hi in the cvs-version of qsampler (or liblscp, etc.) the volume sliders do not work. Values of 0 or 100 have effect, but no values between. This applies to channel volume sliders and global volume slider. It seems, that volume is muted (or set to 0) for values < 1. Christian S. suggested setting LANG=C : "That's a local dependent bug (comma vs. point for decimal separator in floating point numbers)." Unfortunatly that had no effect on it, when I tried (recompiled) it. as soon as dragging the volume slider, it is jumping to the 0 position, with the exception of 100% so my option is 0 or 100%, but nothing between. in the qsampler window I see: 22:19:19.320 Channel 0 Volume: 0.74. 22:19:19.568 Channel 0 Volume: 0.74. 22:19:19.616 Channel 0 Volume: 0.75. 22:19:19.656 Channel 0 Volume: 0.76. 22:19:20.000 Channel 0 Volume: 0.77. 22:19:20.017 Channel 0 Volume: 0.78. 22:19:20.032 Channel 0 Volume: 0.79. ...but the sound is muted... (only ON at 100%) the same happens, if changing the % value in the spin-box (number-box) of the channel strip Emanuel Rumpf
LANG=C is not meant when you recompile, it's meant to be set before launching qsampler. However this issue should be fixed proberly, so that this workaround is not needed in future anymore. I try to fix it in the next days. *** This bug has been marked as a duplicate of 59 ***
