When i build my stuff in Max MSP,all Sounds great.

When i compile the stuff as VST the Sound is completly different from the Max MSP version or Standalone Build ??

It Sounds like a doubled Signal ( phase problems )

I go step by step thru the patches but i can`t find a mistake.

Did anyone know the Problem??

I use MAX MSP 4.6.2 PluggoJr 3.6.0 G4 400,OS X 10.4.7 M-Audio Fast Track Pro,Live 6.0.1, Logic Express 7.1.0

Patches.... there`re a lots of big Patches inside, thats the Problem.But maybe a Idea :i build my own Combfilters with MSP

maybe there is the Failor.I send this CombFilter Patch a bit later.

as far as the comb patch is concerned, i think there might be problems with the initial values set in the objects. the gain goes too high and its as if the dac is on the verge of "blowing up".

when i copied and pasted into max, i attached a saw set 74hz to the input and a gain to the out... first thing it did was to come on and fade out as the gain got higher. it worked better once i tweaked the values of the effect.

i guess it depends how your patch loads up by default in pluggo.

also, i dont know if u are aware of the comb~ / teeth~ objects which implement the comb filter for you!

finally, your patch might have a problem with very small delay times (less than 10 ms). i seem to remember from the manual (somewhere in there) that tapin / out cant do delays which are very small - or less than the time it takes for ur cpu to calculate one signal vector, which i presume depends on your signal and i / o vector size.

about Comb~ i think the Comb object has no LoPass inside.

Thats the reason why i build my own LoPaCo.And the Comb~ has no external Feedback possibilitys.

Hi Justin,what you tell sounds logical.
So i initialize on a lower level.:-)

And the TeethFilter ditto.

yep i would choose some values other than 1, especially for the feedback sections... because 1. is full feedback which will quickly overload. in fact you should probably limit the feedback to a range of 0. - 0.99. then it should prevent it from blowing up.

as far as the lopass is concerned, i understand what you mean with the lopass not being part of the actual feedback chain... might be nice if C74 made a new comb filter object with the lopass in the feedback chain? fingers crossed, could be done for the next major update of maxmsp (v.5)!

i dont think we need a new comb object with sidechain I/O.

how would you want to connect it? you will create a buffer

underrun if you put something into it.


When it`s not possible to conect a a Filter inside, what kind of possibilitys i have to made the combfiltr working with MAX MSP objects? See my little Patch above.The important feature from the

comb~object is the inital gain, because it`s feeding the feedback

inside the comb~.How can i realize this.With my Patch i run into trouble.:-(

Hi Roman,
One question about the Comb~object.

if your "comb" only needs to do "delay", you can use a [teeth~]

instead to do the same - and then make a feedback loop around it like its done in the tapout helpfile.

you will still have to make sure you dont connect a

signal to itelf by doing teeth-send-receive-teeth

(and eventually substract the current vectorsize in 

miliseconds from all but the first delay time if you want

THX for reply.I would like to try out your soloution.
