Rev-X vs Yamaha spx-90

Just curious, is Rev-X is the same as Spx-90?

no

where u seeing this in cubase?

I guess it’s from an interface with DSP

But, in SPX-2000 have same Rev-X algo

but it’s not an SPX-90
Rev-X is only one possible variant of reverb algorythms in the SPX-2000 and some later introduced devices

the SPX-90 is mid 80’s so far away from Rev-X
Rev-X was introduced 2003 with the SPX-2000

Rev-x is great, I personally find the room algo. good for snares.

Thanks for the clarification!
