I have been working on a few new mixer designs and the boards for the first new ones arrived today, it is an 8 channel version, switchable between stereo or split stereo/mono. What that means is that there are 2 outputs, the one on the left outputs stereo L/R unless the switch is set to mono in which case it outputs the Left side on the tip only, the output on the right only outputs the Right side onto the tip regardless of whether the switch is set to mono or stereo. The idea behind it is to allow somewhat more flexible routing when using stereo devices for example the Volca sample, or if you wanted to split the clock from the PO's to route elsewhere, or maybe to send to an fx unit or what have you.
