thanks for this discussion - i've realised i was also confusing firmware for the mixer with computer software.
actually i can share some of my exprerience of using this thing as i bought it a month ago,
since then i played and recorded pretty serious concerts using all available inserts and without using any computer whatsoever.
also made one live studio records. all these were with drums, guitars, keaboards, flute, vocals,
and in one situaltion even with large number of specific ethnic instuments.
the best thing about it is how easy to understand and use it. the speed of setting up the stage for the gig,
4 independant monitors lines, the ability to save all parameters for the repeting venues, full dynamic processing for each(!) channel -
all these make our life as a musician not only much easier, but also far more enjoyable
the quality of the signal is more than sufficient. we tried any types of external memory and it really works with all of them.
when recording, it produces one folder for each song recorded. in this folder, each recorded channel is represented as a clear wave file with no fx uplied
and also main mix wave file, which is actually the sound of the band including fx and dynamic processing. in our case, 16 mono wave files and one stereo wave.
another fiture is managing parameters by means of mobile devices.
we connect two iPads to the mixer. one of them is on stage with one of the member of the band who's running instruments levels in monitors.
and second iPad is running the sound from the side of audience. so we also do not need any multicore anymore.
several things to be aware of. since only one usb is represented, in order to plug both: the wifi adapters for iPad connection
(acually i would say wifi transmitter since you don't need to use any routers, and "the" because there are only few specified)
and external usb drive for recording, i bought usb hub with extra power supply. it does work!
second thing - i normally first make primary mixing inside the mixer as it can replay recorded stuff provided you save the stage setting.
i do it in order to rearrange mainmix file because in conditions of a live concert your priority is always live sound in audience
so mainmix stereo wave file is never what you really expect to get.
also important - the level of the mainmix wave file is directly dependant on the level of the main out knob, a small thing which costed us a lot of time
and then, if it is still necessary, i relocate files to a computer where i do final mixing and mastering.
overall, i can trully say, i am very happy with this thing.
today is trying to test it with a connection with computer, but already see that much easier to use it on its own since it is trully a self sufficient device.
