The electronic drum, powered by a Drum Sound Module (also known as the sound module), is the central control unit that stores the audio data (controlled by a series of buttons and knobs), and the relevant input/output connections. The drum’s trigger pads communicate with this module to produce sound. The trigger pads themselves house sensors and other electronic components to identify strikes and the intensity of the strike. This complex setup helps increase the subtlety of the expression, accurately replicating the sound of an acoustic drum set. The trigger pads in newer electronic drums (mainly the tom pads and snare pad) are made of mesh (multiple layers) to reproduce the play feel of an acoustic drum set authentically. The other components in the set are made with a mix of aluminium / steel for the frame and rubber pads.
Electronic drums are great if you need a quieter way to practice or need a more flexible soundscape. They offer the same level of playability and practice potential of acoustic drum kits, only quieter, and with more versatility thanks to sampling libraries available with many of the kits. Some even let you switch out different pads and samples, load your own, and much more. With electronic drums and pads, there is virtually no limit to what sounds you can produce - including MIDI connectivity for DAW control. Electronic drums are now available at lower price points, helping reduce the entry barriers even further. Owing to its affordability, electronic drums have become the go-to for beginners looking to learn and grow their drumming career.
