    A downstripped MBHP_CORE_STM32F4 module in Eurorack format would be nice-to-have as an alternative solution to the Euroreceiver - maybe with a SCS (6 buttons, encoder, display) - this would allow to run MBCV which gives us a lot of LFOs, Envelopes, sequencers, modulation matrices, etc.

    As mentioned by Christian, there was no special reason why assigned DIN and DOUT SR #9 to the DIO function.

    I thought this might be better in case you would like to add more physical SRs in future, no need to change the IDs again until you reach #9. If you don't like this, you could also use SR #3, but not SR #1 or SR #2, because these positions are already allocated by the scan matrix.

    Btw.: the most simple way to find out the hw_ids is to enter "set debug on" in the MIOS terminal, then trigger the buttons and observe the debug messages in the terminal (doesn't work with LEDs of course, but if you know the button position, you can easily conclude on the LED position)

    Yes, there is a conflict with the shift register assignments.

    Try this one: 

    # now enable DIOs (0 = input / 1 = output)
DIO  port=J5AB  emu_din_sr=9  emu_dout_sr=9  output_mask=01010000

# button events (DIN SR1 pins are assigned to hw_id=65/67)
EVENT_BUTTON id=65  hw_id=65 type=CC chn=1 cc=16 range=0:127  fwd_id=LED:66
EVENT_BUTTON id=67  hw_id=67 type=CC chn=1 cc=17 range=0:127  fwd_id=LED:68
#EVENT_BUTTON id=65  hw_id=65 type=Meta  meta=RunSection:1  button_mode=OnOnly
#EVENT_BUTTON id=67  hw_id=67 type=Meta  meta=RunSection:2  button_mode=OnOnly

# LED events (DOUT SR1 pins are assigned to hw_id=66/68)
EVENT_LED    id=66  hw_id=66 type=CC chn=1 cc=16 range=0:127
EVENT_LED    id=68  hw_id=68 type=CC chn=1 cc=17 range=0:127

    Best Regards, Thorsten.

    No, don't worry, outputs are protected against shorts internally.

    Just tried your configuration, it works after changing fwd_id=LED:3 to fwd_id=LED:2 (we always forward to a hw_id) 

    RESET_HW

# J5A PORT SETUP
# J5.A0 -> octave up switch
# J5.A1 -> octave up LED
# J5.A2 -> octave down switch
# J5.A3 -> octave down LED

# now enable DIOs (0 = input / 1 = output)
DIO  port=J5AB  emu_din_sr=1  emu_dout_sr=1  output_mask=01010000

# button events (DIN SR1 pins are assigned to hw_id=1/3)
EVENT_BUTTON id=1  hw_id=1  type=CC chn=1 cc=16 range=0:127  fwd_id=LED:2
EVENT_BUTTON id=2  hw_id=3  type=CC chn=1 cc=17 range=0:127  fwd_id=LED:4

# LED events (DOUT SR1 pins are assigned to hw_id=2/4)
EVENT_LED    id=3  hw_id=2  type=CC chn=1 cc=16 range=0:127
EVENT_LED    id=4  hw_id=4  type=CC chn=1 cc=17 range=0:127

    As you can see, I also added "RESET_HW" to ensure that previous settings are undone.

    The LEDs shouldn't be dimmed.

    Best Regards, Thorsten.

    Based on my experiences with MB808 the trigger width is crucial, therefore I can fully understand Andrews request that a digital option is desired.

    The "pipeline based approach" is working fine, we can now adjust the width from 0 (=off -> gate function) to 10 mS 

       o DOUT_1MS_TRIGGER in the MBSEQ_HW.V4 file has been replaced by a configurable trigger width which
     can be adjusted in the CV Configuration Page with GP13 now

    -> http://www.ucapps.de/mios32/midibox_seq_v4_096_pre7.zip

    It would be great if everybody could help to test this new firmware version, regardless if the new CV features are used or not (I hope that nothing else is broken!)

    I would like to create a final v4_096 release, because v4_095 is from last december, and it started to smell! ;-)

    Best Regards, Thorsten.

    New version can now be found here: http://www.ucapps.de/mios32/midibox_ng_v1_037_pre4.zip

    It's now possible to mix input and outputs on a single port as shown in this example: https://github.com/midibox/mios32/blob/master/apps/controllers/midibox_ng_v1/cfg/tests/diocfg_3.ngc

    And J5 is supported as well (called J5AB) - it's even possible to mix digital with analog functions -> https://github.com/midibox/mios32/blob/master/apps/controllers/midibox_ng_v1/cfg/tests/diocfg_4.ngc

    In your case, please keep the analog pins disabled

    Best Regards, Thorsten.

    Wow, amazing! Are the CVs distributed out on J19, so the same RC1 channel or is RC2 used as well to double the transfer rate? What is the maximum data rate?

    The data update rate is only 35 uS for all 4 modules, so no need to make it more complicated :)
    That's also the reason why I enabled all 32 channels by default, it doesn't make a big difference.
    Using a second CS line wouldn't help, because SPI transfer time would have to be consumed anyhow.

    Is there a functional way to use all 32 CVs with only 16 tracks? Polyphonic tracks?

    With channel 9-13 you can route note and velocity value to two CV outs - in this case you need all 32 outputs.
    But you can also route CCs of a track to the CV outs (starting at CC#16 as far as I remember...)

    Is it possible to set (or preset) the drum trigger length to something longer? This is already available for the clocks but I couldn't see an easy way to do it for triggers.

    Actually I looked into this, but there is a technical problem.
    The 64 drum triggers are currently cleared with each SRIO update cycle, this was very pragmatic and effective and especially doesn't consume resources (counters) and CPU time (processing the counters)

    For individual delays I would have to implement counters for each trigger, and this is very costly.

    And for a single delay we would potentially run into the problem, that each mS a new trigger could reset the counter, leading to "stretched signals" for all triggers for which the configured time already passed...

    Best Regards, Thorsten.

    New major enhancement available for MBSEQ V4+ users - up to 32 CV channels and gates! :-)

    -> http://www.ucapps.de/mios32/midibox_seq_v4_096_pre6.zip 

       o Only for MBSEQV4+: support for up to 32 CV outputs (and corresponding gates).
     Means: up to 4 AOUT modules can be chained.
     Tested with MAX525 (and midiphy Eurorack Expander), but should also work with TLV5630 based AOUT_NG
     The additional CV outputs can be accessed with MIDI port CV2..4.

   o AOUT port has been renamed to CV1..CV4

   o Utility Page, GP Button #11 now changes to the CV Configuration Page

    Best Regards, Thorsten.

    my idea was to indicate with lower (if OFF),and upper(if ON) cases of first letters of each effect ,ECHO=E,e ,Humanizer=H,h and so on

    i feel this can save a lot of time running around

    here little example

    letters are not exactly in place,but just to visualise

    midi.thumb.png.ba78810c58da8e8e26adb9a98

    still relevant or just a quick idea?
    Will lead to some effort at my side... therefore I would only add this if other people find it useful as well

    hi everyone

    a quick proposal here

    ON\OFF for MIDI MMC messages per port?

    maybe in BPM menu?

    for example some synths have sequencer without MMC filter

    and in result when you hit play on Midibox, synth sequencer also starts

    this might be undesired situation.

    thank you for great work TK.

    bests.k

    I guess that you mean MIDI clock/start/stop (MMC isn't supported)
    They can already be enabled/disabled for each MIDI port in the BPM menu

    Best Regards, Thorsten.

    I used the latest release (midibox_seq_v4_096_pre5) on an LPC17 core. The beat led doesn't flash on the first step of the sequence. So I get 3 flashes in a 16 step loop.

    If I set the track synchronisation to 32 steps, the beat led flashes normally on measure step 17, but doen't flash on step 1. So I get 7 flashes.

    Release midibox_seq_v4_095 works without the above problems.

    Fixed in v4_096_pre6

    IO Pins are not initialized in your pseudo code.

    But regardless of this, it will result into the problem that the MBNG application will overwrite IO configurations from different places - and even if we find quick&dirty hacks which avoid such overwrites, you would have to re-do the changes whenever a new firmware version is released.

    Therefore I recommend to go the common way and to use the existing app like it was intended.

    Alternatively I could consider to natively support J5 as digital IO in a proper way (which will require changes at many places that I've to work out by myself...)

    Best Regards, Thorsten.

    Thanks a lot Andy and Peter for this great work! :cheers:

    Based on this video tutorial I built up my modules yesterday, all are working fine, almost no troubleshooting was required. :)

    midiphy_modules.thumb.jpg.972e7328aec6d8

    Now I need a case (I ordered a 4ms Pod40X in the hope that the modules will fit into this case without special measures)

    Best Regards, Thorsten.
