SOUNDS

These sounds are more than adequate. This is very surprising for a small module that age.
The output level is very good (better than the Roland JV / XV)
It gives off a good momentum and good precision
The sounds of acoustic and electric pianos and organs, bass, drums, string ensemble are very good.

OVERALL OPINION

I've had at least 14 years, but I use it more because I have other expendeurs and synth now.
But every time I replay, I find it really pretty.
There is more variety in a register / pop / rock qu'électro because the sound editing is weak and has little current synth sound
This is a module to GM if we have no other that will make many services as well as computer music in to play, the sounds are much better than some entry-level keyboards (PSR and other casio )
