Hi there,
I'm playing with all the new toys you brought me and have quite some
fun. Just two or three years ago I knew everything out there, now
there are a whole lot of new things to play with.
I have a few questions though.
Is there any new midi sequencer? I know the traditional ones, seq24,
rosegarden, muse, qtractor and so on and briefly tried ardour3 as well
as luppp but could not make heads or tails of it yet. What do you use?
Any idea what happened to the calf stuff? I tried them from git but
the, as far as I remember, wonderful wavetable synth crashes the hosts.
There seems to be a fork of the calf instruments and plugins by falktx
but the wavetable synth and the GUIs seem to be missing.
My goal at the moment is to create a single, simple and probably quite
horrible song electronic music song. That's why I'm looking for a nice
sequencer and some instruments.
Regards,
Philipp

Regarding to this issues I replaced calf monosynth with synthv1. Some
time ago, perhaps one or two years, Rui released some new instruments,
synthv1 is the first I'm testing at the moment, but it seems to be
hugely satisfying. I didn't compare it with real synth, but at least for
a virtual synth it sounds nice.

Thaks Ralf,
the monosynth is nice in its own right and it still works. I think
I liked the wavetable synth better.
I briefly tried fabla which is also a wavetable synth but couldn't
quite get sounds that I liked out of it, some of its presets do better
though, so I probably just haven't figured out how to do it yet. I also
used to like phasex, but since the recent thread about it I'm a bit
scared to use it.
I guess I'll give non-sequencer another go, it looks a bit different
from what I remember. First I'll have to make myself familiar with NSM
though, back and the day there was only lash and ladish.
I'll try to not get caught up in too many technical details this time
around and make some sound instead.
Regards,
Philipp

I'm also scared. I claimed that I didn't notice this issue, but later I
remembered there were issues. I don't know if it were dc offsets.

Simply removes the DC (0 Hz) component from an audio signal, uses a high

Thanks Fons, much appreciated. It seems the original author didn't
touch the code in more than 1 1/2 years, so the bug report would likely
had no effect.

The original author seems to have been missing in action for quite some
time, though it's not the first time. He disappeared for a long time before
the last exciting, though flawed update, which led to a github fork at the
time. When he re-appeared to much fanfare he communicated great intent to
maintain Phasex, and then promptly disappeared again. Attempts by multiple
people to contact the author through numerous channels have been
unsuccessful so far as I know.
It would be a shame for Phasex to go by the wayside, as it really is a very
cool sounding synth, problems aside.

Actually it's the only virtual synth that IMO relatively often can
compare with some CEM (Curtis) based analog synth-sounds. The "Moog's
wandering pitch tracking" sounds sometimes exceed even CEM (Curtis)
synth, however, even some Moog synth used CEM (Curtis). Dave Smith
likely is the Steve Wozniak of vintage analog synth maintaining. It's a
pity that he nowadays has got the monopoly for good synth chips :(. JFTR
I don't know how to repair my digital age TG33 either ;) ... chips die
out.

The following patches seem to fix the problem. They remove the
(inoperative) per patch DC blocker and add one per voice, just
after the oscillators. More testing may be required.

Perhaps a typo? You should post the output. For what version are Fon's
patches and what version did you use? I'm to lazy to test it today, I'll
continue within the next two days.
Philipp are you on Arch Linux too?
IIRC Fons' compiles much software, instead of using PKGBUILDS. I use
much official and many AUR PKGBUILDS, very seldom I build software on my
own.
There's some latitude. We might have different source codes installed.

Hi,
please consider to add the patches, to avoid DC offsets.

Thanks Ralf,
I tried it and it seems that the patch applied properly.
I can't say much about the DC-offset problem yet, but phasex definitely
needs more fixing. I can reliably crash phasex by attempting to switch
from jack autoconnect to manual connections. With autoconnect enabled
it is impossible to do any manual connections to and from phasex. It is
possible to change that manually in the config file tough.
A somewhat related question: What is the currently recommended way to
bridge between alsa and jack midi? For now I start jack with '-X
alsa_midi', which seems to work, at least in one direction.
Regards,
Philipp

I don't know. It might be different for jack1 and jack2 and for
different releases.
For a current project, just interrupted by a cold, the script to restore
sessions uses this combination, jack2 1.9.10-1 "-Xalsarawmidi" and
"a2jmidid", assumed it still should be the best solution to minimize
MIDI jitter, when using external synths, while for the few bars I played
until now, I don't use external synths. If this shouldn't satisfy me,
then I would start searching the LAU and LAD archives.
Btw. yet the project only uses synth plugins and the bridge isn't
needed:

The strange thing is that there is a DC blocker in the code,
but it's not enabled (at least not in the AUR package), and
it's in the wrong place. It sort of works but it far from ideal.
I'm currently patching the code to have a DC blocker in each
voice and right after the oscillators are mixed.
Sometimes I dislike you, but often you provide very useful things :). My
apologies for my weaknesses and thank your for your effort :).
Fixing phasex is very cool! IMO some sounds can compare with CEM
(Curtis) based analog synth.
The only
real solution is to remove the DC offset at the output
of the oscillators, before it enters the rest of the audio chain.
Thank you Fons,
I reported the issue.

I've got no doubts anymore, that I experienced the DC offsets too.

I briefly tried fabla which is also a wavetable synth

quite get sounds that I liked out of it, some of its presets do better
though, so I probably just haven't figured out how to do it yet.
I presume you mean Sorcer not Fabla, http://www.openavproductions.com/sorcer ?
Sorcer is aimed at "dubstep basslines", and is not a general purpose synth.
Good news is that OpenAV is working on a multi-purpose wavetable synth, however
it is not yet ready for announcement. Development is ongoing and progressing,
but this is a very large and complex instrument, please be patient! For the
curious, there's some info about Ninja here:

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.
Hi there,
...
Is there any new midi sequencer?
If you're not averse to spending money, check out Bitwig. I like its
MIDI capabilities.
Best,

Luppp does not (at time of writing) support MIDI. There is ongoing
development in
this area too, but note this is not yet available or stable for testing.
the, as far as I remember, wonderful wavetable synth
crashes the hosts.
Full disclosure, last I checked, the wavetable synth had to be
compiled with
--build-experimental-plugins or similar flag. If those are built into distro
packages, its not the Calf devs fault..
There seems to be a fork of the calf instruments and
plugins by falktx
but the wavetable synth and the GUIs seem to be missing.
Re wavetable synth
missing: good. Re GUI's, I don't know.
My goal at the moment is to create a single, simple
and probably quite
horrible song electronic music song. That's why I'm looking for a nice
sequencer and some instruments.
I will advise QTractor, and some LV2 instruents. I
use Fabla for drum beats,
Sorcer for some dirty basslines, LMMS (exported to audio) for some strange
things, ZynAddSubFX for pads / bells / general, and various LinuxSampler /
QSynth patches for the rest. Its quite a toolset to get to grips with,
but it does work.
QTractor has good support for automation (although its a little
"hidden" in the UI at first,
its actually fine to work with once its learned how-to :)
