Apologies, got my syntax in the wrong order

Hi
read the helpfile for [vline~], that message means "go to 1 in 5ms, then after 5 ms go to 0 in 20ms". Remember, that impulse has no 'real world' physical characteristics of its own, it's just a filtered noise burst.

Hi
you could shape your own impulse, using noise~ into an envelope and filter. Not sure how that will affect your output frequency spectrum though

imp.pd

And I'll also look at PlugData thanks

thanks for the advice @alexandros; I might revert to vanilla.

. . . but if I launch PD by loading a .pd file, the menu bar remains correct and intact - strange behaviour from the purrdata application launcher

Hi
Purr Data is behaving strangely since I recently updated it. When I first launch it, it appears fine:

But when I create a new patch, it changes to this:

Note the missing menu bar items.

Am I a newb, is this the wrong forum?

@jameslo Not derailed! Just expanded and extended

I just want to thank everyone for the detailed responses here, which has inadvertently but interestingly diverged into a slightly different topic. It makes interesting reading.

You mean how it works internally? Probably a modulo function.

Hi
I'm not sure what the PD equivelants are, but in Max I would have done this with rate~ on a central phasor. I think (it's been a while )

Hi
if you share the important elements (Bela --> PD) from your patch here, we'll certainly have a look - I'm not familiar with Bela myself but have experience using Arduino with PD.

yep! you're right, i'll keep chipping away at this, thanks

Thanks for chipping in. I should have mentioned a few things: this won't be a commercial or professional product, just for my own noodlings (I was looking at Behringer's recent line of HW synths and thought, why am I spending money, just build one in PD). So, the detail you mention isn't critical to me.

I could of course just make two different versions and see which one I like the sound of; plus, doing it that way will throw up any issues along the way.

Thanks again
Brendan

Morning good people,
I'm making steady progress on a simple polyphonic MIDI synth, and the post title says it all really. I have a single phasor driving a variety of oscillators (rect, saw etc), and am about the polyphonise (?) it. Would you put that phasor inside the clone object, where the shaping functions will go, or not? An 'outside' signal will of course go to all voices, and there may be phase issues with mutiple copies if I put it inside.

Kinda answered my own question there, but would love to hear your thoughts

PD-Pi

from Miller's book " In case you were hoping, subtractive filtering can't remove foldover once it is present in an audio signal."

The learning continues. . .

Thank you so much for these, will get stuck in later today.

I went with this - it is subjectively okay

Hallo
sorry to bang on about this - I have done further reading and cannot find a simple solution to antialiasing a square wave oscillator. There is of course the [square~] object in Purr Data - should I just use that?

Many thanks
Brendan
