So, I finally received a response from DSI pertaining to LFO Sync Drift when set to Play/Beat mode. The solution to make it work is to allocate a voice to the sound. It seems to be working when I do this but the issue is now I have just used up a voice. It is not an ideal solution considering that I am now using 1 bar patterns and 32 sounds for live performances but it gets the job done. It would have been nice to have had an explanation as to why but this may be an unsolvable issue when using the voice allocation algorithm.
I was also in communication with Roger Linn about helping the push. Through no fault of his own, his hands are tied since it is Dave's resources at play and not his.
Below is the complete email from DSI (note...the support person "Dave Mech" just copied and pasted an order email thread devoid of a simple acknowledgement or "Hello." *sigh* Courtesy is non existent these days. I left the entire email sent to me unaltered. Please see below:

Oh and of course program a 4/4 kick to here the effect

Dave Mech, Mar 9, 02:37 PST:
And lock the the sound to a voice of course

Hi Carson, thanks for your quick response!
I might have not explained the problem well enough
. The sound is locked to a voice indeed. When in beat restart mode it does start correctly when switching beats. But the lfo itself is drifting away. As in, it's not synced to the bpm the Tempest is running on. So after 1 loop of 8 bars you can already hear it is not tight anymore. And it gets worse very fast. Try the following:
- bpm 130
- osc 1 on saw
- lfo 1 on Rev saw, sync, rate: 8th, restart:beat, destination: osc1 frequency. Set LFO amount to something that is musical and won't leave you with a headache during testing.
- set env mode to ADSR
- set amp env amount and release to the max
- set env aux1 destination to amp env release, set aux1 sustain to 70 and aux1 release to 80. Aux1 amount to -127
- set seq length to 8 bars.
Now record 1 sustained note (hold it a couple of seconds) .
For good measure, switch to a different beat and back to the one with this setup to make sure the lfo is synced the way as you describe. Now keep listening for a couple of loops of 8 bars and you'll hear the lfo drifting away from the bpm it is supposedly synced to.
Hope to hear from you
thanks again,
Cheers, David

Hi David,
I'm sorry to hear that you are encountering troubles with your Tempest. I would be happy to assist you with it.
To begin, it's good to note that when the LFO is set to sync with BEAT or PLAY reset mode, the sound must be assigned to a specific voice for the LFO to run correctly. Once the sound is assigned to a specific voice, then the LFO should reset and sync correctly thereafter. Furthermore, with the LFO set to reset to BEAT, the LFO will only sync on beat transitions and not from the play button.
Let me know what you find when the sound in question is assigned to a specific voice and I would be happy to continue to assist if need be.
Thank you,
Carson

Hi,
Glad with the Tempest. Amazing machine
. I have a problem though. The LFO's don't sync well in beat and play modes. They drift away while running a sequence. Im running the latest beta OS and voice OS etc. (see my previous support ticket).
You can replicate this by selecting adsr mode and recording several long notes on one sound and modulate level or pitch with an LFO synced in 8ths and on beat or play sync mode.
Any idea why this is happening on my unit?
Cheers,
David
