Compressor Ouput vs. Master Volume knob

[bpsafran]

Hi everone:

I received my Genos2 before the weekend and it indeed sounds crystal-clear and with well-separated voices compared to my Tyros5.  I am also enjoying the 1600 registrations that Yamaha has set up since they are a good guide to the new voices, styles and effects.  My Tyros styles and registrations worked perfectly (so far).

My question is:  Is Compressor Output the same as increasing the Master volume knob, or is there a difference?  I would like to know which I should optimally control to get an appropriate volume.

Thanks,

Sam

Hello,

the compressor reduces the possible dynamic that can be achieved. This causes the overall signal to appear louder. But this is only useful for music that really shouldn't have any big differences in volume (dynamic).

The compressor has a few controls, do not mix them up.

The compressor threshold control adjusts the dynamics and any "pumping" compressor style artifacts, whether they be desirable or not.

The output level control of the compressor will not color the sound in any way and has the same effect as adjusting the master volume, yes.

I myself have added a compressor to the main output and used the output level to reduce the volume when using USB-audio since the G2 hardware volume control does not adjust the USB-audio level.

Dear Konaboy,

your port is very interesting to me.

When adjusting a Style in Edit mode, It can be that I need to increase the volume of a single track. Sometimes even setting the track volume at 127 it is not sufficient.
So I use a work around, by adding the Compressor effect to that track, and adjusting the Output Level of the Compressor until I get the desired volume. Apparently I never had problem of sound quality by using this method.
But I read some post where it was said that using the Compressor would alter the sound.

Your post was related to the general use of the Compressor, influencing any part and playing mode. And you specified that this way by increasing the Compressor is like to increase te volume.

My question is, does this behavior (increase volume without altering sound) is the same when I use the Compressor as described?

Thank you

My periodic PSA... 

Yamaha don't mention it, but the Master Compressor is a parallel compressor. (You have to dig through the Montage documentation to discover this.) A parallel compressor raises the quietest levels and is intended (usually) as a mastering effect, i.e., putting polish on the final mix.  https://www.soundonsound.com/techniques/parallel-compression

If people want to use compression as an effect (in EDM, hip-hop, or other modern genre where pumping is sometimes desirable), they need to add a compression insert effect to an individual part like the drums or bass. At some point you'll discover, unfortunately, that Genos/PSR doesn't give access to side-chain. Montage/MODX can do side-chaining.

Then, again, you might not care at all... 

All the best -- pj
