Hi Hans
I'm in a similar place, but debating between the Fantom 0 and the Yamaha MODX.
Have you had a chance to listen to the Fantom 0? The interface really interests me, but I can't quite tell how good the sounds are; I've read many reviewers that feel the Yamaha sounds better.
Hello Luis, I have tried the fantom 6, not the 06, which is the light version.
Although apparently there are similarities between both models, undoubtedly the Fantom 6 (flagship) has more controls.
Now, I personally feel that MDOX is much better in terms of orchestral sounds, plus it has one big advantage over the Fantom 0, and that is the super knob, which allows you to change multiple parameters at once.
I like the demos of MDOX, by Dom Sigalas, he gets a lot out of this great machine.
Another thing I like about the MODX is the smooth sound transitions.
You can go from a piano solo to a full Orchestra in milliseconds by using a foot pedal to control the Super Knob (freeing up your hands) or directly from the Super Knob.
Roland is excellent when it comes to synth sounds, and they have a very good tool which is the TR sequencer, and the Piano Roll.
At the end of the day, what really matters is what you are most passionate about in a keyboard.
I think that each brand has its pluses and minuses, and they are designed to complement each other.
just my opinion
Cheers
Hans
