I'm just about to pick up one of these white monsters but I'm wondering about the build quality.
On the unit I tested, the volume encoder felt a little wobbly, the rest of them were very solid.
I suspect that the volume encoder is fastened by its solder legs and not the metal base.
Did you experience anything like this Artesia? or were you just eager to get inside the box? ;-)

I followed the optimized PSU schematic for my 1Core+2SID's and it works fine here. There are some older schematics that contradict this one but If you are building a V2 SID then stay on the V2 page as much as possible and you should be ok. At least that is what I did ;-)

Ok, three more buttons connected. The simple control panel is now ready for testing.
And wow! :o
I still don't completely understand the little monster but I guess I need more practice.
I mean, my evolver wasn't completely understandable the first week either ;-)
I really understand that you might want the big control surface for this synth.
Now I need to get it into a box!

If still possible I'd be interested in
30 3FTL6 "Quiet" (or at least 6 if only breadcrumbs are left ;-) )
30 1S11.16.0 (Clear cylindrical)
30 1D.16 (Translucent white)
My Sid need to get pimped 8)

Nah, I think you will have to find another source of midisport 8x8, this one is welded to my rack ;)
Besides, I will need it for future projects (SwinSID, FM-box, MFOS synth, and what to do with my other 8 SID chips? ;-) )
I dont' know how many there are on ebay nowadays but I got my midisport dirt cheap (like 40 or 50 Euro ). But I found it when the "vsti have replaced hardware" craze was all over. Good for me 8)
Now I need more buttons ( I was cheap and bought only 6... Silly me... )

Ok, I got my Midi sorted now but my LCD seem to have stopped working.
Solution to my problem? RTFM! :-[
I had my midi connections all wrong. I completely forgot that there is a right mouse menu to connect stuff with.
+1 Stryd
-1 LCD Snebenan.
I'm embarrassed... And miss my LCD... :'(
Edit:
I just tried my other LCD as well. No Show.
Uploaded the Srio inter connect test again and the LCD is back working. And so is the first one as well. Hmm I'll try to reload the SID app.
Ok, LCD working again.

Well it was only Mios studio that locked up. The second time it happened I was able to kill it fromt he Application manager. It did take a while to die though, I bet it's the Java runtime that is slowing it down.

I'd be suprised to find my PC or midi being dodgy, Java maybe.
I tried with both my midi interfaces. Midisport 8x8 and the one built into my EMU 1616m. ( I do have a Delta 1010lt and midex 3:1 as well if I need to test others)
I also tried different ports on the midisport and different cables.
I would rather suspect a some dodgy soldering on my core, but testing will tell.
I will check my soldering, the go through the midi faq and then hopefully i have something that is working.

Ok, another update:
Short version: Yay! 8)
Long version:
Ok, I felt brave after that one and decided to give my Din another try.
I read on the Wiki that it may be a good Idea to hook up you encoders and then try to figure out what encoder whent where using this app: " ain64_din128_dout128_v2_0.zip".
Well for me that ended up with a constantly rebooting system.
Ok, I'll just upload Srio or the SID app again and get back to a stable place.
And that would not work. Mios studio hung and my computer would not reboot.
I had to do a hard reset on it.
But after trying a second and third time, (one hand on the power switch and the other on the mouse to start uploading the app) it uploaded correct and started working again.
And.....Tada... now my encoder on the DIN works!!! 8)
bugfight was right, I had the DIN4X connected wrong. I assumed that that the two columns of pins on J1 were symmetrical. And they are definitly not!
And now forward towards the mini control panel. YAY! ;D
//Peter

Edit. I couldn't wait ;-)
All measurements on Core J9 between Vs and the other pins on J9. (No DIN connected, only LCD)
D0 test
RC Sc SI Vd (Vs)
0 0 5 5 -
SC test
RC Sc SI Vd (Vs)
0 5 5 5 -
RC test
RC Sc SI Vd (Vs)
5 0 5 5 -
I still don't like that SI is on a constant 5V but since there is no SI mode in the testing app maybe it is ok? or should I measure SO on J8 instead?
//Peter

Hi bugfight,
When I look at the Core schematic at Smash http://www.avishowtech.com/mbhp/mbhp_coreR4d.html
This is the pins I measured on the core.
RC Sc SI Vd Vs
these pins connect to to following on the DIN4X
RC Sc SO Vd Vs.
So SI on the core is connected to the SO on the DIN and should have the same voltage right?
During my first measurements I measured on the DIN module but to be shure I disconnected the DIN and did a second measurement on the CORE directly but didn't update my debug value table so therefore the SI/SO confusion.
Makes sense? Or Should I go to bed without supper and do my homework again?
//Peter

Yep, DIY is very addictive.
Especially when there is a nice place like this to fall back upon when you get into trouble :-*
I will have a look at the MBHP Burner, Mike is selling it as a kit so maybe I will order one of those. And put a ZIF socket on it.
And if that doesn't work then I will probably need a new PIC and will have to order from Smash (I'm using the 18F4685)
//Peter

Ok, after discussing the problem with bugfight on the chat the conclusion is that I probably need to reburn my PIC :-(
The S0 leg is contantly putting out 5V and when pulling the PIC I found no other shorts.
My problem now is that I don't have a PIC burner so I'm wondering what is most cost effective,
Finding someone with a PIC-burner and mail the PIC there or to order a new preburned one from Smash?

Ok after uploading the SRIO interconnect App and doing some measurements I got the following on Core J9.
test DO:
RC Sc SI Vd (Vs)
0V 0V 5V 5V
test SC:
RC Sc SI Vd (Vs)
0V 5V 5V 5V
test RC:
RC Sc SI Vd (Vs)
5V 0V 5V 5V
I feel like I am missing something here.
1. The constant 5V on pin SI, should it be like that?
2. The only d0 pin I can find is on J15 for the LCD module, So where should I measure when doing the d0 test?

Awesome! Awesome! Awesome! 8)
Hmm, I guess the only way to top this is to make a 8X Sid box on nails with point to point wireing :-X
Did I say it is Awesome?
//Peter

Wow!
This is better looking than many commercial synths.
Every week I get blown away with the skilled and creative work displayed in the M-box of the week. Very inspiring and motivating.

yay!, got my SID's yesterday. 8)
Thanks Wilba!

Hi Wilba,
2 packs of four please 8)

Thanks Stryd,
I will probably not have time to try anything until after the weekend but I now have several things to try.
One at a time though... ;-)
(Btw, nice trouble shooting tips. No 7 is probably the one I try to learn people everyday....)
//Peter

Thanks for the tips Pascal,
I will try them after the weekend.

Ok some modest progress later.
My second Sid module is done and voltages checked ok (5,29V)
I also soldered up my DINX4 and hooked it up to the core.
But now I may have a problem.
I quickly solders up a encoder and two buttons and connected them to the DINX4.
Now, I'm using the DINX4 from Smash and this one have all output pins in 2x5 groups.
Fair enough I looked at the mbsid_v2_din_default and booted up the monster, but no matter how I turned and pushed my controllers notheing happended to the LCD.
Ok, Some searching later I learned to look into my asm files and see how the DIN Shit register pins are assigned.
And as far as I can understand it looks correct. But there could also be a problem with my LCD freezing or something so i won't see anything no matter what.
Any way, this is how I connected my encoder and buttons.
On J3
D0 - Enconder A
D1 - Enconder B
D2 - Select button
D3 - Menu button
Vs - Encoder C, Select button, Menu button
And in the asm
I have this
;; Function name SR# Pin# DIN_ENTRY CS_MENU_BUTTON_Dec, 1, 0 ; only valid if rotary encoder not assigned to these pins DIN_ENTRY CS_MENU_BUTTON_Inc, 1, 1 ; (see mios_tables.inc) and CS_MENU_USE_INCDEC_BUTTONS == 1 DIN_ENTRY CS_MENU_BUTTON_Exec, 1, 2 DIN_ENTRY CS_MENU_BUTTON_Sel1, 1, 7 DIN_ENTRY CS_MENU_BUTTON_Sel2, 1, 6 DIN_ENTRY CS_MENU_BUTTON_Sel3, 1, 5 DIN_ENTRY CS_MENU_BUTTON_Sel4, 1, 4 DIN_ENTRY CS_MENU_BUTTON_Sel5, 1, 3
I also trid to switch my A/B on the encoder just in case. ( But mixing these up will only make it scroll in the oposite direction right? )
Anyway, I'm puzzeled and open for suggestions. ???
My next step will be to see if I can make shure that my LCD is working as it should.
After that I can really know if my knobs are working or not.
Ok, time to go to bed.... :-\

Very Cool.
But how hard is it to find some SSM2044 chips? And what do they cost?
//Peter

Well, I left my thought to be defective unit on the shelf for nearly three years before this thread came along. (and to find it working perfectly just by changing cables... :-[ )
It took me two-three weeks to build, including the case (one hour here and there)
But after hooking it up and listening to some serious pumping I could not be more pleased. ;D
(it can probably be used transparently as well but that's no my cup of tea)
I finally understand why some people hang on to their hardware.
And I'm a big software fan, often preferring the SW alternative unless the HW sounds really good.( like a SID box) The Gssl is just instant gratification. 8)
I'm probably going to name mine "Make sound awesome!" ;D
(Btw, I'm using THAT2180LB VCA's)

Buh? there's only 5 there... I gogled and searched prodigy but no joy... Can you give me the lowdown?
It says, Release 2*5(6). I read that as 5 positions, or 6 is optional.
(page 2 in the pdf, above the release controller)
Have you got a gssl as well stryd?

And another one bites the wiki list ;)
I hope that shipping to Sweden won't be too expensive.
