Re: timing on DAW side. I believe I've got that figured out. For a given set of DAW audio engine parameters (sample rate predominantly), there is a delay, typically static, that encompasses DAW Midi Beat Clock send, external MIDI instrument receipt, note playback, and DAW audio capture. With a distinct transient sound played on a downbeat, like T click, the distance between the supposed DAW grid downbeat and the recorded, delayed external instrument downbeat sound is measured in samples. Then, in the DAW, the Midi Beat Clock sent to that external instrument, is advanced earlier, i.e., to be sent earlier by that delay amount. In my test yesterday at 44.1kHz, my delay between my system and Tempest was 203 samples. In Pro Tools, I set the Midi Beat Clock offset to -203. Once that's set, it's wonderfully tight. Even listening to two clicks grooves. When I hear the T slave click in the pocket of the Pro Tools master click, it's really nice. When in Beats mode, I star triggering with Quantize Beat off, various non-quantized two bar Beats I sequenced, all 3 things in sync- it's _______ magic.
That is why my current obsession is to ascertain drift isn't happening as a result of the Tempest.
Drift is: when the tight lock-step timing relationship between the two timing devices, here DAW and Tempest, drift apart, in a gradual fade-away kind of way. A cool musical effect in certain vistas, but not for tight rhythmic collaboration between DAW and Tempest. Recreating drift as a drummer could be fun, purposefully painful to the rhythmic ear.

A cool feature for a different timing-based instrument:
Drift Glide.
Set glide amount. Engaged like Roll button. (Either engaged only when pressing, or for on/off for successive presses.) When engaged, Drift Glide releases timing lock, by Drift Glide amount.

Toooo much rambling. And you likely know that DAW setup stuff. I decided to flow with it in case someone else was curious but to shy to ask. All in the name of driftlessness. John tells us that's in the Last Beta. That is good.
