Hi, 

working on an example for the mac opcode, i think the a-rate and and k-rate
are in the wrong order:

ares mac asig1, ksig1 [, asig2] [, ksig2] [, asig3] [, ksig3] [...]

should be:

ares mac ksig1, asig1, [, ksig2]  [, asig2] [, ksig3]  [, asig3] [...]

Is this right?

The csd that should prove this, works, but commenting out the other "mac"
produces a lot of distortion - watch out for your speakers/ears/neighbors
when trying!




; Select audio/midi flags here according to platform
-odac     ;;;realtime audio out
;-iadc    ;;;uncomment -iadc if real audio input is needed too
; For Non-realtime ouput leave only the line below:
; -o mac.wav -W ;;; for file output any platform

Bumping....

i like to upload an example for mac, but to my opinion the order of the
arguments is mixed up.
what shall i do, change the manual to this?:
ares mac ksig1, asig1, [, ksig2]  [, asig2] [, ksig3]  [, asig3] [...]

Perhaps someone can have a look at the code and tell me if i made a mistake
with the example or the code has to be changed somewhat?  

greetings
Menno

the code says 
    ans mac a1, k1, ....

Could be counter intuitive, and could be changed

Sorry for delay in answer -- been in receipt of unstable net for the
last week

Hi John,

the counter intuitivity is not the problem. 
When i use the opcode in the way it is written in the manual i get this
carbage (please listen at very low volume!):
http://csound.1045644.n5.nabble.com/file/n4477014/mac.ogg mac.ogg 

it works fine when i exchange the order to:
aout  mac klow, alow
http://csound.1045644.n5.nabble.com/file/n4477014/macright.ogg macright.ogg
