Lucky me. I ordered the case from PacTec directly. I don't remember what the screws looked like exactly but I think you are pretty close.

Didn't your case come with those screws? Mine did.

Wow! "Transpose" is really good!

I used only one layer but glued it right to the panel with cyan acrylate glue.

I used .100 spacign cable. I got it from Farnell: http://uk.farnell.com/amphenol-spectra-strip/135-2607-312/ribbon-cable-3c-12-core-per-m/dp/1301034?_requestid=426716

I cut a piece of CD jewel case. Judging by how jewel cases usually behave, it might be a bit fragile, but it is pretty well protected and looks good.

There are some pinctures of my build here http://www.midibox.org/forum/index.php/topic,13432.msg115675.html#msg115675 if you are interested.

Is your first bankstick a 24LC512?

I liked the idea of puting the J-B Weld on the screw heads instead of on the panel. Didn't think of that one. Puting it on the spacers wouldn't be too clever though ;)

I mixed it in a small plastic container, about 10x10mm then i sucked it "back way" into the syringe through the tip. I had to do it about ten times every time sucking until there was air coming into the syringe so that I could press the handle back and do the process again, every time gathering more J-B Weld in the syringe. Hope this makes sence. I lack the words a bit...

So, will you use this to control the level of the synthesizer section and in that case, how, or will you use the master level midi message externally in some way? The 9090 cannot make any use of the level midi message, right?

The reason I ask is that in your layout drafts, there is no master level in the sythesizer section but one in the sequencer section. Thought you might have moved it there.

So, how do you plan to implement the master out control on the control surface? Will it work with the 9090 or is it just for midi out from the sequencer? You will not fit the dual gang pot of the 9090 main level on that spot, will you?

I think I got some of these 8-pin female housings (I guess you mean the housings for the crimp connectors and not the headers you solder to the board) that I bought by accident from Smash TV. It turned out I didn't need them. If you still need them, I could send them over. I think I got eight of them.

I used a syringe without needle that I got from my girlfriend that work in the hospital. Worked really well. The only problem was to suck the sticky J-B Weld into the syringe, but it was easier than expected.

I have the standard GM5 PCB (one in and one out) for you if you want it with flexis chip. You can have it for the price of the postage which should be less than £2. EDIT: I have just the PCB for "sale". No chip.

I have one board, but no chip. Tell me if you are interested.

I figured it out. The first 24LC512 was faulty. It works like a 24LC256 except it has 24LC512 printed on it. I replaced it and now it works fine. The other issue seems to be when I start off from an <empty> patch. If I initialize it to the "Lead patch" before tweaking my own patch there seems to be no problem editing patch name when saving it. Here are some pictures. No supprises, just a very nice synth! Thank you again Wilba.

But I can select nothing but these special characters. I cycle through like 10-15 of them and that's all I can select. This happens some times. I haven't been experimenting enough to find a pattern on when this happens. Regardning the bankstick chips, I have seven 24LC512 and one 24LC256. To make sure the single 24LC256 was inserted in the right socket I removed it and concluded that I could not save more than one ensamble any more. I think that would indicate that the 24LC256 chip is in the ensambles socket and that all patch sockets are stuffed with 24LC512:s. Thanks for taking your time.

I removed the one 256 bankstick and that resulted in that I couldnt save more than one ensamble so it was obviously placed in the right socket. There must be something strange about this. When I try to save a patch in >64 slot of the first bankstick it says "not possible". It seems it cannot access the higher 64 slots. Maybe this is related to the other error? Maybe one of the pins of the memmory chip is badly soldered... I realize this keeps my post count up, but if someone recognizes this error, I'd be glad to do the right thig at once...

The banksticks seem to work fine and I manage to upload the syx file from sysex librarian. When I go to preset 65 in bank A it says no bankstick so I guess I have swaped the ensamble bankstick with bank A. Will check when I have time. When I save a patch I can sometimes enter text with the encoder but sometimes i can just choose between some symbols and numbers with inverted pixels (the pixels of the number itself are not active but the pixels surounding it are lit forming a square). Is this a feature I don't understand or is it some kind of error?

I found and corrected the problem. Kind of embarrassing... I had turned every second resistor network the wrong way. Had to cut them to pieces and desolder them one pin at a time. That should teach me to be vey careful with non socketed multi leaded components. Good thing I had some replacements in my wilba-seqencer parts box. Now the encoders work fine! Thanks to you who helped me out. The sceond issue. After uploading a .syx file of presets, all I should do is to twist the menu encoder to brows through the presets, right?

I have sourced all the component myself. They might be no good. Good point, will check it out. There should be 10k between the marked pin and the other ones respecively, right? I've been looking for this, and I think it seems right from shift register to encoder... Anyway I will check it out again if the resistor networks seem fine. I am using the ones from Voti. Do you know if anybody actually used them in a build before? Thanks

I double checked that. Now I found some traces though! The voltage on the non gounded pins of the encoder should be 5V when not closed, right? I meassured 0.44V on a failing encoder. I followed the signal path all the way to the shift register, still 0.44V. Then I was interupted and had to quit trouble shooting. Will hopefully continue today. Also I found out that the encoders connected via pad 00 and 01 of JD1-JD4 are most prone to fail followed by the ones connected via 02 and 03...

No worries, the leds I found at work was good enough to use, so I'm glad you could inherit the thread m00dawg :D
