Hi, I know I can use '-n 2' to set the number of periods used by LS and Alsa, but I'm not clear how I set the buffer size in LS. I'd like to run LS with the same buffer sizes that I run GSt under Windows with when doing comparisons between them. Is there a command line option for this? Thanks, Mark |

Yes, but there's no -n switch, actually these are the switches you want:
--numfragments sets the number of audio fragments
--fragmentsize sets the fragment size
and btw there are three new commandline switches:
--instrument index of the instrument in the instrument file if it
contains more than one (default: 0)
--volume sets global volume gain factor (a value > 1.0 means
amplification, a value < 1.0 means attenuation,
default: 0.25)
--inputclient connects to an Alsa sequencer input client on startup
(e.g. 64:0 to connect to a client with ID 64 and port 0)
'linuxsampler --help' for more.

Is there any way yet to query a gig file for how many instruments it contains, and what their names are? None the less, it's great to have this capability. > --volume sets global volume gain factor (a value > 1.0 means > amplification, a value < 1.0 means attenuation, > default: 0.25) Cool. I'll try it out and see what I need to do to be approximately equal to GSt. > --inputclient connects to an Alsa sequencer input client on startup > (e.g. 64:0 to connect to a client with ID 64 and port 0) Thanks! Thanks! Thanks! Thanks! BTW - If I didn't say it, then thanks! > > 'linuxsampler --help' for more. > Will download and build now. Will try out in about 8 hours or so. Cheers, Mark |

At the moment, yes, you can use the one character abbreviation for all available switches at the moment, but this only works as long as it's unique. > > and btw there are three new commandline switches: > > > > --instrument index of the instrument in the instrument file if it > > contains more than one (default: 0) > > Great!!

Not in linuxsampler itself yet, but there are a couple of command line tools in the libgig CVS module: cvs -d:pserver:ano...@cv...:/home/schropp/linuxsampler co libgig (one line of course) To compile: make -f Makefile.cvs && ./configure && make then you can run for example: src/gigdump GIGFILE | less and see all samples, instruments and many, many other informations. It's quite much, so better pipe the output as shown through 'less' or redirect the output to a file. > > --inputclient connects to an Alsa sequencer input client on startup > > (e.g. 64:0 to connect to a client with ID 64 and port > > 0) > > Thanks!

It let's me set strange sizes like 512 bytes.

I have not listened to the actual sound to ensure that it's loading the right instrument. > --volume sets global volume gain factor (a value > 1.0 means > amplification, a value < 1.0 means attenuation, > default: 0.25) Not tested yet - will do this evening when I do the sounds. > --inputclient connects to an Alsa sequencer input client on startup > (e.g. 64:0 to connect to a client with ID 64 and port 0) Tested - kaconnect shows the connection after LS has loaded and the connection goes away when LS is killed. Good work! Thanks! Cheers, Mark |
