Hella Frank,
I'm not sure if your method is working. I want to design something like an general Comb filter, in which I can tap in and tap out the signal where I want.
So the problem is the feedback of the Comb filter: There is already some signal in the delay line and I want to add at certain points some different signal without breaking the delay line at this point.
Do you have another idea, or is yours a solution to my problem and I don't see?
Best, Sebastian Schlecht

Do you have an idea to implement this?
I don't think it's possible to directly write delayed signals into a delwrite~ without an additional delay. However as in Pd delwrite~ and delread~/vd~ are separate objects, why not write the signal into a single delwrite~ at the beginning and adjust your delread~s with growing delay times? E.g. like this:
[delwrite~ DEL 5000]
[0
| [s DELTIME][r DELTIME] | [delread~ DEL]
[r DELTIME] | [+ 50] | [delread~ DEL]
[r DELTIME] | [+ 100] | [delread~ DEL]
[r DELTIME] | [+ 150] | [delread~ DEL]
Ciao

"synaesthesia happy hour" is a 2 days workshop that will introduce you to data mapping and basic synaesthetic tricks to get you started making real-time audiovisual experiments based on incoming data taken from various sources. In this crash course we will focus on how a single source of information (for example data from a sensor, or a log file) can be used to both generate sounds and visual. After the workshop you will never see numbers the same! (your mileage may vary)
The workshop is targeted to beginners only, for artists and students who are curious about data mapping and want to get introduced to Pure Data (http://puredata.info/). We will run the software from the pure:dyne GNU/Linux distribution (http://puredyne.goto10.org).
More information: http://goto10.org/data-jam-workshop-synaesthesia-happy-hours/

This workshop is part of the pure:dyne for everyone project, a national project designed to make pure:dyne more accessible through special events with partnering media arts centres across the country. pure:dyne for everyone is possible with the support of the Creative Partnerships programme of Arts Council England.

one way to do this is to implement your own delay line using four [tabwrite~]s and a single [tabplay~] or [tabread4~]. you'd have to conceptually reverse things though, because rather than tape moving around in a loop and the heads staying still, as happens with an analog tape delay, you'd have the 'tape' staying still while the digital read and write 'heads' (the [tabwrite~] and [tabplay~]s or [tabread4~]s) moved around it. the only problem with this is that you can't change the record rate of a [tabwrite~].
hmm. [tabwrite4~] anyone? it should be possible.. just invert the interpolation equations...?

any chance for a 64 bit hardy release?
i guess it is as simple as donating a 64bit hardy machine to the build-farm :-)
i guess the main show-stopper is (was), that Pd itself has not become 64bit-able until Pd-0.41; since Pd-extended is only catching up with this version, it is natural that there have not been any 64bit versions
yet.

Mostly, it's a matter of having a 64-bit machine for the build farm. I currently don't have access to any 64-bit GNU/Linux machines.

In the Pure Data FLOSS Manual, there are a naming couple conventions that I'm still uncertain about using there:
- audio object vs [dataflow/message/non-audio/data/numeric] object
I like "message", I think that is pretty widely used. "dataflow", "data", and "numeric" are all not correct, so should be avoided IMHO. audio and message objects can have data, numeric data, and all are part of the dataflow.
- edit mode vs [play/perform/performance/non-edit] mode
I think in the Pd manual, it's called "run" mode, but that doesn't make sense since Pd is always running. I like "play" mode.

We've already discussed "Pd vs PD" here. Anybody wanna give these others a shot to make one canonical?
Hopefully this won't get to out of hand... ;-) best, D. -- derek holzer ::: http://www.umatic.nl :::

Hi,
I can't get this to happen... can you send the offending patch?
thanks M

hey,
on OSX, if i accidentally trigger an infinite loop situation with a readsf~, it eats up all Pd's filehandles; then when i try to save

error: filename.pd: Too many open files
it seems to me as if readsf~ isn't freeing the filehandle if its call to fopen fails.
