qjackctl

Hi, I know that this is a linux forum but I couldn't think where else to post this. I compiled qjackctl on OS X 10.6.8 and everything seems to be in order. The Server will start, and other applications will recognise that Jack is running, but after about a minute it stops and a popup window informs me that: "Could not connect to JACK server as client.- Overall operation failed. Please check the messages window for more info." Furthermore, the connections window does not give me a list of available clients. It is empty, even when jackrouter is selected as an output in another application.

I registered with my email address & user name but return email had no password ???
Tried everything ... no luck.
Ah! Whats going on?

Hi,
I have been trying to record from a Fender Mustang amp, thru its USB cable. I use Ubuntu Studio 12.04. The amp is recognized by the computer. I can record into Audacity and Sound Recorder, but I can't make it work under QJack into Ardour or Qtractor. The only way I can record is if I choose the Mustang amplifier as Interface in the setup menu, which gives me no output (The amp is not like a two-way card, it only outputs the signal). Anything else (choose usb audio or Mustang Amp as Input) fails.
If anyone has ever had to deal with issues like this, please let me know.

Whenever I run hydrogen or lmms through jack I get distorted sound and a strange laser sound (like you would make as a kid) when the midi releases... I don't really know where ti begin. it did this with ubuntu 12.4 and mint 14

Hi, Newbie here. I have some questions regarding Qjackctl on Mac OSX (10.6.8) but first a little back story to set the table. Go to "THE MEAT OF IT:" below to skip the background.

My use for Qjackctl is with a virtual pipe organ program called jOrgan. It has a built in Fluidsynth extension that allows me to set up multiple FS instances each containing selected ranks of pipes. I had been using it sucessfully under Lubuntu on a Power PC laptop (PowerBook) but one memory slot died and so my brother sent me his old Intel (i5) MacbookPro with Snow Leopard installed.

Hi!

Problem:
Using QjackCtl, Audacity, and Skype, I can record the caller OR myself, but not both. (And I apologize for cross postings, but I've been trying to solve this for over a month and am getting desperate.)

Options:
No, I do not want to use a third party specific Skype call recorder.

Equipment / Hardware / Software:
Dynamic microphone
Firewire mixer
ASUS P5QC motherboard with onboard Realtek ALC 1200, 8-Channel High-Def Audio
Ubuntu Studio 13.04
Skype 4.1
Audacity 2.0.3
QjackCtl 0.3.9
PulseAudio Volume Control

Qjackctl Version: 0.3.10
a2jmidid Version 8
jack 1.99

Hallo Rui

It's one of those days, starting jackd using Qjackctl
- with midi-driver set to none (xseq and yraw do not enable external hardware ports and conflict with a2jmidid)
- and using the post start option "a2j start &"

The external hardware midi ports are disabled..!

This use to work and the external midi ports on device UM-1S used to show up in jack-midi but not anymore.

Any ideas?

With best regards, Simon

Hello RNC,

first of all I'd like to thank you for creating the probably most powerful audio routing tool
for the Linux platform. I'm using Jack and QJackCtl for a couple of weeks now and I'm quite
happy with it, since it finally allows me to use my firewire audio interface in Linux (in combination
with the FFADO drivers). Nevertheless I discovered a weird thing which I thought I should tell you
and this community.

Hi! I get a problem qjack's software! I bought this Usb'soundcard and I get 42 mm of latency to playing very well! When i try to get fewer latency, xruns running! How can I get better performance??? Pleaseee helppp meeee!!!!

Hello!

I just discovered this GUI and it looks like it could make life easier for me -- I've been using JackPilot with the latest Jack OS X version up to now.

I installed qjackctl, corrected the server routing (as mentioned in another post here), specified "core audio," sample rate, etc., and the server started up fine. The only thing is: in the Connections window's MIDI section, I get no clients/ports. In JackPilot, I get two ins and outs for my external sound card, two each for Max/Msp, and one each for the looping software that I use.
