Hi,
I've got a strange behaviour with my midi controller and/or freebob/ffado.
I made a pure data patch, with a midi learn function. So I can control
everything with my midi controller.
When I use jack with Freebob or ffado (I tested both) and a Presonus
Firebox, I got cracking sounds every time I move faders, pots from my Midi
Controler.
When I use jack with alsa and a poor usb berhinger UCA202 it works perfectly
: no cracking sounds
I am running Gentoo, with a rt kernel. I configured the rtirq script.
I tested it on a opensuse with rt kernel too, and it does the same.
Could someone test my patch and tell me if he got cracks ? with firewire ?
with alsa ?
You will need at least pd-0.40 or more.
Some externals, they are not necessary to hear sounds (bbogart (for popup),
sigpack~, zexy, iemlib).
The patch contain
* 3 live loopers with effects
* Master to set tempo, general volume, general pitch, and rooting + a
preset/bank system.
* a sub-patch with a DrumStation
* a sub-patch with a small synth (TriOsc)
To test rapidly you just have to click on the load bank button (on the
bottom-left corner), and you should hear sounds from the TriOsc synth
Then you can assign control clicking the green led under each control. The
red one is to forget the assignement.
here is the patch : http://mysthr.free.fr/Documents/LiverLooper-0.6.tar
Thank you very much !
kind regards,
Mysth-R

Is your midi controller attached to the Presonus box or is it a USB midi
controller?
What settings do you use for jackd?

try increasing the priority of jackd to 65:
/usr/bin/jackd -R -P65 -dfirewire -r48000 -p256 -n3
I suspect that it has something to do with the kernel layer since it's
present in both freebob and ffado.

What, in your mind, could be the problem ? software ? hardware ?
on my gentoo I have compiled my own kernel (2.6.25.4-rt5). But on the open

This is incredible !!
well, after some days googling, compiling kernel and tweaking my laptop
(set_rlimit, setpci latency_timer, rtirq, etc...) I got the same results.
But testing again and again I found that I got crackling sounds with my
firewire sound card (using freebob or ffado), and also with my usb sound
card. Tests were :
frame/period : 256 ; Period/buffer : 3 ==> bad !
Frame/period : 512 ; Period/buffer : 3 ==> bad !
Frame/period : 1024 ; Period/buffer : 3 ==> ok but with an unacceptable
latency : 64 ms...
finally I thought that it was a pd issue, and in some kind of aspect it was.
(due to too much midi messages at the same time).
But when I tried my patch with :
frame/period : 64 ; Period/buffer : 3 ==> it was ok !!!
So strange ?! Why does it works with a latency of 4ms or 64ms and does not
work for other settings ?
Well I am happy because I used to play live... so a 4ms latency is really
good for me. But I would like to understand ?!

Yes I got a ricoh but I had too much issues with it. Now I use an
ExpressCard with firewire extension, and it has a Texas Instrument chip (see
the two last line of the lspci result).
Perhpas due to a rate transfer of the Express Card ....

Hi,
I've got a strange behaviour with my midi controller and/or
freebob/ffado.
I made a pure data patch, with a midi learn function. So
I can
control everything with my midi controller.
When I use jack with Freebob or ffado (I tested both) and a
Presonus Firebox, I got cracking sounds every time I move
faders, pots from my Midi Controler.
When I use jack with alsa and a poor usb berhinger UCA202
it
works perfectly : no cracking sounds
Is your midi controller attached to the Presonus box or is it
a USB
midi controller?
I tried with USB and directly attached to the Presonus. My
controller is a Korg microKontrol, but I tried with another
controller too (an EMU I think)
I also tried with Jackd and Jackdmp , cause I am on Gentoo 64bits.
Strange...
What settings do you use for jackd?
My settings are :
/usr/bin/jackd -R -dfirewire -r48000 -p256 -n3
does it happen with higher buffer sizes too?
try increasing the priority of jackd to 65:
/usr/bin/jackd -R -P65 -dfirewire -r48000 -p256 -n3
I suspect that it has something to do with the kernel layer since
it's present in both freebob and ffado.
Ok I have made some tests
First test :
priority : 65
frame/period : 4096
Test OK !! :)
Second test :
Priority : 65
Frame/period : 512
It cracks !
Last test :
Priority : 65
Frame / period : 1024
Test OK !!
A friend of mine just tell me that my pd patch works find with his
config, and freebob : no cracks !
What, in your mind, could be the problem ? software ? hardware ?
You seem to be running a Ricoh 1394 chipset, that can be a problem. I
think you're experiencing a hardware issue.
Also, for me the pd patch crackles without doing anything, but then again
I don't know how to use pd properly.
You can try to run pd with :
$ pd -rt -jack -alsamidi
Greets,
Pieter
