This is a known ALSA problem, you can work around it by writing to a
separate virmidi port from the sequencer and connecting the two ports
with 'dd'. For example, if virmidi is card #1, and the sequencer writes
to virmidi 1-1 while Csound reads from 1-0, try running this command
in the background:

dd if=/dev/snd/midiC1D1 of=/dev/snd/midiC1D0 bs=1

Hi,
Or use the Midi Through port instead of vir-midi.

Cheers,
Andres

hi there,

those of you who read musicians magazines have probably read ads from 
David L Burge about his perfect pitch training courses.

I bought his tapes years ago & it makes sense to me. But you need to be 
two people to play notes at random from the piano. in short.

here is a csound orc+sco that is an attempt to do what the first 
chapters of the perfect pitch course does. it plays notes at random 
from a diminished chord - f sharp, e flat, a and c. without the need of 
another (interested) person. ;-)

the first lesson is to just listen to an f sharp on the piano and get 
acquainted with its characteristics. then after a while you play an e 
flat and notice the difference. not in timbre, but in "pitch color". as 
Dr Burge calls it.

after a week, add an a. another week later, add the c. don't stress the 
brain, please.

when somebody plays the four notes of the diminished chord at random, 
in different octaves, the relative pitch hearing will get confused, and 
the only way you can tell which note it is, is to use your perfect 
pitch abilities.

about the orc -
the line with the variable "ival" is where you specify a table with 
notes - the notes that will chosen by the random generator:
10 - a function table that contains f sharps and e flats, in a few 
different octaves
11 - an f table with f sharps, e flats and a's
12- an f table with f sharps, e flats, a's and c's.

the correct answer is printed. to help you if you are not quite sure 
which note is played. ;-)

the next step would be to add c sharp, e natural, g natural and b flat, 
successively.
and then the remaining four notes.
but I'm not at that stage yet in my perfect pitch training. ;-)

have fun!
;-)

Thanks Peder!

In my youth, I was obsessed with perfect pitch (which a friend of mine had,
but I did not).  I too was sucked into the David Burge tapes but never got
very far with them.

Maybe it's time to give it another try?

I went through the Modus Novus and Modus Vetus methods, they were very 
helpful, especially Modus Novus. IIRC the preface to Modus Novus had 
some comments regarding the difficulties someone with perfect pitch 
might have with the method.

The free-as-in-libre Solfege is also a fine learning aid.

Best,

dp

come on, it's not a curse! and from what I've heard, perfect pitch 
hearing is not an absolute.

since my own experience of it is limited, I'm not gonna argue about it .

I hear relative pitch quite good and I am not planning to lose that 
ability. ;-)

I think it's fun, I let csound play the PerfectPitch file, and then I 
play the notes I hear on guitar. it's good also for hearing which 
octave.

if somebody has any use of the file I posted, please let me know!
