Hi Johan,

Thanks again for your response.

Ah. This is bad news. I did not yet manage to update (file not found
error), but I did replace pow~ and groove~. Although replacing pow~ cured
my other problem (thanks), replacing groove~ did nothing. Seems to be a
bug then, no?

>Question (though): what would be de advantage of using signals for
>looppoints?

Answer:so that you can change them without clicks. If you're using the
sync signal to put an envelope on your loop (fadein, fadeout), you can use
sah~ to change your loopoints only when the envelope is at 0. Otherwise
you get clicks:if you change the looppoints mid-loop, it changes your
sync signal instantaneously and so jumps to another point in your envelope
(click).

hi Stefano,

i don't know if you feel like spending more money - but Spark from TCWorks works
with vst plugins (including Pluggo), and you can also use it as a realtime fx
processor. the plugins are setup in a 4*6 matrix (i think - i'm not in my studo
right now), which means that a degree of routing is available. it's a nice


programme - more info at

James...

i got an email from David Z about a week ago in which he basically said that
this _is_ going to happen, but that it's non-trivial, and will take some time.
more than that i don't know.

Try : FFT size (eg. 1024) over Eulers Constant as max. value

then Magnitude over max. value = scaled Magnitude

(don't ask me why, but it works for me and looks somewhat reasonable)

There are many ways to do this with Max/MSP
try putting your sfiles in a single folder in the max folder
(if sfile name not reckognized, put the folder in the pref path)
use sfplay~ or better sfcontrol~ with two voices.
write your sfnames in as many messages boxes you want
trig one box or another with a select object controled by velocity or whatever.
That could be a start
try also using buffer~ and groove~ or other ram sound disposalls for short
samples.
Good luck

Subject: Pluggouts

Pluggo is very nice but :
Using pluggins with a sequencer is such a pain.
Allright with protools but vision obliges you to open boxesinboxesinboxes
and to change bits&nuts&vindows through themselves
and finally crashes your machine when it begins to be slightly interesting
because my DSP can't support the hassle.
For me, making music isn't playing a game of cards castle.
That has to be said (une fois!)

Why not doing 'pluggouts' instead ?
that meens separate application
I did some with MSP and truly it's much more fun.
I which someone would develop some good interface
which would be able to run any pluggins
including pluggo and commercial vst pluggins.
I haven't found it yet.

The GRM in Paris is on one, but for the time beeing,
it doesn't seem to be compatible with pluggo.

Let's vait and see said the 'soucis'.

Yours

Subject: CPU and pcontrol problems


Hi-

I'm working on an MSP patch with 8 patchers of "sound-makers" heading for
one dac~ -all with a toggle box hooked to enable $1 then intopcontrol
outside of the patcher. I use a coll to select which modules are "on." My
beginner's question is: when all the patchers are "off" and I toggle the
dac~ on, my CPU usage is around 18-20%... when several of the patchers are
on it only goes up a percentage point or two. I've checked by looking into
the patchers that are "off" and can't see any activity. Maybe just a dac~
breathing uses that much CPU? UMAX/G3 board, OS 8.1, plenty of RAM.

Thanks for any advice.

John
