Everything works fine now, i checked the sid board with the interconnection_test and noticed that both the 74HC595 where dead. Now it's time to build the control surface! ;D a couple of questions: 1- Is this PLED display ( http://www.elettroshop.it/files/prodotti/download/deltaopto/PDC1602M03.pdf ) supposed to work with the core_module or it does need more driving strength? It's HD44780 compatible and needs a supply current of 0.35(typical) to 0.60(max) mA. Do I need to make any improvement on the psu (I'm using the c64 optimised psu) in order to drive 4 core + 4 sid + full cs + PLED display? 2 - Is it possible to have mixed sid types in the chain (eg. 2x8580 + 2x6501) without modyfing the psu or the best noise-proof solution is to have a psu for each sid type? thanks! Shaduz

I made the optimised psu and now everything seems ok but i have no sounds from the sid... when i use JSyinthLib i hear clicks when turning the pots or sending a "Play patch", but no sounds. Anyone has any ideas? What checks can i do? :-\ I'm using a core v2 and a 8580 sid.

ok so there are two 7809: one on the sid board and one on the psu, right?

In the optimized psu: the 7809 and the capacitors are those stuffed into the sid board? or shoud i remove them from the sid board? what about the 2200uF and 100nF capacitors? Are them on the core board or external? ???

I just finished the SID and CORE v2 modules. The core is working and i succesfully uploaded the os and the application, but the sid outputs only high volume noise. The voltages are ok, but i don't know if i connected the psu in the right way: the c64 psu has a 5v DC output and a 9V AC output, i hooked up the 5v dc into the core (without the 7805 regulator) and the 9V AC into the sid module. Do i miss any connection? should i also connect the 5vdc to the sid module? I'm using a 8580 sid. hope someone can help... Shaduz

i just got 3 x PCM2902 and 3 x OPA2353UA for free... ;D they can be ordered as samples from burr-brown/ti webpage (http://www.burr-brown.com) ;) the remaining stuff needed to build the usb interface should be easy to find, now i just miss the optical receiver/transmitter modules :-/ greetz

Thanks so much Thorsten !!! You always have a good answer... ;) Greetings [shaduz]

Hi all, anyone knows if it's possible to use 2 of the midiboxPlus buttons as "Program Change UP" and "Program Change DOWN"? I can assign a known program number to a button, but it would be more useful to increase/decrease the current patch number with only 2 buttons... hope some1 can help ;D Greetings [shaduz]

well... the edrum project is cool, but i'd like to integrate everything in my midibox. Do you think that the analog interface of the edrum would work with the midibox? Probably it would be necessary to modify the firmware of the midibox64 to handle events like a hit on a piezo...

hi, how do i process the signal from a piezo to connect it instead of one pot or fader? thx :)
