It's that bad the DX9?


Well, I’m just interested in the Yamaha DX9 because is the only cheap synth I found, and because is from the DX family.
However, I’ve seen in forums and they say the DX9 is the worst in the DX family.
I just want it for bass lines, talkboxing (I have the c is c patch parameters) and all that, I just need to edit the patches, but…is that true the DX9 you can’t name and save your edited patches?
150 dlls It’s a good price for one of those?
Thank you
