Phonic Helix Board 12 FireWire MKII compatibility (linux/ffado)

by pete shorthose

Hi I'm thinking of picking up a Phonic Helix Board 12 FireWire MKII (soundcard mixer combo) Has anyone used this on linux with ffado and jack succesfully? If so, are there any limitations on linux and what sort of performance did you see? (latency vs load) (the ffado site lists it as "reported to work" but no specifics and it's not listed as supported) Also, I have a Ricoh R5C832 firewire chip in my inspiron 9400. I've heard Ricoh chips are problematic so can anyone recommend a suitable expresscard firewire interface? cheers, pete.

24-bit files and hisss....

by Bearcat M. Şandor

Folks, I'm a little bit confused. I have some 24-bit files that i downloaded. These files are reported by 'file' as FLAC audio bitstream data, 24 bit, 6 channels, 48 kHz, 18273600 samples I was able to play one of them at one time, a few days ago and now i am not. I hate it when people say "i don't know what changed" but i don't. All i get is hiss in the left channel from my stereo. I can play other 24-bit file fine, even 96khz tracks. I've tried mplayer, xine, and phonon (using xine) Any ideas? I am using my on-board intel hd audio. My asound.conf is as follows: cat /etc/asound.conf pcm.dmixer { type dmix ipc_key 1024 ipc_key_add_uid false ipc_perm 0660 slave { pcm "hw:0" rate 96000 format "S32_LE" period_time 0 period_size 1024 buffer_time 0 buffer_size 8192 #was 5120 } } pcm.pulse { type pulse } ctl.pulse { type pulse } -- Bearcat M.

Are there Guitar Tab Editors supporting uneven time signatures?

by Viktor Mastoridis

Hello to all, I play bouzouki and guitar and most of my music repertoire is in (Eastern European) uneven time signatures (5/8, 7/8, 9/8 etc). I was trying to write Guitar/Bouzouki tablature/notation of this music on Linux in the past but without much success. The main (hidden) problem with these rhythms is the grouping of notes, i.e. 5/8 can be 2+3/8 or 3+2/8, 7/8 is 2+2+3/8 or 3+2+2/8 etc... Thus the grouping of the notes needs to reflect this fact as it is essential for the performer. My experience so far: Songwite, Gnometab and Kguitar don't support this feature. Lilypond - great for output, covers almost all needs, but grouping has to be done bar-by-bar which is really time consuming. Chords are not supported well for now (name and display) TuxGuitar is amazingly easy for note input, but it doesn't support note grouping as well. I requested this feature on their forum some time ago but no response from the developers so far Exporting Tuxguitar to Lilypond is what I use at moment, but for a longer instrumentals in 9/8 with say, two bouzoukia, it takes days to edit/produce a clear tablature/notation. Any suggestions on this will be greatly appreciated. Viktor

jack trouble

by Atte André Jensen

Hi I have some trouble with jack, that I'm hoping someone here could help me with. First a bit about my system: It's a laptop running ubuntu 8.04 on a 2.6.24-23-rt kernel. I use an edirol ua-1a usb soundcard, since the buildin HDA soundcard seems to be total crap. Sometimes my jack (started with qjackctl) is "messed up" by a client, often caused by some kind of high load, either on cpu or loading large stuff. This happens both with my DAW (eXT2) and chuck (which is what I'm trying to fix the problem for right now). Is sounds like some kind of sync with the soundcard is messed up (how evert that sounds like), the sound is distorted in a very charasteristic way, with lots of crackling. The problem persists until I restart jack, then everything is fine again. If this could be fixed somehow, the hotfixes in the rest of the post are irrellevant, or only of general interrest. Now I figured I start jack from the commandline (something I never did before) on every song, to emulate the "restart jack" strategy mentioned above. I looked in ~/.jackdrc and found: /usr/bin/jackd -R -P80 -dalsa -dhw:1 -r44100 -p512 -n3 -s -S I I run that command, jack is started just fine. However sometimes it dies like this: subgraph starting at ChucK timed out (subgraph_wait_fd=7, status = 0, state = Running) It might be something I do wrong in my chuck code, but it's random places (always on a down beat) and never happens when jack is started from qjackctl. What does the above errormessage mean, and can this information be used to start jack differently to avoid the problem? Notes: 1( I played around with stuff after writing the above and it seems that jack can also crackle when started from the commandline. 2) I also tried to kill X and run from a terminal, same problem. 3) The problem seems to be related to the cpu load. If the load is over 80, the problem is almost always there, if lower than 60 it's sometimes there. 4) The problem (crackling noise) is also there with the buildin HDA intel. 5) I also booted my debian stable on another partition, same problem. It seems to me that it all boils down to jack. Possibly it could (should?) get a better soundcard (Behringer FCA202 firewire seems to work with linux), but would this really solve anything? Any input appreciated! -- Atte http://atte.dk http://modlys.dk

Renaming tracks in Ardour, not beeing showed in JackControl !

by sv-e＠sv-e.dk

Hi list After switching to 64Studio alpha 3 I have a problem, when I make a new track in Ardour 2.7.1 and rename the track to whatever i need, the new name is not being showed in JackControl with the renamed name but as "Audio X" and because of that I'm not able to route or disconnect any signals to the track due to the name difference. If I rename tracks, save the project shutdown Ardour and start it up again it's all okay. I must miss some settings but which ? I've paddled in and out menus anywhere without finding something I could adjust to fix the issue. Best regards Sv-e

demo song

by Tapani Sysimetsä

Hi, You can find a demo version of Metsänpeitto by following this link and clicking play-button in the player: http://www.kolumbus.fi/sysimetsa/music.html It was done entirely with 64 Studio (Ardour, Qsynth, ZynAddSubFx, Hydrogen, Creox...) Some of the tracks were played with laptop keys (while traveling in Africa), i have to re-play those some day. More songs coming soon... Amazing how much fun one can get out of a laptop, good bunch of Linux audio applications, echo soundcard, one small mic, earphones and children's 1/8 guitar. Tapani

Finale looked good, but i am biased against Finale and similar programs -- tried it and it was really complicated and unintuitive for me. mouse clicks and button presses often did not do what i expected them to! i never looked seriously at Rosegarden -- not to say it isn't a good program. i'm sure it is :) but i didn't want a full "music composition environment." by the time i enter music into the computer, it is fully composed in my head and/or on paper :). i suspect it is the same for many composers and musicians who spend most of their time off the computer, which is why i think a program like NtEd is so important. i just want something that can make beautiful scores without much fuss or a steep learning curve, but with a powerful editor so i can publish and archive my compositions in a semi-professional manner. what features is NtEd missing? I put it in a similar category as Seq24: it's a simple tool, but it does what it's supposed to do very well. I think it is aimed at a different audience than RoseGarden, though.

NtEd

by ethan a young

Hello, I am posting in favorable comment of the notation editor, NtEd. It has a very straightforward and simple yet powerful interface. It seems very well-designed, and has been much more stable than the alternatives on both my Ubuntu and 64studio systems. I come from a background with Windows Encore version 4.5, which I still run through Wine. However, I would like to switch to to a native Linux program. I've tried MuseScore, which seems powerful, but is complicated and has remained buggy on my system, including crashes and several compilation errors. Canorus seems promising, too, but does not seem to be as far along or moving as fast in development as NtEd. For the record, I am notating the following types of pieces: 1. four-part SATB 2. piano pieces 3. jazz lead sheets 4. small instrumental ensemble music What has other's experiences been so far with these new and developing programs? Ethan
