So going by my 2nd week with the E-A7 using as an inspirational tool.
My goal is to build music from the ground up to be exported to the DAW via USB.

Most included styles are not really for me maybe except a few to get some groove going.
Since there is no sequencer, the style creation and pads are my new best friend.

I was having doubts over the past couple of days of the ability to pull it off.
I now have figured it out and it's quite a good performance/backing instrument, one of the best I have tried recently.

Creating drums elements in a blank style is quite easy to do I really like this part.
Drum kits are really nice especially is you are careful with velocity.

However the accompaniment and pads with the chord detection were driving me nuts.
I usually like to turn it off chord detection so it behaves like a pattern sequencer but this not possible on E-A7.

So switching the chord detection to "pianist" and making sure I am not hitting "chords" on the left side, it behaves like a fixed backing part. I believe you can go up to 2 notes simultaneously without having your stuff transposed (if you make a mistake do a C major it will revert back).

This means when the left side is used solely for bass purposes OR monophonic sounds, then the chord recognition does not take effect. Great!
You are free to use pads for sequences without having it transposed. This was my main gripe and I think I have it covered.

Going back to the sounds, they are all quite nice and especially true of the acoustic sounds.
The synths are good too but adjusting the ADR envelopes in the mixer is a bit tricky (as usual for any arranger) and not as flexible as a real synth but acceptable.

Not convinced about the reverbs, I still need to experiment. I think they are high quality but getting it right is tricky (I tend to use it less and less anyways nowadays).

I tried the tone editor. Pretty nifty tool it can access layers, LFO's, envelopes and filters modes where you cannot using the hardware.
It is really almost like the new Roland editors with partials. My only disappointment is there is no "keyboard tracking" available as modulation source. Again, typical of most arrangers and no biggie.

I believe I will hold on to it as it is flexible, good sounding and a productive enought that I can justify it.
I really wish they would add a soft switch to turn off the internal speakers. Having an dummy plug in the headphones is really weird..
