|
Jarek,
I am putting together a design that will use MP3 and Midi tones. I have sliders connected to the Midi elements for volume control. I have a Sound Reader and PCMAudioPlayer combined for the mp3 playback. I attached a slider to the Player element to adjust that volume.
When I adjust the MP3 volume an odd thing happens, the volume on the midi elements changes as well.
when I was checking this out I looked at the Volume control panel and discovered that the wave volume not the SW synth volume slider controlled the midi and MP3 Volume. Is this an issue you have been aware of or could this be an issue with my sound card?
Any trouble shooting tips?
Thanks
George |

George,
the Volume input on the PCMAudioPlayer changes the Windows system mixer volume (not just the volume of this element). So if you have other sound playback in your design, then you may prefer not to use this input at all. And control the volume of signals which come to the PCMAudioPlayer only (for example by inserting ExpressionEvaluator and multiply the signal by the value 0..1 provided to the second input).
So no, this is not just your sound card. Using this input may be fine, if the PCMAudioPlayer is the only sound playback in the entire design.
