Hi, I have some MOS 6581 for sale. USD$26 each. Postage $5 worldwide (registered airmail / tracking number will be provided)

I have some 8580 for sale. They are $50 each. I have 6582A too, but they are not for sale :rolleyes:

I just found out that I can upload the patches from Mios Studio. I have successfully upload it to bank A. How do I upload it to Bank B C and D?

Hi, I 've just finished building a sammichSID. I have uploaded setup_sammich_sid.hex firmware and it restart and formatted all the bank sticks. I've downloaded Ctrlr patch editor, but I am not familiar with this software. How can I upload the default patches into the sammichSID? I've been keep looking into the Ctrlr software and I couldn't found any option to import the default patch file into the software. Anyone have any ideas what should I do to upload the default patches v2_vintage_bank.syx into the software?

Hi Wilba and pingosimon , Thanks for the replies. Is 652-PEC16-4220FN0024 the right part number? It looks like the pin is 90 degree with the shaft in the photo. Have you confirm this part can be use with the sammichSID? What about the old encoder? What model is it? Regards, VS

Hi, I have problem with the sammichSID Encoder, when I turn the knob there is no response. I couldn't change the patch by turning the knob. I want to buy a new encoder. Does all encoders works for replacement? I can't find any 16mm detented rotary encoder. Any suggestion? Regards, vs

Hi, I have problem uploading the firmware on the Sammich PIC. I think something is corrupted in there. I also bought a MB-6582 PCB with PIC long time ago. Can I use the MB-6582 's PIC on sammichSID ? For both bootloader and firmware of Sammich and MB-6582. Are they the same? Regards, vintagestar

Hi, My Sammich LCD backlight is not working. It is a high-power backlight LCD. I have already put a shunt in JBL in the “12V†position. I have also Put a shunt in JR4 to increase current. The backlight was working before. However, when I take it out and turn on the synth. The back-light is not working anymore. Is the LCD broken or there is some kind of bad soldering on the PCB? What should I check on the PCB to be able to find what cause the problem? Thanks Regards, vintagestar

Hi, I have finish building the sammichSID last week. Finally, I found out it's the USB <-> Midi cable's problem. I have install a sound blaster card in my computer and use that midi, the upload works finally. Anyway, I have put two MOS 6581 in the synth. However, there is several patches sound volume is quite low. Is the chip filter broken? P.S A016 Filtered Poly / A017 Filt Mono Pad / A022 Filtered B 6581 / A023 Filtered B 8580 / A044 Turntable / A048 Helicopters...etc I can hear them, but the sound volume is lower than other patches Regards, vintagestar

Hi, I bought a new 6N138 chip. I also ask someone who has a PIC programmer to burn the hex file for me. However, I don't really understand what to do after reading this http://www.ucapps.de/mios_bootstrap_experts.html . Anyway, I downloaded MIOS V1.9g and Bootloader V1.2 from here http://www.ucapps.de/mios/mios_v1_9g.zip . There is two hex file. Which one do I have to burn into the PIC? Under pic18f4685 directory, sub directory burner has " bootloader_v1_2b_pic18f4685.hex " . Sub directory has " mios_v1_9g_pic18f4685.hex " . Which file do I have to burn into the PIC18F4685 chip? Regards, vintagestar

Hi, Can you take a look if I put the 6N138 on the right direction? I put notch facing the right side before just like what the PCB show, but MIOS can't detect the bootloader at all. I put the IC notch facing the left side just like the photo shown here. Sometimes the MIOS can detect the bootloader but not stable, just like what I mention at the previous message. Regards, Sam

Sometimes the software can detect the bootloader, sometimes it doesn't. Even detect is sucessfull, the upload might have no response. Even upload is in progress, uploading speed is about 1% per minute, which mean it takes more than an hour to upload that hex file. After upload are completed, sammich doesn;t restart, screen is still blank.

Hi, Yes, I have two Sammich having the same uploading and booting problem. Regards, Sam

I just try to put the 6N138 IC the other way around. Sometimes the software can detect the bootloader. How come? I thought I saw the notch of the IC is on the right side? However, not every tinme success. After MIOS sutdio 2 detect the bootloader, I was trying to upload the hex file. However, sometimes it has no response. Sometimes it was working, but the upload take about one hour to complete. After an hour time of uploading, it show the upload was complete. I press the query button, the software still only detect the bootloader only. It can't detect the application. Also Sammich did not reboot, the Sammich LCD screen is still blank. Anyone knows why? Regards, Sam

I know, MIOS Studio 2 show that it couldn't found MIOS core and ask me to check Midi In and Out. I am sure the midi cable connects correctly. Again, I am sure the PCB are fine, my soldering is almost perfect!!! My midi cable problems? Don't forget I use the same cable and successfully upload the hex file to my first sammichSID.

Hi everyone, Thanks for all your replies. I have build another Sammich and download the Mios Studio 2. Still not working. I am sure there is no problem with my soldering and all the resistors and caps are solder at the right place. The voltage test is also ok too. Midi In and Out cable connect properly. I really think there is something wrong with the PIC. Actually, I have successfully build the very first Sammich about two months ago, and I use MIOS studio 1 to upload the hex file, everything goes fine. My friend are using it everyday. I don't know what goes wrong, I use the same software and same computer to upload te hex file on the second kit. Lots of people tell me just to reinstall the MIOS is ok. However, the main problem I really like to state again is "I can not boot up the Sammich". Normally you will see "READY" on the Sammich LCD when you turn the power on because the PIC has pre-installed bootloader. However, when I turn it on now, There is nothing on the LCD just like there is no PIC installed. How can I re-install MIOS into Sammich when I can't see the "READY" text on the screen? Why I think the PIC data are corrupted? because I thought I soldering something wrong on the second Sammich so I try to desolder one of the resistor and I accidently destroy two of the soldering pad and the nightmare start from there. After the upload is not success, the Sammich try to REBOOT Automatically but that "REBOOT" text just stay one the Sammich LCD screen for an hour. (it happens on both PIC I got). I have no choice but switch the Sammich off whilte the REBBOT text is still on the LCD. The screen just goes blank when I try to switch it on again. I am sure some of you might think I must solder something wrong on the second kit which cause this problem. Well, actually I just build another Sammich again and this time I am 100% sure all the connection is correct. I am sure there is nothing goes wrong on the PCB or any components I solder on it. Can someone please help what I should do? I took some photo when I use Mios Studio. Regards, Steve

Hi everyone, Today I got a new PIC, so I plug that into the socket and try again....ooooooooppppppsssss Same thing happen again. I think the PIC is dead now. Here is what I did today. 1./ I take out all the IC and check all the voltage is correct, and then I put the IC back and open Mios Studio. Configured midi In and Out 2./ I switch on the Sammich, I got a single upload request message in Windows IN, but I got that message in Windows OUT too...... that's weird. 3./ READY is on the LCD screen, I try to send some text message to the LCD, and it works, so I try to upload the sammich hex file and here the problem come : 4./ then....."MIOS Rebooting" on LCD screen freeze forever, after 30 mins waiting, I have no other option and turn it off 5./ Same as last time, the LCD screen goes black and I am not able to boot up the sammich again. Can someone please help. Regards, Sam

Hi Alex, I have installed the PIC but I get the same message on both midi in and out monitor. Is that normal? Regards, Sam

I can not boot up the MIOS Bootloader. After my first attempt installing the MIOS setup, I think something corrupt and and the end the Sammich LCD screen just show "MIOS Reboot" but the screen freeze like that. I turn off the Sammich and turn it on again. Now there is no text on the Sammich LCD screen. Can I still re-install MIOS again under this condition? Seems like something went wrong on the bootloader and I can not boot up the Sammich now.

Hi, This is the second sammichSID I am building. I am not able to upload the SID application. I think there is some error whilte uploading, and I am not able to boot up the application when I switch on the power. This is the steps that I mess it up : 1./ Initial testing with MIOS studio, I got correct upload request message in Midi IN window, LCD is "ready" but I am not able to send comand to the LCD 2./ I thought I solder the wrong resistor but I didn't. I desolder R4A(82k) but end up destroy the soldering pad, I resolder them on the other side of PCB. 3./ I finally found it is a careless stupid mistake, I forgot to put the 6N138 on IC2 socket, that's why LCD messsage couldn't be sent before. 4./ Both midi in and out wasn't working, I think there is something short on R4A (may be), I don't have a circuit diagram so I don't know where it links to. 5./ After a bit of clean up, both midi in and out is working under MIOS Studio, I get the right message in MIDI In screen and able to sent text to LCD. 6./ After everything is fix, I've tried to upload the firmware "MIOS Hex File Upload", I think first 10% went ok and then all became error after that. 7./ I saw some code end up error on the screen (some is ok at the beinging), and my sammichSID screen try to reboot MIOS 8./ Mios Reboot text just stay on the Sammich LCD screen forever, obviously the data went corrupted. What should I do now? Buy a burner to burn a new PIC? Where R4A links to, I am very worry something goes wrong there which make the firmware upload unsucessfull. Regards, vintagestars

Oh, I forgot to mention. I fix the problem with my desktop which is Windows XP. I think they don't work in Vista, Midi Yote is not compatible with Window Vista.

Thanks!

Hi, Just wondering what is the different between 6581 and 8580? I mean the way they sound? I just load all 128 preset patches in the sammichSID. I install MOS 6581 in the sammichSID. Do I get all 128 patches sounds the same as the mos 8580 and 6582A ? P.S The 6581 chips gets pretty hot. Is it normal? I have test the socket is about 12.13V. How come the chip gets kind of hot? Is this going to kill the MOS chip if I use it for a few hours? Regards, vintagestar

Problem fixed. Need to use MidiTrix and Midi Yoke before I start the Midi SID editor. Thanks

Thanks. Do I need to do any setup on the sammichSID before I do the transmit? I don't know if my midi interface is muti-client capable or not. It is not a sound card. It is those USB <-> Midi convertor cable with a build-in device. I've load the preset sound patch into "Midibox SID Editor" and then I choose "Transmit patch to memory" and it pops out saying that the MidiBox SID not responding and ask me to check the connection. I am pretty sure my midi in and out is working, because I am able to use MIOS Studio to upload the firmware.
