You're right. We already sold this to Microsoft. Better luck next time.

OK, you inspired me to go get a 32-key MIDI controller. It will take me about a week to figure this out!

I'm not sure I understand your question.

My midi controller is connected right now and messages are coming in.

I activated your script and i understand that i need to press something (F1?) and see if it capture something?

No, You have to press midi buttons and see msgbox in ahk.

I'm just speechless Mikey! You have no idea how much I appreciate the fact that you are being a sport when it comes to my ignorance.

I KNOW THAT YOU ARE BOTH RIGHT and probably you both understand and got it to work, but if I don't have a step by step of what EXACTLY I need to be doing for you to assess whether it works or not, it will be challenging

I speak fluent Hebrew and English but when you dominate code you tend to speak like a coder and my brain is detecting it like a new language. Try to guide me like this:

1. Download this script, copy paste, and run it
2. Enter the script and inline xxxx change it to the name of your midi device
3. open a folder and press on F3,F3,F10
4. Hit your controller
5. Does it responds? Did you notice a message coming in?

Something like that.

I promise you guys I can follow directions very well but with specificity

Ok, that's a specific command i can follow! Yeh!

I understood that there's a line in the script called msgbox where the midi message is suppose to appear?
Ok, i can do that

1. Run the script
2. Hit a key on my keboard
3. Enter the script to see if there's something appear in the msgbox

Standby...

Run this script.
Hit your controller.
Do You see any messages?

Yes Sir!!!! Something came up!

I ran the script and hit a regular key, any key.

This message comes up (see attached)

Posted: **03 Nov 2020, 18:18**

Why do You have error in second message box?
What is written there?

Posted: **03 Nov 2020, 18:23**

Sorry for that.

Here you go...

Posted: **03 Nov 2020, 18:26**

I had a lot of programs running in the background. LOOPmidi, Midi-osx. Misi2key

I closed everything and this is the message that appears

Posted: **03 Nov 2020, 18:33**

Try to restart computer.

Posted: **03 Nov 2020, 18:42**

Same behavior.

The same message comes up. But it does respond to the midi press on my keyboard.

Here's the whole action

Strange, but OK.
I combined mikeyww code with mine.
Change path of ini file to Yours
Then select any file, press f3
Hit your controller
after that You should see key name in inputbox
Press OK.
Hit your controller once again - file will open.
To delete key of you controller - select any file press f3, hit controller button that You want to delete, and write "DEL" before or after key in input box.

I'm very excited to try it.

Before I do, one final question because I didn't get it before:

What is INI file? Where is it located?

I understand how to change the path in the script but I still don't know where is it by default?

Posted: **03 Nov 2020, 20:38**

It is configuration file.
It can be at any location.
If ini does not exist, script creates it.

Posted: **03 Nov 2020, 20:39**

Got it!

Trying it now.. Fingures crossed

Posted: **03 Nov 2020, 20:43**

This is the message that i get - error message

- The script excute without errors
- F3 pop up open
- Midi is receiving - a midi message

Upon hitting OK - the error message appears

Posted: **03 Nov 2020, 20:44**

I don't know if this is related but out of curiosity i checked the target folder i placed for the INI file ---> C:\Users\eladb\Desktop\TEST

I saw that no file was created

Maybe i should change to lower case folder name?

Didn't work, same error message appears

Posted: **03 Nov 2020, 20:51**

May be there is no folder test on desktop?
