  2. MB808 seq for MB808 voice

    in MIDIbox SEQ

    Posted · Edited by Shuriken

    As Shuriken said, wouldn´t it be possible to use pcbatterj/Jef/Synthage.com ´s 9090 MBSEQ V4 based sequencer board for the 808 voice boards, too? The design looks very nifty and it "only" needs to trigger the analog voices?

    Edit: ok, there´s things like note accents, too - I think they are triggered via additional trigger channels...

    You´ve gotta love the euclidean rhythm generator in the V4 SEQs, a great addon for any drum sequencer...

    Many greets!

    Peter

    I think the 9090 can only be controlled via midi.

    Like Antix, i will be waiting for this one.

    MB808 seq for MB808 voice

    Hello i m trying to make th MB808 with the microlarge PCB.

    I have finish the 3 boards , i have also building power supply, and output from yoda design.

    Now i will building the sequencer part, for that i have 1 x MBHP_CORE, stuffed with PIC18F4620, 2 x MBHP_DINX4 amd 2 x MBHP_DOUTX4.

    I will also building the banksitck

    I know that TK and Kogz23 works on a new "combined" PCB

    I wanted to know this standalone MB808 seq have the same design as MB808 with the digitast switch and what is the difference between this MB808 seq and the MB9090 seq from jozef ?

    I need also some help for connecting switch and led to DIN and DOUT :)

    On the original MB808 there is a pot swing (10KB) and accent (10K) where there are connecting ?

    I assume with the MB9090 seq, you mean this one:

    gallery_8996_152_12242.jpg

    That one is based on LPC17 Core and is with custom app. TK is adjusting his (PIC) Core8 code to make this possible. The upside on that is that you will have supported code :wink: ATM I don't think there is more info available on the combined pcb TK and Kogz32 are working on.

    Connecting leds to DOUT4

  9. TDA1543 DAC-based I2S board for LPC17?

    Hi,

    I see a similar notice on the TI website for the PCM1725

    "Not Recommended for New Design (NRND)

    Replaced By PCM1754 – The device has the SAME FUNCTIONALITY as the compared device, but is not pin-for-pin equivalent and may not be parametrically equivalent."

    Anyways, thank you for this community. Still learning about all that is happening here.

    It might have something to do with the fact that fuzzylizard's post is more then a year old :wink:

  11. Adapt the MBHP MIDI USB source code For PIC18f14K50

    in Parts Questions

    Posted · Edited by Shuriken

    Yes I do mean the MBHP USB PIC firmware.of course it is reliable. I personally tested that with different MIDI gears; using different USB expansion boards and hubs, and it works just great. Like a professional M-Audio interface. Pic18f14k50 is way cheaper and has a smaller package respect to 18f2550.

    it makes the whole thing to be smaller and more economic! I'm already working on this but I definitely need others help.

    Ciao!

    TK has put quite a lengthy explanation on the project page. The GM5 was the prefered solution (until the ARM boards arrived). But i wish you good luck on your endeavor.

  14. MIOS upload without Studio?

    in MIDIbox Tools & MIOS Studio

    Posted · Edited by Shuriken

    Thanks for the quick reply. Yes I have seen it (mios32_toolchain) and tried without success to build the thing, unfortunately it fails.

    (comes up with the message: make: arm-none-eabi-gcc: Command not found, although I entered MIOS32_GCC_PREFIX=arm-none-eabi.)

    I would have loaded an old pc with Windows XP (this works fine with Studio) but the disk got lost some time ago, and

    I am stuck with everything Linux.

    It has been some time since I played around with MB and I cannot recall how I got the thing running after burning in the boot loader.

    Thanks again.

    Mios32 toolchain is for compiling application. MIOS Studio for Linux this is for uploading apps.

  18. Lost documentation for Core8 sysex implementation

    in MIOS programming (C)

    Posted · Edited by Shuriken

    Greetings,

    I have an 18F Core8 project that includes a 2X20 character LCD display.Tonight I went looking for the details on how to format a SysEx message thatwill display text on that display.I did it before, but can't find the utility I wrote.

    I checked the WIKI, and didn't find much. (maybe I did a bad search?)I checked uCapps, and found a link to the document I need!http://uCapps.demios/mios_sysex_implementation.txt

    Sadly, the link only leads to a 404, file not found.

    Any suggestions on where I can find this information?

    Thanks,LyleHaze

    It's there on: MIOS8 Download > mios_sysex_implementation.txt

  21. AOUT redesign

    in Design Concepts

    Posted · Edited by Shuriken

    The bipolar option does not require any reprogramming. The circuitry is slightly different. But the values to be set in the register are the same as for unipolar. Just the resulting output is different.

  22. AOUT redesign

    in Design Concepts

    Posted · Edited by Shuriken

    No, your proposal is sound in theory. However, you need to check if the DAC itself is designed for uni- or bipolar operation, if there's a reference that needs to be applied etc. I haven't studied the MAX525 in detail, but some checking would be prudent.

    According to the MAX525 datasheet, it can be used for bipolar operations. The internal register works a bit different then. The register is set by the software (if you compile it with the right aout module)

    Edit: The settings of the internal register correspond to different output values in bipolar mode.

  25. [S] MIDIBox gear LCD windows fromSchaeffer

    in Fleamarket

    Posted

    I'll take 2 MB6582 windows and one MBFM window.

    I am a little curious why the windows for MBFM and MBSEQ are different; they are both for 2x40 LCDs? Or did the cutout for the MBSEQ get different dimensions?

    If you actually checked the fpd you would see the dimensions and corner radius is different. The next question probably is, why :wink:
