Hi, it’s possible add the midi out/thru?

Great project!
I got hooked on it right away.
But for my use it has a problem which is:
when many messages arrive it is unable to react. This can be seen when I use the fader on the midi controller.
For some reason I concluded that it lacks processing power and (or) a hardware serial port.
Would I get your permission to adapt this code for ESP32, with my humble knowledge?

Sorry, I wasn’t using the right libraries, that’s why I was getting errors. Thanks

Hey! Please read the instructions on my page. You have to install those libraries in your Arduino IDE; you can find them in the library manager.

Hi, Great project, I downloaded the MIDI_Switch_v12_2020-10 project and it seems that there are no files #include „OneButton.h“, #include „SSD1306Ascii.h“ and #include „SSD1306AsciiWire.h“ is this normal?

Thanks for help

Hello! Great design! My question is – can I use let’s say D13 for the MIDI IN signal instead of D12 so I can use that pin for another function?
In the code there is a info line saying „only RX is needed; set RX = TX pin to save one I/O pin“. Does that mean I can use one of those for the MIDI IN and have pin D12 unused?
BTW for context – I am using an Arduino UNO to program a DIP28 chip and put it directly in an amp design that has a lot of functions that I want to make switchable via MIDI. So far I relocated the indicator LEDs to analog pins to free-up D10 and D11 but will be awesome if I could free up D12 as well. Cheers and Happy New Year 2024!

Hi Jens !
I have been building and using your Arduino and PIC midi switches with my FCB1010 for quite a few years now with great success! Thank you so much for your brilliant design! More recently I have been using my Kemper a lot more often and have now upgraded the FCB1010 with the Uno4Kemper software which uses both midi in and out 2 ways from the Kemper to the FCB for full functionality – however I would still like to use your switch for some external looping etc… I think the Uno4Kemper is doing something strange to the midi control – do you have any experience for this? The v12-2020-10 software will not see the PGM or CC at all (other than midi LEDin LED blinking) and the v10-2020-04 will only work unreliably (sees about 50% of program changes). I would be grateful for any advice on tweaking the s/w or h/w on how to get it working again reliably!
Thanks again!
Dave

Als Antwort auf Will Powell.

Hey Will, actually I’m working on a tempo related project: an external MIDI tremolo that sends volume control change messages via MIDI to my Eleven Rack, in order to create a tempo controlled tremolo/slicer effect – the „unique“ function is a footswitch that enables me to re-sync the tremolo effect to the beat, because when playing live there is always some slight tempo deviation, even if the drummer is on a click. But that is not what you are looking for 🙂 Anyway, when starting my project I had a brief look at the MIDI tap tempo specification of my eleven Rack. Tap tempo control via MIDI is done with control change messages; I do not know if this is some kind of standard and how other devices deal with this. As the MIDI switch can convert CC messages to switch outputs, this may be the basic principle to deal with this, but most likely it will not be an ideal setup (mechanical relay not the best solution for this, and maybe you will get unwanted dividers (quarters, eigths, etc.)). If you have any MIDI device that can be configured to send tap tempo CC messages, you can test the basic functionality and see how it turns out.

Working on a version of this that would fit in a Gorva C65 w/4 switches. Would love to figure out how to add a midi clock -> analog tap tempo output for controlling non midi gear (delays and modulations). Is this something you’ve looked into by chance?

Will report back on the success of the 4x switch version. Thanks for posting and definitely put up a donation page!
