Keine Panik, der Link zeigt vermutlich seit dem Servertausch ins Leere, aber die Seite ist ja noch da (siehe oben). Vermutlich fehlt einfach eine Webserver-Einstellung, die www.midibox.org/dokuwiki/NAME auf wiki.midibox.org/dokuwiki/doku.php?id=NAME weiterleitet. Ciao und viele Grüße, Peter

Stuck at Rebooting MIOS after midibox_sid_v2_044 upload
Hawkeye replied to mrzottel's topic in MIDIbox SID
Hola, Maybe not very helpful, but I have an old Core8 lying around here, with a running version of MBSID. There is only a display attached, no other modules. Just to confirm, that you don't need DIN/DOUT modules and also the SID module needs not to be attached - the application will start up fine and should show the MBSID start screen (an empty patch). It is also not necessary to modify any CAN bus/display lines for this test. You could just leave D0-D3 unconnected, the display should be initialized in 4-bit mode by MBSID (only using the upper 4 data lines). Can you disconnect the MBSID module and see what happens? Maybe there is a connection/power problem there, just try to run only the core and the display for now. Which display do you have? Is it 100% HD44780 compatible? If not, this might be a problem (maybe the other apps used 8bit mode for the display, which worked fine). So, here are some ideas: * disconnect the MBSID module, check for success * make sure, the display does work in 4bit mode * in MIOS studio, after the MBSID app should have started, you can send some notes via the virtual keyboard (make sure, the PC MIDI out is connected to PIC MIDI in). If the SID module works, but the display does not work, you should hear some basic SID sounds :). * measure voltages, the PIC should have at least around 4.75-4.8V, otherwise it might be unstable or the app could reboot/never start.

BLM 16x16+X PCB and case order [CLOSED/waitlist]
Hawkeye replied to latigid on's topic in Bulk Orders
Ok, you've always had me convinced, also in for pcb+case, if you do another run, thx for all the work! :) Many greets, Peter -
Ok, this is really strange, am nearly out of ideas, sorry :-/ * Can you measure voltages across the 74595s? Again, lower left to upper right corner? * If you have access to a scope, can you attach its gnd probe to gnd and the tip to the 74595 pins 11 and 14? On both ICs, 11 should give a nice continous serial clock output, 14 some individual pulses for controlling the respective sid inputs... * Last idea: if you unplugged/replugged a lot of 1/4 inch audio cables in the last 6 years, check the audio output plug - i've seen broken ones, that distort the output signal in a way like the one you've described... but this is super unlikely... signing off and best of luck! :-) Peter

Sorry, that the recommendation did not help! :-/ Can you measure the voltages arriving at the problematic SID? Between pins 14 (lower left corner) and 25 (above mid right) should read about 5V... Between pins 14 (lower left corner) and 28 (upper right corner) should read about 9V... Many greets! Peter

Which encoders should I buy for SEQ V4 build?
Hawkeye replied to fundamental's topic in Parts Questions
Thanks for the feedback :) Note, that the Alps STEC encoders need "DETENTED1" mode in the MBSEQ_HW.V4 config file, as they have a different pinout, but somehow work fine using that decoding mode. Other than that, mine still work flawlessly after about 5 years of heavy use, not a single one has failed, or feels wobbly, you still feel the steps, so they are still highly recommended. :) Many greets, Peter -
Cheers, if you don't mind replacing the transistor, do it as a test, in only costs a few cents :-). If it is damaged it might compromise the sound, even when you "listen in" directly at the SID output pin. But as a warning: it is not super likely, that this is the problem, these things usually last for a while... But on the other hand, if you look at the schem here: http://ucapps.de/mbhp/mbhp_sid_v3.pdf there are not soo many other components after the output side. It might also be one of the caps dragging the sid output down to ground, but this is even more unlikely... start with the transistor and if it does not work, we need to ask someone else :) Many greets, Peter

Hola, recommendation: quickly resolder all solder points on the lower pcb, add a little bit of solder to each point after reheating. It might be a gone-bad solder connection, even if it looks good - i once had one on a core32 board - absolutely invisible, resoldering helped :). The process should not take more than 30 minutes, if it does not work, report back ;-). (it might be a problem in the output section of the right sid. see the mbsidv3 plattform schems on ucapps.de - it is the area around the bc547 transistor - unlikely to fail but it might be that one, too). Many greets, Peter

Falls das nicht klappt, hier ist noch ein hilfreiches Tool, was SD-Karten einmal komplett überschreibt - ist manchmal hilfreich, wenn die SD-Karte in einem undefinierten Zustand ist und nicht mehr richtig erkannt wird, z.B. nach einem Power-Off während eines Schreibvorganges: http://www.heise.de/download/sd-formatter.html Ciao und viele Grüße, Peter

Andy, that was an obvious hint, just send TK. a machinedrum and you'll get your code! ;-) Hehehe! Just joking! :-) Would it be an option to transfer the drum patterns from the BLM/SEQ to the MD in machinedrum live record mode? Many greets, Peter
-
Loving the machinedrum a lot here, too! :) Currently, for me, using the machinedrum sequencer as a slave to the mbseq is already very nice and offers more possibilities than the seq as a drumsequencer alone. For example, the MD has those parameter locks, the 16 crazy LFOs, the ram/sampler machines... but i know you probably want to control the MD pattern contents via BLM, which makes sense! :-) If you are "just" aiming for simple whole-track mute/unmutes (like ableton clips), some time ago, I had the idea of writing a small external "mute/unmute" arranger/controller box, that can handle muting/unmuting of tracks on the mbseq (and should be able to handle that on the md, too). I know, that there is song mode for that on the seq, but i was thinking of a retro inspired tracker-style mute/unmute interface for up to 16 seq tracks and 16 md tracks. Unfortunately, there is currently not much time available here, and also that idea differs quite a bit from your usecase - I guess you'd wish to "step-program" the MD externally, to which I unfortunately also have no solution, because you'd really want those additional track-features the MD has to offer... if you don't want them, you could use a simple 60€ sampler like an E-MU ESI instead with the same results and easier MIDI control... Many greets! Peter

For the non-filter parts, just about anything recently modern should do fine, they won't change the audio quality and even a high tolerance would be no problem... For some areas (power section) you will need electrolytics caps, as they are the only affordable ones with a high capacitance. Then you will need a lot of 100nF ceramics, these are small power filters in front of most ICs.... Many greets, Peter

Maybe this old thread helps! :) Many greets, Peter

Keine Panik! :-) die Alps 12mm Encoder gehen trotz anderem Pinout mit dieser Einstellung in MBSEQ_HW.V4 (siehe Phototutorial): Hab das gerade auch nochmal getestet, mit Alps Stec12E08 mit Pushbutton - kein Problem! :) Ciao und viele Grüße, Peter --------> For the Alps 12mm encoders, please also change the encoder type to DETENTED1 throughout the file: ENC_DATAWHEEL 6 2 DETENTED1 ENC_GP1 1 6 DETENTED1 ...

Sounds good! Thanks for sharing your research data regarding power consumption of the SEQ and especially the minimum current requirements for one of those meanwell switching PSUs! Have a great weekend! Peter

So, MBSEQ supports 64 DOUT + 8 AOUT, while the linked device supports 16 DOUT + 16 AOUT, where is the problem? :-) Not intended as a critical posting, just trying to understand, what the goal is? You can always chain up a few MIDIboxes (not necessarily all of them running MBSEQ) specialized/adapted for your needs, it just needs a bit of programming, but everything is really well documented and easy to do. Many greets! Peter

Also, some feedback from a happy customer: * good packaging, fast shipping, great PCBs! * Mouser BOM link included (saves a few hours!) Thx again! Many greets, Peter

XMAS near and lotsa sleepless nights - will take it (including MCU) :) PM sent :) Thx + Many greets! Peter

SEQ with Wilba PCB assembly issues - buttons not working :(
Hawkeye replied to keves's topic in MIDIbox SEQ
Congrats and enjoy that SEQ V4 - the best hardware sequencer on this planet (R) ;-) Many greets, Peter -
Super - sie werden Dir taugen - ich hab meine gestern Nacht mal reingelötet und getestet - Funktion wie gewünscht und sie haben ein angenehmes Klickgefühl :-). Ciao, Peter

It would be way easier to just desolder the currently installed resistors (next to the central wheel encoder) and solder in a higher resistance. E.g. if these are 220R resistors, try 1K... after opening the SEQ up, desoldering and resoldering would take about 10 minutes, the software approach, while theoretically possible, would take a LOT longer and you would have a non-standard firmware afterwards :-). Many greets and good luck! Peter
