System.MIDI.Launchpad.Apps.FXControl

Description

A very simple generic live FX control surface.

There are 8 CCs (the 8 columns of the grid), and 8 trigger buttons (the side buttons).

The trigger buttons can function either as an on/off switch or as gate (active only during pressed). This is selectable by pressing down the side button(s) and at the same time the up/down button. By default, the top four are switched, the bottom four gate.

Example usage:

 main = runPureApp defaultGlobalConfig $ fxControl defaultCfg
