Hello. Does the linuxsampler.sourceforge.net really work as a full-blown sampler? What else I need for using it? >From: Paul Winkler <pw_lists(a)slinkp.com> > >As for writing a sampler in csound: [ ... ] and it can use the diskin >opcode to play sounds directly from disk. However, the latter isn't very >responsive in realtime IIRC, so for good playback you need to use >the in-memory approach, which means you're limited by your physical RAM. Just add the low-delay trick to the diskin opcode. The trick is dated at least down in 1995 (patent is 1997). By the way, what Csound I should use? Unofficial linux Csound does not work with Hankelson's instruments, and official Csound has no ./configure for easy install. Is PD or similar better supported? Has anyone orc-to-pd converter so that I may use Hankelson's instruments in PD? I must repeat what others have said: we need good examples and demos. I tried to check good Csound demos but no such thing available. Examples were from dull to the worst kind of monotonous tones. Juhana

[linux-audio-user] getting fluidsynth to read from ALSA seq

by Adrian Prantl

Hello! Today I tried to use fluidsynth as a software synthesizer to Rosegarden4. I followed the tutorial at http://linux-sound.org/quick-toots/4-sequencers_and_softsynths/quick-toot-m… . But when I try something like > fluidsynth -m alsa_seq -a alsa -o "midi.alsa_seq.device=VirMIDI 2-1" midi/gs.sf2 fluidsynth reports: > ALSA lib seq.c:181:(snd_seq_open_noupdate) Unknown SEQ VirMIDI 2-1 So my question: What is the correct name for ALSA sequencer port 81:0? thanks, adrian adrian@vicviper:~$ aconnect -i client 0: 'System' [type=kernel] 0 'Timer ' 1 'Announce ' client 64: 'Rawmidi 0 - MPU-401 (UART) 0-0' [type=kernel] 0 'MPU-401 (UART) 0-0' client 72: 'Rawmidi 1 - ESS ES1978 (Maestro 2E) MPU-401' [type=kernel] 0 'ESS ES1978 (Maestro 2E) MPU-401' client 80: 'Virtual Raw MIDI 2-0' [type=kernel] 0 'VirMIDI 2-0 ' client 81: 'Virtual Raw MIDI 2-1' [type=kernel] 0 'VirMIDI 2-1 ' client 82: 'Virtual Raw MIDI 2-2' [type=kernel] 0 'VirMIDI 2-2 ' client 83: 'Virtual Raw MIDI 2-3' [type=kernel] 0 'VirMIDI 2-3 '

[linux-audio-user] [ANN] AlsaModularSynth 1.5.9

by Matthias Nagorni

Hello, AlsaModularSynth 1.5.9 is available from alsamodular.sf.net New Features: - The Midi input module (MCV) has now a Trigger Output which enables Multi-Triggering (Thanks to Fons Adriaensen for the patch). To enable Multi-Triggering, just connect the trigger output of the MCV to the retrigger input of the ENV. - New module "Stereo Mixer". With this module you can mix several patches and switch between them. Signal paths that are muted are not processed. (Again: Thanks to Fons Adriaensen for suggesting this module). - New example patches demonstrate the MCP-Plugins by Fons Adriaensen. Take the time to try these plugins. They add many new sounds to AlsaModularSynth and vastly improve it's sound quality. I especially recommend example_basic_vcf_reverb_moogfilter_env.ams and example_phaser.ams (don't miss to play with the ModWheel) Have fun !

When running the default source install, wx-config is installed in /usr/local/bin - maybe that's not in your path?

[linux-audio-user] command line cdload

by Tim

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I've mapped my multimedia keys to play CDs with commands from cdtool. The only thing thats missing is a load command. There seems to be no opposite to cdeject. The only way I can close the tray is with cdrecord -load dev=0,0,0 Is there anything simpler or do I simply have too much time on my hands?

[linux-audio-user] OT: Minidisc help needed

by Joe Hartley

Well, I did something amazingly stupid - I erased the MiniDisc that I had recorded my son's band's performace on. (3 songs: an original, Blitzkreig Bop, and Anarchy in the UK - I'm so proud!!) I'm looking for someone who has a MiniDisc recorder capable of performing the trick of rewriting the table of contents as listed here: http://www.minidisc.org/cloning_procedure.html Help me go from zero to hero with my son!! If you've got a deck listed on that site, please drop me a line - you'll have my extreme gratitude. -- ====================================================================== Joe Hartley - UNIX/network Consultant - jh(a)brainiac.com Without deviation from the norm, "progress" is not possible. - FZappa

[linux-audio-user] audio cdrom permissions

by derek holzer

i've been having a bit of trouble with playing and ripping CDs, maybe someone here can help? i'm running Debian on a laptop, and as root i don't have any serious problems doing either, but as a user it becomes a bit wierd... let me explain... as user, i am in groups cdrom and disk. i have set permissions as follows: in /dev: lr-xr-xr-x 1 root root 13 May 18 17:31 cdrom -> cdroms/cdrom0 drwxr-xr-x 1 root root 0 Jan 1 1970 cdroms in /dev/cdroms lr-xr-xr-x 1 root root 34 Jan 1 1970 cdrom0 -> ../scsi/host1/bus0/target0/lun0/cd in /dev/scsi/host1/bus0/target0/lun0/ brw-rw-rw- 1 root cdrom 11, 0 Jan 1 1970 cd i have none of these other cdrom devices listed in /dev: /dev/hdc /dev/sr0 /dec/scd0 but my drive appears to be ATAPI with SCSI emulation. i have added the following to my /etc/lilo.conf to reflect this: append="hdc=ide-scsi" although commenting this out doesn't seem to do much. i can rip CDs as a user with Grip, but RipperX tells me i need permission to access the CD drive [cannot open cdrom drive]. i can play CD audio with Alsaplayer, but not with XMMS. likewise, xfreecd doesn't find the drive, but workman does. very inconsistant! running cdparanoia -vQ as user gives the following: Checking /dev/cdrom for cdrom... Testing /dev/cdrom for cooked ioctl() interface /dev/scsi/host1/bus0/target0/lun0/cd is not a cooked ioctl CDROM. Testing /dev/cdrom for SCSI interface No generic SCSI device found to match CDROM device /dev/scsi/host1/bus0/target0/lun0/cd it seems that there are still some permissions to change somewhere, but i can't for the life of me figure out where! what have i missed? thanks, derek

[linux-audio-user] [Fwd: [Ardour-users] pitch raise?]

by Patrick Shirkey

I see a similar problem while using the pitch scaler. I thought it might have been the harmonics of the tone I was using and the fact I had it echoing before scaling. But it only worked at the lowest settings moving any of the faders more than a small bit caused it to max out and kill all the audio in tX until I turned it down again. -- Patrick Shirkey - Boost Hardware Ltd. Http://www.boosthardware.com Http://www.djcj.org - The Linux Audio Users guide ======================================== Being on stage with the band in front of crowds shouting, "Get off! No! We want normal music!", I think that was more like acting than anything I've ever done. Goldie, 8 Nov, 2002 The Scotsman

Considering your critisism I realise that you are probably right about alot of usability issues, I've used it too long, I no longer think about the quirks it has ;). I understand though that it can be a major obstacles for new users (together with lacking documentation). I'd be very happy for any suggestions you might have about usability enhancement (or anything else for that matter). You mentioned for instance keyboard shortcuts and customizability which is duly noted (and master tempo which is a long standing usability problem). You mentioned trouble to do certain things, do you remember if there where other "things" than those mentioned? If you have more, please send it along. Of course that goes for others also!
