Yes, I Have updated to Version 2.50.
At 120 bpm, it is fairly locked in for around 29 bars. But as you slow your bpm down, it starts drifting more and more. Down to 70 bpm it gets off by almost half a beat after only 4 bars. The sources I have tried so far are the Selah Effects Quartz Version 2, Protools Midi beat clock, and Logic Pro X midi beat clock.
Unfortunately it's enough drift to not only be noticeable, but un-usable at this point in time. Mainly when using square wave tremolos and sequencing effects. I'm also unable to "reset" a pattern on a bar's downbeat by pressing the TAP foot switch once. A feature, that was on the M series. If there was a midi cc assigned to restart a pattern without altering the tempo, this would be extremely helpful.
Also, if the TAP LED aligned with the preset/global tempo. (This was pretty reliable in the M series pedals). As of now, it drifts.
Also, If the HXFX unit could tell us (confirm) what tempo it is tracking and receiving from the external clock source, this would be immensely helpful.
This is a terrific unit. I would love to see these features added as I'm sure many day-to-day users would. It would be very useful. Thanks for your time!
