  1. I read a lot of guides. Successfully compiled ASM code. The OLED display works well with an 8bit driver. If anyone needs the firmware, here is: setup_sammich_sid_8bit.hex

  2. Hi ssp, I don't remember if labels can be called from a map, but i don't think so. However, i think it is possible to change the display using a .ngr script. Bests Thomas

  3. Hey man. It's actually an FR4-Standard PCB. Non aluminium. But seems pretty robust anyway.

  5. maybe its the Ripple off the PSU about your PSU - reichelt specs is saying : "Ondulation résiduelle : 80 mVcàc" i guess this is not a 50Hz ripple but HF ripple... --- i guess some small cap (100nf, 10pF) and a big Cap (depends on the load, use for example a 100uF and a 2200uF) on the output off the PSU would reduce that "ripple"... * maybe that caps are not enough and you need some more filtering (coil, resistor, lpf...) but i would start with some caps... the connections in your 2nd picture are not necessery - i guess (dont seeing the whole picture, but i think so...) --- so picture 1 is correct. by the way - its only the last LED that flickers? maybe you have to terminate the DO line on the very last LED off the Chain with a 10K resistor to 5V or Ground. else it could be a software problem, when the software loops thru the LEDs, and when it comes to the last one it jumps to the beginning off the chain... try to programm in the ng code one more LED (which in reality not exists) - so you can be sure that this is not a software bug... - but dont ask me about ng-programming --- no glue about that. - mike.

  6. Hello, first of all thank you for your previous answers. I haven't fixed the problem with the pads yet. I'm focusing on another problem for now: with the LED rings. with 16 led ring of 16 led no problem. when I add more, the LEDs flicker. https://youtu.be/HyLkVeFtALw?si=gT09lbCxEwLRmHt8 I read here: http://midibox.org/forums/topic/21095-lre-4x1-breakable-rgb-led-ringrotary-encoder-pcb-bulk-order/?do=findComment&comment=184155 FantomXR had flickering problems, solved with a 10uf capacitor. Should I add a 10uf capacitor at the input of my LED ring cards? (as in the image below) (C129) To understand my configuration see the pdfs: LEDRING: https://drive.google.com/file/d/1XpDQBUE42IqXpXicO--B2gfIoNQDh5ga/view?usp=drive_link “power card”: https://drive.google.com/file/d/1NJ-H-QXD-tl9rU6nbYdEh2Q4jFqjWt6b/view?usp=drive_link I made a PCB that I call a “power card” that I supply with 5v 10 amps. The J2 connector of the "power card" is connected to J4b of core 32. Connector J44 of the first OLED card is connected to J3 of the “power card” Connector J45 of the first OLED card is connected to J4 of the “power card” Connector J44 of the second OLED card is connected to J5 of the “power card” Connector J45 of the second OLED card is connected to J6 of the “power card” etc.. Thank you

  7. Hi all , Was wondering about opening a KiCAD Section in the wiki? For tutorials , midibox libs etc... where should i put it? regards, JK Edit : A Frontpanel designer section could be useful too ?That's a soft that i think most of us use? Maybe create a "Softwares" Section?

  8. the next generation off Triggermatrix, with insights to shematic, the board-files i will not set free... the Pictures from the Boards are for debugging reasons only. where possible, i made pick and place ready boards - to reduce soldering time... at this point the big BLM16x16 board is not pick and place ready.

  9. i made a passive design, since the fan which came from mouser, was dead from the beginning... since it is a 6582, it was not going very hot anyway... but i drilled Holes into the pcb under the SID-Sockets, and cut aways some plastic from the socket too. i too drilled some holes in the plastic body under the Main-PCB too, the backside off the SID should be enough to get rid off the hot air...

  11. Hi Long time I don't play with NG config, but It should be possible with enc_mode=Inc41_Dec3F , combined with fwd to 2 sender and conditional filtering, something like if_equal=0x41 send note A, and if_equal=0x3F send note B ?

  12. @ Faderboard 1 & 2 Mounting holes labeling not necessery again. rest is ok. you may could label + and - beside the 2x5 shroudet Pinheaders, so there is no chance someone reverse it in a way... in generell... normally the Nose- says all, but someone could crimp the cable incorrect... so if he controll measure, this is a good hint then for him.

  13. @ pusbutton: the LEDs in the shematic are REVERSED for example look into: http://ucapps.de/mbhp/mbhp_doutx4_32leds.pdf but in the board itself the Silkscreen for the Diode is painted correct - so if somebody just solder the PCB without looking into the Shematic - all is good, when someone look into the shematic he may be confused a bit. what type off Switch are using here > type it on the silkscreen - like you did on the Potentiometerboard. because: i see in the footprint its a le mec > then there are different types, with different Switch contacts - like you see here: 5GTH9 + 5ETH9 will work, while 5GTH9 with inbuilt LED will not work off course... i for me find the correct switch matching to your PCBs Footprint-Pinout - a bit hard... so label the type.... the rest off the PCB looks ok.

  22. could be... you can try to filter out some psu-spikes by soldering a 100nf (maybe add also a 1uF or higher for too more stabilize the psu as addition) cap between + and - on the potis legs (most off the time these are the outer 2 legs off the trio)

  23. look into ng documentation if there can be set a offset for the middle position so it stays on a position... because pots directly to the core is always a bit random... better use for example: http://www.ucapps.de/mbhp_ainser8.html then you have less random values also check the quality off PSU...off course a faulty pot can be the reason too

  24. @ cherry: the switch itself you can get already from eg https://www.reichelt.de/tastaturzubehoer-c8099.html?ACTION=2&GROUPID=8099&SEARCH=*&START=16&OFFSET=16&CCOUNTRY=445&LANGUAGE=de&r=1&SID=967792150a00d890464504461a66ae529d97182e528c945af4544 caps: amazon, alibaba,.maybe.some thing like that: https://www.amazon.com/dp/B00FYO8EDC/ref=mp_s_a_1_5?keywords=flat%2Bkeycaps&qid=1675511770&sr=8-5&th=1&psc=1 https://www.cherrymx.de/en/dev.html the low profile is maybe interesting....

  25. @poti; if the shaft's center is in the end on the same position - so same frontpanel holes can be used.... and: when soldering the thing: first mount the pcbs with loose potis on the frontpanel then solder it (and document this in the "how too build"... @ - : use thermal destress traces (cant remember the kicad word) when using groundplanes, so you can desolder the the poti much easier.

  26. this will take a while - look into the forum in 5 weeks or so. i need the PCB to make a new version off Triggermatrix (http://wiki.midibox.org/doku.php?id=triggermatrix4) the Frontpanel is not a generic MatrixController thing - it has 17 Displays, 8 Faders, some rotarys and buttons, the Software for this is not a normal Midicontroller-code (aka Midibox NG) - its my own creation a sequencer based on MIOS. - but if i not make a shematic mistake, the pcb should be usable like the orginal BLM16*16+X in other Midibox Projects.

  28. Oh, wow, I totally missed that! Thank you!!! I wasted an entire day rummaging around and didn't manage to see that :) Just in case others run across this: You want 4SPI configuration, not IIC like I have in the pic. The number of screens you have must match the configuration you set in the bootloader, otherwise you get noise, and won't be able to write to all the lines/columns Also easy to miss, but for the 1306 RES connection, you need to wire it up like this (again, connections on your 1306 PCB): GND -> 10uf cap -> 1k resistor -> VCC. Once done, RES will be tied to where the cap and resistor meet (like this) It wasn't clear to me how to actually use the bootloader for the STMF4 board, but it's essentially: Plugin your board as you normally do Open MIOS Studio Click Browse and choose the mios32_bootloader app (download here) Click Start. If it won't complete, try unpluging/pluging the board and trying again Unplug/plugin the board In the MIDI IN and MIDI OUT sections whatever app you had prior to all of this might be listed, but it doesn't actually exist (and it shouldn't). That's why you now see the error "No response...". The new app, MIOS32, took its place and you need to refresh to see it. Click Application -> Rescan MIDI Devices Click Understood in the pop-up (this will make your old app disappear, and the MIOS32 app show up) Change MIDI IN and MIDI OUT to MIOS32 Enter these one by one into the input box: (send a command to MIOS32 application). Keep in mind lcd_num_x must match the number you have chained: set lcd_type GLCD_SSD1306 set lcd_num_x 1 set lcd_num_y 1 set lcd_width 128 set lcd_height 64 store Yah. Bootloader is done. Time to restore your app in MIOS Studio: Click Browse and choose whatever app you want, like midibox_ng Click Start. Like the bootloader, if it won't complete, try unpluging/pluging the board and trying again Unplug/plugin the board Now for some test display data. Lets set some values for your SSD1306 OLED's in MIOS Studio: Click on Tools -> MIOS32 File Browser Click Create File Create some name like LCD.NGC Click Update Click on the file you just created Click Edit Text and add the following test example: RESET_HW LCD "%C" LCD "@(1:1:1)A23456789012345678901234567890" LCD "@(1:1:2)B23456789012345678901234567890" LCD "@(1:1:3)C23456789012345678901234567890" LCD "@(1:1:4)D23456789012345678901234567890" LCD "@(1:1:5)E23456789012345678901234567890" LCD "@(1:1:6)F23456789012345678901234567890" LCD "@(1:1:7)G23456789012345678901234567890" LCD "@(1:1:8)H23456789012345678901234567890" Click Save You should now have 8 rows and 21 columns of text. If you need to flip it 180 degrees, you can redo the steps above and add set lcd_type GLCD_SSD1306_ROTATED before you store.

  31. pcb arrive, soldered 4 off them (12 channels) - the 4 others i make a nother time. (24ch in total) the display drivers from Andy work great again! the midibox code is working, the max for live patches too. (at least for this state i am happy to get automaticly the Channels names, and the Macronames!!! hell yeah!)

  33. Notwithstanding a possible bridge day, last Friday of the month (27.05.22 / 7:30pm), online: We organize our regular Open Hardware Happy Hour (O3H) again! This month’s topic is Open Music, since Open Hardware is of course also a topic in the field of electronic music devices (and more and more on the rise). Among other things, we will present the sample sequencer by SucoFunk, The beatmakers’s sketchbook, an Open Hardware device that was also featured at this year’s Superbooth. We have asked for other speakers, so be prepared to be surprised, and bring your own (music) projects! Presenters will include Marc Berendes, Berlin-based Open Hardware developer at SucoFunk. Marc Berendes: The beatmakers’s sketchbook – An open sample sequencer for beats on-the-go (https://sucofunk.com/) (tba) Language of the presentations will probably be German this time.

  36. Hi everyone! Quick update here. I finally finished my controller and installed it in my small control-room. Here it is. I really like the way it turned out, i'm working with it since 2 weeks now, and it's a real bonus to the ergonomics. It still have room for improvements but that was expected and i will continue to work on it in the next future. I'd like to thank everyone on this forum who helped me build this and a BIG thanks to TK and all the midibox team. Without this place I would have never been able to even start this project. Cheers, Thomas

  37. It's not quite clear to me what you want to do? You want to have one J89 SRIO chain and switch between several Cores? If that's right, it is trivial to make a Johnson counter/decade counter out of a 4017 chip. You could think to use the output enable pin(s) of the buffer (541 or 125) that is used to interface the buss to the core. Each Core gets one buffer with the datalines connected to the inputs (+DIN to an output), the outputs are common to the J89 chain (+ the serial in). Advance the counter to "turn on" one chip.

  38. @Hawkeye Thank you for the thoughtful replies. It is easy to think of future wishes and add ons but at the same time forget about how it would effect everything else. I love the Seq4+, very little I would change! And the fact that I can get into the code and try things myself is pretty amazing. That alone is a "feature" that very few seq's can boast. @flyweightIf I was looking for more humanized recordings I'd use the longer tracks with higher divisions OR the humanizer feature! Also, you can specify your own shuffle parameters, you may find something that gives you YOUR feel.. if you could analyze how your beats groove, you may just be able to create that groove as a template and there ya go. May be worth digging into. At the same time, your experience and learning from building the Seq is not lost if you sell it. You lost time, yes. I'm sure if you put it on the market it will sell pretty quickly. ~Steve

  39. Quick heads up on this for anyone that might wanna do this. I had some trouble compiling the above version for Linux Mint 19.3. Couple things you might need to do: ./configure --without-residfp This was giving me a weird "you need to be on a 32-bit platform at least" error (I'm on 64-bit, Ryzen) but we don't need this for outputting to an MBSID anyway The makefiles do not add -pthread. There's probably a more elegant way to fix this, but I just edited src/Makefile and added `-pthread` to the end of CFLAGS, CXXFLAGS and that seemed to avoid the errors You may need to symlink /usr/local/lib64/vice to /usr/local/lib if installing system wide (otherwise stuff like keyboard input doesn't work) You need the ROMs of course! Doing all this allowed me to bust out the HVSC intros included in the collection. Seems to work like a champ!

  40. Hey people, thanks to @TK.! It's working great. Anyway I had still some flickering on the LEDs. As I stated above I left away the caps ... and this was the reason. I know have added a 10uF on the input and on the output-connector of the LED-rings and the flickering is completely eliminated! Great!! So, one core can handle a total of 10 LED (10*36=360) rings....
