Yamaha DX100

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.

I own it for 3 years and unfortunately didn`t dig deep into it. But after reading the comments above I change my mind to sell it. Easy to sell but hard to find one. My DX100 comes with original case, manual, adaptor. Just have to press few times some of rubber buttons - f##ng dust I suppose.

One on the best bass-synths. For some reason it just sounds better than the rest of the DX/TX line for bass sounds.

I freakin' love this synth. This was my first FM and digital synthesizer, and I will never go back to anything else. It has two plus's. It is a keytar, and it is small. If you really work on your sounds, it can compete with big expensive synthesizers. I just dueled my friend who has a Roland V-Synth, and He was blown away by the sounds it produces. It is really easy to program too. Definately worth hunting down, but not just for Roger Troutman patches.

I owned one of these about 2 and a half years ago, for a few months. I got it for a really low price, as one of the keys was shattered. When I first plugged it in, I found almost *all* the keys weren't working, so I opened her up. I modified the rubber contact strip which ran the entire length of the keyboard, by threading a string all the way through the middle of it. This worked, all keys except the shattered one, were then working!.

I loved this little machine so much, easy to program, punchy lil sounds, just wish I had some effects units at the time, cause it really could use some!. I sold this unit, and grabbed a TX81z instead. I have to say, the TX81z was much cleaner sounding, but the DX100 has a gritty character that is simply adorable!

Most strapon keyboards look like you're trying to steal a piano. The small size looks "better" on stage. The ability to reverse the wheels' direction and use a wireless (BORROWED from my guitar player) made this a great solo axe. Put it in mono mode and "borrow" his FX pedals too.
