Thanks everyone for your nice comments and thanks for not starting the usual Korg vs Yamaha fight ...
Babette - I would not recommend owning both unless you have a studio and need the extra sounds or unless you have extra $3000.
In my opinion, when you gig and play real time (I'm not talking about midi songs) you need to be able to activate and control many of your buttons - song variations, fills, sound selection changes, pads, vocal harmony you may want to control during etc.
The instruments are very different on their ergonomic layout.
I think that switching between the 2 for alternate gigs will be very confusing for your "muscle memory" and your hand will reach out to the wrong button or location.
This leads me to the next section of Ergonomic Design - (Layout of the keyboard).
I got to be honest - although it seems like Genos allows more functionality... The Korg has better ergonomic design (for me)
The pads are on the left and close to the transport. (start, stop, fills, variation)
These pads are often used to activate loops and be in essence another variation to the song section.
Your left hand should be naturally reaching left for either set a fill, new variation or a .... pad.
(This was the T5 design and was by far better for me).
Another key button not hidden under menus (or registration) is
chord scan.
The Korg has 2 buttons close to your right hand which will allow you to scan lower, upper or both parts of the keyboard.
This is excellent when you want to switch between playing your full keyboard to recognize chords (which I do 90% of the time) or go the solo part of the song. With this you can immediately switch, play the chords on the left hand and the solo you play with your right hand will not interrupt the chord recognition.
Moreover - it seems like the Korg had something I wished Genos had for many months.
Its seems like you can save the chrod scan configuration with a sound.
So when you select a sax it will deactivate the full scan automatically and will just go to lower scan.
A piano, e-piano sound switch will keep you on full keys scan.
No matter how you look at this this is available in a button with a led indicator close to you. - Very useful for me!
Metronome - The Korg has a button to lock the tempo.
"Temo + -" On the right hand, allowing the keep changing the chords while changing tempo.
Fade In/Out - the Korg has these dedicated buttons right by the transport.
Sound and Style Criteria buttons - instead of touching the screen constantly the Korg has buttons for each criteria.
This can all be done with Genos - but it feels more natural with Pa4X.Screen Tilt - The Korg screen can be tilted and if you ever lost your screen in the Sun using Genos - this is very useful.
I think that the material for the screen is different too.
The Korg Screen feels like an Ipad screen while the Genos is soft .... and few cases I have to re-touch it.
Last -
Tempo Reset -I know that many of you will not care about this ...
I have seen many people who are willing to take take a song with changing time stamp (4/4 -> 2/4 -> 4/4) and keep using a 4/4 style throughout the song without feeling it. (In this case your 3 beat becomes a "1")
I can't ...
It confuses me and the style feeling is wrong.
The fills are not going sound good and they will be coming half way ...
The Korg has a reset Temp button.
While you are playing a style, no matter where you are in the bar, hitting the button will reset it the style to the "1"
this is critical for many modern songs and the fact that you need to go through so much trouble with registrations is killing theses songs for me. (Just avoiding them with Genos or Midi file with DAW edit).
True - Genos does have "half a break" optional pedal function.
I tried it for a while - 1. This only works on symeric tempos (so songs like 4/4 -> 3/4 -> 4/4 cannot be handled)
2. It takes a lot of training to activate the pedal on time tohhave the half bar triggered.
Having said that, Vali informed us that temp reset is coming with Genos 1.4 update.
If nothing else comes and only this feature ... I will be extremely happy.
I know this long and it feels like I'm recommending the Korg ....
However -
I need to say that with Korg I feel that sometimes the chord recognition is not accurate, there are hickups on chords changes and I'm not sure Korgs recognize the "Jazzy" chords so well - 7,9,11,13. I sometimes struggle to hear the Korg play them back in the style accurately.
Bottom line -My main keys are Genos and at this point it will remain my main :-)
