I agree with F. Silvain. These pro audio distros mostly focus on graphical programs, which are generally not very accessible to screen readers, and thus aren't very friendly to visually impaired users. By contrast, on distros like Slackware and Arch Linux, if you only install the minimum packages to get a functional system, you only get the command line and no graphical programs at all (if you want some graphical programs, you'll have to install X). Then, you can install only what you want and build your custom system from there, just the way you want it, without being tied to Gnome or KDE or any other desktop environment you don't feel like using. For my graphical session, I currently use Fluxbox as my window manager," with keyboard shortcuts to my most used programs. For listing, accessing and copying files, I don't even use a file manager. I do everything from the terminal ("ls," "cd," "cp," etc.). I currently have Slackware on my general use machine. Even though I managed to get all my audio stuff to work (after much time and patience to write scripts and compile what wasn't available in the repositories), if I were to set up a new Linux box just for audio, I'd try Arch Linux since there are much more audio-related packages available in the Arch repositories than in Slackware's (including low latency kernels). There's also a talking installer for Arch Linux, specifically made for visually impaired users: http://talkingarch.tk/ Back to my setup... for audio, I use SoX[1] (command line) for batch-converting files, Audacity[2] (graphical) for editing (because it's very hard to cut/copy/paste/delete snippets of audio files from the command line, but Audacity's functions for dealing with multiple tracks aren't accessible to the screen reader, so I use Ecasound[3] (command line) for mixing. I use LinuxSampler[4] (command line) for playing virtual instruments in SFZ format, and Ecasound to record LinuxSampler's sound via the JACK ports (JACK is also run from the command line). I use two screen reader programs. Speakup[5] for the command line/non-graphical applications, and Orca[6] for the graphical ones. To run JACK along with a screen reader software, I have to use a second sound card, because the screen reader completely takes over the main sound card and JACK doesn't like this. I have a M-Audio FastTrack Pro (an USB external sound card), which I configured by adapting the instructions on the following link: http://joegiampaoli.blogspot.com/2011/06/m-audio-fast-track-pro-for-debian-… I couldn't find a MIDI editor that meets all my needs yet, and sometimes resort to a combination of Midish[7] and Midiedit[8] (both are command line programs), but I actually do most of my MIDI-editing from my hardware keyboard instrument. Speaking of which... > Date: Mon, 21 Dec 2015 21:54:51 -0500 (EST) > From: Karen Lewellen <klewellen(a)shellworld.net> > I am choosing the m-audio audiophile 2496 as a result for example. > Looked at a couple of Yamaha keyboards on Sunday, including the Motif fx8. > but without a well built house, one cannot move in the furniture grins. Motif XF8 is the one I have (yes, and it was a bit hard to fit it into my small-ish apartment :P ). The accessibility isn't perfect, but the keyboard has a lot of knobs and buttons, and is fairly usable by visually impaired users. Here's an archive with various files by the guy that previously ran the MoAccess Mailing List[9] (a mailing list for visually impaired Motif users), with button layouts, accessibility notes, menu references, and some audio tutorials, for various keyboards from the Motif line (classic Motif, ES, XS, XF). The problem is that it's a big archive, and you can't choose specific files to download (you have to download everything): http://blog.bryansmart.com/2010/10/14/moaccess-archive-update/ And on the below link you can find text versions of manuals for various Yamaha keyboards, including the Motifs: http://www.yamaha.co.jp/manual/english/text/index.html I have the XF8. Transmitting MIDI data to/from Linux (either via USB or a MIDI cable) works fine. What doesn't work, is making the keyboard behave as an external sound card, because this function needs some firewire hardware that Linux doesn't support. If you want a keyboard that doubles as an audio interface/sound card, you might consider MOX8 or MOXF8 (the lower range keyboards from Yamaha's Motif line), which can perform the sound card function via USB, and work fine on Linux.

Programming tutorials.

by John Murphy

I had been looking for a good basic Qt programming tutorial and, having found one, I thought other LAU subscribers could be interested. Qt seems to be the preferred language for many Linux projects, and my favourite desktop environment is written in it. The Qt5 tutorial is quite new and there are many others available from the same site, including for PyQt. http://zetcode.com/ --

Just weighing in on the single window debate - Will, you're my favourite linux-audio-user, but I'm gonna have to disagree with you on this one :P I much prefer having one window by default - especially when on the road with a laptop - BUT then being able to undock and reposition panes when I wish. I like the way Renoise handles it (you can detatch the sample editor) and the way the video editor kdenlive does it. Pretty much the IDE-like model people have mentioned. As far as the technical details go (MDI and all that), I need to do some research. Might have to do a poll of users at some point to see what people would prefer the default to be. Best, Oliver

Plugin for bass to resemble the Big Muff Pi Bass pedal?

by Bent Bisballe Nyeng

Hi all-knowing community :-) I am about to do a mix of a bass recording which we previously have done using a big muff pi bass pedal. This time around is has been done direct in so the input is a clean bass signal. I am not in a position where I can do a re-amping session so I am in search of a pure plugin solution that can get me as close to the big muff sound as possible. The Big Muff Pi Bass in action: https://youtu.be/PeCAJQcgeTA?list=PLD95311E52D27F1EA&t=19 I am thinking that perhaps one of the guitarix lv2's can be of assistance? I not at all experienced in mixing guitars/basses so any information that can help me find a usable plugin will be greatly appreciated. Kind regards Bent Bisballe Nyeng

Alternative FluidSynth GUI?

by Dan Capp

Research tells me that QSynth seems to be the only currently available/usable GUI for FluidSynth, but I get big xruns whenever I try and use it. FluidSynth itself doesn't cause me problems (I know because I'm able to use the FluidSynth-DSSI plugin fine in Rosegarden etc). The problem is that I want to use FluidSynth with Ardour3, but Ardour3 doesn't support DSSI plugins yet. So the only solution I have is to find a standalone interface for FluidSynth and then to link up using Jack. I looked at the old GUI 'FluidGUI' but it seems to be so old that it won't properly install on recent versions of Ubuntu. So does anyone know of: 1) A GUI for FluidSynth other than QSynth and FluidGUI?... or 2) An application other than the above 2 which would allow me to load soundfonts? Thanks in advance. - Dan

If you put [ or ] or press any of the keys referring to a filled loop slot when typing in the set name field, it still takes the keys as loop triggering of changing the set page. This behaviour appears to be fixed in the subatomicglue version suggested to me by Xavier http://www.subatomicglue.com/seq24/ > >> - Fix glitch with overlaps in loops > >Which glitch? > This is a bit unspecific, isn't it? Will require me revisiting some old seq24 sessions to figure out what it means. Might be in song mode or live mode :S I *think* it means that when you enter a long repeating loop in song mode - but in separate mouse draw strokes - it won't continue notes that overlap. There will be a noticeable cut. It's tricky to get loops drawn wider than your screen is. Perhaps they should be merged automatically. >> - Toggle loops in song mode > >Isn't that what live mode is for? ;) > It is, but why not not be able to add one-shots or extra layers exactly when you feel them while playing the song? Having to pause and switch to 'live' mode wont work live, and it's near impossible to manage loads of layers just live mode (at least for me, maybe with MIDI control perhaps?). I want to be able to record and layer pattern switching in live mode to fill out the song view. >> - Midi send if halfway through note (can be enabled / disabled in preferences) > >Could you explain this feature? > So if a loop has a note that starts outside the pattern, it isn't triggered. I think they should begin playing as soon as part of the note is hit by the playhead. >> - Draw whole notes instead of cutting off early in song mode loops > >You mean in the Song Editor window or in the main window? > In song mode when you split loops, it's frequent that notes will be cut in half, becoming stuck on or not playing at all.

It happens quite often so I should be able to reproduce - seems to be after lots of dragging loops between different slots. It's fixed after a program restart. >> << Challenging (significant new features) >> >> - Add Box select in song editor (REAPER style) > >Isn't that what live mode is for? ;) ?? When editing individual loops you can box select notes.
