audiopower depends on cpu load?? |
|
|
i use an unexpanded g2 and recently found out that when i use a lot of dsp power in a peformance, lets say i use 3 slots for this, and use a fourth just for audio, a simple stereo flanger perhaps, the audio sounds very thin!
when i only use slot 4 with the audio patch, the sound is a lot thicker!! how does this come? is there also a sort of audio poly / bandwith depending on how much cpu is used? thanks in advance. |

Could you post the perf and/or wav recordings of the flanger with only 1 slot and 4 slots enabled? |

you have to look at the voice count of the slots..probably some of your patches get a reduced voice count when you enable a 4th slot and alter theire sound because of that |

the problem is that it alters the audio path |

Is this internally generated audio routed through slot 4 or external-in audio? If it is the former, 3phase's suggestion might still apply. If it is the latter, well, that would be odd. Short sample for purpose of demonstration? |

I'm guessing it has something to do with polyphony/number of voices too... try using an FX area for your audio ins - you shouldn't hear any difference then (when you add other slots). _________________ Sheridan

Assuming you use no envelope after the osc, and that's what the mp3 sounds like :
No ... its not the same single osc but you have 32 of them, all with a different phase and all parellel and summed on the output. And that does two things, it smears out the shape and it will get louder.
In a patch using an envelope before the osc goes to the output it's different, as as you have to press a key first to hear the output. and you can't press the same key 32 times simultaneously.
Hope that helps explain it, but if not please say so. _________________ Jan
also .. could someone please turn down the thermostat a bit.

this explains it really well.
But would this be some kind of bug or is there some logic behind it?
but now i know it doesn't bother me it actually sounds a bit cool
thanks Jan |

It is not a bug, it is the working mechanism of the voices. Add a voice and the voice area gets duplicated (and so it needs DSP resources to be duplicated as well), but the FX area stays mono. All voice duplicates are automatically mixed in the output modules. _________________ Jan
