Everywhere I look in the multiplicity of manuals, it states that the arpeggiator function must be mapped to a MIDI instrument. Why then are there places in the software instrument listings, ES1, EXS24 and others, that have "ARP" as behind their preset name if it's not intended to be in arpeggiation? Or is trying to refer to the classic ARP synthesizer? Which is related to the question of how to arpeggiate a software instrument (?), if possible. Inquiring minds want to know. John Lee
