Yeah, well... To be honest I am a bit disappointed in SD. I recently bought a MixPre-6 and it arrived with a dead RTC battery. No big issue (besides the fact that it can't keep time), but I had to send the new unit in to SD after a week. The firmware doesn't seem to be the most stable, either. How they could miss this file splitting bug is just outside of my imagination - and I work in software engineering. Also, I find the different modes (basic, advanced, custom) to be extremely confusing. It just does not feel intuitive to set Gain to 'Advanced' vs. 'Basic'. Every time I come across one of these settings I have to google what it actually does. Having a setting to set the "Channel Knob" to "ISO Gain" would have been way more intuitive. I actually think the Zoom F8 is more intuitive than the MixPre. Currently, the only improvement the MixPre has over the F8 for me is its size, the possibility to power it from cheap USB batteries and the (hopefully) better preamps.
