Was about to ask especially you about that until I solved this on my
own. But thanks a lot for your explanation.

First release of LV2 versions of the NJL ladspa plugins by Nick Lamb.
This is a preliminary release, LV2 URIs may change in future versions,
amongst other things... for testing...
Temporary download location:
http://www.jwm-art.net/default_downloads/njl-lv2-0.0.1.tar.gz
notes:
no custom gui yet.
risset scales: parameters have far greater range but ranges are fairly
arbitrarily set at this moment.
Makefile slimmed down version of that found in swh-lv2 by Steve Harris,
so plugins might/should build on osx.
regards,
james.
Hi,
Seeing as I'm stuck at home this evening, I'm toying with the idea of
having a go at porting a LADSPA plugin to an LV2 plugin.
Looking at the official doc for LV2 I nearly ran a mile (or ten), but
Lars Luthmans "LV2 programming for the complete idiot" has me almost
convinced I might be able to do it... (( I think this guide should be
promoted more )).
So,
1) Are there any reasons why LADSPA plugins should not be ported to LV2?
2) Is anyone doing this already, and if so which plugins? (aside from
those commonly known as already ported.)
3) Any suggestions for plugins to be ported?
Regards,
James.
hi everybody!
just a passing remark: it is very easy to filter out a troll. it is
however close to impossible to filter responses to trolling by people
whose mail i appreciate in general.
best,

Bob,
You better do 'reply to all'. So more people can give suggestions. I'm
not very experienced in that sort of stuff (yet).

Bob,
We don't post on top. Quote the relevant part and place your message
below, because of our mail archive ;)
About the licenses. I think Impro-visor should have the same license of
the GPL source you use (Jmusic or something(?)).
About setting up a mailinglist, one for users one for developers, that's
pretty easy.
I think this should help you:

Hi everyone!
I just compiled flac version 1.2.1 on my Linux Debian system. I got an error
in
examples/cpp/encode/file/main.cpp line 75
memcmp not declared in this scope.
I found out why: The file needs to include string.h or cstring. It doesn't,
at least not directly. I put it in and everything was alright. Thought I'd
just report it, so it might be fixed...
Kindest regards
Julien

Neither have I. If Fons sets out to insult me, he does so with the
thoroughly literate grace and style of an insulter with class. I'd
expect nothing less.
The disreputable miscreant prone to a withering turn of caustic phrase
we know as Dave Robilliard, on the other hand........

Just kidding.
Arnold, we're gonna need more popcorn.....
P.S Nice work on Jackmix. Works a treat here from a recent ebuild.
Might not be that pretty, but it goes like a train...
