Ha! It's a PITA that takes awhile to do. Here's why - I posted this on the CX3 thread too. You have to reset the amps in CX3. So....
This would be a good time for everyone not up on how amp resets work to read Yek's excellent Wiki entry about amp block hard and soft resting and what values change and what do not under each method.
For example, if I want to use fw25 and now must reset a single LiveGold preset with four amp channels ABCD - especially a hard amp reset using the preset manager - after the reset, I will have to go back into each amp block and manually enter the old key parameter values for the following stuff bulleted below to get a true A/B comparison between how the preset sounds on fw25 CX3 versus the prior version on fw24 CX2:
- possibly the
presence, depth and a brite cap value (if I altered),
- the i
nput EQ Lo Cut (goes to zero, I use this all the time to clean up goofy low end, at least 66Hz cut and sometimes more)
- any amp block
graphic EQ values changed (will all go back to zero)
-
Speaker Thump, comp and drive (although the editor's great batch processor handles fixing those universally easily enough)
- if you alter preamp or power amp tubes, or play with negative feedback or Supply sag (I don't usually mess with these)
- any
input dynamics or
output compression settings (they will go back to zero/default I use that for cleans a lot), and
- any non-default
pre or power amp tubes or
variac changes.
Also these change:
- the
amp boost value (defaults to 12db on reset, I often use 8db to 10db tied to CS2 switch, depending on amp),
- the
amp saturation value (defaults to 4.0, which sometimes is way too loud if used with my CS5 switch, - you have to custom do values for these per amp to control the volume (I use Ideal type but still have to do this or a preset can clip)
A hard (and some soft) amp reset will erase most of those above that I often tweak to produce a LiveGold preset -- even though it preserves some basic gain and T/M/B stuff.
A soft reset keeps more of your original settings - but not all.
The now-defunct (no longer supported by developer) FracTool was nice when we had it, because it let you "freeze' some of these custom settings listed above to the amp block when you reset an amp.
So - just be aware, if you often change parameters in your amp block like these above, an amp reset is going to write over them and reset them to default -- and you'll have to adjust them back to taste.
(And all this is why it takes forever for me to produce a TonePack update after a major firmware update... because it's all manually done by me to the specific amp am playing each time -- I don't just globally do "set parameter" stuff with a batch processor and hope it works out).
So, as always...if you like your presets now, you don't have to change. Before you try a new firmware like this that is explicit in how it will alter your existing sounds -- back up your presets first, and keep the Cx2 firmware they work under saved, and you can always revert backwards later if you like.
