Hi there

I'm pretty new to PD, this is the deepest I've got with it so far.

I'm following along with Andy Farnell's Designing Sound book to create a patch for the sound of bubbles.

It sounds wrong (and not like it does in the example from the website), but really high pitched, but it should be the same frequency that he gets in his example patch.

Also I get an error... random: no method for 'float'
and I can't work out what's causing this.

To solve the frequency issue I tried getting rid of the hi pass filter and adjusting the envelope but that doesn't help. I've been analysing it for hours now and can't work out why it's so wrong.

I've attached a picture of the main patch and all the abstractions copied in next to it.

Thanks a lot

@BioMannequin Hi,

re. the error, you can use menu > find > find last error to see what's causing the problem. In this case inside [bubblepattern] you have connected the last outlet of [select] to [random]. That outlet outputs all floats that don't match any of the arguments, and [random] only accepts bangs at its inlet.

@weightless As @weightless says....... you have that error. Reducing the frequencies helps.... like [bubblesound 600] instead of [bubblesound 2600] but the envelope is wrong somewhere.
[Cycle_Setup] is missing.

Sorry.. last bit posted here was a mistake on my part.

@BioMannequin I think the wav file you hear on the website was done with a patch similar to what was described in the following paragraph in the book. To me this sounds much closer to that.

Thank so much guys you're awesome!

It does sound a lot better when the arguments for the frequency are considerably lower, so it surprises me that in the book he's using such high argument values.

@weightless how did you get that zip to download? When I try to download the links on that site I just get a page of code

@BioMannequin I didn't I made it quickly from the pictures in the book. Although if you right click the links in the website > download linked file you can get those as pd files (otherwise just copy the code, paste in a text editor and save with the extension *.pd).
I kinda wish I thought of that sooner before making it from scratch! But it was just an approximation, if you get all of the patches on the website I'm sure you're going to get the real deal and can study them better than with just the book.

Ah thanks I've given that a go. Sadly Some things are missing, and bubbles2 doesn't want to load its abstractions even though they're all there. I was hoping I would be able to get the original and test it against what I'd put together myself

@BioMannequin Here is a zip of the ones I've been able to download. If I open the dripfactory.pd file, I get it to sound with no errors.

Wow legend thanks so much!

So in bubbles2 the arguments are 240, 250 etc instead of 2400, 2500 as it say s in the book, so maybe this is a typo? Because they sound much more like bubbles in this patch.

Although he does say "to have bubbles at different pitches we scale the pitch envelope by the first abtraction argument; typically this will be between 1khz and 3khz.

Weird
