ALSA autoconnect

2009-12-23T08:34:19Z

Suppose you wanted a soft-synth to be instantly playable at startup
(given the option: '--autoconnect') then what would be the ALSA
functions for:

1) Saving the current "live" connection at exit (if any.)
2) Restoring the above (saved information.)

Re: jcgui-0.4 initial release

Hi Hermann :)

GTK isn't my friend today. Building the GUI failed :(. Any hints?
I like Fons' jconv a lot, but because of the missing GUI I prefer to use
linuxDSP SR-2A. When I saw the screenshots of the GUI you made I was
happy, but now ...

OT:

A note to the coders. We users most times prefer dummy proved
configurations. It's not always so easy to solve an issue like it was in
this case.

For zita-resampler libs configuration is fine by default, but for the
app I got

$ make
g++ -O3 -Wall -MMD -MP -DVERSION=\"0.2.0\" -c -o resample.o resample.cc
g++ -L/usr/local/lib64 -o resample resample.o -lzita-resampler -lsndfile
-lpthread -lrt
/usr/bin/ld: cannot find -lzita-resampler
collect2: ld returned 1 exit status
make: *** [resample] Error 1

Dunno what to do, but I guess this is not needed for jconv ;).

Jconv's make configuration is fine :).

Cheers,
Ralf

my impression has been that the best musicians always take risks ....
which pay off, sometimes!

Re: hosting of jpmidi

2009-12-23T07:42:05Z

Hi, I'm the author of jpmidi.  I just saw this thread in the list after replying to an off-list email from David.

JPmidi went off the web in October when Yahoo shut the Geocities service down.  I had no idea there was any interest in jpmidi because David's email was the very first I received since its initial release several years ago.  Because I thought there wasn't any interest, I never took the trouble to put it up on sourceforge or some other open source hosting site.  I can do that if you think it would be worth the effort.
