Hi all, Sometime in the next 3 months I hope to release a new album. I wish to completely avoid the record companies - as I got burned badly in the 90's - and they still don't seem to get the deal with regards to open, friendly licensing for 21st century. So I'm looking at releasing on the web independantly. I know what I want: - host the CD 44k, DVD 48k images and individual tracks - provide CD covers/labels etc. for dl and printing - provide some way of previewing/streaming the tracks online - provide some kind of ratings/feedback section - provide a way for people to pay for physical media if they want a disk delivered to their door - lastly, make sure that if someone plays a track or CD with ITunes or Amarok etc. that all the graphics, info, homepage etc. appear in the program But I have absolutely no idea where to start! Any info/ideas would be greatly appreciated. Especially in regards to webhosts that are friendly for this sort of thing, and links to other artists that have done this successfully. - shanerich

Re: [LAU] How to adjust note velocity in a midi file

Mididngs looks like it may help some... What I really want is an application that will play back my midi files, and allow me to change the velocity on-the-fly. And it need to be able to save the new velocity... Sounds kinda impossible, I know. If I knew anything about MIDI, I might try making it myself... -- Christopher Stamper Email: christopherstamper(a)gmail.com Web: http://tinyurl.com/2ooncg gTalk: http://tinyurl.com/6e359r Skype: cdstamper

How to adjust note velocity in a midi file

by Christopher Stamper

Hi all, I've got a bunch of MIDI files that I want to import into rosegarden. However, all the notes are at max velocity, making it sound kinda mechanical. I know that I can adjust the velocity value from within rosegarden, but each not needs set independantly. And that could take some time... Is there some kind of application that can adjust the velocity of notes in a midi file, perhaps reading it from my midi keyboard? Thanks! -- Christopher Stamper Email: christopherstamper(a)gmail.com Web: http://tinyurl.com/2ooncg gTalk: http://tinyurl.com/6e359r Skype: cdstamper

midi: noise on atack notes

by ::surian::

Hi Folks, When I use my midi keyboard with some programs like horgand and amsynth, i have some noise on the atack of every note. It's some sort off a trigger-noise.. every time i press a note comes a glitch.. Like a "note-on" noise... But when I use Zynaddsubfx I don't have this problem. weird.. I think it's a bad configuration off my midi setup, but don't know what... Somebody know what's hapening here? I use am m-audio axiom 49 midi keyboard and a m-audio audiophile 2496 soundcard to do my stuff. Connect this synths via JACK with latency around 8ms thanks surian

news: Loomer VST plugins and the pizmidi plugs

by Dave Phillips

Greetings, While browsing KVRAudio I happened to find news of the release of three new VSTs for Linux (native .so format) from Loomer : http://www.loomer.co.uk/ Aspect is a polyphonic synth. Resound is a delay/echo unit, and Manifold is a harmonizer. They're available as plugins or standalone versions, they support ALSA and JACK audio/MIDI connectivity (including JackMIDI), and all appear to have been created with the JUCE framework. I checked out the demos for Aspect and Resound, they worked very well in their standalone versions. Please note that these are commercial products, prices can be found on their Web site. Also note that I have nothing to do with Loomer, they don't even know I'm posting this announcement. Fans of native Linux VST plugins might also be interested to known that the pizmidi plugin collection was updated in December. These free plugins (source on request) are some of the most useful helpers in my MIDI work, you can check out the variety here : http://www.kvraudio.com/forum/viewtopic.php?t=192282 Piz has added some neat new plugins, they all work perfectly in the JOST system. No standalone versions, sorry. Again, I have nothing to do with the creation of this software beyond my work with them as a user. Best, dp **

[ANN] Nama recorder-mixer version 0.991

by Joel Roth

Thanks to the patient testing and suggestions by Julien Claassen, I'm pleased to announce a shiny new version of Nama. New features since the last update include: - Auto JACK detection - Play head repositioning works properly with JACK (thanks, Kai!) - Full support for Ecasound controllers (and controller-controllers) In GUI mode, click on the target parameter label - Auxiliary sends to a soundcard channel or JACK client - Preview mode tests setup without writing WAV files - Autocompletion for text commands and project names - Recognize all ecasound-iam commands from int-cmd-list - Command parser seems to work perfectly - Automatically update effects data cache detecting new LADSPA plugins and Ecasound presets - 'bunch' and 'for' commands for executing commands on several tracks at once - A 'null' group for a metronome track Other recent improvements: - Autoconnect of JACK clients as track inputs - Arbitrary track width (stereo and mono commands) - Track soloing (solo/all commands) - Find_effect command. 'find_effect chorus' lists plugins/presets/controllers containing 'chorus'. You can use multiple keywords. - Support Ecasound input objects playat, select, audioloop, reverse - Looping over chain setup between arbitrary points You can install from CPAN thusly: cpan Tk cpan Audio::Ecasound::Multitrack (Other dependencies: Ecasound, LADSPA SDK, BSD 'file' utility) Or get the sources from github: git-clone git://github.com/bolangi/nama cpan Text::Template cd nama/src ./build ./ui (runs Nama) And if this works: cd .. perl Makefile.PL make make test make install Nama's current feature set more or less completes my vision for a SuperEcasound. Provided there is sufficient interest, it would be nice to consider future developments such as adding record/playback of realtime MIDI controller inputs, fades, LASH support, and convenient setup of multiple buses. Thanks to all who've helped and inspired. Joel -- Joel Roth
