D-50 101: Linear Arithmetic Synthesis explained. by TSF

YouTube via TheSynthFreq | February 20, 2011 |

"Linear Arithmetic synthesis or L/A synthesis is whats behind D-50s awesome sound, here I explain the process of how D-50 works.
These 3 main parts of D-50s awesomeness, is:
PCMs- pulse code modulation (there are 100 of them stored to ROM)
Digitally Generated WaveForms- Saw and Square waves (remember a Saw has even and odd harmonics, a Square has only Odd harmonics)
Subtractive Synthesis- the most basic theories for 'subtracting harmonics' in a structured way'.

"An incomplete but viable instrument. 12tet markers, microtonal markers, octave switch (beyond hearing in both directions), string count change. The distorted metal sounds is the only one that's right at the moment though. Using itablapro for rhythm as always."

"Hello again from asThMatic.What we have here is a circuit bent Atari 2600 with a new copy of synthcart.This is a great program for making music its alot of fun and the bent atari makes it even better. The bends to the Atari 2600 are a 1/4in outjack added with great sound quality. A volume control knob that give you great range over the volume. And 2 rca jacks one for video and one for audio the video one can run the visuals from the atari to and t.v, projector, etc with a yellow rca jack.

Lastly a Piezo contact mic which can be used as a microphone to pick up all types of samples. A little about myself I have been a underground artist for about 14 years.I am a glassblower,circuit bender,graffiti artist,and musician.On dec.5 2006 I had a severe asthma attack after passing out from lack of oxygen I had a seziure and bit down on my tongue making it hard for my wife who was 7 months pregnant at the time to give me CPR.After my heart stoped she still stayed calm and got the idea to cover my mouth with her hand and breath in through my nose saving my life and most of my brain. Since then my life has been about art and sharing inspiration.I have been blessed with the artist around the world that trade inspiration with me.Thank you and feel free to ask any question to asThMatic. This Atari is in great working condition and comes with a power supply. Its very rare to see a atari with this many bends added all of which really add to the synthcart."
