I have just checked the Data List (quickly from my mobile phone). It seems to me that the sound generator is the usual Yamaha XG (we all know from 3 decades), with features more or less aligned with late PSR S arrangers. The DSPs are those of the newer PSR SX 700 (5 inserts).

This means that it *should* be perfectly compatible with our software (www.groovyband.live), possibly with only very minor sound substitutions.

In practice you could transform your DGX into a full featured arranger workstation (way more advanced than your Genos) with 906 styles built-in.

The demo is free, and should work both on your Genos and DGX 670.

If you would like to try, it would be an interesting comparison: 4k€ vs 800€!

Let us know!!
