Damnit! I just noticed LePou released the beta now! 
Thank you LePou! Will be working with Lecto Beta this weekend for sure!

I'm finding it hard to notice a big difference between orange and red. Red seems a bit less fizzy, a bit more lowmids?
I'm REALLY digging the Vintage channel for rock tones. Really fucking nice character.

fuck, this is GREAT. thanks a LOT! exactly what i've been waiting for all the time.....kicks the shit out of podfarms rectifier sim if you ask me.
running perfectly stable in win7 64 bit / reaper 32 bit over here. cpu consumption is also pretty low even with 8x oversampling turned on - which really seems to help the high end btw, 2x is a lot more harsh sounding imho.
this thing slays, thank you so much!
btw, quite a difference between orange and red imho. very similar to what i remember the real recto to be like.

lepou you're the fuckin baus!
im gonna test this out VS my 2 channel dual rec next time i record it!
already sounding like it from memory though!
again, you deserve all the praise in the world!

Then I don't know why it rang a bell because I don't listen to KSE.

Here's my guitar tone competition 3 tone using lecto (NOT on leads and solo), I just copied the same knob positions as in legion (for comparison) and adjusted the resonance control to fit Red Wire impulses (I probably overdid it because there's a part where the riffs get too boomy):
Lecto chain: Ts808 beta (onqel) + lecto (red, modern) + lecab (Redwire rectifier impulses)
Legion chain is: legion (red, lead) + lecab (Redwire rectifier impulses)
bus for both: LP/HP + cuts and boosts
lecto mixdown
legion mixdown
lecto guitars
legion guitars
(files are being uploaded ATM)
Lepou, I noticed that the output is WAY quieter than legion (I had to max it out and boost 3 dB on the guitars bus), will you be making it louder in the future?

do get technical
Seriously Im not an electric/electronic guy so I maybe wrong on some points but anyway.
From what I have understood through my readings on tube power amp, as the load of the power amp tubes are the speakers (via the output transformer), they (the tubes) will react according the speaker/cabinet impedance. And this impedance varies as a function of the frequency in that kind of way.
http://www.acoustics.hut.fi/dafx08/papers/dafx08_17.pdf
The actual gain of the power tubes is related to the load they are connected to, and the bigger the load the higher the gain. So without negative feedback, the frequency response of the power amp is gonna be more or less similar to the frequency dependence of the speaker/cabinet impedance. Negative feedback tends to flatten the output by taking back to the input of the power amp an inverted portion of the output signal.
If we go back to the Recto, the main difference between the vintage and modern mode is the absence of negative feedback on the modern mode, so a not flattened frequency response. From a simulation point of view, if one wants to model the difference between these two modes, a load as to be modelled and connected to the power tubes. Simlpe. That's what I did in LeCto.
Now we need to add a speaker/cabinet simulation after the amp sim. The preferred choice is to use an IR. What is included in an IR ? The frequency response of the power amp, the speaker/cabinet and the mic. What if the IR has been captured using a tube power amp with no (or just a little amount of) negative feedback ? It will have that big bottom characteristic of the speaker/cabinet resonance. And what if the speaker/cabinet/power tube interaction is already modeled in the amp sim? The end result is gonna be a big uncontrollable bottom.
Do you see what the problem was and why I add to implement the resonance knob to control the low end ?
Hope I don't talk bullshit !!!

Sounds great! I tested it a bit strangely though: Cream Tube + LeCto (orange modern, maxed volumes, settings at noon) and then into the FX loop return of my Powerball, and then playing through a Mesa 4x12"

Just tried it in a cover of the song Refuse Resist (not finished, without vocals & solo )

Just tried it, one side is modern mode, red and the other vintage orange, but I am not hundred percent
sure, my short-time memory is fucked atm Only 15 minutes to try and record it, so it could be
way better.
Really liking it so far, but it's very sensitive when it comes to impulses, liked some harley benton ones
the most with it so far, used it for the bass, too, with the same settings that I used on the right
guitar track, just put a low pass at 5k and a deep cut at 500hz.

Tried it together with Nick Crows 7170 and it was awesome, but I just wanted to post a sample, only
with LeCTO.

I decided to test it out on one of the practice mix thread songs.

Left and Right gtrs are both Red Modern.
Left is going into LeCab with the free lolzgreg impulse and Burny's Br Joint impulse blended together.
Right is going into LeCab with the same lolzgreg impulse, but blended with Catharsis s-pres8.
HP at 90, LP at 7.5k. Some narrow cuts at 123Hz, 3.8k and 1.2k on the Right. Narrow cuts at 123Hz, 4.8k and 2.5k on the Left. Both have High Shelf boost of 4dB around 6.6k.
Loving the sound of this beta, by the way.

Hey Lepou also why is the output on the sim lower than other sims you got? For instance compared to Lextac i have to almost put both the "master" and "output" knob to the right to get them at equal volume... i mean this can easily be fix with the fader but just wondering.
-Appreciate the work!

LePou, your answer makes complete sense, and shows that as a developer, you're thinking about how the user will deal with different impulses. It's great to see you're taking the time to add a feature like your resonance control and understand why users will need it within the modeling domain. But I can see how many users will say they want a lot of "resonance" and just crank it no matter what the impulse. It probably should be called something like "impulse compensation" instead.
