Adding Plug ins such as VST and LADSPA

One interesting experiment would be to have a skilled engineer mix a pop/rock song using a $250 reverb and then try to make a similar mix using one of the best LADSPA/LV2 reverbs.
Then you'd have ten other engineers listening to the tracks and answering these questions in order:

1. Which reverb would you pay $250 for?
2. Would you pay for that even if you could have the other one for free?
3. Would you consider using the free one regardless?

Now, the twist would be that only six would listen to the free vs. nonfree. Two would hear the $250 and another one in the same price range and two would hear two good free ones. Or you could split it 4-3-3.

Then maybe do the same test with ten "people from the street" and slightly modified questions.

I don't doubt that some commercial plugins are far better than the free ones but the question is more; are the free ones that bad and can people really hear the difference in the context of a song.

I made a demo mix once where I had to stretch a short solo bassnote that would fade out while only the singer stayed on top. Since I'd forgotten about the rubberband function (only came to think of it right now actually) I cut out a small portion of it, copied the fragments next to each other and added a global fade.
When soloed you could clearly hear the "sawtooth" amplitue where the piece restarted after each short fade. But with the singer on top of it and with her slight vibrato there was no way to tell that there was nothing but a natural fade to the tone.

It's worth remembering too that there are millions of outboard devices out there are perfectly Linux compatible, assuming you have a few spare analog or digital IO ports.

The lower end Lexicons are great reverbs, and still have the edge on most VST plugins. They also don't slowly lose compatibility with current OS/DAWs when a company stops supporting them, or closes their online authorisation servers.

You can get 90% of the way there with jconv though. The only thing it can't do is the heavily modulated patches.

There are some great collections of impulses here:

OK. You convinced me ;-). Has anybody tried to transform the free Glaceverb VST to LADSPA? And still there is a problem: I need a working possibility to trigger my drums. I usually did this with the KT-Drum Trigger (freeware). If it would be possible to create a plug in using jack as midi-connector to write a midi-signal in any midi-aplication on linux, this would be great. For the higher end productions I need a possibility, to trigger drums (sometimes the bassdrum with a lower sinus tone). Then we could talk about getting further. And a paragraphic equalizer in every track would also be great, just like in protools and cubase.

What I additionally wanted to say: I want to support the ardour community financially. But I wanted to get sure first that I have no loss of quality in my productions. But if it's really possible, that effects and aplications get changed for personal needs, then I think I will try it, and make the next production with ardour.

First, the Glaceverb homepage (http://www.dasample.com/ AFAIKT) seems down and second it seems only free as in beer and not in speach, meaning there seems to be no source code to start porting from.

As for paragraphic equalizer the only thing looking like this http://www.waves.com/objects/Images/Screenshots%5Csshot_big_q10_01.jpg in the linux world would be Jamin's EQ but inserting that on each track would require a really fast CPU. But do you really need more than three or four sweepable EQ's (Triple parametric/4-band parametric) on each track?

No, never. But a graphical view of things is always really helpful. Paragraphic only means a mixture of graphic and parametric eq. The number of bands is optional. 4 bands are enough. But for sweeping through frequencies a graphical drag and drop interface is really helpful and saves a lot of time during a album production.

Here's an actual link to the dasample glaceverb http://www.kvraudio.com/get/1566.html

I don't think it would take you that long to get used to a non graphic display for sweeping. After all you primarily listen for the right freq, right?
And the LV2 version of the 4 band (FIL) has graphics as well: http://nedko.arnaudov.name/soft/lv2fil/ , even if you can't drag the curves.
*Edit*: To use this you might need to patch Ardour with http://nedko.arnaudov.name/soft/ardour2-r5126-lv2_external_ui.patch or use lv2rack from zynjacku (can't give an URL because the spam filter won't let me) to load it externally.

Yes I found the KVR page but the "Free download" link points to the dead dasample page.
And I'm pretty sure the download only contains a dll anyway.

Regards triggering your drums, if MIDI works for you there is a program called a2jmidid that can be used to route JACK MIDI to ALSA midi. It runs as a JACK application - you can use it to route JACK MIDI in to a MIDI Thru port and you can then route that MIDI Thru into the MIDI in of any ALSA-aware application (which is most of them). I use this with VST instruments for real-time performance, all the patching can be done through QJackCtrl.

What he wants is a program that converts the analog drum sounds into MIDI info based on the frequency of the sound. I'm not aware of any linux program that does this (maybe ecasound or pd or some of the more exotic software).

If he's really lucky the KT plugin will work in Ardour otherwise signing up to Linux Audio Users (http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user/) and asking around there might be a better chance of getting good info.
