[ANN] Infamous Envelope Follower

Postby ssj71 » Sat Jun 29, 2013 2:18 pm

Its a lot more simple than the last but my second LV2 plugin is now working. It is an envelope follower based on the functionality of the peak follower in LMMS (original algorithm though). It takes an audio signal in and outputs a MIDI CC messsage based on the amplitude of that signal. If you have use for this plugin please give me feedback on how to improve it, since its not really one I use much in my workflow. Get it at: http://sourceforge.net/projects/infamousplugins/

Thanks. Reverse switch has been added and a control output port (note that the midi out is sample accurate, but the control port is probably plenty good). If someone would be willing to pull the devel branch and verify these features work as expected I'll merge them into the master (otherwise I'll test them out more rigorously when I can get to it).

:) The synth is ready, I'm working on them a lot so they might have frequent updates/new plugins in the next few weeks. Up to you if you want to wait or just do it now and update later. I'm in the developer mood lately. :D

just to follow up on this: Its now working in carla and jalv. All features have been merged to the master branch. Its crashing ardour3, haven't figured out why. I don't think I'll chase this much more anytime soon unless someone asks.

(slightly OT but Falktx, I couldn't figure out how to attach an output port to another plugin's port in carla, am I misunderstanding something?)

This synth looks like a very ambitious endeavor indeed! I can't wait to try it! Cool.. :D

Is it downloadable? Should I just download the install file?

The envelope follower isn't a synth, but we've been crossing topics a bunch about the infamous cellular automaton synth so what the heck :)
The code is "all done." I'm not aware of any outstanding issues (though there are probably some bugs someplace in there). To install the cell automaton synth download the source with this link: https://sourceforge.net/p/infamousplugins/code/ci/master/tarball
extract it, navigate your favorite terminal to the folder, then just run the install script contained there using

Code: Select all

./install.sh
You might need first to do

Code: Select all

chmod 700 install.sh
. If you have any trouble there is a thread for the synth itself, so we should probably continue there. :D http://www.linuxmusicians.com/viewtopic.php?f=24&t=11232
*EDIT* this will install both the infamous cellular automaton synth and the envelope follower plugin.

In short, right now you do:
1. go to the envelope-follower plugin built-in/carla-provided UI, in outputs tab and set it to some CC (say #1 modulation as example)
2. connect envelope-follower plugin events-out port to another plugin's events-input port (this being in the patchbay)
3. in the new plugin, set any parameter you want to automate by selecting the CC mapping to the same as before (CC #1 modulation)


Or just use the midi out port the plugin already has?... But that is still very useful to know. Thanks. Technically I could use anything with a meter like sc4 for example this same way right? (lets OT the heck out of this thread ;))

Thanks ssj71! I'll try it today. -I'm very curious to try it out.. :)

I keep getting errors when I try to install:

Code: Select all

make: Nothing to be done for `first'.
install -m 755 -p /media/Data/code/infamousplugins-code-git/src/EnvelopeFollower/envfollower.lv2/envfollower.so /usr/local/lib64/lv2/envfollower.lv2/

why is it saying that the .ttl file format is not recognized?

it's not recognized by "strip", which removes symbols from binaries. a ttl file is not a binary.

btw, the install path:

Code: Select all

/usr/local/lib64/lv2/envfollower.lv2/

looks a bit awkward...


What is it supposed to look like? All I did was run install.sh from the git, I didn't change anything.

? Why? I guess the extra lib64. I just copied the install path from the *v1 plugins by rncbc, but if you know a better way I'd be happy to listen.

tatch:
I take it you aren't on an ubuntu based system? I just pulled and built just fine on xubuntu, and I've tested pretty well on ubuntu studio. You can try to make only that plugin by navigating the terminal to src/EnvelopeFollower and using the commands:

Code: Select all

qmake
make
sudo make install


If its already built correctly (which it looks like it has if there's a .so in envfollower.lv2) you can also just copy that .lv2 folder into your lv2 directory:

Code: Select all

cp -r src/EnvelopeFollower/envfollower.lv2 /usr/local/lib64/lv2/envfollower.lv2

The install script basically just does that for each plugin. Sorry this isn't my expertise here, but I think we can get you running.

I'm using ubuntu 12.04 with kxstudio repositories. I used the commands you specified:

qmake doesn't print anything in the terminal, is it not supposed to?
make doesn't return any errors, so that's fine.
sudo make install returns the same errors I had before, all the .ttl files return "file format not recognized".

If its already built correctly (which it looks like it has if there's a .so in envfollower.lv2) you can also just copy that .lv2 folder into your lv2 directory:

cp -r src/EnvelopeFollower/envfollower.lv2 /usr/local/lib64/lv2/envfollower.lv2

The install script basically just does that for each plugin. Sorry this isn't my expertise here, but I think we can get you running.


I copied envfollower.lv2 to ~/.lv2/ since that's one of carla's default lv2 paths. Looks like it's opening up fine in carla now!

That's interesting. No clue where that error us coming from. Qmake doesn't give any output for me, so I think that's normal. Glad you got it working though. All make install sites your this is copy it to your lv2 directory anyway.
