Configuring the Headphone levels in Bela using SuperCollider

Joaku_Sotavento

Hi everybody, I am posting this because I have exhausted all resources I have.

I am implementing some custom filters based on biquads through Super Collider in Bela, but I have the problem that I do not find the way to increment the gain in the headphones niether by the Bela IDE nor lines of code in Super Collider. I change the values and it does not show any perceibable change in volumen.

I am using the following lines in Super Collider to setup the input gain and the headphone level:

s.options.pgaGainLeft = 10;
s.options.pgaGainRight = 10;
s.options.headphoneLevel = 0; // is in this line where it supose to change it, but it does not sound different.
s.options.speakerMuted = 0;

If any one has some information about it: How to setup the hardware gains in Bela, I will apreciated a lot.

In advance thanks so much.

As far as I can tell, setting the volume works OK. Just a heads up: valid values are from -60 to +3 and positive values are only supported on the latest dev version of the Bela code, so the board you have will probably only allow values between -60 to 0. These values are attenuation (or boost) in dB. Also note that you have to restart your program for the settings to take effect: editing them while the program is running won't affect them because these are initialisation settings. Also note that these settings are only meaningful if you are using a Bela, BelaMini and/or BelaMini Multichannel cape. If you are using any of the CTAG capes, these won't do anything because those do not have headphone outputs.
Let me know if you problem persists.
