[midiphy Eurorack Expander Modules]

Thank you for your interest Thorsten,

The thing is that If Andy decides to create his version, I will stop mine, cause there's no space for 2 different core euro modules which have the same purpose. Until yesterday I was sure to do it because nobody told he wanted to, now I don't know.
That's the reason I insist and try to convince him, more than that if Andy decides to play this game with me, quantity will drastically decrease the price, of course.
Anyway I will provide the platform to both of you as soon as I can, for you to decide after that ;)

Best Regards
Bruno

It's a compromise of using pre-fabbed MCU breakouts and avoiding fine-pitch SMT, as it can be difficult sometimes as we've seen!

DipCoreF4 will be assembled too, all tiny components(except pinheader and mini-USB) will be mounted. For less quarter size of the wCore. In fact DipCoreF4 + DipBoardF4(full platform) is smaller than the wCore alone.
The only differences are:

• No J10A/B.
• No Parallel J15 only serial(with 2 CS lines).
• 2 leds instead of 4.
• Two USB, one DEV, one HOST.

My version of the MIOS32 is already works with it and still works with the wCore, Disco etc...
I really think you should consider it one day cause you could like it ;)
I will send some on next batch, to you and Thorsten as you can evaluate it.

Best regards
Bruno

very nice! Does it provide J8/9 and J10A/B?

J8/9 of couse! No J10A/B
Here the available ports.

A downstripped MBHP_CORE_STM32F4 module in Eurorack format

I'm working on something like this, I try to do not exceed 50mm depth. I need it for the HAARP,

And adapt the SCS to the euro format is also a good idea, @latigid on ?

I plan to create another CS based on the work I made for @Phatline with a pot for each parameter and TFT screen, like I did for the HAARP.

[MIDIbox SEQ V4 Release + Feedback]

Hi!

You can maybe do it yourself, by changing the order of the elements in seq_scale_table to your need and recompile the app...
It's in this file:
https://github.com/midibox/mios32/blob/master/apps/sequencers/midibox_seq_v4/core/seq_scale.c

[MIOS32 app configuration for the embedded DAC's pinouts? (Discovery board)]

You're right DAC_OUT of the STM are on PA4 and PA5.
MIOS32 does not support STM DAC functions, only ADC via MIOS32_BOARD functions.
But you can initialize these 2 pins yourself.
Take care if PA4 is used by J5A for ADC, PA5 is used for MIOS32_SPI0_SCLK then you have to stop this SPI port by using MIOS32_DONT_USE_SPI0 in the config file. MIOS32 J16 SPI port will not be usable anymore, means no SD card for example.

And this is what v2 will be . Sorry Bruno!

Don't be sorry! It's a good news even for me. The OLRE16 is far to be ready. In the order HAARP first, then Bandmaster, the MB2069, then the OLRE16. So ;)  ....

[C3 with diff vel. 2 diff. notes]

You're welcome ;)

No it will not "struggle" but, this is just a way to handle the DOUT from MIDI Input, not to play something from a midi file. But this last thing is also possible.

Anyway this is very cool and fun :)

Best regards
Bruno


 

[C3 with diff vel. 2 diff. notes]

I don't know running MIDIO128 but with a basic app (traditional) this is not complicated

// This hook is called when a MIDI package has been received
/////////////////////////////////////////////////////////////////////////////
void APP_MIDI_NotifyPackage(mios32_midi_port_t port, mios32_midi_package_t midi_package)

  // check the note
  if( ((midi_package.event == NoteOn)||(midi_package.event == NoteOff)) && (midi_package.note == 0x3c)){ //only note C3
    // clear velocity if note Off
    if(midi_package.event == NoteOff)midi_package.velocity = 0;
    // check velocity
    switch(midi_package.velocity){
      case 0:
        MIOS32_DOUT_PinSet(0, 0);
        MIOS32_DOUT_PinSet(1, 0);
        MIOS32_DOUT_PinSet(2, 0);
      break;
      case 1 ... 64:
        MIOS32_DOUT_PinSet(0, 1);
      break;
      case 65 ... 96:
        MIOS32_DOUT_PinSet(1, 1);
      break;
      case 127:
        MIOS32_DOUT_PinSet(2, 1);
      break;
      default:
      break;
    }
  }
}

[Trigger Outs - 4ms]

Same!
It seems the DOUT triggers can be enabled in the hardware config file by "DOUT_1MS_TRIGGER" then the variable seq_hwcfg_dout_gate_1ms is set from this text command but I don't find where this variable is used, so I can tell how this is used, even less how to change its length.
I think we have to call @TK. for that, he's the only one who can explain how and what is doable.

Bruno

[Trigger Outs - 4ms]

Or a 74HC123, anyway, I don't know how, but I'm sure there's a way to set the drum triggers out of the Seq V4 to 4ms instead of 1ms.
Maybe ask here:

But first, did you already try your module with the 1ms triggers?  ;)

[Troubleshooting midiphy SEQ v4+]

In complement for an external power supply and USB power management.

With this circuits the external power has priority over USB power.
It works fine cause this is the one there is on all arduino uno board, so well improved. And I did the same thing on the dipBoardF4 external power module and use it.

There is no power switch, as you should typically ensure a stable power rail before connecting data and the solution to that was a bit to complicated. Imagine if it was already connected to your computer with data being sent but no power rail because it was switched off. I'm honestly not sure if this would be a problem for the SEQ or the computer.

Hi, there's no problem with that. 2 cases, device says "I'm here!" or host polls something like "are you here?"... In both cases the device always waits for a stable power to say something. No need of a complicated solution.

[Adding CS-line to AINSER8]

swap!

[Adding CS-line to AINSER8]

Did you invert the 2 last modules?

 

[Adding CS-line to AINSER8]

ok. And physically, did you check the cs lines with the oscillo? you should see a periodic pulse.

[Adding CS-line to AINSER8]

Hi Chris,

Do you test it without the NG with a regular app first?
Can you share the code you change in MIOS32, whole AINSER files?

By using highend dual track motor fader with one servo track (linear taper) and one audio log track

Yes obviously
So @totoRaymond you will need single linear track moto-fader ;)

Zam

really? then how do you get the position from the faders?

You use 'dual taper' fader, one for the audio and the other for AIN?

I'm aware of Zam's Project, but as I understand it, it's more of a way to automate existing analog desk.

It's the same, I'm not sure but there's no audio signal passing thru his faders, there's surely VCA for that purpose, the part that you don't need. But you will need faders, motor control etc...

Best!

[MidiBox DAW Controller]

Bienvenue totoRaymond
Sacré pseudo! ;)

I hope @Zam will not blame me for quoting him here again, but he already has a project that looks like yours, except that his is already well advanced, take a look at it,
 

Good luck anyway and have fun with your midibox stuff!

Just now, Thomasch said:

Ups yes, that was a typo, i meant Vs, i will fix it in the original post.
It's not a bad idea, to include the DIN/DOUT directly to the frontpanel pcb. But on the other hand, i have DINX4/DOUTX4 boards still in use with the actual setup of my MIDIbox FM, so no need to build it again.

 

Better too if you're happy with it and want to share a few. Cheaper for everybody, and just the price of some cheap components more for you. SO package on bottom side sounds good for your CS.
