[LAU] alsa midi to jack midi

hello, I've been looking at ingen ( http://drobilla.net/software/ingen/ ). Had some problems getting it to build, but the trick turns out to be to install liblo and libsoup bfore you configure the build. It's a really nice bit of software - a GUI modular synth that lets you design and save simple patches which can then be used as building blocks for more complex ones. The main problem I'm having with it so far is that it doesn't seem to understand alsa midi - only jack midi. This is difficult as I don't have or know of any midi programs (particularly a virtual keyboard) which produce jack midi signals. Does anyone know of an easy way to convert alsa midi into jack midi and vice versa? andy
