Hi, I am quite new to Csound and I am having a little issue with a project I am trying to develop. I thought this might be the right place to ask for a little help. Please let me know if this is cool.
In a few words, I would like to fill a few arrays with data coming from a MIDI stream (being it a live performance on a keyboard or information coming from a MIDI file). Then, I am planning to analyze this data and translate it into performance data of some kind. Actually, I do not need to "record" the whole performance, just data regarding a certain time window (the last bar for example).
To begin with, I have started from a very simple program that reads a MIDI file and prints note-on and note-off events to the output console.
This i what I wrote:




-F test.mid




sr = 44100
ksmps = 32
nchnls = 2
0dbfs = 1

massign 0, 1	; make sure that all channels
pgmassign 0, 1	; and programs are assigned to test instr

instr 1
  
  kstatus, kchan, kdata1, kdata2 midiin
  
  if (kstatus == 144) then
    knoteontime times
    printks "status= %d\\n",0, kstatus
    printks "note = %d\\n",0, kdata1
    printks "at: %f\\n",0, knoteontime
  elseif (kstatus == 128) then
    knoteofftime times
    printks "status= %d\\n",0, kstatus
    printks "note = %d\\n",0, kdata1
    printks "at: %f\\n",0, knoteofftime 
  endif
  
endin




i 1 0 10
e




(I rearranged the example reported in the opcode help of "midiin" to my needs.)
It seems to work quite well, except for the fact that it actually does not print the very first note-on message and the very last note-off message, and in the case of a MIDI file containing a single note nothing gets printed.
Could you please advise me about what could be the problem here? It seems to me that the problem is not in the printing, as I have also tried storing note numbers in a variable and the same problem seems to persist.
Hope you can help me find a solution! 

Cheers

Andrea

Also could you provide your test.mid?

I think the midi triggering needs to be disabled with

That is not what I get in CsoundQt using test2.mid. I just do not get any message printed.

Using test.mid I get everything printed except for the very first note-on and the very last note-off.

Trying to use massign 0, 0 did not help, unfortunately.

Maybe this issue has to do with CsoundQt?

I think the problem is that your CSD is not terminated properly (you have  
 instead of  ). If you put the backslash, it
should work (I only noticed it when I tried your example and noticed instr 1 was not being
instantiated by the score).

It works, thanks a lot!

I was not expecting something like this could be the bug because I thought Csound would have displayed some kind of warning.

Anyways, thanks again and I am sorry it was such a dumb question in the end!

I think the problem is that your CSD is not terminated properly (you have
<CsoundSynthesizer> instead of  </CsoundSynthesizer>). If you put the backslash, it
should work (I only noticed it when I tried your example and noticed instr 1 was not being
instantiated by the score).
