A lot of devices and software systems (of the commercial type at least)
seem to have a tap tempo system where two taps are all that is needed to
set the tempo of an effect or sequence.
I would really like to be able to tap something to cause hydrogen to
start in sync with a live performer. Tempo tap seems to be missing from
the hydrogen feature set though.
But then it occured to me that perhaps there is a program out that that
can act as a Alsa or Jack midi source clock that gets it's tempo from
tapping (either a key or a midi foot pedel)? Has anyone seen such a
thing?

I've been wanting the same thing. Maybe a simple JACK transport
master that, given the number of beats per bar, waits for one bar's
worth of taps (from some given input device) and starts the transport
at that BPM. Like when Dee Dee Ramone yells "1, 2, 3, 4!"
Maybe I'll try to write such a program, and name it DeeDee.

This will be a very intersting thing ... as for lilve playing... and
very important also -- and i think the code should be written as an
extension to JACK(jackd deamon) so all the application that connect to
JAck will straight away inherit that global BPM set by jack(as the case
may be or set by an application which has this TAP in function for BPM
check)

I don't want to reveal any big secret, but I can say that the next
release of Freewheeling will be able to do such a thing ;)

Two tabs normally aren't enough IMO, however that really is easy to do
in, guess it: Pd. Attached is the naive idiom which just spits out the
time interval between two events. Uwing [mavg] - which is an object to
do a moving average, it's part of Pd's zexy externals - you can do a
simple averaging, and for more advanced tempo finders, check out the
objects in the "maxlib" Pd-externals-library and [borax].
Using the [ctlout] or [noteout] object you can generate midi messages
(there are more midi objects in Pd, too.)

Heh, I have an old tossed-off python script that may be handy too.
Just run it from the command line, tap any key any number of times,
hit "q" when you're done and it prints estimated BPM.
But it's ancient and uses a deprecated library module;
so it only works in Python < 2.4.

Hi Paul,
nice :) I just tried it ... if you replace all instances of TERMIOS with
termios (and then remove the redundant import), it works in python 2.4.
cheers,
Conrad.

And while we're at it, here's a handy small GUI program I've written a
while ago which serves the same purpose. Requires PyGTK.

it's not perfect, but you can press the backslash key to tap the tempo in
hydrogen.
