HI Mike

You seem to have mentioned workstations and synthesizers a number of times, therefore I suspect this is the type of sounds you use on your arranger, and why you are getting the problem, as arrangers are not designed for that intense continuous sound, (The normal note stealing algorithms just don’t work) which is another reason why arrangers are not used in full professional production of music and film. (There only suitable for the first scratchpad)

The only arranger keyboard that has theoretically unlimited polyphony is the Wersi Pegasus Wing where the polyphony is linked to the on-board CPU & Ram, (Which can be upgraded) and which in its current format even if you had everything going (Including the on-board VST) you would still not be anywhere near its polyphony limit.
