Re: [PD] converting incoming audio/voltages into CV for Eurorack modules

[Simon Iten]

are you aware that you can increase the pwm frequency considerably? still less 
for 9 10 11 but far higher then by default for all pwm pins.

Re: [PD] converting incoming audio/voltages into CV for Eurorack modules

[Christof Ressi]

I'm right now controlling an analog synth via Pd :-). I'm just using an arduino 
- works well. It depends how many CV sources you wanna have, though. Generating 
trigger signals (e.g. for envelope generators) is really easy because you can 
directly use the digital outs. CV for modulation is a bit more tricky because 
you have to smooth the PWM outputs of the arduino with low pass filters. I 
found that using two RC circuits in series (with C = 1 microFarad and R = 3,3 
kOhm) works decently for pins 5 and 6 on the Arduino Uno (pins 9, 10, 11 have a 
lower PWM frequency and therefore might need a lower cutoff frequency). I'm 
thinking about trying out some multichannel DACs with 10 or 12 bit because PWM 
on the arduino is only 8 bit. DACs also operate at a much higher frequency so 
smoothing would be much easier.

Ahh cool, yeah, I saw that page but only quickly scanned and found no info

Howdy all,

I'm pleased to announce that the PdParty BETA has started!

After almost two months of work, there have been quite a number of improvements 
and I feel the app is now close to version 1.0 status.

I just need your help to find bugs, suggest improvements, and create demo 
scenes.

How this works

1. Send me your name & email*

2. I add you to the tester list

3. You should receive a notification email

4. Download the free TestFlight app form the App Store

5. Open TestFlight and install the latest PdParty build

*Those of you who participated in the alpha testing should already have 
received an email.

Happy Patching!

For similar reasons I was looking for a way to check the existence of a
file without causing an error message. I came up with this:

https://github.com/reduzent/netpd/blob/master/includes/netpd-if-file.pd

It uses [readdir] from moocow and [getdir] from ggee. Though quite
kludgey, it was the only way I was able to achieve that. If someone
knows of a better way (even if it uses an external), please let us know.

[PD] Using an external from patch directory -- readanysf~

[Samuel Burt]

Readanysf~ comes with a bunch of dynamic libraries (on Mac) and every other
version has its own set of things it needs. Does this mean it can't be
incorporated into deken?

>From what I understand, you can drop externals into a patch directory so
its easy to transfer to someone else who might not have that external
installed. Is this wrong? It isn't working with readanysf~? Currently, I'm
using OS 10.9.5, Pd Pd 0.45.4 and readanysf~.pd_darwin from 11/3/11(?!).

Is there a better way for reading back soundfiles with variable speed
playback from hard disk, now? or did I miss a more recent version of
[readanysf~]?

Thanks for the advice.

Re: [PD] Pd vanilla zverbose SSE, missing comments

[Samuel Burt]

IOhannes,

Thanks for the help. [abs~], an object I use frequently, was causing the
problem. Every time I used "Save" in Pd, it would trigger zverbose, six
times. I found six instances of [abs~] and replaced them with [expr~
abs($v1)] which did the trick!

I did not have any flags when loading Pd. I also needed level 2 logs to see
the errors I wanted to track.

Fred Jan Kraan,

Thank you for reminding me about Comment. I used that instead of comment
when I needed to control line returns, which it looks like I can do now
with vanilla comment.
