  1. Hello @Antichambre , des nouvelles de ton projet HAARP ?
  2. midiphy SEQ v4+ , 100% Like new / Assembled with love and great care. Shipping is possible at the buyer's expense (I'm in France but international shipping is possible.) The Sequencer is equipped with custom keys, ordered in groupbuy on the Forum with Bruno and special switch caps. Sold Ready to use with SD Card - 1300€
  3. Thanks for your reply, actually testing the matrix with seq_r (seq_l either) on CC16 (ch1, with the NG loaded) doesnt seems to work, cant figure out if i'm missing something but i will try again this this afternoon. By the way here's another video of the beast booting up, hope it will help find this little problem
  4. Good morning, everyone, I have a little problem with the dot display of my seq v4+, few month ago, after finishing the assembly i had systematicly the first two lines lighting up at the beggining of a sequence, I had thought about the cable but after changing it it persists. As a video is easier to understand: https://www.youtube.com/watch?v=24E-SRoXB30&feature=youtu.be Any idea where this could come from? thanks!
  5. @Antichambre ah joli ! If you plan making more wooden sides you Can count on me buying one. CNC finish seems really excellent !
  6. Thank you latigid on and antichambre , i'm going to work on it :)
  7. @latigid on Hi everybody, I would like to put a simple on/off switch on the beast. Do you have any advice on wich emplacement i can safely cut a trace to do so ? thanks :)
  8. unfortunally the only shop near is a "proxy market" with only beers and chips (not so bad !) , the closest electronic vendor is like 3hours from where i live. Visibly TME seems the solution , shipping is like 8-9euro, i think its the cheapest around so i will stick with them ^^ thanks guys for your fast answers
  9. Hi guys, i have to order back some cable sockets (mouser parts : 89124-0101, 89116-0101, 89110-0101), unfortunally at mouser they are asking something like 20euro of shipping + vat , its more expensive that parts themselves ! so i'm trying to find alternative for shipping to france but i cant find them at the only shop that i know : conrad (shipping is like 6euros with vat). does anybody have alternative sources for these within france and/or with not too expensive shipping ? thanks by advance
  10. Here's the beast! It was my second diy project and after few hours of hard soldering I can finally enjoy this crazy sequencer ! Big up to Hawkeye for his videos, latigid on for support and TK to make us enjoy the midibox seq :) I was largely inspired by Bruno's mods (thanks for Sharing !) . just have to find a solution to correct the light leak between switches (Big problem imho) / wooden cheeks and everything will perfect ^^ PS : what s/n i should label it ?
  11. Hi and thanks for your answer guys, yes i was thinking about the 16X16 (17x17 ?) , the same as here : if there's a new version coming later this year i will wait patiently for some news then :D
  12. Hello, everyone, I'm considering building very soon a BLM and I was wondering if there were still any PCB vendors around ? also how much do you estimate the cost price of a complete BLM unit ? Thanks !
  13. I'm using these mec Switches/caps also, you dont need to modify anything . Simply use standard leds (3.3v) and you're good.
  14. It just misses a huge and ostensible "MIDIbox SEQ v4 +" at the back on the white part to assert the whole ;) Actually i work at a french adhésive Brandt (GT-Stickers) that make premium adhésives, keep me on Touch if you want, we Can Do that on measure :)
  15. everything is running great now, you were right about IC2 cold joint. I just have the matrix that display "mirrored" text can it come from a backward cable or something like that. ? in any case merci beaucoup for your kindness and your advices, i will finally be able to enjoy the midibox seq ! and it wasn't that easy for noob (second diy project) that was not comfortable with English language :) learnt lot of things !
  16. Well, after repairing IC2 pin 16, (i suppose my problem came from pin/pad misalignement) i installed New câbles for each screen and protect the bottom of both oled connectors with adhesive tape, it worked ! With one problem, however, as you will see on the picture. I tested each screen independently / on each port without any change and it appears that the problem probably comes from the core, any idea if it can still be IC2 or some other element? (So close from the end!) Thanks

    Excellent job :)
  18. Just followed every of your recommandations. Checked R33 abcd : 3.2v on all you will find attached also the values that i have on both display ports pins and on the oled itself. after reworking on ic2 a saw a problem with the pin that was in front of C2 (solder did not stick) so in doubt i unsoldered IC2 and the pin was simply missing :/ . Do you think its the origin of oled problems ? also can i bridge directly the pin to C2 or i must bridge from somewhere else ? thanks !
  19. Hi there Everythig is done and before assembling the sequencer, I wanted to test all the functions (always with midibox ng and seq_l/r). R.A.S (good news) except for the screens that don't work. At the second boot I had the right screen (nothing on the left one) which displayed 88888...over its entire surface and at the next boot, nothing, the same for both screens. I test this way (core->JA board->lemec1->lemec2 + both screens) - I checked that J15S is set to 3.3V, -Rework each core weld (in case...) - Checked the voltages, I have the same results as on these images (posted by "SimonSays"): http://midibox.org/forums/uploads/monthly_2019_05/IMG_0137.jpg.7a321f39f767fe44ff31e9f676c01c8a.jpg http://midibox.org/forums/uploads/monthly_2019_05/IMG_0788.jpg.a5e22618fcb98c9437a10976bc2d058c.jpg -tested the lcd command... no idea what to do at this stage;( thanks for any help !
  20. Hi there, not sure on how to proceed but i would like to have a blue /white scheme for the beat led. am i correct if go A->1k res->3 (blue) and B->4.7k res->1,2,3 or i should do fro B : B->4.7k res->1 B->4.7k res->2 B->4.7k res->3 thanks :)
  21. i was finishing all the test then.....I can thank the all mighty god of randomness, i switched one of the lemec board cable with the core one then everything was......working i have pretty luck after unsoldering twice the IC's that i didnt kill anything finally . I was far too confident with my cables, will check them twice for sure now ! i'm out of cable headers but finally the beast should be alive very soon
  22. Double checked but yes, MB_NG is flashed (MIOS detect MIDIbox NG on midi IN/OUT) and i tested both seq_l and seq_r (with seq_r, all ja board leds are lighting up, what the exact diffrences of r & l config files, simply for left/right version ?) . Actually JA Board seems to works perfectly, i have correct feedback within MIOS console (push btns / alp push action / knob) and leds are working correctly when i test buttons. With MEC boards its another story and only knobs turning are sending feeback to MIOS (tested with both seq_l / r).ngc) here the screenshot of what i get in the console. for info between each knob test i'm pushing them (no action triggered in console as you can see), same for mec switches and the matrix on CC16 (chn 1), not working . No succes with "set dout" function either unfortunally (dunno if its possible to test ic with a multimeter ?). So for you , only IC2/3 (on both MEC boards) need to be changed or its better to replace all IC's ? for now its only my second diy project (first one was a xoxbox few years ago), i didnt had ocassion to stock spare parts but for sure i'm going to order enough "in case of" :) Thanks
  23. Okay, so I just checked the cables: no problem, obviously. I also unsoldered / soldered back ic2 and ic3 together without success. The problem is 100% identical on both lemec pcb. Under MIOS, when I turn the knobs, I have a correct return of the values from both boards with the debug mode enabled, but no action is triggered when I press one of the buttons (alp push or lemec switches). Out of curiosity, I tested the pcb lemec (the smallest) by completely removing IC3 and the problem is the same, maybe that can confirm that IC3 is dead ? In your opinion, does this mean that certainty both IC3s are dead (because of the inversion?) and does the problem with the matrix also correspond to these ICs? I am waiting for your answer and I will order some spare parts. Have a good day and thanks :)
  24. These are the same ICs, I unsoldered them with hot air and soldered them back with iron (my paste is poping !). I'll apply your advices in the evening and I'll give you a feedback:) With Mios I have a normal feedback by turning all the knobs but nothing from pushing them, same with mec switches on both pcb.
  25. Thanks for your fast answer latigid :) , yes it's the core I was talking about but you have the eye and after welding in the right direction ic2 and ic4 (on both pcb) everything was working and I was finally able to do the test. In this case, the encoders work perfectly but their push action doesn't work, its the same for the mec switches and the matrix (i was on the correct cc/channel). Do you have any idea what I need to check ? pretty hard to debug when you are a noob i admit. thanks by advance
