Yes yes and yes!
Machine for "complete" production - yes!
We are not talking about new Madonna album or something with 100 tracks and SSL channel strips, but experimental "groove" / "minimalistic" approach, something you can program, then perform live with it, experiment, go deep and discover new sounds.
Despite market is "saturated with grooveboxes / drum machines", there's very little really "pro" choices, with no compromises on sound and really unique features and deep "open" synthesis. Tempest is definitely one of them, with all its limitations and bugs.
It's quite important to inspire musicians and open "new horizons".
The feeling of "now everything is possible" is very important.
When Tempest was announced it was really a "H*%$F*#(!" effect. Nothing else around was as inspiring and serious on features at that time. I was really excited and still keep some of this excitement till now.
I used and use lot of other things like Elektron / Roland / some boutique and modular things, but I'm not sure if something as interesting and "complete" as Tempest showed up ever since, most of the tools are "marketing oriented" and feels like made for Kindergardens, to make mediocre stuff.
Probably only in modular and software worlds there are some breakthroughs, but still it lacks this "complete solution", "hands on" design. I'm talking about something like MPC was for hip hop in 90s - a "sonic canvas", so here same idea but for modern "experimental" approach, still with top notch sound, analog/digital hybrid generation.
I also really like what Dave Rossum made with his resent Assimil8or module. I tried to contact him and wrote many times that this is a brilliant sampler and if it completed with analog filters / effects / sequencer / memory, it could be that "holy grail" of modern grove station / instrument / call it whatever.
So, yeah... I don't think Sequential has to stop here...
