MIDI input is currently only implemented for JACK MIDI. But adding MIDI 
input support to the ALSA backend is trivial, so I'll get to it right 
away. Thanks for the reminder :)

When running as a JACK client, Denemo has no control over the sample 
rate and period size. Only JACK itself actually talks to the audio 
hardware, and these values are configured in JACK's parameters. Have you 
tried experimenting with different settings in QjackCtl?

For the PortAudio backend, sample rate and period size will probably be 
back as configuration options in the Denemo preferences dialog.
