 Thanks for the feedback Robin. I'll look into those suggestions. Sorry
 about the sound issues, I really have no idea what I'm doing. Python seems
 sketchy when it comes to audio and I don't know any other languages, nor do
 I know anything low-level regarding audio. I'm very new to this. I made RASP
 dependent on libsnack2-alsa because that's what works for me and I don't
 know how to make it work otherwise. * shrugs *

I found gstreamer to be pretty easy to use in python.

Here's a very thorough tutorial:

 Hello, this is my first communication here.
 
 I'm a former Windows user and recent Linux convert. After switching, I
 noticed some utilities I regularly used in music production were missing
 from the major repositories, simple things like tap-temp, delay/Hz
 calculator, and note-to-frequency conversion. I was looking for an
 excuse to learn programming so I started working on this music toolkit
 of mine. It's all the stuff I need for making music calculations all in
 one place (like a producer's Swiss Army knife). Maybe you have a use for
 it too? Includes: tap-tempo, delay/Hz calculator, song time calculator,
 note-to-frequency converter, simple frequency generator, and a metronome.

Hi Brian,

Welcome to the fabulous world of linux-audio, where we all do those
calculations in our head :)

More seriously: RASP is a cool app and most welcome addition!

I just tried 'rasp-2.5.py' and it does not make any sound (neither via
ALSA nor JACK) -- probably a tkSnack on debian issue, though. Anyway,
the calculators are already bound to come in handy at some point! Thanks.

One small suggestion: please put the source into a sub-folder so that
the .tar.gz unzips to rasp-2.5/rasp.py, rasp-2.5/rasp_icon.svg

Cheers!
robin

PS. As for a metronome, you may want to check out
http://das.nasophon.de/klick/ -- it supports click tracks and integrates
perfectly in a jack-studio setup. It is packaged for most distributions:
klick and its GUI: gtklick.

IOError: [..] cannot access /dev/sound/dsp

Debian ships  version of libsnack2 (used by tkSnack) with OSS backend,
because the ALSA backend of libsnack2 is apparently broken:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=431341

Well that explains the no-sound problem, then. OSS is not supported on
this system of mine. ..and some OSS wrappers show up as /dev/dsp - not
/dev/sound/dsp

Nevermind,
robin
