Hello.
Please help me configure the module.
I’m trying to make triggers to control my Blackmagic ATEM mini using a MIDI controller.
I create a trigger like this
Events - On condition becoming true
Condition - generic-midi: Receive MIDI Message - Note On (tried Note Off)
I’ve tried different midi channels, tried different notes, tried Use Variables - it doesn’t work.
The indicator button shows that a MIDI signal is coming, the log shows that the MIDI signal is received (there is a note) - but nothing happens.
If I change Condition to Message Type = CC - everything works! But my controller has only 4 buttons that allow you to send commands like CC.
Please help me set this up.
- Note on the log
In my controller, the buttons were set to channel 1. When I first connected it, when I pressed the button, the log displayed a message
> **debug** : Received: noteon Message, channel: 0 (0x00), note: 0 (0x00), velocity: 127 (0x7f) from “STARRYPAD”
>
> **debug** : Received: noteoff Message, channel: 0 (0x00), note: 0 (0x00), velocity: 0 (0x00) from “STARRYPAD”
The channel was defined as = 0.
When I changed the controller settings and set the channel to 2, it started showing up in the log as = 1.
Although, when setting up a trigger with the CC command and viewing the variable, it displays the correct channel, number 2, in messages.

Hello and Welcome;
Have a look at this video and the thread, you may have to do something like that. Let me know if that works for you.

> Ok, thanks to a suggestion from @millse , I have added a “last Message Received” variable, which you can use to create a trigger to do what you’re asking. Hopefully it works for you - let me know! Here’s a video of how to use it. You’ll need the latest build (1.1.5 or later). [[MIDI Trigger Demo] ](https://www.youtube.com/watch?v=Wgjdy9xk7AY)

Yeah, there’s no “standard” for channel numbers, but in reality they’re numbered from 0 - 15, but most people familiar with MIDI expect to see them as 1-16. The log is showing the raw value, while the action is showing the “converted” (1-16) value. I probably should make them the same to avoid confusion!

This method works.
Just one note.
It only works if I turn on the “FULL LEVEL” mode on the controller and it sends commands with Velocity = 127. Otherwise, I don’t know how to make it react to Velocity having a different value each time I press it.

Great!
To do what you want, try this:
1. Go into the trigger and remove or disable the Condition `internal: Variable: Check value`.
2. Add a new condition `internal: Variable: Check boolean expression`
3. Set the expression to look for just the first part of the incoming message. For example, to trigger on any noteon message on channel 1, note 0, use this expression: `includes($(generic-midi:lastMessage), 'noteon_1_0')`
This will trigger the action on any velocity **above 0** for note 0 on channel 1.
My instance of the `generic-midi` module is called `generic-midi`. If yours is named something else, then substitute that name for the part before the `:lastMessage` in the expression. e.g. if you have named the instance you’re using of the generic-midi module `my-midi` then the expression would be:
`includes($(my-midi:lastMessage), 'noteon_1_0')`
Let me know how that works for you.
