new to max/msp obviously.Can anyone help me on how can I do a pulse width modulation on objects (cycle,saw etc) other than rect ?

thanks in advance

[rect] generates PULSE waveshape. PULSE waveshape does have PULSE width.
saw waveshape and sine waveshape does not have pulse in their waveshape, so you can’t even set it’s width, while it just doesn’t exist.
You can shape their waves in other ways (for example morph SAW into TRI into RAMP), but you just can’t modulate their pulse width, if they don’t have any…

All the info you need is in the help files for each :)

happy waveshaping

I hope he doesn’t accuse me of being an in-formant

it will cause some headache at first when you build a PWM-able cycle-based oscillator yourself, but you will end up with a solution which works with ANY thinkable waveform – plus you will learn a lot from doing so.
