An obscure feature to me is very important..
Patch remain..a feature that allows you to change a sound and have the previous sound hold till you play the new sound..A lot of boards[without mentioning brands] cut the patch off[very annoying]..
The other obscure feature is the proper allocation of voices[polyphony]..
I found Roland to be my choice for these features..
