DESCRIPTION

This is an experiment to try and make a simple interface for a polyphonic additive synthesis.

The amplitude or level of each the 32 harmonic or partials can be drawn on the graph. Also each can be de-tuned and each partial has its own envelope generator with ADSR settings in separate graphs.

Think of the graphs as sliders in a vertical row, each control in line with the harmonic at the top.

Additive synthesis makes some very complex sounds and is better suited to acoustic timbres. Having individual envelope control and tuning for each partial does allow for considerably more tonal possibilities than subtractive synthesis.

It does take some experimentation and more thought about how a sound is constructed than typical subtractive sysnthesis as well.

The filter is not essential for a lot of the patches as filter type effects can be created using envelopes on upper harmonics.

Warning* it is a bit of a CPU hog and may cause problems on slower machines.
You can increase or decrease the number voices depending on CPU. I have it running with 8 voices at 45%

The Kawai K5000S was always a machine I wanted to have, but never came to really buy it, somehow this 3000-parameter-and-10-knobs thing scared me. Good that it did :-) Thanks for your effort.

OK sorry for the previous rant. I just uploaded a 16 oscillator lower CPU version for those that are having trouble getting this beast to work on their computers. It is called PolyAdd Lite.

Turn off the morph function if you are having trouble with CPU overhead. It is the Morph ON/OFF switch. Then set to 1 or 2 voice polyphony and you can also set the sample rate down to 22kHz or whatever your sound card supports. I am surprised that so many people have spent $500 on software and then are running it on a $200 computer. Dell has a nice Quad core machine with 8 Gigs of RAM and 1 Terabyte HD for $800 or less. Do yourself a favor and take advantage of all that Reaktor has to offer with a decent machine.

CPU murder....even at lowest setting.

Look's great I like this kind of additive synth, unfortunatly my computeur does not look to be enoug powerful to run it. but I'm shur it's great.

I just updated it to V1.3 which now includes a morph LFO. Pick any two snaps and morph with LFO depth and frequency. Turn off panel morph switch to edit snaps.

This is the first time I see an additive synth that is not only a great idea, but also great to use! You might consider having noise modulation per partial for some dirt.
