Hi everybody,

I just noticed a very strange behaviour concerning [phasor~].

It started when I wanted to replace [phasor~] with [creb/blosc~]. Normally they should sound pretty much  the same except for the obvious aliasing problem of [phaser~].

Then I noticed that in some cases they didn’t sound the same and in others they did. I finally found out that it had to do with the level going over “1”  - only while being doubled.

While [creb/blosc~] sounds the same no matter if I boost the levels higher than “1”  [phasor~] starts to cancle it’s sound. With a single [phasor~] it’s no problem but two of them will give you trouble.

Since Pd is working with 32 bit float this shouldn’t really happen – and doesn’t with [creb/blosc~].

Can anybody explain this?

I have my test patch attached.
