DESCRIPTION

3.1-------------------------------------------------------------------
outputs were some way outside Blocks spec at higher sample rates - should be fixed.
Please report if the blue and purple don't sound right to you at higher sample rates
3.0-------------------------------------------------------------------
* Added sample rate compensation, so relative levels of the different noise colours are now consistent across different clock rates.
* The flashy GUI was giving me headaches, so I scrapped it and created something a bit more 'pro' for this new version.
* fixed a bug where RND generators sharing a seed was causing some subtle phasing.

2.1---------------------------------------------------------------------
Heh, I got my colours wrong - my blue should have been violet!
So here's a quick GUI update going through blue to violet (and a minor improvement of pink through to red as well)
2.0---------------------------------------------------------------------
After checking the output of v1 on an analyser, I saw that the frequency response was nothing like good enough, so this is a complete rebuild using a different approach.
*now features noise from red through pink, white, light blue to blue...
*frequency response is fairly linear across the spectrum throughout the range.
*much more useful, much more 'correct'
*lower cpu requirement.
-------------------------------------------------------------

1.01 - oops, a 'VCA' logo appeared from nowhere!? now deleted!
---------------------

An experiment to see if it was possible to generalise the voss pink noise algorithm to allow a variable slope frequency response. It worked well enough to be useful. It might not be 'correct' - but this 'aint no peer review journal so...

The basic idea is to use an additive approach, rather than the more common filtered white noise implementation.

Now I can wear my violet glasses look thru the world!

i don't want to change the interface too much, so just the potential to one extra control tops...so four filter options and one envelope, but i find myself "not quite getting there" with the noise section on some tweaks...if so inspired to contribute on it, i would gladly write you into the credits...it's an option, and i am not going to make a noise section change anytime soon otherwise.

V2.0 generates red pink, white, blue and violet separately, then cross fades between them. Pink and blue use the Voss-McCartney algorithm with is an additive kind of thing (blue is just differentiated pink). Red is filtered white, and violet is differentiated white. This would be used for percussion, but it's only a small part of the puzzle. You'd get more mileage out of tuned noise, using e.g. combinations of multiple enharmonically tuned oscillators with filtering, FM, various envelopes etc.

"The basic idea is to use an additive approach, rather than the more common filtered white noise implementation." because i think this, in addition to then post filtering, is going to yield the kind of noise flexibility percussion calls for.

Thanks ColB, this is an advance that can breath some life into noise circuits of all sorts...critical to percussion, i am now thinking of moving the LFO rate and depth knobs up, on a DAWDrum revision, and putting in a horizontal noise color fader...let static noise sources be a thing of the past, YAY !

The world shines in more colours - thanks again Colin.
