Yes I do and glad you asked! I still have my Roland RS-70 that has 64 note poly. Note drops aren't a big issue with the RS-70 because the RS-70 (like the Korg TR) for example have 2 element voice engines. A two element voice engine with 64 note poly is good. Now there are those "few" voices on the RS-70 that "are not" designed for use in a mix (the manual even states this) because the poly count per note is quite large. Some of the RS's voices can use I think up to 8 notes. Those sound are for live use.

Now 64 voices with a 4 element structure that is what's found on the MO-8 is just bad: Once you start to sequence, then add the arps, and use of sustain pedal into that mix and BOOM! Poly is GONE WITH THE WIND my friend.

Now Roland has one GREAT feature that I have been after Yammie about for years. Roland has a feature called "Voice Reserve". In a mix you can manually set the poly limit of each track/part to avoid note drops.
