Hi all,

I found a Csound patch synthesizing sounds for a handpan on this page and it sounds great.
I then wanted to interface it with my MIDI controller so that rather than learning Csound from scratch, I've embedded the CSD synth into a Pd patch using the [csound6~] external. Works great.
The next steps however were to use such Pd patch on my smartphone via MobMuPlat, or in a DAW using plugdata (my attempt at generating a VST with Cabbage shows very poor CPU performance), however both are based on libpd and don't support [csound6~].

So I've taken the approach of reproducing the csound patch in vanilla Pd, which was very instructive. I've followed the same variable, function names and logic, read a lot of documentation, and came up with the patch attached.
handpan_comparison_csd_pd.zip

However, the sound is not quite the same. There is a huge lot of high frequencies in the Pd version, which I couldn't quite eliminate even using up to 10 successive [lop~ 900] (I've left only one in the patch for now), but more generally I can't figure which differences between the csound patch and the patch may have this effect. Note that I am neither an expert in Csound or in filters - in particular I don't quite trust the Butterworth3 filter I hacked together - can I even realistically expect that the same algorithmic logic in Csound and Pd would produce the exact same sound?

So I'm now asking here for help, in case some experts may find the time to review what I've done in Pd and compare it with the Csound patch, and may be able to suggest improvements. I know it is quite tedious work but I am hopeful Thanks in advance to anyone who gives it a try!

(Note that this patch was embedded in a more complicated one including interfacing with the midi controller, definition of various scales, debugging/monitoring etc., which I've removed before sharing it here, but I may have forgotten some bits here and there, let me know if it complicates the review!)

@4poksy My largest patch is 230k and is a single patch which uses no abstractions* or even audio rate objects and it can eat every bit of ram and cpu my computer can give it without much fuss. I can probably write a small patch with just a handful of objects which can eat my cpu and ram. Knowing the resource use of individual objects will not be very useful, how you use them is fairly important and will effect resource usage, GUI and symbols can drag pd down even if the rest of the patch is fairly small. Your time would probably be better spent improving your patching skills so you can make more efficient use of pd, a slight change in methodology can have large effects on resource use. The first version of my 230k patch was only 84k and considerably less capable but hit the wall much more easily than my current version, difference is I learned about how pd worked and how to work with it, as a result my patches have gotten more efficient.

*Technically it uses one abstraction but it is a small abstraction of just a dozen objects which is dynamically created as needed, the patch can eat my computers resources with just one instance of the abstraction or run perfectly fine with 100 instances depending on what I ask of the patch.

@4poksy 64 samples cannot be modified for links between patches and sub-patches.... [inlet~] etc. ...nor for final input and output.... [dac~] etc.
It can be modified within a patch or sub patch using [block~].

Patches are very small on disk and in memory..... your os will tell you the size.... they just contain text.
The biggest patch (hundreds of patches running together) that I have ever built uses less than 100K on disk. The objects you call are loaded to and run within the Pd binary as you open the patch.
Pd itself uses about 8.5K of ram with no patches open, and the gui program "wish" just over 15K (in windows 7).
When that massive 100K patch is running Pd expands to use 76K of ram and wish reduces its space to use 12K.
Arrays are the size you choose, and can be large if you are storing audio..

Pd can (sort of) report its cpu load....... dsp~.zip

For more on what actually happens "under the hood"..... http://puredata.info/docs/manuals/pd/x2.htm
.... but that document is also in your Pd installation in the "doc" folder........ /doc/1.manual/x2.htm

Pd builds a "super-patch" from all the patches you open, and the audio thread is rebuilt as you change or add objects and patches. That means that it is always running, but there is no buffer between patches unless you make a mistake..... see the doc above...
You can also use [block~] or [switch~] to turn off audio processing within individual patches and sub-patches...... useful for saving cpu load when switching between effects.

Welcome to the forum...!!
David.

P.S I am usually wrong about something and others will tell you where.

Hi,

I am trying to get ofelia to run on a couple of rpi. Right now I am trying a rpi 3B+ running https://blokas.io/patchbox-os/

I run ofeila with the ofelia-fast-prototyping abs on my mac successfully.

Following install instructions here https://github.com/cuinjune/Ofelia
after running
sudo ./install_dependencies.sh
it ends like this:

gstreamer1.0-omx is already the newest version (1.0.0.1-0+rpi12+jessiepmg).
The following package was automatically installed and is no longer required:

Thankful for help!

Hi all!

I had some time during vacations and I wanted to try running Miller's espd version. Here's a small tutorial.

The development board I bought: ESP32-LyraT > Mouser | Aliexpress

INSTALL ESP-IDF (IoT development framework)

mkdir ~/esp && cd ~/esp
git clone -b v4.4.2 --recursive https://github.com/espressif/esp-idf.git
cd esp-idf
./install.sh esp32

INSTALL ESP-ADF (audio development kit)

cd ~/esp && git clone --recursive https://github.com/espressif/esp-adf.git

SETUP ENV VAR

export ADF_PATH=~/esp/esp-adf && . ~/esp/esp-idf/export.sh

ESPD

download espd: http://msp.ucsd.edu/ideas/espd/

cd espd
git clone https://github.com/pure-data/pure-data.git pd
cd pd
git checkout 05bf346fa32510fd191fe77de24b3ea1c481f5ff
git apply ../patches/*.patch

Edit main/espd.h put your wifi credentials and the IP of the computer that will control espd:
#define CONFIG_ESP_WIFI_SSID "..."
#define CONFIG_ESP_WIFI_PASSWORD "..."
#define CONFIG_ESP_WIFI_SENDADDR "...."

mv sdkconfig.lyrat sdkconfig

idf.py build
idf.py -p /dev/ttyUSB0 flash (hold boot and then press reset on lyrat)
idf.py -p /dev/ttyUSB0 monitor (Ctrl+] to exit)

HOST

• open pd installed on (SENDADDR)
• open test-patch/host-patch.pd

If connected this message (ESPD: sendtcp: waiting for socket) will stop and you will see the mac address in the host patch.

1- click on [send pf begin-new poodle .<
2- click on [line 0, auto< to send the defined patch (esp-patch.pd)
3 - click [send pd end-new<

4 - connect headphone, play with [send f 440< and [send f 660<

Custom patch:

• Use mono [dac~ 1] only
• Add this to your patch:
  
• in host-patch.pd change [read your-patch< -> [text define patch] redo step 1 to 3
  

TODO

Would love to play more with the code, right now I am not able to load complex vanilla patch. Also using the AUX (or built-in microphone) would be awesome (but I'm wondering about the round-trip latency (would it be under 15ms)).

@dkeller Even working with some of the Jazz "greats".... or should that be "grates"?..... I have met almost none that can truly improvise. A huge learned repertoire of perfect riffs seems to inhibit their ability to really innovate.
This could perhaps be a great learning tool.

Pd looks in its standard directory (Pd/bin) and the externals folder (Pd/extra) and the patch folder as it opens a patch. You can add other paths to search in Pd preferences.
If you put an external or an abstraction (like [once]... abstraction because just a patch... not compiled) in the same folder as the patch it will work just with that patch.
If you put it in a sub-folder then in the patch you will have to tell Pd where to look..... so [subfolder/once] in your patch instead of [once]....... or declare the path in the patch by placing an object [declare -path subfolder] in the patch.
If you want to use it everywhere then dump it in the extra folder...... which means you can put it in every patch..... BUT..... when you share the patch you will need to remember to bundle it or the recipient will not be able to create the object.
David.

@Worik Not sure what you are looking for.....
If you want to open a patch from the command line you can open Pd and a patch with a batch file...... in windows it would look something like this....

"C:\Program Files (x86)\pd\bin\pd.com" -path C:\Users\David\Desktop\PDMusic\Minx -path C:\Program_Files_(x86)\pd\extra\readanysf~\ -r 44100 -asio -nomidi -audioindev 20 -audiooutdev 15 -inchannels 32 -outchannels 22 -audiobuf 2 -blocksize 64 -callback -nosleep -open Minx_Run.pd
exit`

which on my system opens Minx_run.Pd and tells Pd where to find it........ \PdMusic\Minx
It also sets a load of command line switches...... to set up audio for this very specific instance (useful!).
There will be similar methods in other os's.

When you want to close the patch (and Pd) you kill the Dos window that the batch file created.

Messages can be sent to Pd to close a specific patch..... but another patch will have to be open (probably the one receiving the message) or Pd will terminate.
It can be done from within the patch but its complicated........ https://forum.pdpatchrepo.info/topic/11710/closing-patches-without-pd-crashing-hopefully-in-an-elegant-way ...... and not easy.

If you want to keep Pd open and control from another program........ then as @seb-harmonik.ar describes........ but the menuclose message might crash Pd if another patch (any patch) is not open........ https://forum.pdpatchrepo.info/topic/4063/close-patch-window-command-object
Anyway, it is cleaner to use a second patch to receive your messages and close the desired patch.
David.

@ddw_music Sending to {value] is really what got me, they were getting their bangs before their new values arrived. I I had just copied part of the patch into a sub-patch to clean things up, this moved that bit to the end of the patch and caused the problems. If I had realized what had happened earlier I would have just moved the sub-patch in a text editor but I tried to fix things in pd and made it a hopeless mess. I have now adopted using sub-patches to structure order creation and using wires between them for all timing critical information, this means I can edit the subpatch and keep everything in that sub-patch in the proper place in the chain regardless of my editing. I knew about the order creation for sends and receives and the patch worked perfectly before that edit which changed nothing about the physical patch, I just did not understand the long term consequences and what would happen when I change things a year down the line. Wasted a few hours and ended up redoing the patch from the ground up, but it is greatly improved and more robust regarding minor edits years down the line breaking it and even if they do I will only have to deal with a small subpatch as I no longer have all the sends to communicate between the sub-patches. Lesson learned.

Hey, I'm trying to get purr-data to work on my fresh Manjaro XFCE install, but it does not work. Any help is greatly appreciated!

Hey everyone
I've been working on a fairly elaborate sequencer patch in Puredata Vanilla version 0.52. I'm using just vanilla objects which have all been available in Puredata for some time.

I noticed when I open this patch in "Purr Data" or in older versions of Vanilla Puredata, (like 0.49), all the objects load correctly, but a lot of the patching is wrong. Specifically in sub-patches, the patching is just...... all over the place with cords going everywhere and not at all how it was patched when I made things.

I'm interested in making sequencers in Puredata that can be used on platforms like Bela or the Organelle. Those types of things usually use older versions of Pd. I expected that, because .pd files are human readable text files, there would be backwards compatibility, but I guess this was a faulty assumption?

I'm curious:
Is Vanilla Puredata generally not backwards compatible with older versions? Or is this a bug? Is there any easy way I could correct the patching in my patch so that it'll open in older versions of Puredata without having to re-patch everything? Or should I just stick to older versions of Puredata for this type of work going forward?

thanks
