Although my provider's spam filter still blocks linux audio mails, I'm
happy to announce my novation launchpad midi driver.
It is not a driver in the common sense, but a user space usb application
which offers a midi out and in to write and receive launchpad midi messages.
On my distribution(gentoo) I needed to add myself to the usb group to
run this application.
I know the dependencies are quite fat(boost) but this driver is part of
my sequencer application, and I just want to give launchpad owners the
possibility to use their pad.
boost >= 1.41 (need threads, signals2, foreach)
To build the whole stuff you need cmake(>=2.6).
$ tar -xjf launchpadd-0.1.tar.bz2
$ sudo make install
To uninstall use :
$ xargs rm < install_manifest.txt
I would be very happy to get some feedback from the users and developers.
Coming from the Java world this is my first(finished) project in c++ and c.
And I didn't know anything about USB before...
So if there is a developer who has got a good knowledge of c/c++ or usb
interrupt transfers it would be great if he could have a look at the
code, especially the method handleWriteTransfer in LaunchpadImpl(.cpp)
is a point where I'm not that sure about the interrupt handling(although
it works as it is right now).
