To set manually, uncheck the 'Auto Detect,' hold the mouse pointer over the 'channel' box and move the mouse wheel to select the appropriate channel, and then do the same for the 'controller' box. You might also need to set this manually if you have two simultaneous outputs configured on the VMeter (ex: both position and pressure). If you have multiple controllers, you can also click the little keyboard button and manually select the device you want.

You should now simply be able to touch a VMeter and have it automatically detected.

Once LMMS has started, right click on any control, and select 'Connect to controller.'.

Mutliple VMeters will work, but the MIDI is routed to only one program. On Windows, only one program can talk to a VMeter at a time. No other program should be talking to it either.

On Windows, it's important that the VMeter be plugged in before starting LMMS.

The VMeter is a generic USB MIDI device, so it should work equally well on Linux. This tutorial was written using LMMS 0.4.15 on Windows 64bit. So the VMeter (or any other controller) can only be used for live adjustments as of this writing. At the time this tutorial was created (Jan, 2014), LMMS does not yet support recording or playback of automation data. This tutorial will show how to control knobs, faders and instrumenets with a VMeter. LMMS (Linux MultiMedia Studio) is a free music production program now available on Windows in addition to Linux.
