Hi everyone!
I have been using AlsaModularSynth for the past several years and I just
love the sound of its internal modules... But AlsaModularSynth is a bit old
looking, and it doesn't support LV2...
On the other hand, Ingen looks brilliant, but I have never been able to
recreate what I was able to do with AMS... I always had some weird issues to
set a simple VCO/VCA/VCF setup...
I see two solutions to that problem :
- integrate LV2 to AMS...
- extract the AMS internal modules and create LV2 plugins from them...
From the quick study I have done of the AMS source
code, that second
solution seems "quite simple" (as quite simple can be!),
but I have few
questions before I start on this quest :
- first of all, would porting the AMS modules to LV2 change the sound?
- is it actually possible to do it? Or did I miss something?
- what is the future of Ingen? Altough it has be around for a while, it is
never available in official repositories of Ubuntu for example... Is Ingen
more meant to be testing LV2 plugins or can it be uses as a proper modular
synth? I believe only Ingen and AMS have this modular way of creating
synthesis?
- hmm, anything else I should consider?
Thanks in advance for the help,
Aurélien

And the current 2.0.1 release seems to have a rather major
bug: ladspa modules seem to be always created in monophonic
mode, and their control ports get the sum of the values
for all voices. This makes no sense at all.

Indeed. To provide the simple high-level "modular synth" approach
comparable to AMS we need some new plugins...
- extract the AMS internal modules and create LV2
plugins from them...
++
- first of all, would porting the AMS modules to LV2
change the sound?
Nope.

something?
Yep.
- what is the future of Ingen? Altough it has be

it is never available in official repositories of Ubuntu for

It is currently unreleased, and has been for a very long time. I am
aware this situation is less than ideal :) It will be stable/released
at some point. My work on LV2 is pretty much a direct offshoot of
working on Ingen - if you want a powerful modular environment that uses
(almost) exclusively generic plugins, you first need a powerful enough
generic plugin interface. We're getting there. :)
The nice thing about generic plugins, though, is that porting e.g. the
AMS modules to LV2 benefits any program that uses LV2 plugins. Ingen
will some day fill that role (and more, being designed to go beyond the
VCO/VCA/VCF "modular synth" thing into Max/Pd like territory). I am, of
course, biased, but personally I think porting any valuable DSP bits
currently jailed within a single program to (LV2) plugins is one of the
best contributions to LAD that could be made right now.

as a user, I agree... and while we're at it, I'll mention that
rakarrack has some great effects coded in that would be nice to have in
LV2

Ok, so that's a great incentive to have a go at it then!
I just saw the LV2 Hello World in C++...
AMS internal modules are wrote in C++, without specific GUI...
All right, how hard can it be!
I'll let you know if I face any issues!

In meantime it wouldn't be bad to
have AMS with JackSession support (=
feature request) :)
Good luck!

Which are you referring to? Link?
Note that the C++ wrappers are an additional layer on top of the actual
LV2 API, but you can write to the actual LV2 C API with C++ as well.
See e.g. http://lv2plug.in/repo/trunk/plugins/eg-amp.lv2/ for a simple
example of a plugin using just the C API.
Good luck,

But I believe that's the same example as the one you pointed to below.

So you would advise to write them in C?
I'll have a look at the simpliest way from the AMS code (may be start
with one of the simple VCA or Noise module).
Good luck,
Thanks :)
