  1. Hah I was talking about this yesterday oddly enough (with MBCV to use as an external filter).
  2. Zero Circuit

    This is fantastic Hawkeye! Your music never disappoints! It brought me back to these forums (been a while since I've been here!)
  3. New Ploytec USB3.0 16x16 MIDI Interface

    Ah man so close, but I still want a Rackmount solution fairly badly. My GM5 is sitting on a rack shelf in the back with some nylon screws and standoffs. It works fine but makes things awkward and a bit vulnerable (it's not in an enclosure). But otherwise that's an impressive option if it lives up to the hype (and if it's using the new Ploytech chips I'm guessing it is).
  4. New Ploytec USB3.0 16x16 MIDI Interface

    Ah that's true, could be. I'll have to see what's triggering that (I'd imagine it'd have to be a VST ro something), although I thought I worked around that recently by switching drivers or doing some sort of voodoo (I moved from OS X back to Winders recently).
  5. New Ploytec USB3.0 16x16 MIDI Interface

    geez, latencies are already pretty damn good on the GM5 relative to many other interfaces. That's also good to hear! I'm at the point where, build or buy, I need a MIDI interface that has multiple ports, handles sync well, is low latency, and reliable. GM5 almost gets me there but sometimes it just likes to completely junk out while I'm in Ableton Live (it's entirely possible it's something I'm doing since I'm the one that populated the board :P). Rackmount would be a nice plus.

    whoo!!! Looking forward to this! My GM5x5x5 is a bit quirky these days.
  7. Mmmk so first, this is absolutely gorgeous! Second, can I ask where you get your boards fabbed and how much?
  8. Oh wow that sounds pretty awesome! I hope you keep us updated! I haven't touched FPGAs since college so don't have much to share other than my enthusiasm. But with the SID supply drying up, it's nice to see more FPGA solutions come about. Ones that can work with MidiBox, in my opinion, are all the better!
  9. MB-6582 in Ponoko case

    Yep, SMD was basically required because some of the modules just didn't have enough room without without having to use another board somewhere. I had to do that for the LED Matrix. The top layer plugged into a button board not unlike how the sammichSID works. I lost the latest design I made of it, but have older versions still around. Doing a full CS as one large board might avoid having to use SMD components, not sure. I might look at kicad again to see if I can make that happen. Wiring it all up wasn't too terribly difficult. The fear of having to make an expensive CS board, and front panel, and have them not fit was a very real fear though :) I like the rackmount idea though because there's so much room for activities! Such as a passive mixer, balanced outputs, cooling, maybe some SSM boards (although for that I think MBCV is probably the better route to go, something I'd like to try at some point as well).
  10. MB-6582 in Ponoko case

    I tried it not too long ago. The problem was the it was fairly spare on the component libraries, but otherwise I liked it well enough (and it ran in Linux is I'm not mistaken which is not my main desktop when not actively making music anyway). That may have changed by now, though. The CS isn't using anything special part-wise. For the modular versions, I mounted the 165 and 595 SMDs directly to the CS and each module had basically and in and out to chain them together (not unlike how DIN/DOUTs work). For a single board, I'd likely do something similar but could also adopt the button matrix that the MB6582 used, though I liked having fewer cables involved (unsurprisingly since cabling has been my downfall for the MB6582).It'd be nice if I could use through hole as well just in case a chip fails (I think I have a failing shift register on my Virus Classic for instance, and I still find socketed chips are much easier to work with than SMDs..)
  11. MB-6582 in Ponoko case

    My MB6582 has been sitting in a box for years now :/ I tried to fix it, again, in 2015 I think, but the baseboard to CS cabling connections just have never worked for me. I still want to make a custom control surface and just rackmount the thing. But yeah I'd love to see your design ilmenator! That'd get me something that may actually work for me at least ;) Alas, I had all my rackmount control boards done but somehow lost them in the ether :/ Honestly for how much the individual boards cost, if I could somehow swing making a large board I would (but EagleCAD is $$$ for boards of that size).
  12. MB-6582 diy PSU question

    If you are running 8 SIDs, .5A might not be enough, but I can't remember what the current draw was. My MB6582 power supply draw was under 1A on both as I recall (I used 78xx linear regulators, which are typically only rated at 1A). I think the first PSU would be safer as far as headroom. That said, I couldn't find the switching frequency and that's arguably the most important statistic. Question is, do you want to trust a PSU to your irreplaceable SIDs? If you've come this far, I wouldn't skimp on the PSU (if it were me) if you are going to go with a nice switchmode. I'd suggest seeing if Meal-Well has a PSU that suits your needs (again, pretty sure there were some suitable models mentioned here on the forums or on the wiki) since they public their switching frequency and all well regarded. In a pinch, you could run multiple wall-wart PSUs (a 5V and a 9V) if you can get nice linear regulated ones (switchmode wall-warts will likely be very noisy for audio). Jameco has some, for instance. That could get you buy while you find a better long term solution.
  13. MB-6582 diy PSU question

    There are posts here about using switch-mode supplies for various MidiBox projects since you would want 5DC and 9 or 12DC ideally. I believe you can find switchmode PSUs that offer both 5VDC and 9VDC, but if you can't, you can use a regulator to bring it down to 5VDC. Thing to be careful about here is you need one that has a high switching frequency and good filtering since you are using it for audio applications. The forum has plenty of discussion around this though. A C64 power supply offers +5DC and 9VAC (hence the transformer mentioned up above), which is options A or B for the MB6582. Might be ok if you want to use it for a C64 when you're not using it for your MB6582, but this design dumps more heat into the 6582. And if you were going to build a C64 compatible PSU, I would recommend just buying a new C64 PSU off eBay. They at least use more modern components, are cheaper, and would get the job done without you having to work with mains AC voltage.
  14. I know there have been quite a few designs of a GM5x5x5 enclosure here and was curious if anyone might be able to share their designs? Rackmount would be ideal but I've seen a few laser cut acrylic designs for say Ponoko that looked pretty cool. I've had the thing stuck in a Lego enclosure and then had the thing mounted on my wall using push-pins :P Both methods aren't particularly good.
  15. midibox SID rack 1U project [completed]

    That looks lovely! I was trying to combine a sammichSID and FM into a 1U a while back. Never did get around to it :/ Can I ask where you purchased the 1U rackmount enclosure? That has always been the big headache for me with rackmount-anything.
