Hey guys! I am sure I am not the only who notices that CALF Vintage Delay does not clean its buffer when you stop playing the tune in a sequencer. But just to be sure, here is a description of what happens. 1. You are in a sequencer (I personally worked in my first Linux days in LMMS, today work mostly in Qtractor). 2. You use CALF Vintage Delay. 3. You stop the track in the middle. 4. When you put the playhead to the beginning of the tune and start to play, CALF Vintage Delay will output leftovers from the previous position. This is not only annoying, most of the time it is confusing and even interferes with rendering a song. I don't know if I am correctly calling it a "buffer", but obviously CALF Vintage Delay does not clean up its memory after being stopped. Can anyone look into this, please? -- Louigi Verona http://www.louigiverona.ru/

Re: [LAD] Luppp live looper

Hi Louigi, Currently luppp's sync is like this: -resampling to achieve loop lenghts that correspond with "bars" in music terms. -BPM is currently set to a value, but dynamically modifyable trough MIDI (& GUI soon) -Resampling means that the pitch of loops will go up / down depending on playback speed I've fixed the pitch issue using the SoundTouch library, however it glitched & popped quite a bit too much. Either a better implementation using SoundTouch, or else I'm going to use libRubberBand, which seems to be the more widely used timestretch library. Due to the resample to "bars" code, if you record some material, but not to precise bars lengths it will be resampled (just a little bit) but will sound aweful in the harmonic sense :( See the following issue: https://github.com/harryhaaren/Luppp/issues/2 Cheers, -Harry

Help w/ debian report of mudita24 meters not working?

by Niels Mayer

I'm pretty busy with smaller devices and applications these days (e.g. http://code.google.com/p/voicetogoog/ ) however I got a report that mudita24's meters aren't working from the Debian maintainer of mudita24 and was hoping to get some help from other developers familiar with the issues. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=655708 http://code.google.com/p/mudita24/issues/detail?id=6 My hunch is the problem had to do with the Gtk changes that have been rectified in the most recent checkins. My first suggestion is that Ubuntu should update to Tim's latest Mudita24 commits (version 1.10 from svn: http://mudita24.googlecode.com/svn/trunk/ ). Any other suggestions aside from http://code.google.com/p/mudita24/issues/detail?id=6#c1 ? Thanks! -- Niels http://nielsmayer.com

Re: [LAD] AMS LV2 plugins: Version 0.0.6

The Fedora review has asked me wether it is GPLv2 (as in the license file) or GPLv3 as per the sourceforge page? I'm actually not sure here! The GPL is v2 in the code as it's the same one as coming from AMS. I chose the v3 kind of "by accident" on Sourceforge (i.e. I didn't pay attention!) To be honest: - I'm not even sure of what is the difference between the version 2 and the version 3 of the GPL. - The code is ported from AMS. Am I aload to change the license just like that? (it's crazy how although the concept of open-source is easy to grasp, it gets quickly more complex when you dive into the licenses themselves) Any advice here guys? It's my first open-source project and I'm kind of lost! @Fons: is it OK with you if I update the License to the GPLv3? Thanks in advance for your help. Aurélien
