ColorSource Spot

Sorry if this is the wrong place to ask this, I wasn't sure where else to go. Our church recently purchased 10 ColorSource Spot RGB lights. I am failing to understand the difference between 5-channel and Direct. In 5-channel mode, does the fixture handle the lime mixing or is lime left out altogether? When we run direct, and leave lime off, the resulting light is not cool white as I would expect from a full RGB mix. Instead, it is very magenta/pink. When mixing for a warm white on 5-channel, it is difficult to achieve a nice 3200K warm white from the console. We couldn't afford an ETC console so we're using something (M-PC and M-touch) that doesn't have the correct profile. Instead, we're using the built-in profile for ColorSource Linear. Any help would be great. Thanks!
