Here is what I get:

I disabled all MIDI out ports before I made the test. Anyway, if MIDI out is not disabled, the result is the same but the crash was at channel 7, so I don’t thing it has something to do with a paticular channel.

I will add a picture at the weekend

Hi @uli!

What image are you using? It’s an official Gorgona or an experimental ZynthianOS image?
Is it updated to the last?

Sorry, but as a musician I’m in the learning stage and I don’t think, that you like to hear my voice . My expierence in programming is also not so high. I normally have to program on windows. But I plan to install a development environment.

I’m using Gorgona. I will get myself a second SD an test the experimental image.

[wyleu]

Don’t worry, it’s really all a community building effort and as someone who is enough of a musician to know how good real dedicated musicians are, it need to be nothing more than one note from a patch that you like, or perhaps don’t like.
At the end of the day the zynth is a musical instrument and it deserves to have it’s voice heard by fellow like minded souls . . . .(*)

An extra connector for some extra switch :

Test is OK :
CH#00 CONTROL_CHANGE 81 => 127
CH#00 CONTROL_CHANGE 81 => 0
CH#00 CONTROL_CHANGE 83 => 127
CH#00 CONTROL_CHANGE 83 => 0
CH#00 CONTROL_CHANGE 80 => 127
CH#00 CONTROL_CHANGE 80 => 0
CH#00 CONTROL_CHANGE 82 => 127
CH#00 CONTROL_CHANGE 82 => 0

Great feature, these configurable extra switches

Remains to build the pedal board and to make a sound sample

[jofemodo]

Very good idea to use a DIN-5 connector for it!! Congratulations!!

Please, could you give some details about the configuration (webconf) and add some photo of the wiring, etc.? I’m sure that other @zynthianers would find it very useful !!

Thanks!

[MrDham]

Yes, I started another topic for that:

An extra connector for some extra switches or pedal board

An extra DIN-5 connector for some extra switch or pedal board on my zynthian V2.1 Kit with all-in-one board : [image.jpg] you need to solder a connector at sw1 on all-in-one PCB: [image] You need to drill a 16 mm hole in the zynthian box (and two 3 mm holes depending on your DIN connector): [image] A challenge by itself… *** Of course, step 1 and 2 require some disassembly *** Make a cable [image] I used this kind of connector at PCB side: [image] And a 5 pins DIN connector: …

Hi Jofemodo,
I read your thread from dez 1st 2018
how to i stall the sustain pedal and the panic button.

I do not know how to solder a “5pin connector” at the allInOne board.
In my Zynthian I see the flat cable and the connector is as long as there are pins.

Whats to do?

[wolfpaw98]

Which Zynthian version do you have? The original all-in-one board did not have the 5 pin breakout for the extra switches. These were added in the updated all-in-one board. Extra switches can, however, still be added to the original all-in-one board by soldering wires directly to the pins on the MCP chip. This is what I did. I’ll post some photos of this when I get home tonight.

[jofemodo]

Have you read the wiki?

http://wiki.zynthian.org/index.php/Adding_Extra_Switches

Regards,

[Micki]

thanx, yes photos are great. I have no plan.

Now I have 2 Zynthians.

The first one is a raspi 3 and i want to build it in my livetime projekt.
This is a Böhm CNTKeybed in a DX7-case with a Böhm 12/24 expander. When this Zynthian has a sustain-pedal, I have a small setup without missing sounds.

[Micki]

The second one is a raspi 4 with a 5"hdmi monitor and a behringer UCA222 2x2 Interface. without knobs and faders. I try to play it without an own ui, just using the control channel and notes on the keyboard.

I don’t know how to add fotos, excuse Problem solved, thanx!

.

[Micki]

Excuse me, sometimes I need time.

Yes I read it.

A picture shows the aio connector with 5 pins cross to the long connector. Ok
But what is with the switches?

I need the sustain pedal and the panic button. What numbers do they have? I think, the others are for further purposes.

The wires for sustain pedal will end at fem jack at the case,
and the wires for the panic button will end at a switch.

The I have to edit the webconf entries.

I hope thats right.

Thanx for your serenity and helping.

[jofemodo]

@Micki

But what is with the switches?

From the wiki:

Connect some kind of switch between pins 2-5 and pin 1 (GND). The switches are normally open, closing to pin 1 (GND).

[jofemodo]

@Micki

I don’t know how to add fotos, excuse.

Click the “upload” button on the editor topbar. It’s the 7th from left.

[Micki]

Thanx!

Sidenote/question: how faulttolerant is the os for just yanking the poweradapter out (as turning off zynthian)? Preferably a switch/button to call for shutdown-command would be nice. Maybe its already been implemented, in that case sorry for my ignorance
