Re: [fluid-dev] LADSPA refactor branch

[Ahmed Eraiba]

Hi jjc,

Sorry! I installed LADSPA plugins for windows not a library or sdk, even if I downloaded the sdk before I start, but never used it. sorry for that mistake.

>Even this question is not related to your recent LADSPA buiding issue, why did you use a c# wrapper ?

No problem, the reason dates back to 2013, when I did Midi projects in .net c# using NAudio and some external virtual midi synth, I then decided to try fluidsynth in the same projects, I used that time a c# wrapper and Sanford's Midi ToolKit. It was based on fluidsynth 1.1.6 (2012). As I'm not a professional programmer I stopped because of se limitations I encountered with sound quality and internal effects, so I focused back on my main profession (Elec. engineering), it is then only by coincidence that I found a post regarding another reverb! (thank you so much!) and a new release after long time, so I had a new interest to those old projects back!.

Regards, Ahmed

Hi, Ahmed and Marcus

 

Thanks to both for your informations, anyway there is something wrong.

@ Marcus.

1)If Marcus said that only a ladspa.h is necessary to build FluidSynth that means that Marcus has written all the necessary LADSPA host code inside FluidSynth sources files.

1.1) The ladspa.h seems only necessary for the LADSPA host code to reference the external plugins (usualy in shared library .so on Linux .dll on Windows) to be loaded

1.2) Consequently there is no need of a LADSPA library (regardless this library would be static (i.e xxx.lib) or dynamic (.i.e xxx.dll).

1.3) That means that the unknow library installed by Ahmed is unuseful.

@ Ahmed

1.4) Please what it the name file of the LADSPA library you have installed. ladspa.h is not a library.

 

@ Ahmed

>I'm using a c# 2010 wrapper for 1.1.6 and 1.1.8 worked perfectly when I build it.

Even this question is not related to your recent LADSPA buiding issue, why did you use a c# wrapper ?

 

Again thanks for your informations.

Regards

Hi jjc,

Here are what I already did up to now willing to try LADSPA for windows:

A) Yes there is a LADSPA lib for Windows

1) I installed LADSPA lib, but ladspa.h must be in include folder. So I did. The cmake should output ladspa.h - found

I'm stuck at this step so far...

Hi All,

> >

I would like to try this for windows. I usually configure and generate by cmake for visual studio 2010. The original 1.1.8 can be successfuly built, but not for this one with LADSPA support. 

> >

It gives a "cannot open include file dlfcn.h" error, but this file also depends on fearures.h and then "bits/dlfcn.h" (is it a different version of dlfcn.h?) But as I don't know much about LADSPA or its dependencies, could anybody help me on how to start making a successful try for windows? Thanks a lot!

Hi again,

I've added some more documentation that hopefully explains the effect signal paths in FluidSynth and how to replace the internal effects with LADSPA plugins:
