Hi all,


Actually i'm learning all reverb opcodes because i'like this kind of sound.
But each time, using the reverb process i get also a lot of "out of range"
samples, and i need to decrease my amplitude : finally the sound without
reverb is stronger than with.

Is there any way (except to turn the speakers or increase alsamixer !) to
manage this ?


Cheers,

Sergio

Are you sending each instrument to its own reverb, or are you summing the instruments and sending the sum to one reverb?

Just some passing thoughts, but I think the mixing setup is going to
depend upon the needs of the individual piece. In the past I've used a
reverb mixing setup where instruments route signals to a reverb UDO
that has a single wet/dry mix control.  This would mean the wet/dry
mix is global to all signals that feed into it.

Linda's suggestion is similar to something I was thinking of using for
future work, where each instrument has an individual wet/dry control
that determines how much of the signal goes to a reverb and how much
dry goes directly out.  The wet/dry control value would be set for the
instrument. (In my case, I am considering this in context of Blue's
mixer, where I would use Sends and a reverb subchannel.) I think this
would be fine for setups where an instrument maps 1:1 to a location in
space.

If an instrument is used in multiple locations, representing something
like different performers using the same instrument types in different
places (i.e., violins 1-8), then note-by-note control, as Linda
suggests, makes a lot of sense.  I think Jan Jacob's works, which has
a lot of control per grain of sound for amount of reverberation and
other spatial parameters, exemplifies this kind of approach.

Anyways, hopes this adds some ideas to the approaches already
suggested in this thread.

A minor thought:  if one is using a linear reverb (that is 
reverb(a+b)=reverb(a)+reverb(b)) then having each instance doing its own 
reverb is more friendly for multicore rendering as it avoids dependencies.

Hi Michael,


"Are you sending each instrument to its own reverb, or are you summing the
instruments and sending the sum to one reverb?"


I'm sending each instrument to his own reverb ; i'm never summing 
instruments to sending the sum to one reverb. In all cases, for the moment
i'm working strictly, each time, on an only one instrument (and its reverb).

Also no problem of by error together playing instruments  : i detect that
immediately.


Many thank's,

Sergio

Hi Linda, hi Steven,


Great thank's for your detailed explantions,  including especially the idea
to construct separately each note (or frequency) with its instruments and,
maybe, reverberators.

Hi John,


"having each instance doing its own reverb is more friendly for multicore
rendering as it avoids dependencies."

Yes, but where can i set something on to make my rendering multicore ?


Cheers

Sergio

Hi Victor,


Many thank's ! I ignored really that we have this kind of system feature
(thank's also to John !) available. I turned it to on ; i suppose that it's
not necessary to declare many threads ? By example more that one thread pro
instrument is, in most cases, without interest, as i think ?


Cheers,

Sergio
