Announcing the latest release of the Phase Harmonic Advanced Synthesis
EXperiment (first release featuring a GUI), available for download (source
tarball and FC6 RPMs) at:
http://sysex.net/phasex/
PHASEX is an experimental softsynth for Linux/ALSA/JACK systems with a
good mix of standard and experimental features. Here's a quick
overview of what PHASEX offers:
* GTK GUI: Every paramater is available through the GUI, with parameter
names right-clickable for on-the-fly MIDI controller mapping and
middle-clickable for parameter help.
* 4 Osc / 4 LFO: Oscs and LFOs support multiple sources: MIDI key, tempo,
envelopes, and inputs, all with selectable unipolar/bipolar scaling.
Wavetable includes the basic wave shapes, both bandlimited and
non-bandlimited. Per-osc and per-LFO transpose, pitchbend, and init
phase.
* Modulations: Full AM, FM, and PM (in this case, modulation of phase
offset between left and right channels) routing with per-osc controls.
Each osc can be modulated by any osc or LFO for AM, FM, of PM. Wave
select modulation by LFO modulators is alsa available.
* Filter: Modified Chamberlin filter with LP, HP, BP, BS, LP+BP, HP+BP,
LP+HP, and BS+BP modes, distortion and retro (clean) types, keyfollow
modes, ADSR envelope, and LFO cutoff modulation.
* ADSR Envelope: Standard ADSR envelopes for amplifier and filter.
* Chorus: Stereo crossover chorus with builtin phaser.
* Delay: Stereo crossover delay with LFO modulation capability.
* Key Modes: Mono smooth, mono retrigger, mono multikey (round-robin
mapping of MIDI keys to individual oscs), and full poly modes are
available.
* Input Processing: Inputs may be routed to any combination of oscs and
LFOs. Input boost allows weaker sources to be brought up to level of
oscs. Envelope follower applies input envelope to output.
* Sampling Modes: Supports undersampling and oversampling, giving control
over the ever present quality vs. CPU tradeoff.
Since this is the first public release of PHASEX with a GUI, feedback is
highly encouraged. The project goal is to provide a synthesizer to
experimental and professional musicians alike that is as easy and
enjoyable to use as it is powerful. The next batch of new parameters and
features will be a result of feedback from the community, so please, don't
be shy.
Cheers!

Hi, it's good to see a new soft synth on the block! PHASEX caught my
interest also because it has a lot of features that my own Snarl synth
project aims to implement (http://gna.org/projects/snarl).
I'll give it a spin later this evening and maybe comment on the sounds.
I'm happy with the collection of patches it ships with, saves me time. :)
I already did a test build (./configure --prefix=/usr
--enable-arch=nocona && make && make install) and noticed a few
anomalies. First I had to insert '#define PHASEX_DIR
"/usr/share/phasex"' in src/phasex.c because of this build error:
make[2]: Entering directory `/home/juuso/tmp/phasex-0.10.0/src'

make[2]: *** [phasex.o] Error 1
Apparently something in ./configure isn't working properly. Also, the
program seems to segfault easily when everything isn't in order. This
happens when snd-seq-midi isn't loaded:
Unhandled ALSA MIDI error. Exiting...
Segmentation fault
And this I got when I tried running phasex before I actually had jackd
installed:
sh: jackd: command not found
Status = 0x 1
Unable to open JACK client.
Segmentation fault

Fist I'd like to say thank you for this app. Looks great, sounds great
and is GPL'd.
I'm getting this crash on exit

What is right way to enable debuging? I dont see --enable-debug to
configure and it seems to ignore CFLAGS. I modified generated Makefiles
to use -g -O0 to get the backtrace.
Have you considered using widgets from PHAT? I beleive there is no
difference between knobs you use and phatknobs. If there are
improvements chances are they shoud got in PHAT version too.
The thing I'm missing mostly now is JACK MIDI support.

Really nice synth! Thanks.

Very nice sounds. Since you asked for feedback, here is some:
* the whole program crashes for me when I pull down the File or Patch
menus or try to close the window, with lots of Gtk error messages
about invalid style objects. If I change line 241 in gtkknob.c from
widget->style = gtk_style_attach(widget->parent->style, widget->window);
to
widget->style = gtk_style_attach(widget->style, widget->window);
it doesn't crash any more. Other behaviour seems to be identical.
* support for JACK MIDI or having the whole synth loadable as a LV2 or
DSSI plugin would be very nice for using sample-synced MIDI
* support for LASH or having the whole synth loadable as a LV2 or DSSI
plugin would be very nice for session saving - the way it is now you'd
have to save and load the current patch separately from the rest of
the session (sequencer state, other synths etc)

Hrm. There aren't any pull-down menus in nekobee (where the knob code
seems to be from), so I've never seen this happen. I'll roll that into

OK, I tried out the sounds like I promised. I have to say Phasex
produces by far the crispiest basses I've heard in any Linux soft synth!
Thanks for writing such a great instrument.
Unfortunately I also experienced one zombification and one total
segafault nosedive. I wish I could say I backtraced them, but I didn't.
Both bugs happened while playing a note; the zombification seemed to
come out of nowhere, and the segfault happened when I turned the delay
time knob to the far right with the mouse.
I hope the stability issues are resolved soon, because I'm looking
forward to doing some sequencing with Phasex without having to fear
losing data.

PS: I added Phasex to Source Mage GNU/Linux's package repository.
PPS: It'd be great if you could come and hang out at
irc://freenode.org/#lad.
