Hi Gios,
all important information about Yamaha keyboards are listed on the respective product page, for the SX700 here:
>>>
https://uk.yamaha.com/en/products/musical_instruments/keyboards/arranger_workstations/psr-sx700/index.htmlYou will also find all manuals and other downloads there, for the SX700 here:
>>>
https://uk.yamaha.com/en/products/musical_instruments/keyboards/arranger_workstations/psr-sx700/downloads.html#product-tabsIf you haven't already done so, please download at least the following three manuals as PDF versions: Owner's Manual, Reference Manual, Data List. (It's best to download ALL manuals at once.
)
Alternatively, you can use the Yamaha Support pages:

https://uk.yamaha.com/en/support/updates/index.html?c=keyboards&k=psr-sx700Documents & Data:
https://uk.yamaha.com/en/support/docs_data/index.html?l=en&c=keyboards&k=psr-sx700The three manuals mentioned above should actually be downloaded BEFORE you plan to buy a keyboard. It is best to also download the manuals for the corresponding
larger models (in this case
SX900 and
Genos). So you can compare the technical data, functional differences, etc. BEFORE buying.
By the way: I too often come up against
technical limits with my Yamaha keyboards (Tyros5 and Genos). But we have to live with that ...
Just one example: In 2014, when the Genos was still in the development phase, Yamaha Europe invited some "power users" (including myself) to some meetings with the Japanese Genos development team. Of our suggestions at the time, what could be improved on the Genos compared to the Tyros5, a maximum of 10% have been implemented to date. (The Genos came out in 2017, and we are now at firmware version 2.02, with new functions being added and improvements made.)
P.S.
I recommend that you take a look at the Yamaha
Synthesizers, e.g.
Montage,
MODX and
MOXF:

https://uk.yamaha.com/en/products/music_production/synthesizers/moxf/index.htmlThese Synths have a lot more control over sound editing, controller routing etc. than arranger keyboard models like PSR-SX or Genos. Maybe it's THAT what you're actually looking for ...
P.P.S.
The two Japanese Yamaha development teams "Synth" and "Digital Workstations" (= arranger keyboards) are, by the way, completely
independent. And traditionally these two teams are very reluctant to let each other "look into each other's cards". The Yamaha synths therefore differ extremely from the arrangers in almost every detail. (Except maybe that the same tone generator chips are used.
)
Best regards,
Chris
