"Solar Prominence lll" A new synergistic approach to Laser Lumia
.
Audio/Lumia synergy - Theory.
Well....Time to add my 02 cents !!! I have long thought that we need a new approach to a coupling between music and Laser display. I believe that music is the more powerful force in generating raw emotion.....and the addition of Laser display amplifies and compliments that emotional response.
.
SO...assuming the above is true...my thoughts turned to Lumia display vs. abstract generation, traditional beam or graphic display as the additional Laser display method to be coupled with music. In my opinion...Lumia is akin to " Visual Gregorian Chant ". One can view Lumia...but...not really focus on the pattern changes. The patterns vary...but in many ways remain similar. But yet, on some subliminal level,...the Lumia display is recognized and has a therapeutic impact and value. Although Laser Lumia is surly visual eye candy, I speculate it does not demand the level of concentration that other Laser display art does.
.
So...now...if the above is true....Lumia display that is coupled with audio music content would allow the music content to take centre stage....but...still allow Laser Lumia a powerful synergistic impact....to raise the overall emotional response...to a value greater than the individual value of the addition of the two components ( Music + Lumia )...= Synergy.

Audio/Lumia synergy - Applied practice
.
About 6 months ago....I started building a Lumia machine... and at the same time I began talking with the fine folks at Foxtone and Sweetwater Music...suppliers of Synthesizer equipment. My goal has been to have the link between the music and the Lumia display...to occur on an automatic, yet controllable platform. I envisioned that the music content would enter the system...and the Lumia RGB would react...without intervention.
.
To this end, I purchased a Eurorack Sound envelope follower and a LVO ADSR envelope modifier. My goal is to have a sonic event be connected to a single channel of an RGB Lumia generator. SO....I want a single channel of the RGB....say...the RED line, to be automatically coupled to the source audio....and be a function of the music amplitude ( volume). The Blue and Green line will be adjustable in output....but not linked to the audio content. The test unit is set up so that either the Red, Green or Blue can be the..."accent color". When an audio change event occurs...whichever R,G or B....responds in power output....But in a special way !!
.
IMNSHO...it is very critical, as my interpretation of what the nature of Laser Lumia should be is .....SMOOTH....NO quick changes in display intensity !! So...if the music sound volume has a rapid ramp up/increase....the "accent color" follows suite....but in a smooth response. This is where the ADSR unit comes into play. This unit accept the Envelope follower unit CV input and then modifies the sonic envelope output, thereby changing the ADSR signature. ADSR stands for " Attack, Decay, Sustain and Release "
.
The desired sequence of Music~Laser intensity coupling is not a one to one rate.....but an " elastic " coupling. Let's say that if there is a rapid increase in the music sound level, the Laser output will respond...but...slowly....following the volume / amplitude....with a much slower response....and a much longer sustained display/reply. So...the Laser output will follow a modified audio ADSR envelope....and will modulate in a much more extended response.
.
System audio path as follows;
Audio/Music signal into the Euro Rack Envelope Follower
Envelope Follower signal into the LVO ADSR unit
Modified audio sonic envelope into the LSP Driver units
LSP Driver units modulate the R,G or B LD output level as a function of audio amplitude.
.
System Laser section
.
LD compliment consisting of Dual 63196 Red, Single NUBM07E Blue and Single NUMB01T Green. IMNSHO....these are great lines and will have a combined output over 5W. Standard Dichroic combining. The beam propagation is adjusted to very, very slightly off-axis alignment. The result is a generation of several colors...outside the constraint of only Red, Green and Blue. Disclaimer: This set-up was suggested to me by DSLI Jon. The idea is that in the central section of the beam arrangement, a color blending will occur. Blended gradations appear in various proportions/colors. On the mid to outer section annulus, pure R,G and B is distinct.
.
Lumia Distortion section
.
Unfortunately, I am not at liberty to discuss the details of this section due to proprietary commitments. I will say that dual Lumia distortion disc's are employed and that the RPM speed is greatly reduced. The resulting Lumia patterns are quite beautiful and remind me of pictures of Solar prominence. In the area of Lumia generation, my path has been greatly advanced and schooled by Clickamouse ( Mike Gould ) for which I am greatly appreciative !!!
.
Conclusion
.
The end goal for all this is a new approach to Lumia display which is linked to music content. A system engineered to deliver a degree of Laser Lumia effect, but that effectively coupled, in an " elastic " relationship, to any audio musical content.
.
When I get closer to testing all the section/systems I will publish some pictures...and likely a video. I do not know if such an approach to a Audio=>Lumia display will work or has been tried before ?????? Laser Lumia...by its very nature is slow, unfolding and graceful !!! I want to preserve that graceful quality of Lumia yet add/link the power of music to it.
.
The Eurorack units have many, many patch possibilities and have many control dials. In a fashion....one will be able to control/modify the ADSR sound envelope. All these controls on the Eurorack units will deliver a great amount of diversity in selecting the nature of the ADSR envelope modification that is feed into the LSP drivers. ....which in turn modifies the Laser Lumia display...SOooo...this set up is a " Controllable Laser Lumia "
.
I want to sit back...truly enjoy the music...and appreciate the linked Laser Lumia display. I do not want the Laser display to distract, in any way, from the sonic beauty and wonder that is so valuable and appreciated !!! I want the Laser Lumia to be...well...a visual....delayed, sustained echo of the audio/music content. I am hopeful, this system can deliver that synergy of Music + Laser Lumia. Work continues on the project. Wish me Luck !
