a personal note & some Qs

greetings fellow nerds, first off i want to reitterate how important it is to have such a strong & dedicated community obsessed over getting the most out of the DIY studio, beyond the era of the bedroom studio. thanks to you i have been able to turn my salvaged gear into my own world-class hi-fi system.
i've used the drivers for a year now but am only beggining to implore KX to achieve what i have dreamed. Now I understand how the DSP and routing works, thanks to reading ever single post on the board. I need to learn to code & compile, beggining here. The only programming i ever did was c64 basic, so this i will learn, following your examples, and sharing sensibilities...so...THANK YOU! I dedicate my life to optimizng my surroundings and resources by most economical means, as an investment into a life of luxury & liberation thru uninhibited artistic expression. i think we all share this idealism, which is why we refuse to be limited by technological sell-outs.
Anyways, it goes without saying. I have a few technical questions.

1. Is it possible to turn my cd-rw into a component that would record to disc in real time. E.G. direct from CD thru optical ins, more importrantly from the turntables via DSP as preamp because the unaffected sound is too dry.

2. Is there a better way to make a phone preamp? Currently I use the APS Comp Rev (gain at 42, threshold at 0, the rest to the left.) > timbre with full bass > tubesound. Possibly eliminate the timbre by using filters? There seems to be a bit of distortion from having such high gain on the comp.

3. I want to create the classic Rhodes sound with my suitcase model, bypassing its own amp, therefore taking the passive signal from the keyboard straight into the board via DI boxes & chorus (unsure exactly how DIs effect the signal). If anyone has tried this with KX please send me screenshots.

4. How to get the cleanest signal from my mics when using an XLR to 1/4 inch adapter? Is this a true balanced signal reaching my 1/4in on the livedrive? It seems too noisy.

5. has anyone made a DJ crossfader plugin with a/b switches to mix like 4 sources? independent gain controls would also be cool.

6. Is there a reason y'all use cubase rather than logic?

Thanks for reading, help with any of these points is greatly appreciated.

To answer your last question: There is a reason (for me, at least) to use logic and not cubase with kX drivers: logic works fine with it, even with four cards installed were cubase is unable to handle this...

Yes, me. Now 'bundled' with the drivers, but can 'crossfade' only 2 in and 1 out...

Do you mean a preamp for turntables? If so , don't you need a RIAA outboard Preamp
for freq response correction and to bring it up to line level?

> I want to create the classic Rhodes sound with my suitcase model, bypassing its own amp, therefore taking the passive signal from the keyboard straight into the board via DI boxes & chorus (unsure exactly how DIs effect the signal).

I dont have a suitcase model Rhodes, but if you take the real passive signal of a Rhodes
(i.e. right from the coils) the impendance of the used DI-box, all parasitic capacitance in cables and the coil's induction will act more or less like a lowpass with a resonance peak at it 's cuttoff point.
I would use a High Impendance DI ( ~1meg ) and low capacitance cabels to avoid this.
Personaly I've made a High Imp. Fet preamp/buffer right in the Rhodes avoiding the above.
On the other hand; some ppl prefer the lowpass coloration. As always; there is no absolute rule.

hmm....I had planned not to post code here anymore.
Oh well,..what the heck here it goes;

;----------------------------------------
;4-Stereo channel DJ mixer + A/B mix
;----------------------------------------
name "DJX4";
copyright "LeMury(c) 2003.";
created "08/09/2003";
engine "kX";
comment "DJ 4ch X-fader + A/B $nobypass";
guid "2d8e752c-d0d5-4f64-a6f2-9102687568f1";
output outl, outr;
input A1L, A1R, A2L, A2R;
input B1L, B1R, B2L, B2R;
control XFade_A=0.5, XFade_B=0.5, X-AB=0.5
temp La, Ra, Lb, Rb
interp La, a1l, xfade_a, a2l
interp Ra, a1r, xfade_a, a2r
interp Lb, b1l, xfade_b, b2l
interp Rb, b1r, xfade_b, b2r
interp outl, la, x-ab, lb
interp outr, ra, x-ab, rb
end;
;--------------------------------------------------------------

I'm not a DJ but I assume that A/B thingie is used to 'switch' between the two mixes.
I left the 'gain' controls out for now.
I coded this in a few minutes so give it a try and let me know.
If you don't know how to use/register this code, just ask and I make a DL link
or explain it to ya.
