Question about the Sequencer & Audio Tracks

I see Roland says that the Fantom G sequencer can hold up to 24 channels of audio. What I can't seem to find information on either online or in the manual is if these are 24 tracks of mono audio or stereo audio. Like if I record something in stereo, does that eat up 2 audio channels like you'd have in a traditional mixer or does it only take up 1 audio channel? Thanks! :D
