Mx41 have supported alsa and jack since the renaming from Mx4 to mx41. A
limited version have been in circulation in beta since late autumn/early
winter with a warning that specs might change.

Correct. Mx41 will assume you'd like to play right away and grab midi-in
if possible. But if you start, say Rosegarden first, it will be happy to
supply just an Alsa interface. And yes, you can have one application
using the Alsa interface and still play along with it using OSS.

This is strange and definately not intended? Can yo elaborate?

Running from a console, it will complain about not being chmoded root
4711. You can verify in main.c that it will only grab realtime
priveleges and after that resume to the user invoking the synth.

It worries me that you are not able to change parameters. Some of the
sounds in the build directory are playable, but mostly there for me to
decide that I am still within reasonable limits. If you have trouble
editing parameters to your own liking, then something is seriously
wrong!

When I switched to mdk-10.1 I noticed that the threading model had
changed in major way. I did appropiate changes to accomodate for this
but have no practical way of testing for backward compatibility.

What can I say but: Welcome to my nightmare ;)

I use a trackball to point at sliders, and then page up/down/arrowkeys
or even numeric keys for exact value.
