Yamaha DX100

Yamaha DX100 Image

The DX100 is a small and portable budget DX synthesizer from Yamaha. Like all DX's it uses (FM) Frequency Modulation synthesis. It's not the easiest form of synthesis to program but can result in some excellent sounds. The DX100 is not as flexible nor powerful as a DX7, but it does have some cool sounds. It is most renowned for its great analog bass sound (Patch #01) that is awesome for techno, house, jungle, and acid music styles; it's very gritty, the bass tone with gristle! However, any other preset sounds that you'll find in the DX100 are pretty bad and require editing for anything else useable.

The DX100 has mini-keys and only 49 of them. No filters, arpeggiators, effects or programmable controllers are available either. Small pitch and mod wheels in the upper left and guitar strap pegs make this synth usable for live use if you're feeling whimsical. If you mess around with the settings on Parameter 13, even if you don't know anything about FM, you can get some seriously twisted sounds out of it. If you're willing to spend a little time with it, it has a lot more potential than just that one bass sound that people will eventually get sick of. And at its currently low street price, it just might be worth getting. It is used by Orbital, Scanner, Jean-Michel Jarre, Autechre, Laurent Garnier, and countless other house and dance artists.

Bet Bill feels like a fool. :X

I'll check out your group, Patti!

The "obsession" with little keys is that it allows you a playable number of keys while maintaining transportability. I find the inconvenience of learning to adapt to little keys much less drastic than only having 25 keys to play on. 2-octave MIDI controllers seem more conducive to DJs than keyboard players. You can actually use two hands at once on a 49-note 'board, even if they're tiny.

I can't wait to get a hold of a DX-100 - I think it'll look awesome with my DX-11! Maybe I'll top it off one day with a DX-1. :D

No offense to Bill, but I am not a little person. I have a physical disability, use a wheelchair, and have limited use of my arms and hands. I have been blessed with musical talent and use mini keys to play in a band called OLYPSYS (check us out on reverbnation.com/olypsys) We just finished a gig at the Hard Rock Cafe Boston. You never know how modern technology can help people with limitations until you personally experience it.

this board was used by the late roger troutman along with the electro harmonix golden throat on his endless list of hits.....as a solo artist or with his group zapp....sampled by an endless list of rap hip hip artist over the last two decades....that's the only real reason these pieces of crap are sought after....i prefer the dx-21...same board with normal keys....
