Re: [EXS] Answers to -- What difference between 'instrument' and 'instrument ECO'? + Microtuning & portamento + ECO

2005-03-16 by Charles Lucy

HI Steve;

One posting to answer your three recent questions;-)

1. "ECO" stands for economical, and is a lower "quality" sample file to 
reduce byte space and load time.

2. By definition JI intervals are always integer ratios; e.g. 3/2; 4/3; 
5/3; 5/4; etc.
The aim of JI is to minimise "beating";
(if that can considered to be a reasonable intention is another 
question).

Another downside is that using JI the interval sizes vary depending 
upon the supposed positions of the interval in the scale.

See:

The very good microtonal dictionary/encyclopedia by Monz for 
definitions of terms used in tuning theory:

http://www.tonalsoft.com/enc/encyclopedia.aspx

3. Using EXS you can change the portamento rate using the "Glide" 
control which determines the time it takes for the pitch to slide from 
one note to another.

see page 545 of Logic Pro 7 plug-in reference manual for details of 
"remote, Glide, and pitcher" parameters.
