  1. I have a number of pre-programmed PIC 18F4685 for sale, already flashed with the latest MIOS. I recently flashed them to help out a fellow MIDIbox community member building an MBSID, but who is not responding to PMs anymore... Shoot me a PM if interested, asking price is 7,50€ (what I payed) per piece plus shipping. I am located in Germany. Regards, ilmenator
  2. For the most part, I've been sourcing my components from either Mouser and or Digikey, but lately I've started placing one-off bulk orders with AliExpress. You can typically find what appear to be great prices on larger quantities of discreet component, but then there's always that large shipping fee (at least to the US) and the significant wait time for deliveries (which typically take 4-12 weeks in my experience). So, I decided to take a look at some of the components I need for a particular BOM and compare the actual costs, side-by-side: In each case, I tried to source the ch
  3. Yo! See picture. Finally decided to part with a way-too-long-ongoing project. A little history about this piece of crap... I started this project many years ago. I was gonna have a SID synthesizer, and I was gonna have the best SID synthesizer. So I bought the sexy junk in the attached picture. Full of energy, I started to put this together. This was finally going to happen. But as it usually works - sometimes life takes some turns here and there that is not exactly planned for. Suddenly, there was kids. Then a larger old house (piece-of-shit) suddenly was mine - or rather the bank's :D heh
  4. Hi, It has been a while - we have moved and i had to do a quick new studio wiring test yesterday night - using some original MB6582 "acid" basslines created by TK.! Many, many thanks for them! :) This was done in only about two hours and is not really a full track (thus the new v4+ was unused). In this video, most sounds are created by DIY devices: * MB6582 for a pair of 8580 SIDs in stereo bassline mode * Mutable Instruments Anushri for the lead * LoopA prototype for simple sequencing * DIY polivoks stereo VCF to filter the drums
  5. Hi, I'm finishing my MB-6582 and can't find where I messed up. Encoders work, LEDs work, buttons work but don't do what they should do. Third bottom button for example makes third horizontal LED line blink, and LED's go on and of everywhere every time I push a button (LCD menu also changes) Encoders work fine. With the matrix test every LED lights up except the Control Env LED. When I push buttons nothing happens en the LCD. No shorts on the U20, 5V on the pins coming from JD5 and 10kOhm to 5V on every pin. I have not used the BC547 transistors and have bridged across.
  6. Hi there folks, New member here, can someone help me find 4 or 8 6582 chips? Thanks in advance.
  7. ALL SOLD. Thanks for the interest everyone! For sale: two complete MB6582 kits. Price is per kit; housing/panels and SID chips sold separately — see below. The only things missing are LCDs, LEDs, power supplies, internal fans, pushbuttons, and half of the encoders -- all easy to obtain. [SOLD] kit available @ $100 [SOLD] housing/panels available @ $40 [SOLD] 8x 6582 available @ $40 ea., (from Wilba w/ capacitors) tested [SOLD] 8x 6581 available @ $30 ea., still testing [SOLD] 3x relabeled (fakes) 6581R4AR, still testing I have been sitting on th
  8. Hey, it has been a while, this song sat on the sequencer for too long and had to be finalized one way or another :). Only using the LoopA (i have to get back to MBSEQ goodness soon :) and six MIDI loops in two scenes, hope you like it :) The next videos uploaded will be build videos for the new SEQv4+ and the LoopA, so you will be spared from new songs from me for a while :) Thanks for watching and listening and enjoy the weekend! Many greets, Peter
  9. Hi, I'm selling two midibox instruments: - sammichFM in acrylic enclosure. Works 100% (knobs, pots, display as it should). The sammich comes with no power plug, just the sammichFM as pictured. asking EUR 230,- - MB6582 fully built in Pactec enclosure, with red display. Includes 6 x 6582 SIDs (NOS ordered back then via Wilba) and 1 x 6581 (ripped from a C64). Here comes the story: It was working 100%. Then I had the MB6582 in storage for about 2 years. If I turn it on now, it will boot up correctly but some of the encoders/buttons will react, some won't. The

    [SOLD] MB6582

    SOLD Hi all. There is MB6582 for sale. Was built in 2014, and then was powered only 10-20 times i think. Too much for me listening SID files and not using all the power of the synth. Back panel is not standard as it was problems to find the power switch and MIDI sockets, so i used mini DIN sockets with Creative Labs adapters from old Audigy 2 ZS Platinum. Also there is no power adapter included, the power can be taken from PC power source or you just can use other 5+12v sources. The synth has internal mini amplifier with small stereo speakers placed at left and right
  12. Hi guys, I've finished building the base of a mb6582 (including display) and so far everything seems to work as it should (Woohoo!). However, after reading Hawkeye's CS tutorial, I've delayed soldering components onto the control surface PCB until the front panel that I've ordered arrives. Until then, I'd like to rig up a minimum CS using a breadboard and switches/encoders for basic parameter changes (menu scrolling, etc). Is this possible, and if so how? Even with TK's instructions I'm not quite sure how to go about it.
  13. As the title says, If anyone has a spare set of front and rear panels they want to sell then I'd be interested in buying them. I'm not too concerned about colour or condition, only that the price including shipping to New Zealand beats what I'd need to pay to fabricate a new set.
  14. No time for anything (sorry, Andy :-)) but the occasional MBSEQ jam ;-) Big thanks to Shuriken for providing the Anushri boards, what a great little synth! Have a relaxed winter season and thanks for watching and listening! Peter

  16. Update: The box is now sold. Hello! I have sold my MB6582 and thus have no use for my 1U rack mounted eight channel PSU/VCF/VCA expansion box. It contains : PSU: 230V input. Powers all Components in the box plus the MB6582 via a cable that fits the MB6582 power input connector. DA-converters: Four nicely soldered AOUT_NG boards control the filters and VCAs. They are controlled from the MB6582 via the expansion port. Analog filters: Four SSM2044 boards fitted with eight SSM2044 chips, relays and styroflex capacitors. Audio is fed into the filters from the MB6582 vi
  17. Wondering if anyone else has had the same issue I am having right now, or if any one knows how to solve this issue? I was playing around with my MB-6582, and of course I have to mess with every option available. I came across the DOR (Disable Oscillator Reset) option and decided to give it a try to see if there was a noticeable difference when switching patches, which I didn't so I turned it back off. I didn't immediately notice any changes or problems. I turned off my synth and when I turned it back on I noticed that I could first off not hear the Mios startup jingle. After that I was not
  18. Hello all, I am building my MB6582 and I would like to use a single regulated 12VDC wall adapter. I already read different posts related to the MB6582 power supply options, but I am still in doubt... Question: can I directly use the 12VDC rail for the SIDs (6582) and a switching regulator to derive the +5V rail? I mean: any problem in terms of noise in referring both the rails to the same GND instead of superimposing the 9V to the 5V one? Thank you! Walter
  19. Hola, it has been a while, but now: Full throttle! Made with a MBSEQ and a MB6582, a few other synths and a gimbal-stabilized-cam DIY hexacopter ;-) Thanks for listening and watching and have a great time! Peter
  20. Hello all, I almost completed my MB6582 and I am stuck at testing the main board. My idea is testing the PICs are running before inserting the precious SIDs. I flashed all 4 chips with "setup_mb6582.hex", but nothing happen on the LCD... I also flashed the 1kHz test FW --> nothing... :no: Supply voltage is OK on all pins and MCLR (pin 1) is high as expected. Cannot see any waveform at the oscillator's pins (10MHz XTAL and 33pF caps are OK). I would say the internal oscillator is not set for external xtal... Anyone got a similar problem starting from blank PICs?
  21. Hi all, I've been lurking around here on the forums for a while now. Some years ago i built my first MBSID v2, completely based on the modular mbhp. The device didn't last very long as i decided to do some modifications and then never finished the work. So poor little sid had to wait for some time, but now i'm back putting the system back together. this time with a mb6582 board. Now, this board is actually finished and tested and looks good and is supposedly working. But there's this one annoying problem i can't get rid of: i can upload to the first core (id 0) and it clones to the
  22. Hello, I am already some time here in this forum but this is my first post and I never thought to sell my equipment.... My family needs space....... Here is the list of my equipment: 2x MB6582 (just the base PCB is soldered, 1 control PCB partly soldered, power supply suitable for 8580 and 6581 SIDs), displays! I made a lot of photos of, so if someone considers to buy just let me know and I will provide pictures! Further I have PAC-TEC desktop housings but no cover plates. € 350,- each SID-chips (some of 8580 (diff releases), 6581´s (maybe six) €
  23. Hola, long time no other music posts here, sorry for spamming the forum, I hope you post some other music soon, before I get banned! ;-) Anyways, had a small live session last night, featuring the fantastic MBSEQ V4 (can´t wait for the mbseqv4 plus model, yeah, more notes per track! :smile:). For me, this workflow is fantastic, impossible to do this in software with any DAW (tried some), so many thanks to TK., who made all of this possible! Also many thanks to J, who constantly provides me with new hardware recommendations, for example the DIY Polivoks filter was his tip - and it
  24. Hola, just in time for the weekend, a new live MBSEQ V4 session and a multicolor vector voyage! :-D http://youtu.be/c1HnoE4Rh5I Hope you enjoy and thanks for watching and listening! Peter
  25. Hi, Distorion festival is coming up in Copenhagen and I just finished my mb6582 a few weeks ago…so I decided to put 22 together. mb6582 is doing the main lead parts. Feel free to take a listen, and thanks from all the help in from the forum :-) https://soundcloud.com/michaelhoby/c64-distortion Cheers
