Re: [LAU] [LAD] Summercode 2008: LASH as a D-Bus service

by Nedko Arnaudov

Juuso Alasuutari <juuso.alasuutari(a)gmail.com> writes: > - Turn LASH into a D-Bus service daemon. Do you mean lashd becoming a D-Bus service? If so, do you imagine having logfile like of jackdbus? I think it is quite important what will be changes for users of LASH. The things you mentioned are changes either to internal implementation or API. IMHO, all changes should be driven by desire to solve current problems that LASH user have (as human using the whole thing, not as API user). Thus problems that people have with LASH should be taken into account. Here are my problems with LASH: * auto-launching without logfile means no proper handling of lashified apps stdout/stderr. It should have logfile, with prefixing output of apps. * lash is of mercy of libjack and crashing jackd often causes lashd kill. This is just wrong. lash should be able to restart jack, tell jack apps that jack server is started again so they can reconnect to jack server and finally lash can restore jack connections. * lash should preserve at least basic properties of currently started JACK server, such as sample rate and availability of hardware ports. When loading session whose JACK parameters dont match, user should be given options what to do. * there is no export/import "tarball" (single file) functionality, to be used for backup of sessions and transfering them between machines * lash apps should be allowed to do "light save", with app session referecencing files/resources external to lash. This means for example that such lash light save should not copy ardour wav files that are linked (not copied) to lash directory. * lash should be able to manage not lashified apps at least to extent of launching them and connecting their ports. * there is no good GUI for controlling lash. probably [wm]glashctl fixes this. lash_panel use is PITA. Usable GUI should be part of the lash tarball. Also, X11-less operations should be still possible (command-line or ncurses). * lash does not preserve X11 related properties of apps, like on what screen (dual-head) they were. * when opening/importing session, lash should be able to either replace current session or merge it, to allow combining several simpler sessions into more complex ones Things that I'm not personally interested on (I don't think they worth but there is nothing wrong if support for them is there, unless this makes implementation much more complicated and thus bug-prone): * Supporting connections for things other than JACK (read ALSA seq) * Supporting multi machine sessions (several machines in a network used in common session). * Creating "universal" fit-all solution that works for every single app on every single OS and thus, not being able to it at all using available resources. This does not mean that support for other OS-es should be avoided intentionally. Still, I need *Linux* Audio Session Handler, not LASH Audio Session Handler. I plan to donate my time to fixing LASH, after I (with Juuso's and Marc's help) finish with jackdbus (patchbay and transport control interfaces are still mising). I'd like everybody who has problems with current state of LASH to write them in this thread. -- Nedko Arnaudov <GnuPG KeyID: DE1716B0>

Aldrin and Softsynth

by Luigi Curzi

hello to anyone does someone use aldrin? it seems a good software and the main programmer's (paniq) music is very very good. i want know if is it possible to connect aldrin with external sofsynth or midi applications (as zynaddsubfx or hydrogen) and if it is possible, how? thanks in advice.

Anyone know why the Phasex site is not available.

by Nigel Henry

Just wanting to see if newer versions of Phasex are available, I tried: http://sysex.net/phasex Anyone know why the site has seemingly gone down? It's a nice synth, and want to see if it installs on Archlinux without problems. I do have phasex-0.11.1.tar.gz available, so can install it on Archlinux, but where has the site gone? Nigel.

ZynAddSubFX & MIDI

by holotone＠gmail.com

So I've been working on getting my Axiom 49 MIDI keyboard to play nice with ZynAddSubFX, and am having only limited success. Using this guide for reference ( http://zynaddsubfx.sourceforge.net/doc_3.html ), I'm able to get all the standard stuff working, but am running into a bit of a brick wall when it comes to the NRPN section; My biggest problem is lack of understanding, methinks - Any pointers for getting this controller to speak NRPN for someone who doesn't even understand what coarse / fine and all of the hex values mean? My dream scenario would be MIDI setup similar to how amSynth works - Config would be much more easily handled from the software as opposed to the hardware, though from what I understand of Zyn, this isn't possible - Correct me if I'm wrong, though! Thanks, -- ~holotone http://holotone.net/

I seems > that the ZynaddFx has only one sound, but thats a small problem, (I > hope). Just under the "Reverb" (light blue) part on Zyn, and on the right is an empty combo box. Click on that, and it will open the banks window. On the top left is a white combo box with an arrow to the right of it. Click,and hold on that, and you will get a menu of the available sounds. Scroll down while holding, and click on something. Synth piano for example, and you'll get a bunch of different sounds in the banks window that you can choose from. > > So, sound is working. Don't know how. But still no keyboard. Which model of Yamaha keyboard is it. I have an Evolution one (usb), but perhaps there is some control on your's that needs enabling to send midi through the usb. I presume you've done all of this, but just to check. Open Qjackctl, press start to start the jack daemon. Click on "Connect", and in the Audio tab highlight zyn on the left, and alsa_pcm on the right, and click the connect button. Now Click the MIDI tab, or the ALSA one, if it's a later version of Qjackctl. Your keyboard should be on the left, and Zyn on the right. Just highlight them, and again click on connect. > > The soundcard is: > 00:11.5 Multimedia audio controller: VIA Technologies, Inc. > VT8233/A/8235/8237 AC97 Audio Controller (rev 50) > > and the output you asked for is: > snd_rtctimer 2432 0 > snd_via82xx 21624 5 > snd_ac97_codec 93408 1 snd_via82xx > snd_pcm_oss 37568 1 > ac97_bus 1824 1 snd_ac97_codec > snd_mixer_oss 13472 1 snd_pcm_oss > snd_seq_dummy 2564 0 > snd_seq_oss 26944 0 > snd_usb_audio 74048 0 > snd_mpu401 6888 2 > snd_mpu401_uart 6016 2 snd_via82xx,snd_mpu401 > snd_pcm 63688 6 > snd_via82xx,snd_ac97_codec,snd_pcm_oss,snd_usb_audio > snd_page_alloc 7432 2 snd_via82xx,snd_pcm > snd_usb_lib 13728 1 snd_usb_audio > snd_seq_midi 6144 3 > gameport 10376 2 snd_via82xx,analog > snd_seq_midi_event 5632 2 snd_seq_oss,snd_seq_midi > snd_rawmidi 17824 3 snd_mpu401_uart,snd_usb_lib,snd_seq_midi > snd_hwdep 6276 1 snd_usb_audio > snd_seq 40976 20 > snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_seq_midi_event > snd_timer 17284 3 snd_rtctimer,snd_pcm,snd_seq > snd_seq_device 6252 5 > snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_rawmidi,snd_seq > snd 41316 23 > snd_via82xx,snd_ac97_codec,snd_pcm_oss,snd_mixer_oss,snd_seq_oss,snd_usb_au >dio,snd_mpu401,snd_mpu401_uart,snd_pcm,snd_rawmidi,snd_hwdep,snd_seq,snd_tim >er,snd_seq_device soundcore 5376 2 snd > usbcore 109144 6 > snd_usb_audio,snd_usb_lib,usbhid,ehci_hcd,uhci_hcd Everything looks ok with your loaded sound modules above. > > > to me it looks like there is some midi modules loaded, but if its the > right ones I don't know. snd-usb-audio is needed for your keyboard, and is loaded. snd-seq-midi is needed for creating midi connections in qjackctl.
