Yoshimi continues to grow, and today we have V 1.3.4 out there. There are times for big things, and times for great things, but today was the time for (lots of) small things :) Less about features, more about user 'comfort'. Enjoy. -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

Sequencer drum voice assignment - Was: Behringer and Linux

by Ralf Mardorf

Hi Len, I didn't keep the Message-ID of the original thread. On Sun, 29 Mar 2015 23:01:19 -0700 (PDT), Len Ovens wrote: >Tracktion is not good enough to switch for me.

Sequencers should provide a matrix to assign each drum voice to an individual different note on any wanted MIDI channel. Some sequencers do provide such a matrix. I own a DD-11 too and it's owner's guide mentions that it provides 3 kicks, they are assigned to C1 (36), G#1 (44) and A1 (45). IOW 2 of the 3 bass drums are assigned to note numbers, that don't match with GM, so just mapping to MIDI channel 10 not always does the trick. My RX21 provides a kick on A1 (45) only and my TG33 provides the bass drum on C1 (36), G#1 (44) and A1 (45). G#1 (44) and A1 (45) on GM devices are for Hi Hat and Tom, that is the way as my Roland MT-32 and my Alesis D4 factory drum kits provide it. GM might be useful for some needs but for studio work a matrix is needed. IMO a drum kit by default should match as close as possible to GM, but it's common practise to use drum samples from different devices, so a matrix is needed anyway. Regards, Ralf

[ANN] Qtractor 0.6.6 - The Lazy Tachyon is out!

by Rui Nuno Capela

And finally, for the wrap of the pre-LAC2015@JGU-Mainz [1] release party, no other than the 'crown jewel' of the whole Qstuff* bunch ;) Qtractor 0.6.6 (lazy tachyon beta) is out! Release highlights: * LV2 and VST plugins GUI position persistence (NEW) * MIDI clip editor record/overdub note rendering (FIX) * VST plugin recursive discovery/search path (NEW) * VST-shell sub-plugins support (FIX) * also some old and new lurking bugs squashed. Qtractor [2] is an audio/MIDI multi-track sequencer application written in C++ with the Qt4 framework. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio. Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Downloads: http://sourceforge.net/projects/qtractor/files - source tarball: http://download.sourceforge.net/qtractor/qtractor-0.6.6.tar.gz - source package (openSUSE 13.2): http://download.sourceforge.net/qtractor/qtractor-0.6.6-16.rncbc.suse132.sr… - binary packages (openSUSE 13.2): http://download.sourceforge.net/qtractor/qtractor-0.6.6-16.rncbc.suse132.i5… http://download.sourceforge.net/qtractor/qtractor-0.6.6-16.rncbc.suse132.x8… - quick start guide & user manual (see also: the wiki): http://download.sourceforge.net/qtractor/qtractor-0.5.x-user-manual.pdf - wiki (help really wanted!): http://sourceforge.net/p/qtractor/wiki/ Weblog (upstream support): http://www.rncbc.org License: Qtractor is free, open-source software, distributed under the terms of the GNU General Public License (GPL [5]) version 2 or later. Change-log: - MIDI clip record/reopen to/from SMF format 0 has been fixed. - LV2 and VST plugins GUI editor widget position is preserved across hide/show cycles. - Added application description as freedesktop.org's AppData [6]. - Added a "Don't ask this again" prompt option to zip/archive extrated directory removal/replace warning messages. - MIDI clip editor (aka. piano-roll) gets lingering notes properly shown while on record/overdubbing. - Current highlighted client/port connections are now drawn with thicker connector lines. - Fixing segfaults due to QClipboard::mimeData() returning an invalid null pointer while on Qt5 and Weston. - Return of an old hack/fix for some native VST plugins with GUI editor, on whether to skip the explicit shared library unloading on close and thus avoid some mysterious crashes on session and/or application exit. - Force reset of plugin selection list when any of the plugin search paths change (in View/Options.../Plugins/Paths). - Recursive VST plugin search is now in effect for inventory and discovery on path sub-directories (VST only). - Non-dummy scannig for regular VST, non-shell plugins, were doomed to infinite-loop freezes on discovery, now fixed.

There is no documentation for jack_control and if I recall jack_control -h or --help do not work either but jack_control on it's own does. I think it is just a python script so looking through the file with an editor or pager would work too. I like jackdbus because the application that starts it is not the only one that can manipulate things in it. I find it very flexable. However using what you are used to is a great idea.

I was going to ask if you had tried the ALSA FW stack. > On the click side of things, I've found a firewire debug setting and turned > it up and can now see that the clicks correspond perfectly to kernel > messages like this: I do not know enough about fw to say. I don't recall now if you are still using a desktop (as with the d1010s). If so I would try moving the FW interface to different slots to see if this helps. Prioritizing the irq of course helps too, but I am assuming you have already done so. trying 32/3 instead 64/2 or any */3. This is just generally a good idea with any "networked" audio IF such as FW, USB or AoIP. -- Len Ovens www.ovenwerks.net

Difference between Yoshi 1.3.3 and Zyn

by david

Just noticed what appears to be a difference between Yoshi and Zyn when using otherwise identical settings. I have an improv thing I do that involves holding a low D (as a drone), sustain pedal down, the stock Cathedral 1 reverb, using the Flanged Pad 1 instrument. Then I play a bunch of descending scales, just letting the notes accumulate. On Zyn, no matter how many notes I play, the low drone remains; if I lift the sustain, the lower note is still playing. On Yoshi, after a certain number of notes, the low drone stops; if I lift the sustain, the lower not is NOT playing. I put the Yoshi and Zyn screens side-by-side and it looks like the settings are the same in each. What's up with that? -- David W.

hmm, updated to yoshimi 1.3.3 in debian sid repository AND

by david

it shows only one bank? I go Instrument > Show banks, it shows me only a bank named "#42. yoshimi" I go Instrument > Show instruments, it shows me a bank named "42. yoshimi" - and that's it. Clicking arrow beside bank name does nothing. Clicking Refresh banks changes nothing. Oh, so now I have to select a bank, click Make Current, and then I can see the banks? Hmm, seems to me that it would be nice if there was a single "bank" that listed everything. Finding an instrument now means first figuring out which bank it might be in, making that bank the current one, then looking through that bank hoping it contains the instrument I'm looking for ... I think the other way was less cumbersome. Haven't time now to see what impact this might have one instruments in my Rosegarden studio setup, will have to see how that works out. Thanks for the update, still the neatest sound maker in the collection! -- David W. Jones gnome(a)hawaii.rr.com authenticity, honesty, community http://dancingtreefrog.com

Maybe we could add a Search function - type in "Violin", hit Search, get list of all instrument names containing search phrase, regardless of "bank" number? David W.
