    Also, just noticed these SDcard errors in the startup log, I can move this discussion to another thread if I am cluttering this thread with useless troubleshooting... :thumbsup:

    Thanks for the help TK!

    I created the /SESSIONS/DEFAULT/MBSEQ_C.V4 file manually with the one value you noted.

    After that I proceeded with what the change log says.

    Still not working on MIDI out 1 sadly, but you've giving me some more info as to what needs to be configured, so I thank you greatly for this education. I will play with this some more and see if I can get it working.

    I took the mini SDcard adapter route, because I really would like to in the end not attach a computer to this setup. I had a 4GB & 16GB FAT32 card around the house to try. For some reason, not all the files are able to be created on my SDcard? (Tried both). I will reformat the 4GB one and see if that has a different result.

  5. MBBLM on iPad via Lemur

    in MIDIbox BLM

    Posted · Edited by peterpressure

    So I loaded "MIDIbox SEQ V4.058" on my LPC17 with no sequencer or anything, just the core, not even an SD card.

    I power up the core and get the ip address from DHCP:

    IP address: 10.103.24.107 <- My core IP to use in Lemur

    I then set the following in MIOS studio per the change log.

    set osc_remote 3 10.101.80.121 ->my iPad

    set osc_local_port 3 8000

    set osc_remote_port 3 8000

    set osc_mode 3 1

    set blm_port OSC3

    store

    Start the Lemur app and it connects and I can hit Start/Stop or keyboard mode and I can see the MIDI commands input into MIOS console.

    Now how do I route this to the MIDI output of my core to my synth? Do I need to set router X in MIOS or do I do this in Lemur?

  7. Power over Ethernet to LPC17

    in Parts Questions

    Posted

    So I finished my first LPC17, but I have another one almost finished and I was wondering, could I remove jumper J17 and wire pins J1 to the MagicJAck Ethernet somehow to use power over ethernet?

    That way I could just use one cable to my synthesizers to send MIDI data to and eliminate the USB or external power.

    Something similar to this but standard PoE: http://shop.tuxgraphics.org/electronic/detail_avrwebserver5_poe.html

  8. Problem while building my LPC 17

    in Parts Questions

    Posted

    Well I am a little ahead of you, but it is actually very simple.

    From the build page:

    Note that USB Power Jumper J17 has to be removed when the core is supplied externally via J1!

    Plug in the USB cable, and mount the "USB Power" jumper on J17.

    Measure 3.3V between GND and the 3.3V supply pins to the LPCXPRESSO module.

    Here is the LPCxpresso schematic in this PDF: http://ics.nxp.com/support/documents/microcontrollers/pdf/lpcxpresso.getting.started.pdf

    You are looking for VIN, I believe it is J6_2 on the LPCxpresso board.

    Any ground should do.

  11. Let`s go for my first midibox DIY - BLM

    in MIDIbox BLM

    Posted · Edited by peterpressure

    With regards to a BLM & BLM Scalar PCB. Find bhudda started a bunch of good work here (and already corrected his mistakes): http://www.midibox.org/dokuwiki/doku.php?id=findbuddha

    I was working on a proper BLM Full PCB without the center gap based on his design I posted here: http://www.midibox.org/dokuwiki/doku.php?id=peterpressure

    Your welcome to use those for your PCB design, we used KiCad and I want to help however I can because well, I want a BLM too!!!

  13. LCD J15 port on MBHP CORE LPC17

    in Parts Questions

    Posted · Edited by peterpressure

    I know the MBHP CORE LPC17 build guide mentions this, but I just wanted to confirm.

    http://www.ucapps.de/mbhp_core_lpc17.html

    The pinning of the 2x8 LCD connectors J15A and J15B is mirrored to simplify the cabling of common 2x20 and 2x40 displays (and partly due to historical reasons - it's originated from the so called "UltraPCB").

    Note also that in difference to the MBHP_CORE_STM32 module, the J15 ports have been rotaed by 180 degrees! But the polarity is the same, which means that you can re-use the LCD cables which you made for the MBHP_CORE_STM32 module.

    What exact orientation does my J15 header go in? Pin 1 is bottom right on the PCB from SmashTV, but the header itself says Pin 1 is bottom left if the keying is facing down. See picture below:

    Almost done with my first core!!!

    Ckeck your browser, works over here.

    Even tried it on my Android phone.

    I just get:

    Although not a full blown kit, there is something similar going on here:

    Link does not work for me?

    I am stumped, I tried 3 browsers on 2 computers...

  23. Raspberry PI board

    in Miscellaneous

    The 26 GPIO headers will be plenty enough to interact with the modules?

    there are enough IOs available to connect commonly used hardware extensions (DIN/DOUT/LCDs/AIN via SPI/AOUTs - even MIDI could be made available via the "debug console" UART)

    Accordingly a migration of MBSEQ V4 is feasible.

    Would a first step be getting FreeRTOS working on an ARM11 proc? http://www.freertos.org/index.html?http://interactive.freertos.org/entries/449231-s3c6410-using-rvds-tool-chain

  25. Midibox Piano Synth?

    in Design Concepts

    Posted · Edited by peterpressure

    Editing this post as I reverse engineer this midi piano...

    I have some extra parts from a cheap 88-key midi keyboard.

    The keyboard has been having some issues so I opened it up to see what is inside.

    It uses an "NXP LPC2101" mcu to transmit keyboard data via an SPI serial interface to an "NXP LPC2136" mcu then MIDI out.
