You can record the midi stream with something like arecordmidi. This  
will need to be quantized before denemo will import this. Denemo only  
supports import of midi that has a single melodic line on each staff/ 
track. Of those midi files types that it does it does have support for  
tuplets if any kind. Denemo supports tupplets but importmidi does not  
yet have that feature. Importmidi lacks support for other things as  
well like time signature changes.

Opening the midi file will work if it is very simple.

No. I thought of creating one but did not know where I wanted to  
procede. I had four possible ideas on improving this:
1) write a utility that converts midi to musicxml. The advantage of  
this would be that more people may be I terested in helping. Then give  
denemo support for importing musicxml. This probably won't be very  
hard since the denemo format is xml.

2) midi2denemo only denemo users would be I terested in this

3) rewrite import midi in scheme reducing the size of the denemo  
binary, working at a high level, and not having to complie anything.

4). Improve import midi. This currently lacks many features. Having  
worked with denemo this seems a little easier than it once felt.

Lilypond has a utilty written in python that converts midi to  
lilypond. This utility would be a great place to start because it does  
have a quantized built into it.

I doubt it would create problems. You can take a denemo file and add  
white space to see if it loads okay.

Let us know what you decide to do.
