I really need KORG PA 500 owners to chime in on this one......My Budget is a touch over $1000......enough for the PA 500
One of SZ's members, FransN has a PA-500...he may be able to enlighten you on it's sequencer capabilities.
From what I understand, the PA-500 has basically the same sequencer as the more expensive models.
I wonder if the microArranger has the same caliber of sequencer?
Rikki's suggestion of Band-In-A-Box is also a good one.
