfectly. Theres some cool patches in there, my favourite is the "Techno 5th" preset, so thank you whoever contributed that one. :) Heres a quick little riff i sequenced with it: http://www.divshare.com/download/8280540-5f5 The SID Chip is more powerful than i realised, i only realised lately that each Oscillator has its own ADSR envelope, and that you can select which channels are sent the Filter,(you can hear me cycle through them towards the end of the mp3) every other synth ive known besides modulars just send all Oscillators to the filter. Ive had great fun playing with it so far, :) but mine isnt perfect, im having issues with the drum engine presets, which ill address in my next post soon. Thanks again to all involved!

Awesome! And its getting about 100,000 views per day too. The rotating cube blew me away.

Oh and: http://www.midibox.org/forum/index.php/topic,10928.msg84521.html :)

4 of these for 99p + shipping: and finally i think i *may* have found the perfect feedback pot knobs for the mb-6582: 8 for $9.99 incl shipping from HKS For some reason i think beefy knobs will suit the feedback pots more, because of the beefy sound they produce!

I'm currently trying to decide which Feedback knobs to buy for my MBSid & MB-6582 to be. Bendables have great UK prices on ebay, you can get 50 of these for only £8.49 + shipping :o I'm thinking either red on black for the mb-6582, or plain black, or their moog knobs are cheap as chips also, and come in 2 different diameters: only £3.25 for 5! -------------------------------------------------------------------------------------------------- Circuit Electronics Circuit Bending has awesome prices in the UK also, they say you will never pay over £1.50 for UK shipping, and £2.25 worldwide - No matter what the quantity! 10 of these for just £2.79 + shipping. 7 Of these for £2.25 + shipping, and theyre soft touch.

Just make sure not to accept any returns from him, with a username like that, god knows what could happen..... ;) (and yes, i did go all to the trouble of downloading that episode and converting it!)

POIDH! :P

I can has? :D I wouldnt mind both actually, i can use the mb-seq one for my 2x40 MBSid Display.

The images are in this quote of the finished box - HOWEVER. THeres a possibly malicious script, so be careful.

Surely one user has a few to many. If you dont want a huge bunch it would be worth putting a wanted thread up in the fleamarket. I think i might do the same for when i start builting the mb-6852.

You love the knobs! ;)

Yep. I was a bit worried too because of PWM and MD being labeled as CLK and SC on the sid module, but i just assumed they were and connected it up regardless. The first cable i used caused garbage on the lcd but i got sid playback! I used a better cable and then everything worked perfect. So essentially this is how to connect it: CORE SID J10 J2 ---- ---- MD ----> SC SO ----> SO MU ----> MU RC ----> RC CLK ----> CLK SC ---> (not connected) Vd ----> (not connected) Vs ----> (not connected)

If i do damage the pads i just realised that theres pads on both sides, so i could always solder standard resistors on the opposite side of the board. And nebula thanks a lot for the walkthrough, ill try it later. And thanks for the optrex display too! ;) Its working perfect and I really like it!
