"GAIN" CC controled

Hi Cris,
There is no CC to assign to a button for gain.
I made the %%gain (for complete sample sets) or %gain (for individual samples) for this.
The idea is that you tune your sample sets only once to get the volume levels of all sets/voices all sync'd volumewise, preferably at the highest gain without distortion (play loud while using using a lot of notes). This way you can safely switch voice or set - no gain adjustment needed.
See More info -> Controlling the volume for more details and Configuration parameters for an explanation of %gain and %%gain.
For gain there is a discrepancy between the GUI+menu and the parameter values (there is factor x100 between them):

• the GUI+menu range 0-300, with default (no gain adjust) of 100
  
• The parameter ranges 0-nolimit, the default is 1, where 0-3 correspond with GUI+menu range 0-300. So the config parameter allows for values that cannot be set with the GUI+menu..
  You may need a value below 1 (your post suggests 0.1 or 0.15).
  

Basically the only reason for gain in the GUI+menu is to be able to tune faster as the the sample set doesn't have to be reloaded for every test value.
Good luck, Hans

Hello Hans!! Great, I get it, so... only with writting the parameter "%%gain=0.1" in the samples folder, it should be enough for me, no matter what the GUI+menu says...it's like an override.
THanks a lot, man!
