Is there a logical/ historical reason why if you have something like
aMod poscil 10, 5 
aCar poscil 0.3, 440+aMod 

the aMod input values become hz and times per second? Is there some material someone
 can direct me to about this? thanks-

aCar will swing from 430Hz to 450Hz 5 times a second. This is just a vibrato effect, similar to a cellist shaking his finger on a bowed string.

Npot sure I understand the qurstion.  The ame poscil comes from Precise 
OSCILator and giving a frequency inn Hz is very nirmal.  What is the 
problem?

My question is, how does the first input (10), which is normally the amplitude input, become +- 10? Also, how does the amplitude input become an input for frequency? 

another question I have now is exactly what makes poscil more accurate than oscil?

thanks and sorry for all the stupid questions-
Joe

the first poscil generates a stream of values between -10 and +10 
sinusoidal -- 10*sin(wt).  It is not an amplitude, just a function
When added to 440 it generates 440+10sin(wt) which is a slowly varying value 
from 430 to 440; tat is then used as a frequency.

Thew it interpolates between values not stored in the table.  poscil uses 
floating point index and oscil uses integer as I remember.  In time-critical 
performance oscil is aster and may not be sonnnically too bad..... Oscil3 
uses cubic interpolation rater than linear.

Ah. Very well explained. Thank you.

"slowly varying value from 430 to 440"

If sin(pi/2) = 1 and sin(3pi/2) = -1

Then it should be varying values from 430 to 450, except poscil is reading from negative uniformal sinoid table.
