I’ve been toying with AutoHotkey and MIDI a bit lately and thought I would share my findings in case anyone else finds it interesting. I’ve cobbled together a very simple “library” file that can be used to: Return all available MIDI input as well as output ports Open and Close MIDI input and outp…

Hi there, I have some knobs on my mechanical keyboard. How can I use this script to use those knobs as MIDI controllers so that I can assign these knobs to control the gain of my tracks in Cubase (for example)? I tried running the script but kept getting different error messages (I don’t have any kn…

Hey thanks for this! I have been needing to bind some keys to midi in order to control some plugins for a while, and your example probably saved me a few hours of messing around with a different AHK midi class library. Yours worked like a charm. Cheers!

I’m glad you found it useful. Out of curiosity and perhaps as inspiration to others, would you mind sharing your use case?

I use the ADPTR Metric A/B Plugin, which has a switch for a/bing your mix against reference mixes. I wanted to be able to trigger the A/B switch using my keyboard, and not have to reach for an external midi device. So the autohotkey script allows me to send midi to cubase from a key binding (using l…

I have made some tweaks to the library that improves handling incoming SysEx messages as well as a more reliable way of closing MIDI In ports. Updated version: AHK MIDI.zip (3.0 KB)

Have you considered making a video tutorial that explains the usage of AHK with MIDI in greater detail? I would like to learn more about your methods, but as a beginner in this subject it seems a bit overwhelming.

Hi there! No, making tutorial videos is not something that appeals to me. Sorry. I suggest trying the sample script provided above to get an idea of what is possible. If you’re new to AHK there are plenty of resources available online to help you get started. The program itself also comes with an e…

Looks brilliant! I just wanting a simple way to send to generic remote for some stuff to test (still on Cubase atm)…is this AHKv2? EIDT: Just read again…v1 only :frowning:

I have Arturia Keylab MK2 midi keyboard. In the middle of the keyboard there is a “rotary knob” that you can turn. You turn it to browse between different presets (in Arturia collection plugins) and then you have to press the knob to select the preset. I’m wondering if it’s possible to use AHK to b…

[image] Aleque: if I turn the knob one click to the right I would like it to select the next preset without me pressing down the knob. Do you think it would be possible? No. In user mode the jog direction and push are handled internally by the firmware. Jog can be handled externally in DAW mo…
