Thx, flyweight :-) I think i just rotated the polarity protection notch of the socket, that was soldered on the backside by 180° and built a standard cable* - but I am not sure, it has been a while :-) Note, that the pinout of the serial connection is also quite symmetric, that's maybe why it worked. I remember to have thought about the step for a few minutes back then, and was convinced, it was fine :-) The LED #31 should be rotated, it is possible, that it lights up, when it is not rotated, but it will likely mess up the LED matrix and compromise other LEDs... EDIT: * or built the cable with one plug 180° rotated Have a great time! Many greets, Peter

Thanks, man! We are currently proceeding only slowly, as all hell broke loose this year :-). But - the hardware will be completed (additional displays on the way) and there will be new synth targets, just need more time :-) Many greets, Peter

Great session! :smile:

Thanks, guys! :clover: (Phatline: regarding multi cam recording controlled by your pc - i have no clue! Also, I don't have webcams, as the computer is always off, when sitting at the synths... So I just grab any cam available (GoPro, ...) set them up and start them... and then use a visual cue to sync them - e.g. clap the hands, or push the seq play button - this allows to overlay the video tracks in any video cutting tool like premiere, etc, but you are right, it is quite some work to cut everything afterwards...) Many greets, Peter

That was proper oldschool, man :D Keep it up!

Great session length! I always mess up after around 3 or 4 minutes or so, need to learn how to chill :-) The SEQ V4 is awesome for this kind of stuff, keep it up!

Fast stuff! Loving the distorted drums! :-)

Hola, Finally, glad to see more action in this subsection of the forum, please keep them MIDIbox tracks/sessions posted, they are all inspirational, especially seeing different SEQ workflows in action! I think, i am the only one working primarily in the track mute screen, right? ;-) Many thanks to TK. for this great hardware sequencer and jojjelito for the name suggestion for this track :-) Have a great time! Peter

Thanks man, that sounds A+, me was already worried :-) No progress without hardware deliveries ;-) :hyper:

Thanks, man! :-) We are currently in the process of finishing our first units (still need to install a few more OLEDs) - and then another synth should be adressed as the next Programma target. There are also nifty features like an external joystick (for vector mixing patches) and a few faders for easy envelopes (in an external box) in the making. Many thanks for your suggestion! Easy synth switching is also on the list! :-) Unfortunately, work hit us really bad this year, so it will be a long ongoing project, but that is part of the fun! :-) Many greets! Peter

Woah, really hard to resist (but the gurl would notice "another piece of hardware" and i would feel the Nudelholz, again ;-)). Awesome job with the routing, respect!!! Many greets, Peter

Thx, man! :-)

It looks awesome! Congrats! Loving the smoked acrylics on the TPD! :-) Many greets, Peter

Hola, it has been some time, springtime lazyness hit bad and all, but finally... :-) This track is more of a video collage of good memories of the past few years, hope you enjoy! Made with a MB6582 and an Alesis Andromeda, all sequenced by the great MBSEQ V4! Thanks for watching and listening and have a great springtime! (The plants in the pictures are agaves, of course! ;-)) Many greets, Peter

Thanks a lot, J - maybe you should get one, before legislation steps in and allows only paperplanes to be launched by mere humans ;-)

Hi Vito, as far as i recall Thorstens arguments, the last time he was asked, he said, that there is no real benefit in moving up to a more modern core, as the SIDs can only accept a moderate register update speed - so basically, all the bases are covered with the PICs... development would be a major effort and there may be other low-hanging-fruit goals (aka other projects) in the limited devtime available... but this is all hearsay :-). The great thing about MIDIbox is, that everybody can step in and develop to his/her hearts desire, it is all documented, you could give it a try! Many greets, Peter

Thanks, TK.! Enjoy the Canaries! :D

Thanks, guys - Corralejo it is! :-) Shuriken: you should buy one! :-) Many greets, Peter

Hey, here is another MBSEQ V4 based live track :-) Alesis Andromeda vs Waldorf Micro Q vs Elektron Machinedrum Video filmed with an X8 Octoquad in Fuerteventura :-) Thanks for watching and listening :-) Many greets, Peter

Yes, I think, the morph function will be great! When MBNG supports it (it is still on the wishlist, i think), the Programma, which is nothing but a MBNG, will do it, too! :-) Many greets, Peter

Attaching a few more photos, while we wait for the boat from china to bring more displays :smile: The display cabling is a bit of spaghetti, but well doable with enamelled copper wire. The displays will happily "stick" between the LEDs, they are exactly the right size. Of course, maybe in the future, somebody designs PCBs that allow for easier mounting without those wires! The encoders currently use a single switch line, that is shared with the "SHIFT" menu button. This could be changed, but then we wanted to save on DIN ports, as the idea was to attach as many LRE boards as possible :). Parameter input accelleration (when pushing the respective encoder) works fine and is really intuitive. Many greets, Peter

Yes, it is a nice LM2596-based 5V-5A switcher, that i use with confidence in flying projects as well: http://rctimer.com/product-160.html it is cheap and also already comes with a connector, that fits perfectly on the STM32F4 core board - just pull the "USB Power" jumper, add this thing, and you are out of power-worries :smile: You can use an old notebook PSU from ebay (1€) to power it - these often deliver 15V to 19V and are perfect for this job... it can also easily handle the additional load of the linear ldo regulator for the displays... But, I really like J's more professional solution of an integrated switching "full" psu - this avoids external cable/psu mess - but of course you must take care to not get electrocuted :-) Many greets, Peter

Regarding the current draw of the LRE-boards - i didn't measure yet, but - we are talking about 32 shift registers, quite some ULN darlington transistor arrays and 4 x 16 LEDs that are lit at once (multiplexed). So for the LEDs alone, that could be 64x ~10mA of consumption -> the LEDs alone are far above USB power specs. That causes the 5V rail to drop, and then weird things can happen. -> J's advice of using an integrated switcher is a good one. I went for the cheapo wallwart + LM2596 method, cause both were floating around anyways :smile: Many greets, Peter

Thanks! Regarding TK.'s wish for more buttons on the control surface... How about using the menu button to enter a "fullscreen labelled menu" mode? After pushing it, a new page is loaded, that offers up to 64 slots for * unique actions to be fired (e.g. .ngr scripts) * configuration settings to be modified * synth patches to be loaded from sdcard and dumped to the synth * synth patches to be stored on sdcard * programma configurations (aka which synth is controlled) to be loaded via a single tick/turn of the respective encoder. The OLED labels would show which action is mapped to which encoder. The encoder LEDs can be used as function status LEDs, when necessary. Also, on this screen, certain settings could be adjusted, like the MIDI output channel for the synth and so on. Would that work for you? It would be like a giant flat menu system available (without hierarchy/scrolling) after a single button push, with many free slots for user actions (e.g. ngr script launch). Many greets, Peter

... looks good! I dunno how much current your other elements draw, but for the Programma, adding the 7th display gave some strange problems that could only be solved by *both* adding a 3V3 vreg and obtaining the 5V not via USB. That was probably caused by overload by the many LEDs, drawing quite some current and the STM32F4 regulator, that seems to be a 3V0 (?!) regulator - i measured 2.9V input voltage to the displays, which is already a bit low for the internal charge pumps. As you probably don't have soo many LEDs, it could just work fine. But as you probably need power for the motorfaders anyways, adding a LM2596 (or similar) to obtain 5V seems recommendable. Many greets, Peter
