Thanks for your response. I do understand your position as a manufacturer, and I was explicitly referring to the ET312 firmware, not to Estim Systems products or code. I would also like to mention that I am not among those who call boxes 'crap/shit/rubbish'. I used to own a 2B and I thought its built-in routines were quite good. I do not complain, I just try to explain what innovations are possible and what their benefits are, and I can definitely back that up with the devices I conceive, design, build, use and sell - something I've been doing for over three decades.
I think dismissing something that you have never experienced, with the argument that "we've been doing it this way for 20 years", is not particularly conducive to a fruitful discussion. Has it occurred to you that people cannot ask for things they cannot imagine, like patterns that are perceived as moving across the skin and through the body? Yes, TENS-like pulses and channels work. So did the Ford model T.
As for fine-grained control over the pulse sequences: that is exactly the thing that allows people to create routines that work best for them personally. And while I'm sure a majority of stimmers do not care for it, quite a few do - as exemplified by the sheer number of custom stereostim files that are created all the time. The easier we make it for non-programmers to write routines, the more people will do it.
Anyway, just in case it isn't obvious
I actually do think Estim Systems are doing a great job, as one of the very few who keep improving and updating their products. So, hats off to you.Mark
However every request or comment does get filed in my internal list of 'I wonder if I could do that',,, that is the fun of being a designer, so I will never say never on anything.
