[CM] Problem while recording from midi keyboard

[Thanassis Zervopoulos]

problems appear when
I play a looping chord with the left hand like 'la do mi.....la do
mi......etc' and with the right hand I hold a note
It seems that midi-message receive a midi-note-on from right hand and
doesn't let left hand to pass midi massages to midi event.....any
suggestions?

I'm sorry for sending the same e-mail, but there was no response on the
previous one and I don't know if this recording-problem is general problem
or
happens only to me...

Also I've tried your example below,but it gives an error message:
I only have common music dictionary, so I couldn't find
the function midi-message->midi-event....where can I find a complete
tutorial for cm

Thanx in advance and I appreciate your help very much
