Hi Oej, welcome to the forum... I suppose the 1212M has the same control panel as my 1616M, the EMU Patchmix. In there you can see the ASIO 31/32 strip, you can add an insert 'SEND to Physical Output', select the output that you want there... If you want more output channels, you can add more Patchmix strips with other ASIO channels... and route them out the other outputs. You can also change the in- and output names in the Patchmix panel (below...), then those names show up in the ASIO hosts (Reaper...). You can see I haven't named my outputs, but my inputs have usable names (Dock A/B, J99, ...) Eddy
