Don't put your volume too high at the start! This goes from clean nice sounding plucks to full on washes of changing frequencies that go all over the place.

This is a demonstration of a set of modules I wrote for the axoloti/ksoloti patcher.
The arbitrary spectrum oscillator uses a frequency shifted feedback to create a spectrum where the partial spreading can be controlled in both upper harmonics as well as harmonic divisions and octaves. It can also be thru-zero frequency modulated and it's output is in a sine/cosine configuration to always provide you the real and imaginary part of your generated spectrum. As the module is internally polyphonic and has an inbuild AD-envelope, up to 16 spectra can be stacked upon each other, each with their own envelope timing. This also makes it great to use as a fm-modulator as multiple related spectra can be stacked upon each other to mimic plucking, brass and rubbing.

The second module is a combination of delay, neoFM, pitch shifter, frequency shifter and a doubled (nested) allpass filter to create delayed feedback that can completely change it's frequency content and diffusion over time. This all also works as a real/imaginary pair, so even the outputs of the delay are still in a real/imaginary relation for further frequency shifting processing or other things that might use that relation without the need of any hilbert transform to split signals into a real/imaginary pair. Delay time is cubically interpolated to provide as clean as a modulated&pitchshifted delay as possible (both delaytime and pitchshifter make use of this same function as these are summed before calculating the exact delaytime+pitchshifter positions) and can be modulated up to audio-rate with a dedicated "neo-FM" input that is set to a small maximum modulation width.
