Yamaha is a well known manufacturer of various products. One of which is most notably respected, their musical instrument division. Yamaha has been a leader in innovation for drum synthesis and emulation for decades. A particular area of expertise that has been responsible for many historically significant recordings. As technology develops, it will be interesting to see what they will deliver next.
In the early 80's, Yamaha produced drum machine instruments with very limited capabilities. Simplified MIDI implementation, as well as very low bit sound qualities. Back then, one of the most usable features was the MIDI output triggered from the pads. While this was the start of something interesting, but was in no way a full substitute for a live drummer at that time.
Nowadays, Yamaha is one of the main suppliers for digital electronic drums worldwide. They have perfected integration for accurate musician response, while providing amazing sound quality and realistic feel. Now Yamaha has pinpoint accuracy when dealing with midi triggering of the drum pads. A real advantage to their design is the diversity of the included sample drum sounds. These will include all of the most popular drum kit styles, as well as realistic studio kits and experimental. If at some point you find the sounds need to be upgraded, you can integrate with another drum machine, computer, or sampler to broaden your sound pallet.
Yamaha electronic drums are available in various forms, to appeal to every musician's needs. You can find midi integrated drum modules with on board pad sets. Or you can find one that emulates the traditional drummer technique. Some even like to create their own personalized mix of different types of electronic drums. Attaching small pad modules to their drum rig can add tremendous sonic capabilities.
No matter what kind of Yamaha Electronic Drums you decide to go with, you will be able to rely on the to perform correctly and integrate easily into your travels. Even the full size kits can be broken down into a easy to carry package, then can be set up again in a matter of minutes.
