I am trying to use the Kronos Midi'ed to a Yamaha P95 to set up a simple Midi, I switch to a combi or program on the Kronos, and the P95 drives it. I notice if I play fast or with heavy sustain, I get cut outs on the P95, but not if I play the same thing on the Kronos alone. See the video below to hear what I mean (I played a pile of mush on both the Kronos and the P95 - only P95 shown in video). You can skip to the 30 second mark of the video to hear the cuts.

The combi being used has around 5 programs playing at the same time, and does require the Kronos to use the voice stealing algorithm. However, after a bit of play I have noticed this same cutout phenomena on the Kronos midi'ed to a keyboard using just the basic Kronos Grand, which never has to use the voice stealing. Is there something I am doing wrong, or is this just the nature/limitation of midi?

I can only guess here. According to specs I've looked up on the web, the P95 only has 64 notes of polyphony -- I have no idea if the P95 has any kind of dynamic voice allocation. Nevertheless, you are likely exceeding the P95's polyphony limit when you are holding down the sustain pedal. Try lifting the sustain pedal now and then.

I suppose it's also possible that the Kronos is sending too many MIDI messages (note ons, note offs, sustain, other CCs) for the P95 to cope with... maybe. Dunno.

Is you MIDI connection The P95 O/P to the Kronos I/P ONLY- or are you running a Kronos O/P back in to the P95 MIDI I/P. That might cause a loop. Not sure. If you have that configuration try disconnecting the Kronos O/P from the P95 I/P.

I've had problems in the past with cutouts when using other manufacturer's controllers with Korg gear.

In those cases, the problem was down to the Active Sensing messages. They send a steady stream of traffic down the MIDI port so the synth knows when they have been disconnected and then that triggers an all-notes-off or panic event to prevent hanging notes.

With controllers that do not send these messages, notes often get cut off periodically on the receiving Korg synth. I'm not sure why.

Not sure if this could be your problem. I was unable to watch the video right now.

I would also make sure to verify if the controller is sending on more than one MIDI channel at a time. They can send multiple channels of duplicate MIDI in certain conditions. That could easily cause polyphony problems.

I'm not sure what exactly is happening there but if I was to guess I would say that since you are using the P95 as you controller keyboard and your Kronos as your slave, you might just be overloading a memory buffer in your Kronos. If there is such a thing. When you pause for a second or 2 does the problem go away for about the same amount of time?

Ok so it's time to check more seriously if Kronos is getting overloaded or if the MIDI messages are arriving incorrectly. For each test, you'll do the following:
1. Kronos is getting overloaded. For checking this, you go to the Perf tab where you can see the CPU usage for voices (as well as voice stealing) and also the CPU for effects usage. Check if you're getting heavy CPU usage (sustained 100%) for voices or effects. Compare usage levels when playing directly on Kronos and when playing with the controller.
2. MIDI messages are arriving incorrectly. Go to Seq mode and record your playing directly on the Kronos, then you record the same performance from the controller and you compare the results.

After you finish the tests and get results, report back and we'll try to guess the next step

I have also problems with Cut-Offs when connecting my Korg SP-250 to the Kronos. But only, when I connect it directly, as soon as I use Midi out of the SP250 to a DAW or VST-Host and from there to the Kronos, I don't have these problems anymore...
