  1. Hi Phatline thanks for the pointers. I meant the Midi Monitor of the Sequencer itself (Menu-Midi-Midi Monitor). The good news is I got it working. I switched the ICs and made the cables a good bit shorter. I don't know what it was in the end, but my money is on the cable. cheers 6040
  2. Hi all, I finally put together my Midibox and most of it seems to work, but I am stuck on the Midi In and Outs. I followed the build guide of Modular experiments (http://niroke.blogspot.com/2017/07/an-unofficial-build-guide-for-midibox.html) The four IIc Midi Outputs work. The other 4 In/Outs do not. When I power it on the lights on both MBHP_MIDI_IO light up briefly. When I connect a keyboard to an In and press a key the light on that port goes on as well. In the Midi Monitor I do not see any Midi Ins, should they show up? When selecting any out on those boards it does not play. It does however play on the IIcs. I had the nose on the cable from J11E to the MBHP_MIDI_IO on the wrong side meaning the 5V went to the wrong place. I hope this did not damage anything. Any help for further troubleshooting? cheers 6040
  3. Thanks a million Phatline, that the "Si" to "So" part is just what I needed. I guess it is time for glasses finally :) So if solder this J8/9 "Pfostenbuchse" on the underside of the PCB the direction is reversed meaning the nose looks to the left? (Instead of to the right as in your picture). cheers 6040
  4. Hi all, I am following Hawkeye's build guide and am wondering about how to crimp the cables for connecting the pcbs together. If I crimp a cable according to this picture S0 and S1 are switched. Shouldn't this be a 1:1 connection? Unfortunately on the Wilba CS board there is no marking on how to position the "Pfostenbuchse" WSL10G. Looking through all the photos of the different modules it looks like the cutout on the "Pfostenbuchse" WSL10G is where S1 should be, correct? Should the connection be 1:1 or should S0 go to S1 instead? cheers 6040
  5. Thanks Keeze for pointing me in the right direction. I did some reading an it looks super easy: J16 ENC28J60 Vd VCC Vs GND SI SO SO SI SC SCK RC2 CS
  6. Hi I am in the research phase to build one of these beauties. I want to add an Ethernet port for the BLM emulator. Since the LPCXPRESSO is unavailable I believe I have to go with the MBHP_CORE_STM32F4. Has anybody used the MBHP_ETH sucessfully with this core? Is there a pcb/gerber for the MBHP_ETH available to buy? Cheers 6040

    Sid Ch Select

    Thanks is the SwinSID Ultimate the only one to support this? It seems to be unavailable.

    Thanks a bunch, got it now. One last question if you do not mind. The feedback pots only work on real chips and not on the swinsids, correct? Or is there a special version of the swinsid that supports this?

    Sid Ch Select

    Could you explain a bit more how I would add a noise gate? I probably should not have mixed two issues into one thread. What is the purpose of the Sid Ch Select (L/R)? I cannot hear any difference, not even on stereo patches. Thanks 60/40

    Thanks for getting back to me. I tried the three working 6581 chips I have in Sid Socket 1 alone and they all have that issue. If I put the Swinsid or 8580 in that same socket it is gone. I found this on the ucapps site: After a sound has been played, you can sometimes still hear it in the background: thats also an known issue with the VCA of the SID chip. This seems to happen to me but without playing anything just selecting a patch. Is there anything that can be done with settings to get rid of this?

    Hi all I am surely no expert in soldering and I probably did something wrong. If someone could tell me what happens on your midibox if you select the sid channels (L/R), that would really help. I made a small video of the 6581 issue https://streamable.com/nbp45w There is no midi connection I am just flicking through the presets of the bank A. The sound stays on until I select another preset and it is especially noticeable on the Zelda Sounds. This only happens on the 6581, not on the Swinsid, neither the 8580. I moved the 6581 around to a different pic and the problem stays with it. Any thoughts? Thanks 60/40

    Sid Ch Select

    Hi all, I finally got my hands on some working sids for my MB-6582 and have been playing around with it. I gave up on hunting down ebay chips as most of them are not working. I got two already that half work for lead sounds but the rest does not work. Anyway here is what I have so far: Sid1 Swinsid x 2 Sid2 8580 x 2 Sid3 Swinsid x 2 Sid4 6581 x 2. Unfortunately the Swinsids are not as loud as the real chips but they sound ok. Is it normal that on the 6581 each time you select a different sound that it plays it in very low volume. I cannot hear this on any of the other chips? What should happen if you select L/R or both chips on one sid? I was expecting to only hear the left or the right or both channels but nothing changes, I always hear both channels without any difference. Cheers 60/40
  13. Hi all I figured it out myself after reading the sentence a hundred times. So this one will not be soldered but connected with a removable cable instead. Any particular reason for this? Cheers 60/40
  14. Hi all I am trying to follow this instruction to get a mixed sid setup working. I did everything until the following part. In the instructions it says: - You must install an additional jumper wire between the input of V3 and the main 15V line. J72 pin 1 is an obvious place to connect to V3, and the J25 pin “9V-11V” (possibly unused pad) or pin 1 of V1 (shortest possible jumper) are good places to connect to the 15V line, though you have plenty of choices. I am certainly no expert in soldering but on my pcb there is already a connection between the square pin of V3 and J72 pin 1. Did I make a bad solder connection somewhere or is this normal? Thanks 60/40
  15. Hi dwestbury and listen202 Thanks a million for sharing this! Looks like I can finally finish my build which was stalling so far since I could not figure out how to get Fusion360 to create a proper Toolpath for the Graphics with a cheap 3018 CNC machine. I have only done simple pcb's so far with FlatCAM. I tried to follow your instructions and created a Kicad project. I did not know how to size properly so I went with Listen202's version which seems to be correctly sized. If I measure in Kicad it is (232,41 mm x 163,27 mm). I also had problems with the copper rectangles, as Kicad always complained that they should not overlap, but I hope I got it right. In Kicad itself the Silkscreen vanishes behind the copper, but if I check in GerberView it seems to be correct. If you could take a look at this project and verify that it is really ok that would be marvelous. Cheers 60/40 mb6582.zip
