First of all i really really thank you ofr your reaply, thats a brand new manual for me and i will try things, but my knowledge on midi is very limited , so i doubt i will make things right
Trying to make my self clear on what i am trying to do (and forgive my poor english) :
DGX is great electric piano, with great keys and very good appereance. So i bought it during the quarantine, without having the change to try it first in a physical store. I was thinking that i will combine the advantages of a PSR with an electirc piano. After trying it for some days, i realised that things i was able to do in my old (very old) PSR, i am not able to do with DGX and it was kinda frustrating. I dont need many things to do , neither i am a great musician, but i thought things would be easier.
First thing i realised, is that i cannot rename the registrations, so i have to remember (or note down) what rythm and sound i have in every registration, because you choose them only with numbers! The reason that i pick registrations, is that i can change the main voice even from tablet (the only thing i finally made from tablet), in the voice 000 as you said. But i want to change rythms also and even more inportnat, i want to change transpose! And DGX has the transpose function, in a function key with dosens of other choises, so it is impossible to change it fast (you have to go through a menu with many many other functions). That was another frustration, so i realised that the only way to go fast from one song to other, is that registrations, that keep rythm (style), voice AND transpose. But after many many tries, i never made it to change them via table or pc easy, i have to deal with the registration numbers.
But actually this is not the only thing that bothered me on DGX. I foudn out that there is only 1 (!) auto fill in button, so if you play a style in the A section (i hope i say it right) and you want to fill in but NOT go to B section, you just cant to it. Same goes from B to A. My old PSR had more buttons to fill in, it was up to you while playing , if you will just fill in or fill in and change section (A to B, B to A etc). I found a silly way to deal with it (pressing fill in 2 times very fast, makes the fill in (drums) but stays in the same rythm section, but you have to do this really synchrozied, otherwise the result is really funny. (i hope u understand what i am talking about, i really dont know those terms in english). So i thought ok, this is not easy to do while playing, maybe i can use the food pedal to fill in. Nope, u can set up the pedal to do many things, but not that.
Other silly things i found out was for example the 'always on' function about the internal speakers. I have connected external speakers and i want to hear the internal speakers at the same time. It works, u press 'fucntion', u go through dosens of choises and finally you find it and set it to 'always on'. But when you turn keyboard off, that goes back to default and this u cant save anywhere. So sometimes its easier for me to discconnetct the external speakers (if i want to play in low volume), than searching all the functions that they are in one and only button.
More things? I can not mute one channel of a style! if i dont like something in a style, i cant do anything. My old psr had 'mute' key for every channel on styles, DGX doesnt! Thanx god i use some software do edit styles on pc , before i put them on DGX.
So, with this and that, DGX is great piano, i really like the feeling on keys and the sound, but if you want to deal with styles etc, i think is not a good choice. Even if i make it to do some things with midi cc, i think the keyboard should have 2-3 more keys to make things easier and maybe some better firmware to do basics (renaming registrations for example). Ofc its my fault and not Yamaha's fault, they promote it as an electic piano, i foold my self a bit that with 750 € it would do everything
Thank you soooo mcuh for advices, i will try them and let you know if i made it to do something, if not i will get use to it
