Sounds awesome.A manual reset on the accumulator is gonna be great!

Question: will our saved presets survive this firmware update?

Yes, we’ve got a preset versioning system so they should carry over


Holy shit… They really did think of everything on this one.


We still have a few things in the pipe. :wink:


Take your time, seriously. Let the public catch up.


This is fantastic! Is it possible to set accumulator limits per stage for the mod lanes? For instance on stage one, limit could be 8up/0down but on stage 4 I’d like to limit it to 3up/2 down.

No the limits are per-track settings. This plays better with the addition of the new Track based accumulator mode, keeps things a little less complicated, and easier to keep track of.

That didn’t work for me. All presets gone after the update unfortunately.

Question 1: is there a way to get them back? (Assuming the answer is no, but I still have to ask as there were a couple good ones I had saved)

Question 2: is there a way to backup presets to avoid this next time updating?

Other than that, awesome update!

Let me look into it, it could be something small like detecting which preset can be loaded.

  1. Probably, just don’t save over the slots.
  2. Not yet

Thanks, that’d be great!

PM’d you, hit me up

just wanted to say thanks! @slowwild sorted this out and all the presets are back.

Intellijel you rock!

2 Likes is live, and will show your old presets again. They were not lost, just hidden from you, this update will bring them back into view!


Thanks for the heads up @TMOTM!

Where are the significant changes in the manual with this update, Wes?

The Accumulator section would have gotten an overhaul, as did the Accumulator itself. Other than that, the rest of the notable updates would probably be covered by the change log above.
