Check out the KARMA
Not too many people touting the Korg Karma but it does mostly what the Triton does and it has this really cool KARMA function thing. As I go along I experiment with it, I am learning various uses for it and, the thing is, it is not only a good workstation with good sounds but it is an inspirational tool as well. Now, I have heard the Motif. It surely is nice too! Nothing wrong with any of these instruments. Anyone of them will do more than you will likely ever be able to do. To exhaust the capabilities of either a Triton, Karma, Motif or any other advanced workstation keyboard is a major undertaking. Very, very few users ever get that deep into these instruments.
The Korg Karma and Triton keyboards have expansion cards. They come out with new ones from time to time so the sound are updated. The bottom line is - as I always say - WHAT ARE YOU GOING TO USE IT FOR. Let the type of music dictate which keyboard is best for you. For instance, when I record an R&B or Pop ballad, the sounds in the KARMA work wonderfully. BTW, Karma and Triton have the same "sound engine". They sound the same for the most part. Anyway, when I do more electronic style dance music, I find I like the Waldorf and
the Access Virus b. In the meantime, I have a sampler that works in any style and I am just getting more into this particlar device. I am excited about the possibilties of sampling. I am new to the genre. I spent many years out of the music field. When I left, the DX7 was still sort of happening. The last rig I had was a DX7, a Roland Super Jupiter, a Moog Source. Prior to that I played a Rhodes ( I had one of the originals with thei silver top), a C3, and Arp Odyssey and a Clavinet. And, here's a funny one, my first electronic keyboard was a Farfisa Fast 4 organ. The point is this, times change, styles change. But certain sounds have remained constant. Throughout the entire time, Piano, Organ, basic Analogue Moog type sounds, digital bell like sounds, smooth warm pads etc. In the end, the insturment did not make Mozart sound beautiful, Mozart made the instrument sound beautiful.
So much of this "what is the best" kayboard stuff is pure fodder. Empty boasting. Kind of like 'my bike is better than yours". Shit, really, is there any decent keyboard player than cannot make great tracks using a Triton, Karma or Motif. I doubt it. And, when was the last time you heard a piece of music, loved the song, or piece or whatever, but decided you would not listen to it anymore becuase you detected that possibly the keyboard player did not use what you now consider to be the "best" keyboard. As others have pointed out, this is a highly subjective area.
Anyway, good luck with your purchases. I hope as much care goes into making the music as goes into choosing the instrument. By the way, anyone with money can own what someone somewhere thinks is the best keyboard. It takes hard work to create great music (or even good musci for that matter). But the point is, it takes hard work and from the hard work, the best sounds will come becuase he music will be good and you will have worked the poper sound into the texture of your composition.
SOOOO...Get the keyboard you like and work hard on your music. Then, your music will be great and by extension, your keyboard as well.
