Anyone know how i can find a gen patcher that i may be missing?

in the gen~ helpfile, under the mc tab, the comment to the right of the [mc.gen~] object says: look inside for example of new mc_channel and mc_channelcount operators

When i open [mc.gen~] by double clicking, I only see the default in1+in2=out1 patch. I would love to see those examples of the mc_channel/count operators :)
