There is something I don't understand Ian. How can the Tyros 4 have Motif XF patches while they use different sound engines. The motif has AWM2 and the Tyros AWM.
Actually Frans, I should have described them as "Motif XF-like" patches.
The patches sound very much the same to my ears.
They use
slightly different sound engines, but
both are based on 16-bit AWM...
earlier AWM (before 1992) was 12-bit.
Some AWM are 32 note poly, some are 128...some AWM2 are 32-note poly, and some are 128. Both have been improved over time.
I honestly am not sure of the differences between AWM and AWM2...can you tell me what they are? Perhaps someone else knows?
Your best bet is to compare Tyros4 and Motif XF yourself...I'd be interested in your opinion.
Ian
PS...there are also some excellent Motif XF-like patches on the PSR-S910, but the Tyros4's are beefier and have more depth and punch.
