Asymmetrical Signal Processing – #1
The idea behind this project is to split positive and negative portions from an audio signal for individual processing. A splitter can be mad easily in Reaktor or Max/M4L, using Min/Max modules.
I ran some tests under Ableton Live 8 using Max4Live as splitter on Send A (Positive portion) and Send B (Negative portion). In order to perform this technique, under Ableton Live, is mandatory to set the output of audio channel to be processed on “Sends Only”. I tested this technique on an already mixed electronic track. The original track sounds good and punchy but even “flat” in terms of dynamics and space. I tried using different compressor settings for each part of the signal.
As already mentioned it’s very easy to get a distorted signal specially when the mix have few elements (i.e.: only kick+hh parts).
When the song start pumping with more instruments, here comes the magic: the mix now is wider and more dynamic without losing punch. Adjusting compressor parameters and channel levels dramatically change the final result, more often with heavy distortions.
I have to find a way to get rid of this drawback and test this technique with different effect types and working on some audio and video proof of concept to show.
Stay tuned,
Luca
The Modular Piano 2010
This project started as an experiment in summer 2009. I worked on this sound for months, trying to push the boundaries of subtractive synthesis together a wise usage of sampling. The final result is my first commercial library based on this synthesized, different and hopefully new piano sound.
The Modular Piano for NI Kontakt can be purchased as download at a price of €29 on Progsounds.com

Modular Piano
While programming my first library I ran into the need to have an acoustic piano sound. Since I don’t have a real piano to sample, I decided to synthesize it from scratch using “traditional” subtractive synthesis technique. This is my first good result and has been achived only by using basic oscillators, filters and so on. The only downside is the limited polyphony due to heavy CPU usage so I sampled almost every key and mapped them into a sampler in order to make this sound more usable.

The Stethosphone
The Stethosphone is an “alternative” miking tool built using a couple of electret mic capsules mounted inside a cheap stethoscope. This instrument is very useful in order to experiment with surface recording from any object and it is good even as new way to record instruments such as guitars, drums and so on.
