Upgrading Poly Evoler (Rack) OS with Edirol PCR-M1

This was unexpected enough to warrant a mention: the PER hangs when it is sent any of the upgrade sysex'es (OS, DSP, Voice). It shows the "loading" message, but the countdown doesn't start.

The setup:

  • PER v2.0, upgrading to 2.1
  • Edirol PCR-M1 as a MIDI interface
  • 10.6 and 10.5 Macs, latest drivers for the respective OS'es
  • SysEx Librarian, PolyEvolver500 editor

So it appears the PCR-M1 is doing something of which Dave Smith does not approve. I would be curious to find out what.

For the meantime, UM-880 worked just fine.
