Right now I'm using Fluidsynth running a soundfont which I customized a good bit, but it's just not quite what I want; I want it recognizably a string section, 88-key range, rumbly power in the low, smooth but a definite bit of fuzz in mids and highs. I'll take any technology, and will do payware, as long as it runs well on 64-bit Arch Linux. Anyone got a recommend? -- Jonathan E.

Thanks. > Eventually I will buy a second microphone for stereo recording. Skip the dynamic mics for now and buy a matched stereo pair of condensors. I have a pair of small studio projects condensors and while I can't read the labels on them anymore, they still sound like on the first day. And this pair came with a stero mount;-) If you insist on going dynamic (only when you record directly on the mic, not for chamber and/o ambiance), decide between the SM57 and SM58 if you will. The SM57 seems better suited for instruments, the SM58 is the de-facto (backup) standard on many stages for good reasons. If you can't decide between the two, get a Beta58 or maybe an AKG in the same price-range. Worth it, the beta58 sounds better then the sm58... But for what you want, a stereo-pair of small condensors, maybe additionally a large condensor for voice. Or stereo pair of large condensors from AKG or comparable... - Arnold Was is the Studio Project C4's? I have a pair I use for remote recording...drum overheads mostly. Good value and they are pretty versatile with 3 capsule/patterns. They are around $350 for the pair. There are also some Audio-Technica 2020 condensers for $100 each. They might be okay too. Grekim

Ardour complains disk system can't keep up

by jim

Hiya, I've got a Zareason media box http://zareason.com/shop/MediaBox-5440.html with 8 GB RAM running AVlinux (a debian flavor); I use Ardour pretty much exclusively, that and the vi editor. The system can record a single track with no problem. It occasionally fails if I try to record two simultaneous tracks. If regularly fails if I try to record four or more tracks. The complaint is always that the disk system cannot keep up. Question: would just blindly replacing the spinning disk with SSD be a likely fix and an overall good idea? Question: what info should I capture and email to get appropriate help? Question: what commands will yield useful info for this diagnosis? (I like the command line but forget which commands do what other than the usual suspects for basic use.) Hopefully, with thanks, jim in SF

Midi player

by Bob van der Poel

Just wondering if there is a better (or even worse) command line MIDI file player other than timidity? timidity seems to work okay, but it seems to be pretty much abandonware with little or no updates over the last 10 years. Not to mention it's totally confusing set of options. OTOH, it seems to be pretty solid and works for me. So, maybe I should leave things alone :) Most of the time I play my midi files though a real synth, but there are times when using software is nice. Never sounds as good to my ears ... and I have to assume the software or the sound files? -- **** Listen to my FREE CD at http://www.mellowood.ca/music/cedars **** Bob van der Poel ** Wynndel, British Columbia, CANADA ** EMAIL: bob(a)mellowood.ca WWW: http://www.mellowood.ca

Axiom 25: using pads with Hydrogen only (+ qsynth on keyboard)

by jonetsu＠teksavvy.com

Hello, What would be the best way to have the pads of an Axiom 25 trigger Hydrogen only while the keyboard itself would trigger qsynth ? Qsynth has sounds on all 16 MIDI channels and it seems that it's not possible to disable reception for a specific channel channel. Nor turning the sound down for a channel. Is this at all possible ? I can see an app that would be in-between qsynth and the Axiom 25 MIDI input that would filter out MIDI input for a given channel, does that exist ? Also, in qjackctl there are two MIDI outputs for the Axiom 25. 0:USB and 1:USB or MIDI 1 and MIDI 2. Conencting 0:USB to Hydrogen and USB:1 to qsynth could maybe be the way, but then the Axiom 25 would have to be told to send pads to 0:USB and keys to 1:USB, which I'm not sure it can do. The Axiom documentation has a lot of zones and groups and such, but there's no section on how to actually achieve some results, with examples, apart from very simple connection examples. Any comments/suggestions appreciated ! Cheers.

Browser Audio

Hi List, I don't think I changed anything, but suddenly audio from my browser is extremely distorted. Supercollider and Banshee sound great though. I don't know how to begin troubleshooting this.

Bitwig and Jack sync

by Aurélien Leblond

Hello all, So, Bitwig supports Jack except for the transport part. I was wondering, is there any other way to manage to sync them? Some kind of other transport (midi?) master? Thanks in advance for any ideas, Aurélien

by hermann meyer

The Guitarix developers proudly present Guitarix release 0.30.0 For the uninitiated, Guitarix is a tube amplifier simulation for jack (Linux), with an additional mono and a stereo effect rack. Guitarix includes a large list of plugins, support LADSPA plugs, and now, new, as well LV2 plugs. The guitarix engine is designed for LIVE usage, and feature ultra fast, glitch and click free, preset switching, full Midi and/or remote controllable (Web UI not included in the distributed tar ball). Preset could organized in Banks, so a Bank could represent your "show". If you have any issue with Preset loading/creating/handling, please read here in our wiki how this stuff work in guitarix. It is straightforward, and maybe more intuitive then you guess. http://sourceforge.net/p/guitarix/wiki/EnhancedUI/#creating-presets This release fix some bugs in our faust based zita-rev1 implementation, add LV2 support to the guitarix racks and introduce some new plugs, GX based and as well in the LV2 format. new plugs: * GxDetune (gx / LV2) * Baxandall tonestack(gx) * GxShimmizita ( LV2) * GxSwitchedTremolo (LV2) Please refer to our project page for more information: http://guitarix.sourceforge.net/ Download Site: http://sourceforge.net/projects/guitarix/ Forum: http://guitarix.sourceforge.net/forum/ Please consider visiting our forum or leaving a message on guitarix-developer(a)lists.sourceforge.net <mailto:guitarix-developer@lists.sourceforge.net>

Confusing qjackctl playback devices, no jackd output

by Roberto Suárez Soto

Hi, recently something weird happened. As usual in this cases, I'm not aware of making any changes, this happened all without my intervention. This reinforces my theory of a leprechaun infestation at home, but I'll leave that for another mailing list. The symptoms: I launch qjackctl, start jackd, and then hydrogen. When I hit "play", there is no sound. There are no errors in qjackctl's message window, and hydrogen is playing nicely (vu meters are going up and down as if nothing happened). After messing around for a while, I found that I could make hydrogen sound again changing the connections in qjackctl "Connections" window: instead of connecting the two outputs of hydrogen to "playback_1" and "playback_2" (which is the default as soon as hydrogen is started), I connected them to "playback_7" and "playback_8". I have a built-in HDA-intel sound card, and I believe that these outputs are "side-left" and "side-right". But I had never had to do this, playback_1 and playback_2 always worked. I'm using headphones, in case that's important. More interesting yet: while hydrogen worked flawlessly with playback_7 and playback_8, I tried to do the same with rosegarden and it didn't work. I haven't tested other jack-enabled tools yet, but I'll do it ASAP to see if hydrogen is the exception or the norm. Is it possible that due to some leprechaun-induced change in the system (or maybe, though not as probable, some change that I did and can't remember now) the playback devices in qjackctl have changed? How could I define them so playback_1 and playback_2 went back to their "proper" meanings? I'm aware that this is not really a well defined problem report, but I'll gladly welcome any suggestion or tip that could help with this. And with the leprechauns. Pesky little beasts. Thanks in advance, -- Roberto Suarez Soto Ave Nevis, ave ferrum, Ave tela, ave cruor, Ave pugna, ave moritur.
