Yes, Derek,
that formula makes absolutely sense. The funny thing is that the level with the - 0.5 was identical with [creb/blosc~]. It should have been half the level. Strange!

Have a look here:

My basic formula is
[*~ 2] | [-~ 1]
Best! D.

Hi Derek,
that's it !!! I just subtracted 0.5 from the [phasor~] outlet and now
it
behaves as expected. Thank you!
Now I have to find all the [phasor~] objects in my patches und change it there. Using [blosc~] is just too expensive for simply producing some
slight
"dirt" modulations.

Did you try graphing the output of the combined [phasor~] objects? To me, it seems likely that the lack of a zero-crossing in the [phasor~] waveform would create a large amount of DC offset, and perhaps that is what you are hearing. [creb/blosc~], [osc~] and pretty much any other audio waveform generator all have mostly equal amounts of positive and negative energy in their waveforms. Only [phasor~] is the weird exception and wasn't even designed to be used as signal source anyways. I'm quite sure it was mainly intended for use in driving [tabread~]
objects.

Do subpatches with several [phasor~] used as a audiosignals produce a different result as intended without summing up in total over "1".
