  1. This unit has sold. Sorry!
  2. I am defiantly interested in selling it. g
  3. Greetings Midi Boxers! I have been member here since 2009. The possibility of building a SEQ is what originally brought me here. I did realize that possibility and have enjoyed using my SEQ4 for many years now. I am retiring this year and I am liquidating my studio so I have a SEQ4 that wish to sell. This SEQ4 was one of the original ones built when the first batch of Heidenreich enclosures were available. It has a custom built power board, Core32 CPU, a Julian front panel, the TK designed back panel, a pair of seppoman's MBHP_ETH PCB and MBHP_SDCARD PCB's, 40x2 Optrex Green on Black high contrast LCD displays and a Quad IIC board. (The IIC board is populated, mounted and connected but I never upgraded the code or config file to activate it as I recall.) I have also mounted some light stalks to make using it in low light situations easier. Two power supplies are provided (One for the SEQ the other for the lights). Pictures can be seen here: http://pushmountain.com/midibox/ Asking $700USD. Includes insured shipping anywhere in the world (I'm in the US). PayPal only. I would really like to sell this to someone in the MidiBox community. Direct questions or comments to: gtxdude at gmail dot com
  4. Mine got to Tennessee today. Many thanks for all of the hard work! It is much appreciated. Gtx
  5. I figured out a way to run my 6582 off of an external 12vdc power supply (2 wire connection). as long as a quality power supply is used, switchers are fine. i used a left over 12v supply from an old (pre lenovo) IBM laptop. The kind with the wall wart in line in the power cord. The audio output of my unit is dead quite with out a hint of switch noise. Your mileage may very, but mine works quite well. Cheers! Gtx
  6. Wow! Great work Hawkeye! Enjoyed that very much. Gtx
  7. I'm connecting an IIC rev2 to a STM32 core running SEQ4. The BLM connection is shown here: http://www.ucapps.de/midibox_blm/blm_connector_mbseq.pdf Where does MI2 and MO2 connect to on the core? I spent some time plumbing the depths of uCApps and the above drawing was as close as I could find. Any help would be much appreciated. Thanks, Gtx
  8. Julian, i find that these parts work fine with the TK back pannel: The power switch: http://www.allelectr...E-SWITCH/1.html The DC power receptacle (2.1 mm): http://www.allelectr...WER-JACK/1.html I used both of these part numbers in my build so i know that they work. This is how i mounted them (look to the right at the top of the perf board): All Electronics is located in Van Nys, CA in the USA. I have bought from them for years; their prices are great and their service is too. However, I find the idea of converting them to round holes opens up a lot of possibilities for alternative parts, and you dont have to fiddle with spacers, drilling holes in the bottom and fabricating a perf board to mount them on. HTH Gtx
  9. got mine today in the USA. Thanks a bunch Freddy!!
  10. I have been hanging out around here for 3 years now. I have built several midibox projects including a MON, Seq3, 2 X Seq4 and I’m working on a MB-6582 right now. Many thanks have gone out to TK for his tireless work on the MidiBox platform and Wilba for his clever UI PCBs and the 6582. All are well deserved. But there is another tireless soul in this community that I would like to publicly thank, and that would be SmashTV. I had completed my 6582 build a week ago and had a problem with the CS. None of the push buttons worked and about half of the rotary encoders were not working. I struggled with if for several days to no avail. Last Tuesday Smash helped me figure this out in a 30 minute chat session. The problem turned out to be an open PCB land on the serial buss between two of the 74165’s. I MIGHT have figured this out sometime during my lifetime. Smash did it in 30 minutes with 4 or 5 questions. A jumper wire soldered between two pads on the main board fixed it. All push buttons and encoders are working now. Smash & Gtx do the “it’s working now dance…†Smash maintains his web site, stocks the parts, makes the kits, ships 3 or 4 times a month (world wide), and always has an ear open on the chat channel to help with those butt kicking problems like mine. Smash, I’m sure that I speak for the entire MidiBox community when I say THANK YOU for all that you do. Your tireless work is much appreciated. We are lucky to have you among us!
  11. 2 X MBSEQv4 2 X MB6582 1 X MBFM I'm located in the USA. Thanks a bunch! GTXdude
  12. Thanks guys. Some great suggestions. That pic of the CS PCB was a great help. I'll let y'all know how it goes. Thanks again, Gtx
  13. Do a search on ebay for "fader knobs". you will get some fine examples of what is for sale. I have done business with this fellow: http://www.ebay.com/itm/MIXER-SLIDER-Fader-Knobs-4mm-Fit-White-X-16-/200825712707?pt=UK_Mixers&hash=item2ec2253043 He shipped quick (he's in the UK) and the knobs were top quality. HTH, Gtx
  14. Greetings. I am asking the collective for help in troubleshooting a problem on my newly constructed MB-6582. None of the push buttons on the CS work. This is what I know: I have been over both boards with a magnifier; no shorts, bridges or rotten solder joints that I can find. All the chips are plugged in with the correct orientation and none are overheating. I am running the MB6582 hex file from this zip: midibox_sid_v2_041.zip After power up the LEDs in the matrix blink in a pattern. Then the display shows the default patch and 10 or so LEDs light in what looks like the default configuration. At this point most of the rotary encoders work but NONE of the push buttons change anything. I have been over the CS PCB with an ohmmeter. None of the switches are shorted closed and measure closed when pushed. None of the steering diodes on the switches are shorted and measure correctly when forward biased. Power rails are the correct voltages and look quite with a scope. The LED test program does not light any of the LEDs. The square wave test program did work. A display plugged into CPUs 1-2-3 shows “Ready.†With out a schematic I am at a loss as how to proceed from here. Can anyone suggest where to look next. I have spent several hours trying to figure this out and I must admit that I am out of altitude, airspeed and ideas. Any help would be much appreciated. Gtx
  15. If anyone has a spare plexiglass window for the MB-6582 i need one. Will be happy to pay you for your trouble and shipping. If you can help me PM or email gtxdude (at) yahoo (dot) com. shipping will be to memphis tennessee, USA (38018). Many thanks! Gtx
  16. Finely got the mini 5x5x5 enclosure built. I'm very pleased with the result. Cheers! Gtx
  17. Hi Juilian, Nice to see you around again. The one that you made for me measures 132.11 mm tall on the exposed (black) surface. if you include the "flutes" on the top and bottom edges that slide into the rails the over all measurement is 135.55 mm, if my old beat-up digital caliper is to be believed. mine fits perfectly. hope that helps... Gtx
  18. Got the metal today for my little hand-held enclosure. Man it looks great! I will most likely have time to assemble it this weekend and I'll update with a few pics when it is done. Carry on, gtxdude
  19. That's the problem with one-off projects like this, the metal is stupid expensive: $130 USD. But if you want something that looks good, you gotta spend the bucks.
  20. Yes, the long piece bends 90 deg at the small tick marks along the bottom edge. this piece wraps around the PCB. The top and bottom (the two smaller pieces) go above and below. The whole thing assembles with some M3 x 35mm cap screws and a few spacers like a sandwich. The side with all of the i/o connectors is left open. Should make a small, smart looking package that will fit in the palm of your hand. Cheers, gtxdude
  21. Here is what I am doing with mine. Just ordered the metal yesterday from FPD. Should have it in 10 to 12 days. I'll post another pic when I have it assembled. Cheers!
  22. Some time ago seppoman ran a sale selling off some extras of these cards left over from a bulk sale long ago. I really need the SD Card reader and the eithernet card would be nice too, but I badly need the SD card reader. Does anyone have a spare of either of these cards laying around that you would be willing to sell? If so, please PM me with details. Payment preferred with paypal, but I can work with you if that won't work. Shipping to the USA. Many thanks in advance.
