The Ki Pro does support 4 channels of audio within an 8 channel file.
Ki Pro v3.1 manual, pg. 58:
2.3 AUDIO CHANNELS
This parameter selects the use of either two or eight audio channels via SDI embedded audio. Generally, when working with camera sources, there are only one or two audio tracks being produced, and therefore 2 channel would be the appropriate selection. In post production use, there are often more channels of audio required, so 8 channel audio may be the appropriate choice in such situations. Ki Pro only allows for the selection of either 2 channels or 8 channels of audio to be written to the QuickTime file that is recorded. Therefore, if the source has more than 2 channels of audio, but less than 8 channels of audio that need to be preserved, the CONFIG Menu parameter 2.3 Audio Channels would need to be set to "8 Channels."

Yes I understand that and we run all our 4 channel files thru an episode job that adds another 4 just so we can play them back on a KiPro. We would prefer not to do that. Please add 4 channel playback where the file only has 4 channels.
