I tried again, and now it works much better than before... so I guess there was something wrong before.<br>
<br>
Well Claude, it seems it almost works as the [triangle~] object.<br>
<br>
Do you guys know about this one? It comes in some external library.<br>
<br>
Were you who did it anyway Claude? :)<br>
<br>
[triangle~] works in a similar fashion, it goes smoothly from inverse sawtooth to triangle and the sawtooth depending on the parameter (from 0 to 1).<br>
<br>
The thing is that Triangle corrects the DC Offset, which could easily be done in the expr. But now I may start to sound like an obssessed DC Offset maniac.<br>
<br>

[phasor~] [r~ shape]<br>
[expr~ if($v1<$v2,$v1/$v2,(1-$v1)/(1-$v2))]<br>
<br>
<br>
I tried that, but it didnt actually worked, I just get actual<br>
sawtooths, and<br>
no real triangles.<br>
<br>
<br>
Sorry for the shortness/lack of explanation, 0<shape<1, where 1 for<br>
phasor, 0.5 for triangle, 0 for backwards phasor.<br>
<br>
considering shape as a constant, obviously you get weird results if<br>
you modulate it, but that's half the fun:<br>
<br>
0.0 <= input <= shape ~> 0.0 <= output <= 1.0 (rising ramp)<br>
shape <= input <= 1.0 ~> 1.0 >= output >= 0.0 (falling ramp)<br>
<br>
Hope this helps,<br>
