Looking forward to these!

Thank you!

Hi,
I'm using the Scope 4.0, it seems to get the missing dsp files issue!
Anyone?
How to deal with it?

Oops, I missed it! Thanks, Shroomz.
A question:
How about the "VM-42 Valve Mixer" device? It seems be missing the DSP file too!
Can I use the same ECC83SIMB1.dsp or I need other DSP file?

Same dsp file, different sounding device :)

...

... in order the output of the Tube Warmer to be perceived as equal in loudness with its input, you have to lower the output about 3.2dB...

Hope this helps

Sounds cool!
I have tried a few songs through the "VM-42 Valve Mixer" and Optimaster for final mastering tracks, it seems to get nice and warm characteristic sounding!
I like it!

Thanks

Cool :)

Rodos, that's strange because I'm getting readings of -5.0dB at the output when feeding it a 0dB white noise or sine wave test tone from the control room module. I doubt the control room module lies... ?

Before finishing any of these devices we need MUCH more accurate metering, so I'm gonna make hi-res decibel accurate meters.

Shroomz~> · Post by **Shroomz~>** » Fri Jan 12, 2007 10:12 pm

infact no, I'm wrong. The control room must be right & the metering on the Control Room should actually be fine for testing purposes as far as I can tell. No need for new meters

vO.7 of musrgio's tube warmer is on page 3 of this thread. Boosted output gain to level out the input & output signals. That was done using test tones, so it should be damn near accurate.

Good night :)

Dear Shroomz your tubewarmer 0.7 is not calibrated.
Maybe you have done the opposite !
You raised the output !
Needs to be lowered much...
Around 3-4 db !
Thanks
Dimitrios

Dear Shroomz please substract a little from the drive control.
The tube distortion is a little more than needed...
How much is the control now ?
If it is 3 make it 2
Thanks !
Dimitrios

Don't use meters but rather use your ears!.. The Tube Warmer works in a way like a compressor, reducing peaks.. So if the peaks in original audio and processed audio are the same, the processed one will be louder.

If you want to use meters to accurately measure the difference, then use an RMS meter and not a Peak meter. I can do that for you, but later at night today or tomorrow.. Gotta go now..

Cheers!

Thank You Brotha' Man Shroomz,
My electro mechanical device's and samples go through the Scope mixer, i.e. Rhodes, Wurlitzer,D6,B2003,etc. I will give your Tube device it's own AUX in the STM1632, so it can add the added effect which has escaped me so far.
Hopefully this will also smooth out the peaks on live vocals as I hate using software limiters.

Brotha' Man Shroomz,
I tried this out thoroughly w/ ASIO module > ECC83S, etc.
The way it works 4 me best, is to put it in an AUX on STM1632, and send all electro mechanical emulations and samples into their own channels where each AUX can be seperately set. If I wasn't using the Pro 3t rotary w/ tubes this would also be on my B2003, as it sounds much better than CW's saturation solution that comes stock.
I was wondering, since I have just got Wolf's MIDI Tool Box, can I change the preset box's title from empty to ECC83S or something similar?
I have been looking 4 something like this 4 a while, almost bought Dynatube. I'm glad I waited, cause I only needed something w/ a filter, and tube in, tube out. I would kill to get a mic pre that emulates the Crane Song Solid State. But your device is exactly what I needed on my Rhodes, and Wurlitzer samples. The Wurly sounds like it's playing through a Twin Reverb, and the Rhodes barks like a good DAWg should. Sounds like the old Suitcase Stage '88 I use to play on.

Excellente Trabajo Cavrone,
U Da Man.

My DAWg's Now Are Pack Hunters,

Hi there,

Jimmy, I'll fix the preset box name when I make a version with presets.

Dimitrios & rodos, oops my mistake guys. I messed that last version of the warmer up because it was 6 am & I was really tired. Been busy with a new device today, but I'll fix the warmer & give it it's own thread as soon as I can.

Hello Shroomz!

Ok, I have done my tests with the Tube Warmer.. It's more complex that I thought it would be!.. I had forgotten that a tube IS NOT a linear device, but reacts dynamically in its own way...

So.. the results of my tests.. I used the Tube Warmer version 0.5 board 0, and the Celmo Pro Tester to provide me a White Noise signal. I recorded in Nuendo the original white noise and the processed version of the white noise at the same time, and with the same duration. Then I ran the statistics of each file and got the following info:

PEAK RMS Avg DC offset INFO
-0.89dB -5.77dB 0% original
-5.03dB -6.36dB 1.22% processed

-4.86dB -9.77dB 0.05% original
-5.03dB -7.35dB 0.68% processed

-9.87dB -14.77dB -0.05% original
-5.05dB -10.56dB 0.01% processed

-14.88dB -19.80dB 0% original
-9.68dB -15.44dB 0.04% processed

As you can see, the peaks seem to get limited to a maximum of -5dB. In each case where the original signal was peaking at -15dB, -10dB and -5dB, the processed signal was louder. But when the original signal was close to maximum, peaking at -1dB, the RMS average of the processed signal was was quieter.

I think the Tube Warmer colouration sounds best when the signal fed to the tube Warmer is peaking around -5dB, afterwards it starts to distort the signal in an apparent way... One probably has to make a lot more tests in order to understand the exact way this tube emulation works and to find the perfect number for the output gain.. But to my ears the -3.2dB I have suggested is good..

I guess that my potentiometer settings on the tube dials @ 7, and 8 o'clock positions seconds that motion.

My Ears Love This Device, As Well As My Rhodes, Wurly, and D6 Also Demonstrate.
