I really love the wobble filters etc and idea behind Reaktors Lazerbass and was wondering if something similar exists where instead of bass sounds, you can put your own aif or wav sounds in.
So for example where the oscillator, the sine,saw etc is just replaced with your own sounds :-)

That would be killer :-) I would love to build it but I am only 2 weeks into Kyma now :-(

Hi, I just had a look in my Reaktor and searched for the file, yet I could not locate it.

However, I suspect this is wavetable, this is easily achieved with CrossFadingMulticycleOscillator.

You can start by loading the standard kyma waves to get a feel for how it works.

You can then move on to getting snippets of waves (one or two cycles works well), editing them in the Kyma sample editor, using the interpolate function to make sure they are the right size (go with the default setting)
You can then try out allsorts of possibilities. Do look at your results with the scope and spectrum analysis. It can be very revealing.

Once you have this cracked, you can then join them together and use the index parameter to select different tables!! (think waldorf synths (MW + Q etc)

Shout if you want an example, my explanation might be as clear as mud.

wobble_start.zip

 
I am by no means an expert on the wobble bass phenomena. I did see a thread (perhaps on MuffWigglers) about Massive and how people were using the synced mult-segment envelopes to achieve the sweeps.

My thought was, "that's nice, but perhaps could do something in Kyma that would be perhaps more realtime playable". I hadn't gotten around to fully implementing that idea but since you asked, I whipped the attached example this morning which may lead you down a fruitful (or not) path.

As you can see, it is 4 LFO that this cycled through based on a BPM rate. At each stage you choose the waveform from a table and the ratio that the LFO runs at against the master BPM.

You could also implement this easily in a single Oscillator by using an array in the Index and Frequency field. The reason I choose this example was because you could easily swap out each of the 4 inputs quickly with another source, say noise, an envelope generator, or another audio signal. From here you can extend to more than 4 steps easily.

This is a quick example and not fully tested so all caveats apply.

thanks will check it out today. I just love the demo here because I am not interested in playing it musically more as sounds / fx http://www.youtube.com/watch?v=RrGNZss4sEg&feature=player_embedded

Its under synthesizers in Reaktor 5 :-)

Try using a Replicator (with 3 or 4 copies) on an Oscillator with DutyCycle and detune the frequencies to within ~0.1 hz or less of each other and sweeping the !DutyCycle. This might give similar results to what I heard in that video. The waveform should be a little bit complex (not just a sine wave). Better yet, put the Replicator on the CrossFadingMulticycle as per Charlie's suggestion.

p.s. In response to the first post, a Replicator on Samples with Frequency set to something like:

default + (0.01 * ?VoiceNumber)

will laserize your own sample instead of an oscillator.

I'm not a Reactor owner, but from watching the video I'd say the top display is showing the frequency response of the filter we are hearing. This might give you a clue how to emulate the sound.
