Saucer (ride or crash)

All the percussions, except the hi-hats and cymbals, were generated synthetically, it has an oscillator circuit with a dedicated filter and an envelope curve. The hi-hats and the cymbals were 6-bit samples, compressed and combined with an envelope volume curve (and adjustment) to allow slight modifications. Thanks to the analog circuit, various aspects of the percussion sound can be modified (tone, attack, decay).It also has a function called "accent" (accent); a primitive way to humanize the rhythms. In a simplified model of a drummer and his drums, the volume of sound created would depend basically on the speed at which the drummer impacts a specific part of his equipment. a human drummer can emphasize certain notes by playing them with greater volume, and the accent parameter provided a means to enhance a particular step.

My object favorite it is the guitar electric , I think  it is a great invention properly of its versatility .Exist different type of the guitars depending on  to the brand or models there vary its sound capacity , to be able use it adequately we need a amplifier and an audio line out .

I have my guitar about 7 years ago and I use the stratocaster model for left handed whit this model i get the sound that like me, this guitar model has been used by great guitarists in the history of the rock music like Jimi Hendrix , Steve Vai , George Harrison between others .

I think that this electric instrument widens the perception of sound and technique due to the great power it gives when playing it .

 I was play in a team sports named Cobresal for 4 years , but finished to pull out for reason of study in high school.

After finishing my secondary education i decided to study art thinking in that always i felt it ability to produce art, so I entered the university and now I am studying art and painting, in the process of the career I have learned a lot and I have improved in my technical and theoretical quality in relation to the plastic arts .

In a future I hope continue to dedicate myself to this practice and keep learning even more.
