So I finally made recording working using jackd and ardour2 but there is
constant clicking, at rate maybe 1 or 2 clicks per second.
Any ideas how to troubleshoot this? Not sure if it's device problem, not
enough CPU or something else...
Here's my setup:
CPU: AMD E-250 1600MHz
RAM: 16GB
Ubuntu 13.04
Linux jojda 3.8.0-31-lowlatency #23-Ubuntu SMP PREEMPT Thu Sep 19
17:08:15 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
USB audio device: BOSS BR-80
Any comments/ideas? (please let me know if there's other relevant info I
can post)
thanks!

Just a note to say that as a result of a bug I put in Calf plug-ins
now support digit entry fields. This was due to some controls being
difficult to set accurately via the mouse. I have not rebuilt and
tested this yet.

A friend asked me if I had a Theramin sound. I figured, I could cheat with a sine wave or a deeply-filtered sawtooth maybe, but then I thought, hmm, what is a real Theramin wave anyway?
Google Images pumped me up nicely:
http://www.horst-theremin.com/images/_mid%20600%20Hz.jpg
Diagrams for waveforms of the original Lev Termen and RCA instruments, and the Moog and Big Briar Theramins, that I was able to find, also look similar to the above.
And, umm, that ain't no sine wave. It's got some strange bias, louder on the positive than the negative side, more rounded and sine-like on the negative side, and more like a sawtooth on the positive side. I'm told it's also non-linear and the waveform for the lower and higher notes look slightly different, but one thing at a time.
So I thought, well, maybe I could hack up a LADSPA oscillator plugin that does that weird waveform.
Looked at the SDK, and sure enough, in the sine.cpp file, there's an initialize_sine_table() that looks like the right place to put the wave. It's just a table of floats, looks like.
However, my DSP and maths skills stop right about there. I have no idea how to generate the points on that oddball waveform in such a way that they could be dumped into, say, g_pfSineTable.
Has anyone already done this? Anyone want to take a shot at it?

Hi all,
this weekend I need to do some synchronization work, and I was planning
to use Qtractor (though I've never used it before), but I thought I
might ask here, in case you think there are better tools to accomplish
this.
My setting is very simple: I have a two guitars piece and I have
recorded one of the parts myself. For the second guitar I have entered
the score with Rosegarden. But now I want to fine-tune the mixing of
both and I want to be able to synchronize the MIDI file to my playing.
With Rosegarden and the piano roll, I can easily stretch/move each of
the MIDI notes, but I didn't find an easy way to synchronize with my
audio wave (though I haven't used Rosegarden a lot, so perhaps I missed
something).
Ideally I would like to:
+ load in one program both the audio and the MIDI file
+ see the soundwave forms for both audio and MIDI plus the piano roll
for the MIDI file
+ if something is not synchronized properly (due to the nature of the
music, I can see it nicely by inspectint the soundwave), I would like
to stretch/move the MIDI notes in the piano roll and interactively see
how the soundwave changes, so that I can immediately see if the MIDI
and the audio are better synchronized.
Is there a tool where I can do that easily? Perhaps there is some other
procedure/tool that can help me with this?
Thanks for any suggestion,
--

trying to use Boss Micro BR-80 as USB soundcard with Jack but seems like
jack (qjackctl) does not recognize it.
My system: Ubuntu 13.04 with pretty much standard configuration (runs
pulseaudio, installed jackd2, pulseaudio-module-jack, qjackctl)
Have built in audio that I don't really plan to use with jack (or at
least not in initial setup where I am just trying to make something work):
00:01.1 Audio device: Advanced Micro Devices [AMD] nee ATI Wrestler HDMI
Audio [Radeon HD 6250/6310]
00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia
(Intel HDA) (rev 40)
Boss Micro BR-80 seems to be recognized properly (see below) but
qjackctl does not list it in Set under any of Interface, Input Device,
Output Device choices, I only see /dev/dsp, /dev/audio, plughw:0 and hw:0.
Any ideas why it does not work or how to troubleshoot it further?
When I plug BR-80 in I get (output of usb-devices):

I've had a Delta 66 PCI audio card for over a decade, and it's always
sounded great. I recently had to transfer it to a new PC with a fresh
install of Fedora 17. Now, when I play anything using any pulseaudio
client, I get a strange digital noise (sort of like static, but almost like
aliasing too).
This does NOT happen when running jack, as far as I can tell.
Aside from disabling or uninstalling pulseaudio, is there anything else I
can do? Does anyone else have this problem?
As falling leaves drift by the window, and without any further ado:
Qtractor 0.5.11 (lima oscar) is now released!
Soon we'll hear a new winter's song. This code-naming series, which
started on a sunny summer day two years ago as TYOQA, is now converging
to an end. It will be no surprise for some that today's release precedes
the very last one on that series. So let's get those autumn leaves
falling and grab them while they're crispy red and gold ;)
Release highlights:
* Extended automation curve editing (NEW)
* Extended clip selection (NEW)
* LV2 UI resize feature support (NEW)
* Aux-sends to audio buses (FIX)
* MIDI editor overlapped event velocity/value (FIX)
* Accidental export muting and/or freezing (FIX)

Change-log:
- Adding a track now inserts it after the current one, if any; one can
also drag and move a track below the last one in the track list (main
view left pane).
- Extended Edit/Select Mode/Automation: multi-selection mode, cut, copy,
paste and delete of current track's automation curve nodes, now reached
implementation ready status.
- Another old silent bug bites the dust: changing track names were
dropping any track gain/volume and panning automation curves when saving
the session.
- A primeval processing bug has been sorted out: aux-sends to audio
output buses that just appear to be after the input bus where they're
inserted were being left muted and silent (on a ticket follow-up by
Holger Marzen, thanks).
- Fixed a sure crash bug exposed when processing of aux-send plugins
when inserted too early on audio input buses chain (after a ticket
report by Holger Marzen, thanks).
- Allow the build system to include an user specified CFLAGS (patch by
Cristian Morales Vega, thanks).
- Shift/Ctrl keyboard modifiers now set to extend current clip selection
while in main track view's Edit/Select Mode/Range, Rectangle modes.
- Main Edit/Select Mode/Automation icon retouched to look a bit more
obvious and intuitive, hopefully ;)
- Allow to change the velocities/values of the current selected events
which have the exact same onset times and hide beyhond each other on the
MIDI clip editor's pane below the main view piano-roll (ie. the one that
represents MIDI event values as a bar chart).
- Fixed some problematic playback/export muting and annoying cleanup
freezing, due on audio tracks with too many clips eg. more than hundred
clip splits (hopefully fixes an issue reported by Louigi Verona, thanks).
- LV2 UI resize feature support/control added.
- Fixed dedicated MIDI control and MIDI metronome port connection
restore conflict (thanks to jhammen catch & patch:).
- New user preference option added: reverse middle-button role to
Shift/Ctrl keyboard state, in special regard to edit-head/tail vs.
play-head positioning while on the main track and MIDI clip editor (aka.
piano-roll) views.

Hi,
Trying out Lives video/VJ tool.
I want to make video art for a live gig. Its mostly making a clip from a
picture and adding some effects to it, realtime effects and normal
effects too. Im not planning to add effects live, but I want to apply
the live realtime effects before the show. Im working in the clip
editor. I will use Lives to switch to the next clip for the next song.
What is a right format, size and resolution to export to, so I can use
the clips during the gig? Audio is not needed.
Tips for this workflow is welcome!
Thanks in advance,
\r
