MQ MIDI Controller Window (Sound Checker)




The MIDI Controller Window window is a utility window which plays no part in the actual editing or storage of SysEx. It is used to generate standard MIDI messages: Notes, Poly Pressure, Control Changes, Program Changes, After Touch, and Pitch Wheel Changes. Should the need arise, this window provides you with a complete range of MIDI control and auditioning capabilities.

For example, if a drum sound assigned to a particular note (in an instrument with drum capabilities) is being edited, click on that note to audition it

This window can be used in conjunction with the Standard MIDI File Sequence player. You can have a sequence playing and easily experiment with adding controller information to the sequence from the comfort of the computer.

The MIDI Controller Window automatically tracks and retains the MIDI channel and Port used by the last active Patch, Bank, Collection, Set, and Library Window so that auditioning Patches using the correct MIDI Port and channel is easy.

Using the MIDI Controller Window

To open the MIDI Controller Window, choose the 'Midi Controller' button or Utilities/MIDI Controller Window. When the Studio Window is active.

The MIDI Controller Window contains a graphic keyboard. Clicking the mouse on any of the notes will play that note on the selected MIDI channel and Port. If the mouse button is held down, dragging across the keyboard will play the different notes.

The window also contains sliders and a numeric display for each MIDI channel. These controls are used to generate a complete range of MIDI messages. In the upper right are the following selections:

MIDI Port: selects the MIDI port that the MIDI events are sent to.

MIDI Channel: selects the channel for the keyboard created MIDI messages.

Vel: sets the velocity level for notes that are played on the keyboard


For each of the 16 columns there are six parameters. There parameters control the following functions:

Patch #: click to display a pop-up menu and select a patch number to send on the MIDI channel

After Touch: uses the slider to continuously transmit after touch events. This slider will automatically snap back to 0 when released, just like a real keyboard.

Pitch Wheel: uses the slider to continuously transmit pitch wheel events. On Windows, this slider will automatically snap back to 0 when released, just like a real keyboard.

Poly Key Pressure: transmit pressure levels for the last key played on the keyboard. On Windows, this slider will automatically snap back to 0 when released, just like a real keyboard.

Pan: send a pan position message (controller 10) to select the stereo output position for the channel

Control Change: uses the drop-down menu to select a controller number (ie. Volume = 7, Breath Controller = 2), and any of the 16 vertical sliders will output messages for that control. The default selection is Volume.


The arrows (<<, >>) are used to select the octave range of the graphic keyboard.
