Version 2.5 of jack-keyboard can be downloaded from: http://pin.if.uz.zgora.pl/~trasz/jack-keyboard/jack-keyboard-2.5.tar.gz The biggest change is switching from hand-written makefiles to autotools. This should make packagers' life easier. jack-keyboard is a virtual MIDI keyboard - a program that allows you to send JACK MIDI events (play ;-) using your PC keyboard. It's somewhat similar to vkeybd, except it uses JACK MIDI instead of ALSA, and the keyboard mapping is much better - it uses the same layout as trackers (like Impulse Tracker) did, so you have two and half octaves under your fingers. http://pin.if.uz.zgora.pl/~trasz/jack-keyboard/ -- If you cut off my head, what would I say? Me and my head, or me and my body?

Qtractor 0.1.3 (frugal damsel) released!

by Rui Nuno Capela

Greetings, After another quarantine period, I am pleased to announce (yet) another maintenance release of my flag-ship toy, Qtractor, an Audio/MIDI multi-track "bedroom" sequencer for the techno-boy (and girl:). Probably, the major feature highlight for this release, is the new optional support for in-place audio clip pitch-shifting through Chris Cannam's Rubber Band Audio Time Stretcher library. This one alone just closes the gap on the techno-boy/girl bedroom-studio prospects, so let's move along, nothing really new to see here :) However, given there were many inner changes in the audio rendering engine everything might just sound a lot less glitchy than previous releases. Therefore, everybody is welcome to upgrade. And please, don't be shy ;) Qtractor 0.1.3 (frugal damsel) has been released! Grab it while visiting the project pages: http://qtractor.sourceforge.net http://sourceforge.net/projects/qtractor Here's some direct links to the most wanted pieces: http://downloads.sourceforge.net/qtractor/qtractor-0.1.3.tar.gz http://downloads.sourceforge.net/qtractor/qtractor-0.1.3-user-manual.pdf And don't (ever) forget to drop by, over the upstream :) http://www.rncbc.org As usual, the complete change log is worth a look too, for the record: - As one may find convenient sometimes, the global time display format (frames, time or BBT) may now be changed on the main transport time spin-box context menu. - Left-clicking on the track list number column now toggles all track content clip selection. - Prevent audio-buffer initialization mashups when editing short audio clips while playback is rolling and within clip region. - Audio peak files gets a bit simplified, dropping the peak frame count from its header; peak waveform graphics are now rendered as straight lines when over the end of audio file. - The drop-span option (View/Options.../Drop multiple audio files into the same track) now also applies when importing tracks (as in Track/Import Tracks/Audio...) to concatenate multiple audio clips into one and the same new track. - Audio and MIDI meter level colors are now user configurable (as global configuration options, View/Options.../Display/Meters) - First attempt for Qt4.4 build support, regarding the bundled atomic primitives, which have changed upstream as advertised (thanks to Paul Thomas, for spotting this one first time). - Record monitor switch is now an accessible button option on all track mixer strips; for visual consistency, the old bus "thru" switch button has been renamed to "monitor". - Force track-view position reset to origin on session close. - Fixed segfault on inserting an external file into files widget. - Mixer splitter sizes are now better saved/restored when closed. - Track record monitoring is now a state option, being toggled from the Track/State/Monitor menu; applies both to audio end MIDI tracks: when set all input will be pass-through to the current assigned output bus, including track plug-ins chain. - Session dialog gets split in its own tab components, between descriptive, time and view configuration ones. - Drifting correction among audio and MIDI engines is now back, but avoided while recording or should it be while looping? (EXPERIMENTAL REGRESSION) - Time-stretching percent value gets its semantics inverted, as thought consistent with ones general sense for relative stretching ie., lower to shrink and higher to make longer. this is a major up-side-down change and should affect all sessions saved with time-stretched audio clips. - Slack space in main tracks and MIDI clip editor views are now proportional to viewport width, leaving enough room for drag and moving content past the current session length, specially at the lower zoom levels. - Clip end time is now also shown on tool-tip. - When armed for recording, MIDI tracks are now monitored and filtered through their own output bus, thus having the same behavior as audio tracks; this also implies that all record armed tracks won't playback their current content material when recording is engaged and rolling; track mute and solo states are now honored on record monitoring. - Audio clip pitch-shifting makes its first appearance, with the optional help from Chris Cannam's RubberBand library. - A new MIDI editor tool is available: note/pitch randomize. - Avoid (re)setting the default session directory if a session cannot be open or loaded for some reason. - Another nastiness bites the dust: a subtle but progressive drifting has been swept away from the audio buffer looping; zero buffer flushing is now also taken into account, which was the cause for serious drifting on time-stretched clips. - A major digital audio processing bug was tamed: audio clip fade-in/outs are now linearly piece-wise applied, even at the clip edges, giving a much smoother rendering and thus mitigating the nasty click-and-pop artifacts that were in fact due to some early design optimization with a poor and sloppy implementation.

ANNOUNCE: Rosegarden 1.7.0 released

by Chris Cannam

ROSEGARDEN 1.7.0 RELEASED The Rosegarden team are proud to announce the release of version 1.7.0 of Rosegarden, an audio and MIDI sequencer and musical notation editor for Linux. http://www.rosegardenmusic.com/ This release focuses mostly on notation enhancements, although there are also substantial bug fixes in other areas. The world of sequencer software for Linux is becoming increasingly well populated with projects designed for different types of user -- with the appearance of QTractor, a MusE stable release expected soon, Ardour 3 in the pipeline for studio users, as well as commercial software such as Renoise, and old favourites like seq24. This is great for Rosegarden, as it means we no longer feel we have to please everyone: we are able to concentrate on the area that we find most interesting for Rosegarden, namely as a sequencer for people who also like to work in notation. Of course, all of the other existing features will continue to be supported and to evolve, but we have a clearer focus for the future than we have had. The 1.7.0 release includes new contributions from established project members Heikki Junes, Arnout Engelen, and Pedro Lopez-Cabanillas. Translator Yves Guillemot has come over to the development side as well. New members Philippe Macaire and Jaakko H. Kyro have joined the development team, while Gunhild Andersen has joined us as a documentation writer. We have also had code contributions from Colin Fletcher, Alessandro Preziosi, Stefan Asserhall, "Flameeyes" Pettenò, and Anders Dahnielson, and a segment parameter presets database update from Magnus Johansson -- and many new device library contributions. Progress during this release cycle has been slow but steady, with relatively little developer time available from the core team, but for this release -- coordinated by D. Michael McIntyre -- we have managed to bring together more contributions from more people than in any previous release of Rosegarden. New Features in 1.7.0 * Track headers in Notation view (Yves, since rev 8355) * Test to see if a newer version is available, to help users stay up to date when distros sometimes carry quite old versions (Chris, since rev 8374) * New Welcome dialog that attempts to help you tweak your setup for best results (Chris, since rev 8374) * Notation: The preferred stem direction in a chord around the middle line is down, which better meshes with LilyPond (Heikki, since rev 8381) * Notation: The preferred beam position in a beamed group around the middle is below (Heikki, since rev 8383) * Add icons for Add tempo and Add time signature in NotationView -> Composition menu (Heikki, since rev 8415) * Move to Staff Above or Staff Below to make sorting out overlapping voice parts considerably easier (Chris, since rev 8545) * Radically reformed grace notes now work correctly for the first time in Rosegarden's history, and are now easy to use (Chris, since rev 8557) * Sync segments to track parameters (correct clef, transpose notation, alter key signatures, highest/lowest playable notes) available as option when using the load preset button in the Track Parameters Box, which greatly simplifies the process of converting a standard MIDI file into notation suitable for real musicians who play transposing instruments (Arnout, since rev 8583) * "Convert notation for..." function added to notation editor to provide another mechanism for using the sync segments functionality (Arnout, since rev 8593) * Expanded/corrected instrument presets database (Magnus Johannson, since rev 8597) * Export markers to LilyPond (Jaakko H. Kyro, since rev 8618) * Alternative shortcut for Play/Stop in laptop use: Ctrl+Return (Heikki, since rev 8626) * New track parameters for exporting square, curly, and nested brackets to LilyPond, making it possible to produce true piano notation and complex orchestral scores properly for the first time, without hand editing of the .ly code. (Replaces the now deprecated "Export staff group bracket" option with this new and much more flexible scheme.) (Michael, since rev 8637) * The transport mode setting is now stored with and restored from individual compositions (Philippe, since rev 8646) * Export the new radically reformed grace notes into LilyPond syntax (Heikki, since rev 8648) * Now ties can finally be flipped (Chris, since rev 8653) and the flipped ties exported to LilyPond (Michael, since rev 8655) * Arbitrary dynamics exported to LilyPond as markups if they are not on LilyPond's list of supported dynamic types (Michael, since rev 8687) * Manually repositioned rests (as when rearranging badly rendered overlapping voices) are now exported to LilyPond (Michael, since rev 8694) * Set a quick playback position marker in the main window with Ctrl+1 and recall it with 1 (Philippe, since rev 8705) (Sets working visual marker in rev 8803) * New variable height tracks finally make working with overlapping segments (eg. to contain concurrent voices for notation purposes) an easy and reasonable process, instead of the nightmare it has been for years (Chris, since rev 8740) * Smarter selections in matrix and notation views now allow you to remove individual, previously-selected events without beginning the entire selection process from scratch (Michael, since rev 8744 (matrix) and 8748 (notation)) New Documentation * Five new informal supplemental tutorials by D. Michael McIntyre: http://rosegarden.sourceforge.net/tutorial/ * Users Helping Users: http://www.rosegardenmusic.com/wiki/users_helping_users * Wiki moves from SourceForge to our own site: http://www.rosegardenmusic.com/wiki/ Significant bug fixes since 1.6.0 * Serious overhaul of MIDI import to avoid scrambling karaoke and similar files into complete chaos (Chris, since rev 8515) * Fix text codec dialog that appears when importing MIDI files with lyrics (Chris, since rev 8536) * Splitting the segment now really splits the segment (Chris, since rev 8538) * Track Parameters now displays the correct track (Chris, since rev 8539) * No more mysterious zero-length segments on import (Chris, since rev 8540) * Align lyrics with rests so they appear at the correct time, if only lyrics and rests in a segment (Chris, since rev 8541) * Fix inability to build without JACK (Flameeyes' Pettenò, since rev 8546) * Fix broken pitch chooser dialog to correct accidental display and draggability (Arnout and Michael, various revisions since 8555) * Replace perpetually broken grace note functionality (Chris, since rev 8557) * Fix crash when deleting a device that was in use (Chris, since rev 8558) * First note after 8va or 15ma section no longer at wrong octave (Chris, since rev 8559) * Correct display of flipped stems in certain situations (Chris, rev 8560) * Repair very tricky ruler bug that prevented the composition from being able to start anywhere other than bar 1 (Michael, since rev 8573) * Take track transpose into account when recording, move notation by the opposite amount, so the end result sounds correctly when played back (Michael, since rev 8576) * It is now possible to tie notes that have shorter performance durations than their display durations (Chris, since rev 8595) * Renamed spurious Halve/Double Speed functions to Double/Halve Durations and assigned new keybindings (Heikki, since rev 8615) * Headers for the files in the Rosegarden library rewritten so that all of them show up in everyone's file dialogs (Anders Dahnielson and Michael, since rev 8666) * The notation view no longer assumes it is always necessary to display a time signature, which eliminates a lot of extra time signatures that used to have to be hidden by hand (Chris, since rev 8679) * Above/below directions of phrasing slurs now exported to LilyPond correctly (Michael, since rev 8680) * Hidden key signatures ignored during LilyPond export (Michael, since rev 8693) * Corrected a problem whereby you could edit the second of two markers at the same time position, and have the changes apply to the first one at that position (Philippe, since rev 8706) * Build system tweaks and a fix for building with librdf in an unusual location (Pedro, since rev 8829) Thanks to * Damien Goutte-Gattat * Oliver Večernik * Tony Amort * Steffen Klein * Haig Dedeyan * Luis Filipe Lobo * Marko Mueller * Emanuel Rumpf * JP Morris * "Piglet" * "b.ohnsorg" Chris
