No. sounds like you have a midi problem (a loop maybe) you need to get the core working with or without the sid plugged into it.
-
run the outline ULP and everything will be much clearer (looks like your also missing pads and holes also on your print, select those in LAYERS)
-
thats a typo, should be 25V
-
I disconnected the sid and tried to wire it up as shown in this diagram:
http://www.ucapps.de/mbhp/mbhp_sid_v2_core_interconnections.gif
Thats the wiring for the V3 board (i did the same thing)
Look here:
http://ucapps.de/mbhp_sid_old.html
The SIDs should be wired like in the GIF. The 5V line should come directly off of the optimized PSU to J2. Dont forget to pull the 10 mHz off of the sid module and replace it with a jumper to the middle pin of J7 (middle pin of J7 is CLK from the core and can be connected to one of the legs where the 10 mHz clock was on the sid board, its pretty self explanintory once you look at it)

What board? the light blue fields are usually wired to a plane (like GND)
-
do you have an LCD connected?
AFAIK u should be uploading the Main.hex file the Setup_6581 and setup_8580 are for the master/slaves
-
That should be it. the pic is requesting an upload. What bootloader are you running? To work with the current MIOS it will need to be 1.9.
Are you getting a bunch of square blocks on your LCD? (that should be the normal thing for a bootloader only PIC)
There are good instructions for updating the bootloader with the 1.9 MIOS. The basic sequence is update bootloader-> upload MIOS -> upload SID application
-
Well the keybed will need its own processer to deal with the midi so I would just wire the midi out fromt the controller directly to the core
-
I will be definitely making one. Cubase's midi device implementation is spectacular so writing one up should not be a big deal. There already is a VST plugin to control the midibox SID, btw (check the sticky)
-
I would just gut an old one or two octave midi controller and just use the keyboard portion then hardwire the midi out to the core
-
It states on the site that you can however your voltage regulator will get pretty hot
-
Thanks for the help, btw
What would be a indictation that there is a mismatch in impedance and what size steps should I increase the caps if there is?
-
So running it off the same 14 VDC rail as the sid modules is fine with the schematic as is?
-
I have been hunting for some easy mixers to sum the 4 audio outputs since I dont have 4 channels free on my console and came across this:
http://generalguitargadgets.com/diagrams/mixer_sc.gif
Now my question is, what would be the most efficient way to power it from the C64 PSU? The ins and outs of the TL072 are a little over my head so i am not sure whats acceptable for supply voltages and how that impacts the audio
-
Thank you gentlemen for completly derailing my thread :'(

Assumption is the mother of all f*ckups
lol, thats from a Steven Segal Movie IIRC

Greetings all.
Finally getting to the point of powering up my SID project and I have a couple (hopefully simple) questions that I could not find answers for at Ucapps:
I am using Tims previous rev SID and core boards based on the 6581 and the simple 1 sid PSU (mbhp_sid_c64_psu.pdf)
1> Are the connections for the above shematic OK for use with Tim's boards? I am assuming that all the pinouts are the same and anything not shown is left not connected
2> Where is pin one on J15? Its not marked so I am assuming it would be in the corner based on the orientation of the text
3> Any other tips would be greatly appreciated
Thanks!

Something is stopping power and lowering it to the half . .
in MIDIbox SID
Posted
on the core you need to remove voltage regulator (5V will be coming from the PSU) do (and short the pins)
