  1. Not sure if this is not doable at all, or if it is not worth to do :) Got no time to go in the ASM code of the OS, but if that is what is required, I can do that no problem.
  2. Been looking at the manual for a while but can't get this to work. When I turn on the device, it sets itself to midi CH1; which will be global for all the presets. I would like at boot to have CH5 set for all the patches. How can I do that?
  3. Thanks! I was wondering why there was also a couple of banks that are not usable. And totally forgot about the bank reserved for the ensemble. Thanks!
  4. I am troubleshooting an issue on my sammichSID; basically I see that all the 24LC512 memory chips are installed; there are 5 of them. When using the SS, I can see bank A, B, C and D, but E, F and G give me the "no bank" message on display. I am curious how does the memory on the SS works, with these chips. Is each chip hosting a bank? In which case I should see banks A through E; but the last bank seems to be D. Do I have to initialize again the chips, or maybe some went bad? Thanks
  5. Found the issue; I had a newer version of CTRL; so the panel won't work. Downloaded a version from few years ago and it works fine. Cheers!
  6. I have found the CTRL panel for the sammichSID; which seems to work for wave shapes and other controls; but if I press buttons like the one to init a patch or to read the patch from the device, it just hang. I see the LED on my interface showing midi traffic but it never stops, it goes on and on. I just started with CTRL so I can't just look at the problem and figure this out, so I wonder if someone can give me some pointers about what is going on and why. Seems that the panel wasn't updated for quite a while, although same goes for the sammichSID, so I wonder if this is somehting that ca
  7. Hi Krizz, not sure who this Paolo is, but I assume you got the wrong person :) Indeed I am going for the 8580 too; got 2 more SID chips since I am building also another midibox on top of the sammichSID ;)
  8. Brilliant, thanks for clarifying things!
  9. Thanks Thorsten, Tried as you mention, but somehow that ABW parameter does nothing fundamentally. I tried to load the init patch and the "techno PWM" and the background note that continue to play is still there,although I lose the glide when it is on. I can still hear the background play on any patch I tried, even turning on ABW. One interesting thing is that there is a GSA parameter, that is also used to solve the ADSR bug, from what the manual says, and when I enable that; the outcome is like if I had a "hold"; so the note continue to play even after I release the key, at full volu
  10. Hi, Just finished to make a sammichSID; using 2x6581 original SID from 1982 (not sure the revision; I would assume R2?) sourced from my old C64 and the second was from internet. Everything seems to work fine; although I noticed that there is a very prominent issue: the clearGate bit does not seem to be set when the note off is send; so while the sound is not that pronounced, you can see from the oscilloscope and hear from the speaker, that the VCO are still up and running. I have no idea what the problem is, since I am using MIOS, I didn't write the code myself. Searching the FA
  11. Nice pictures! Those will come handy to get a comparison when soldering the components. Did you buy the kit including all the parts included? Would be nice to have an updated bill of parts for that kit, I just ordered the parts for the core and SID modules, not for the MB-6582 PCBs yet :)
  12. Thanks for the clarification. In the end being a DIY project, I understand everyone can make it as they like :) What is routing matrix adding to the overall experience? Maybe it is more for live usage? I am planning to tuck the device under the table or somewhere around and use it as sound module mainly, so the lack of extra controllers or even a screen is not bothering me (for now) :) So the issue is just noise? The manual seems to mention ghosting, when a note is pressed and released; which to me sound like a pretty big problem. I can do filters; so if that is all is needed that should
  13. Thanks; I read the manual but it is not a step by step manual, so it is more of a guideline about how to do things, and there are no reference to pre-made PCB ; that's why I was asking (there is a broken link referring to a kit, that's all I was able to find on the manual). Since I want to try all solutions, I did order the PCBs AND got the sammichSID kit; hopefully it will arrive soon, since I paid for expedite shipping. I have 2 6581 so I can use one for each project and see which one works best for me; got all the components monday, so I can do all 3 implementations at this point and s
  14. Thanks for the clarifications! So it is fundamentally a core with 2 SID modules then? I looked around and the prices for the few on the market are insanely high. The other alternative is ebay kits; which I assume are not "original", if the user didn't release kits anymore and he is not selling them from what I can tell. If it was in the 100-150 USD ballpark I may consider it; but I see that ModularAddict sell the PCB already, so that is a more practical way to get started I think. Good point on the SID not being producing the same sound; I was curious why would someone use 2 in stereo, bu
  15. I am a beginner too and finally got the plan to build a simple setup with just the core and the SID module, and like others, I also found myself struggling to find step by step instructions that show how to do things; but the nice part is that the forum is pretty active and people are super helpful! If someone has an updated bill of materials for the various modules, that would be awesome to have! Also I am not sure about PCBs... is ModularAddict selling PCBs for the different modules? I found one PCB that say 'SID synth main PCB", although it is quite large and does not look like th
