Yes, it will work without any additional circurity.
But if you don’t see the empty bar line, then propably some connections are wrong - you have to double check this. And I hope that a wrong connection didn’t destory the LCD, this can happen very fast!
Maybe the contrast pot of the other core modules is not adjusted? However, please don’t try this, check the wiring first!
Best Regards, Thorsten.
I have soldered like a dog…
I removed our nice 16 pin connector and used plain wires. I get the same result, just a quick flash in lcd and continuous backlight.
However, because my frustration kept growing and I was almost sure that the whole synth is flawed, I decised to upload sid-application to my core. I even connected headphones to audio out… Good thing I did, because it works!!! Oh boy! My sid is alive!!
Thorsten, that cheap pulse… I thank thee!
LCD seems faulty. The reaction has been the same from beginning, never even changed the wiring, just triple-checked and proved it right. It could be broken from the beginning. Too bad I ordered it from Germany, as it is hard to return. I try to get one from somewhere just to test if I can get it to work.
I managed to program all PICs and change device_ids to proper values. After tracking down a cold wire, I got ‘link’-button to work and got sound from 3 of 4 sids. One of them keeps this continuous high noise. i changed the sid, but the flaw remains.
So, only real clue I have is that high pitch sound that SID #3 sends. Well, I am sure I get it sorted out. -update: fixed, now 4/4 sids are running nicely!!!
Just browsing the net to find my midi-keyboard solution. It seems that small keyboards are USB-only, which isn’t nice. My intention is to build complete synth, with keyboard. I only have lenght of 45 cm for keyboard. Does anyone has good, small products that carry midi-port too?
Seems rather ridiculous that there is not small midi-products. Maybe some old Casio might do the trick, but they seem a bit rare.
Keep an eye out on eBay for crappy old keyboards that you can rip to bits… I see a good cheap casio POS for less than $30 about 5 times a week. I scored a nice 49 key MIDIMan controller for $7

True true!
Maybe I can make a built-in keyboard after all then!! In my case there is around 45 cm space for keyboard. I would be ace if I wouldnt need a separate controller.
Is it difficult to save working midi out and keys from synth?
At the moment I try to figure if it is possible to add midi-out jack into M-Audio eKeys that is just perfect for my needs, minus midi, of course :-\

Nah it’s a piece of cake, you’re just re-casing it really, no electronic alterations necessary…
The signal is probably generated straight from the input pins of the chip to USB, so it’s unlikely that there’s a non-USB midi signal anywhere near it… You’re probably after a USB-MIDI Interface, not sure if the MBHP USB module would be suitable?

I think it is easier to find some small used midi synth and make most of it. It is just so frustrating to know that there is a perfect keyboard for 49 euros, but only without midi. Is it possible to make midi keyboard ot of synth that does not have midi out? I mean, isn’t most of the synths still controlled internally via midi?
Gotta keep searching or pick another case that can hold a bit longer keyboard.
