Hi Eduardo,
Due to time constraints, I can only answer you now. The user "andres_fprado" has kindly replied to many points in my favor.
As has been mentioned several times, the SX700 has significantly
fewer Preset Voices (of the types S.Art !, Mega !, Cool! And Live!). And even with the Voices with the same name and Voice Number (MSB-LSB-PRG), it is possible that these Voices do not sound quite as good on the SX700 as on the SX900, because a more complex multisample may be used there.
The VCM (Virtual Circuit Modeling) effects that are missing in the SX700 have already been mentioned. If a Voice on the SX900 uses such a VCM effect, the same voice on the SX700 can only use a "Vintage" effect instead.
It is similar with the missing Effect blocks (DSPs) on the SX700. If these are used/required in Voices/Styles/MIDI files on the SX900, but are missing on the SX700, the Voices/Styles/MIDI files concerned will sound different (worse) on the SX700.
Basically, of course, it depends on WHICH Voices and Effects you are using when comparing the two models. If you use Voices and Effects that are 100 percent identical on both models, they will also
sound identical on both models (via external speakers or headphones). If Voices, Effect types or required Effect blocks are not available on the SX700, the SX700 will try to use
similar Voices/Effects. But the sound result is then no longer identical to the SX900.
Finally, a very important point is that the
SX700 only has
400MB of Expansion Wave Memory, but the
SX900 has
1GB. (For comparison: With the
Genos the size of the Expansion Wave Memory is
3GB, and even here you can by far not install all the Expansion Packs you would like to have at the same time.)
By the way: Please take a look at the attached picture as an example of the many missing Voices on the SX700. It shows the available
Piano & E.Piano Voices on the
SX900 compared to the SX700. As I said: If a Style/MIDI file uses Voice/Effects that are not available on the SX700, the sound will be "different" (usually worse). And if you make your own Registrations or recordings, you don't have the missing Voices available.
I hope my explanations will help you again!
Best regards,
Chris
