Using Constant for Gain/Volume.

[lalalandsynth]

I am using multiple samplers in a Synthesizer group.

I need to control the volume of each sampler , as far as I can tell I should probably use a Gain-Constant Modulator as I cannot use a simple gain and I am assuming that using the sampler volume will not give me smooth /crackle free gain.

My question is , can I get a log/db response for the constant , it sounds like its linear?

[d.healey]

Why can't you use simple gain on each sampler?

[lalalandsynth]

There is no FX option on each sampler when used in a synthesizer group.

[d.healey]

Why not put it on the synth group then? or do you need individual control?

[lalalandsynth]

@d-healey Because in each group there are 3 samplers , and I need Individual volume control.
I guess I could just not use a group and link the Adsrs between them ?
That is the only reason I am using a group .

[d.healey]

Do you need to control the volume while sounds are playing?

[lalalandsynth]

@d-healey yes, its a drawbar system .

[d.healey]

@lalalandsynth Then I think constant mod is your only option, I don't know a formula to convert from DB to intensity though.

[lalalandsynth]

@d-healey Ok, I guess I will not use a group then .

Question on voice amount.
When I use a group - 3 samplers per group.
The total group gets 256 voices.

When I use the samplers individually i,e not in a group , each sampler gets 256 voices.
What would you recommend for the voice amount for each sampler ?
I am assuming that is a CPU issue and I need to economize ?
Each sampler can only play 2 octaves , but polyphonic.

Any thoughts on this ?

[d.healey]

@lalalandsynth Hard to say, but yeah the lower the better in terms of cpu

Use this scriptnode-powered time variant modulator in each sampler for a simple real-time gain control (adjust the smoothing time as you like and setup the parameter range to be as logarithmic as you want to):

As for the performance question: the synth group is a bit more efficient because it handles the voices together, but you won't get too much CPU optimisations there as the bottleneck will most likely be something else.

@Christoph-Hart Awesome ! Thanks !

@Christoph-Hart Should I set the Converter to Decibel to gain and use a decibel scaled slider or a 0-1 slider and Gain to Decibel ..... OR do I use the skew factor .
How exactly do i get a db response ?
