MIDI drum trigger

MIDI drum trigger refers to an electronic drum module without built-in sounds. The module is only used to convert signals from electronic drum pads into MIDI messages which are then used to trigger sounds on MIDI capable devices such as drum machines, samplers etc. Also known by the acronym 'TMI' (Trigger MIDI Interface).

Examples of MIDI drum triggers include:

• MegaDrum
• eDrum which gave an initial inspiration for the MegaDrum project
• Alesis Trigger IO

among others.

There exists a multitude of PC based drum sampler applications (usually running as VST instruments) which can be effectively used with a MIDI drum trigger module. Examples of commercial samplers:

• Addictive drums
• BFD
• EZDrummer
• SuperiorDrummer2
