How much money are you asking for it? And where are you located?

Ok, I have decided to buy a new pic. I have burned the bootloader, mios and sid app and now everything works. Looks like the problem was in the pic.

I have the same problem too but not with the sammichSID, I have build the stereo setup myself. And my right channel is dead from the beginning. I have burn the bootloader, mios and the application again, didn't help. I think there is something wrong with the pin 27 of the pic (J14). When I replace connections between pin 27 and 24 of the pic the left one is not working but he right does work I am going to buy another pic and try.

Since nobody replied me I did a little research and stumble upon this post I was not in the sid forum but in testing/troubleshooting so I didn't see it before. Is it possible that the problem is with the burner? Mike burned it. I think that he knows what is he doing. I have uploaded the mios again and the sid app again and the problem is still here. Other thing, I played with the sid a little, and the sid is not responding to keyboard like it should. On bass patch it is all fine, but on any poly patch, when I press a chord, the first time it only plays one note, second time three notes. I still don't have control surface so I don't know is the sequencer or the arp on a patch, maybe is that. Thank you

Hi, I tried to build a twinsid from yodabe and I had problems with it. This is a link to the previous post: Now I have etched my own board and I am having problems with the Right channel. Left one is working fine. I have tested the right channel (connected with the j14 of the core module (pin 27 of the pic) with the testtone app and it works. It has passed all the tests with the interconnection_test_v2 except the pin8 of the sid chip, it's not giving me the right voltage. It should be 0V when I press the Key on midi controller but the voltage is changing between 0.3V-0.9V It should be 5V when I don't press a key but it stays the between 0.3V-0.9V The pin 8 is connected to j14 of the core module (pin 27 of the pic) and I have tested the solder joints, it is all fine. There is no shorts or anything. I did another test and connected the pin 8 of the right sid module with the pin 24 of the core module and it works. What could be the problem? I have attached my board. stereo sid SILK 01.pdf This guy seems to have the same problem but his worked for a while Thank you Kike

I have grounded the input pins and still nothing. Going to etch another board, this is not working. But this time I will not go with twinsid.

No, i didn't tied them to the ground. How did I forget that. I will try tonight and see what is going to happen

Hi Janis Thanks for the help. I have checked everything. I am using 8580 chips, put a 22nf caps on the pins1/2 and 3/4. Put a pullup resistor on the lcd Voltages are fine, 9V and 5V. I bypassed power from the TWINSID board and build power supply that was suggested by Thorsten. I have tried yesterday the socket that worked the first time and now I hear very high noise on the output, SID works Noise changes when using midi keyboard in mios studio. It is some kind of flickering noise. I am going to etch another board, going mad with this one. Regards Kike

Hi I am trying to build a SIDv2, actually a TWINSID from yodabe. I have build only a main board for now, and the sid worked, when I tried the sid tomorrow there was no sound. So I have tried the testtone app to find out Is there a problem with the output amp. I have connected the 8 pin and the 27 pin and there is no sound but when i touch the wire with my hand there is a sound, What? Strange. Can someone give me an advice what to do, what to replace, what to check? I have put the sid to other socket on the board and it works like a charm. this is the link of the project: http://www.midibox.org/dokuwiki/doku.php?id=mb-twinsid By the way, the left sid on the main board is not working Thanks, Kike

The problem is solved. I did it. No need for help.

Hi everybody! I am building a 808 with microlarge pcbs and mb808seq I have uploaded the default mb808 hex file and everything works, but I need to replace some dout triggers and enable the swingpot. I have changed the asm files to do that but I don't know how to compile it to hex. I have read the wiki page about that, installed needed apps, struggle it for hours but i didn't manage it to work. Even asked a friend to do that for me, he also didn't succeed. Can someone see if I have done it right in the asm file and compile that to hex, please?! I have attached the asm file setup_808_kike setup.asm I have changed triggers to shift registers 1 and 4, added external triggers, and enable the swing pot. I want - bd to trigger from pin7 of shift register 1 - sd to trigger from pin6 of shift register 1 - lt to trigger from pin5 of shift register 1 - mt to trigger from pin4 of shift register 1 - ht to trigger from pin3 of shift register 1 - cp to trigger from pin2 of shift register 1 - ma to trigger from pin1 of shift register 1 - rs to trigger from pin0 of shift register 1 - cb to trigger from pin7 of shift register 4 - cy to trigger from pin6 of shift register 4 - oh to trigger from pin5 of shift register 4 - ch to trigger from pin4 of shift register 4 - ext1 to trigger from pin3 of shift register 4 - ext2 to trigger from pin2 of shift register 4 - ext3 to trigger from pin1 of shift register 4 - acc to trigger from pin0 of shift register 4 - and enable the swingpot I have uploaded the mb808 app with swing pot but the lcd doesn't show changes of the swingpot. Is that OK or is it something wrong with the swingpot? I can't test it yet because the microlarge pcbs are in soldering status.

Thanks Thorsten for your trouble. I don't know how to work in perl though. I am going to leave it this way, configure midi inputs and outputs in my daw, and that's that. Best regards Kike

i have try more things I have downloaded sysex box and try to request sysex dump MIOS program memory - It receives sysex dump, bytes 22496, blocks 19 MidiBox 64 bank - it don't receives sysex dump MidiBox 64 Patch - It don't receives sysex dump

I have build PIC18F Query detects midibox It says: Operating System: MIOS8 Board: MBHP_CORE or similar Core Family: PIC18F Application is up & running! when i send sysex it sends it, it goes to 100% But nothing change. When I pres "learn pot" in midibox editor, and when i move pots on midibox, pots move on virtual midibox, and I see changes in pot properties. When i press "learn button" in midibox editor, and when I press a button, virtual midibox don't show that I pressed the button but I see the changes in button properties. When i send sysex file to midibox, should i see any change on the lcd. I don't have banksticks. I am going to try once more, if nothing, I am going to keep it like it is

I have tryed to configure my midibox with the midibox editor but it did'nt worked. I have changed the button type to controller, send sysex to midibox but nothing happend. Everyrhing is the same. I have stored the sysex file to disk and try to upload it with mios studio and again nothing. Mios studio is receiveing midi from the midibox, everything seems to be in order. What now?
