Anyone know why the last three points on this table are 0?

f1 0 128 -5 .1 25 .3 25 3 25  2 25 .5 25 1

I get the same results with GEN07 and I do with GEN05, but the problem
is less noticable with much larger tables. The following code
illustrates the problem.



-+rtaudio=jack -odac -b4096
;n -d


sr    = 44100
ksmps    = 32
nchnls    = 2
0dbfs    = 1

instr 1
iCnt init 0
iLen = ftlen(1)
until iCnt>iLen do
 i1 tab_i iCnt, 1
 iCnt+=1
 printf_i "Index:%d Value:%f\n", 1, iCnt, i1
enduntil

endin



#define Size  #4096#
f1 0 $Size 7 .1 [$Size*.2] .3 [$Size*.2] 3 [$Size*.2]  2 [$Size*.2] .5
[$Size*.2] 1
i1 0 1000

Indeed. That was a simplified version of the one that was creating the
problem. So should the same thing apply when the distance between the
points is 25.6?

Answering my own question..I assume so, given that the the ordinate
points must be integer. Next time I should read the manual first. I
would have thought however that if n1+n2+etc was less than the table
size, then the last few points would be set to the last given y value.

Sorry, our mails got crossed there. I understand what you mean, and
now get that they must be integer values. Thanks.
