#1 midi record problem.

[Anonymous]

I want to write a programm for ear training with your
libary. I have problems with recording events from my
keyboard. For testing I used the demo code on the
midicpp homepage, while I can record events theres
always some kind of null event:

The democode, pressing no keys on the keyboard:

unknown type: *
can't convert this to string yet
unknown type: *
can't convert this to string yet
unknown type: *
can't convert this to string yet
unknown type: *
can't convert this to string yet
unknown type: *
can't convert this to string yet
unknown type: *
can't convert this to string yet
unknown type: *
can't convert this to string yet
unknown type: *
can't convert this to string yet
unknown type: *
can't convert this to string yet
unknown type: *
can't convert this to string yet
unknown type: *
can't convert this to string yet
unknown type: *
can't convert this to string yet
unknown type: *
can't convert this to string yet
unknown type: *
can't convert this to string yet
unknown type: *
can't convert this to string yet
unknown type: *
can't convert this to string yet
unknown type: *
can't convert this to string yet
unknown type: *
can't convert this to string yet
unknown type: *
can't convert this to string yet
unknown type: *
can't convert this to string yet

The * is the value of ev.type, that I hacked into your
code (cout << "unknown type: " << ev.type << endl;)

putting this in an endless loop, and printing the pitch
if theres some gives me something like this:

0unknown type: *
unknown type: *
0unknown type: *
unknown type: *
0unknown type: *
unknown type: *
0unknown type: *
5149unknown type: *
0unknown type: *
4951unknown type: *
0unknown type: *
unknown type: *
0unknown type: *
unknown type: *
0unknown type: *
unknown type: *
0unknown type: *
4345unknown type: *
0unknown type: *
4345unknown type: *
0unknown type: *
unknown type: *
0unknown type: *
unknown type: *
0unknown type: *

While the real events also coming up, there always a
unknown type event, and the messages coming up very
fast and flooding the screen. I have an amd64-gentoo
system and a Roland Juno-D keyboard if that matters.
These unknown type events gives me some troubles, i.e.
they delay my real note events very often.

Some good informations about my system are here:
