Waldorf Iridium w/ MPC 3.9 MPC Live 3 - sustain pedal issue

Hi. I have a Waldorf Iridium Keyboard and an MPC Live 3. I’ve tried this with both DIN and USB MIDI and get the same result. I’m running 3.9 OS on the MPC Live 3, and 3.3.0 on the Iridium. If play a note on the Iridium and then press the Sustain Pedal, and then repeat that exact note (or ANY sustained note), it does not trigger the second note on the MPC. For example if I play C C C C, the first C sounds, but the other three do not. If I record the input, I get one note, but no more (so the MPC becomes unviable for capturing MIDI streams too). The retriggered notes DO sound on the Iridium or on the Astrolab or Kyra that are on a DIN MIDI connection to the Iridium (So I'd get four C's on those). It’s only the MPC that has this problem. Has anyone else run into sustain pedal use issues with the MPC Live 3? Is this a known issue that I just ran across? Does anyone know if this happens with something like an Osmose Expressive E as well? I could abandon the Iridium if I had to (or move to an Iridium module), but the keybed is super nice on the Iridium. I've spent a few hours searching forums and trying different routings (MIDI DIN/USB) but am a wit's end. Any help is greatly appreciated.
