mm6 keys feel like the PSR series.
i tink the triton le is only sligghtly better.
if u tink triton le is sucky, try yamaha so3 and roland rs 50/90
.
i tink the mm6 keybed is almost the same as x50, roland juno g. have tired al in shops and studios...i think the x 50 sounds the best.
juno G is, amazingly, a bit bit disappointing. u have to try all 3 light weight synths to noe. was actively looking for a good and light workstation.
maybe its just my personal preference.
