Using MIDI Command Studio with OBS on Windows

MIDI Command Studio can be used as a practical control layer around OBS workflows on Windows. You can map MIDI controls to OBS hotkeys, build presets for different streaming or recording tasks, and use faders, buttons, and MCU-style controllers to manage the parts of your setup that OBS relies on. The app can also play samples from a dedicated Audio Preset.

MIDI Command Studio does not lock the controller into OBS-only use. You can build a broader workflow where some controls are used for OBS-related actions, while others control Windows input, app volume, shortcuts, or macros for other apps running at the same time. Using preset switching can extend the controller even further if needed.

One of the most useful options is Windows input volume and mute control. If OBS is using a Windows microphone or other Windows input endpoint, MIDI Command Studio can control that input volume and mute before the signal reaches OBS. In practice, that means you can change or mute the level OBS receives for streaming or recording from your MIDI controller. This does not change hardware preamp gain, audio interface direct monitoring, or hardware monitor mixes. It is controlling the Windows input level that software receives.

This matters because it lets a MIDI controller behave more like a live streaming control surface. A fader can control the Windows input level feeding software, while a paired mute button can mute that same Windows input stream. For many OBS setups, that means controlling what your audience hears without needing to reach for the mouse. The limitation is that some ASIO, exclusive-mode, or vendor-specific audio paths can bypass Windows input controls, so this depends on how the source is routed.

Mackie/MCU-style controllers also make the workflow clearer because the app can send feedback to the hardware. Compatible LCD displays can show preset and target context, so the controller can tell you what the current fader or strip is being used for. If you name presets and descriptions clearly, this makes it much easier to work in OBS-related setups without guessing what the hardware is currently controlling.

On single-fader MCU controllers, MIDI Command Studio can use the built-in CH1 to CH8 channel switching as eight switchable control slots within one preset. That means one physical fader device can control up to eight channel-style targets, with separate fader, mute, solo, and record-style mappings per slot. As you switch channels, the fader position, LCD text, and LEDs can update to match. In an OBS workflow, that can make one compact controller behave more like a small bank of stream controls instead of just a single fixed fader. For example, you could map Mic 1, Mic 2, Firefox, and a media player, each with its own volume and mute control, then move between them instantly with the device's channel buttons.
