It is not neccessary, and is in fact rather rude, to post the same question in multiple places (including threads like mine where it's off-topic). Once is enough. You also might try searching, because this has been talked about before (obviously not too long ago, given the newness of the 57).

Anyway: the functionality you're talking about (SL1 "emulation mode" on a TTM57SL) is reportedly in the works for a future version, but is not possible at the moment. Hopefully soon.

so one could use the fx sends as pass thrus? and it is not necessary to won both units; DjMark? yes, it is rude to post multiples.

ok. reportedly in the works for future versions... sigh :(

Wait why can't you use the fxs sedn on one channel and the master for the other?

The FlexFX is post fader, so you would get one channel from the FlexFX sends, and both channels through the master.

Here is a way to use the 57 as an SL 1 now scratchlive.net

Isn't it post line fader but pre crossfader.

No, the faders are summed, post fader is post both faders.

Suggestions for this feature are be posted here.
