Joystick Axis Generator

Joystick Axis Generator

Hello All,

The JAG is a new module design that takes any two input 
voltages, and makes all the inversions and combinations 
available simultaneously. It is a two input, ten output 
folder/twister/combiner.

You could also look at it as a kind of Cartesian barberpole 
generator.

They original X and Y inputs are passed through to be used in  
the patch. Or a second unit with X and Y switched will give 
another 10 functions shifted by 90 degrees. The output fuctions 
can also be used an inputs to another JAG for really bizarre 
shapes.

The most obvious application is for panning. The corner 
functions supply control for the 4 VCAs, and the edge function 
supplies a correction function for equal power panning. The 
function is used to boost the output in the middle of the pan, 
eliminating the power drop in the middle.

Run the other way, it is useful for Joystick controlled MIXING. For 
example, running 4 waveforms from a VCO to 4 VCAs allows you 
to mix them with a Joystick. This is also called "Vector Synthesis" 
since the Joystick voltages can be replaced with envelope 
voltages or LFOs. The 4 waveforms could also be the output of 4 
different effects units or other waveform processors.

Another example is to use two envelopes as the inputs. This will 
produce 10 envelope "variations" that can be routed to 10 
different parameters in a patch (PWM, filter sweep, filter Q, 
crossfading between two filters, waveshape control, envelopes 
times etc.). 

If a Joystick is used, it gives you control of patch timbre in real 
time. Fun when you are running a sequence and dynamically 
morphing timbres. For example, the four corner or side functions 
can control all 4 attack, decay, sustain and release times at 
once. So the single Joystick can give you all possible envelope 
shapes mapped across the Joystick plane.

Complicated, mysterious, yes, but I also think it will be great fun 
too. There are 9 LEDS on the faceplate that indicate the output 
voltages. A great light show, but it also give an intuative grasp of 
what is happening.

wow, wow, wow, wow, wow, is all i can say. it really looks like you 
have surpassed yourself again mr. richter! the possibilities are 
frying my brain already. when can we order, and when can we see a 
piccy or hear some .mp3 files?

all the best,

gregg.
