Sound comparison with JRaaga/JFugue

Show and Tell
#1

Attached are
Same notes (pitch,duration), same soundfont and same instrument - played from SCAMP and JRaaga / JFugue
SCAMP Recording:

JRaaga Recording:

Wondering why difference
One thing that is in JRaaga - is each note has attack of 120 (out of 127) and a release of 30 out of 127
Gotta keep trying

#2

Hmm… not sure what’s going on here. What code are you using to generate the scamp recording?

#3

Both audio were recorded using my phone - let each software to play the notes. If that is what you meant.

#4

No, I mean what is the code? (What do the play_note calls look like?) It sounds to me like the pitches are being read differently.

Both codes play the same “pitch numbers” -
here is the western notes played by JRaaga

You are right - though western notes are same - I do see some pitch wheel events:PW() in above output - which means they are “fractional notes”
I have to read JFugue manual to understand :PW(8151) to :PW(8182) is what fractional note of F4
Second thing that is different is “duration factor”
In JFugue - default note is a “quarter note” - but when I played with duration of 0.25 in SCAMP is was too short. So I kept as default=1.0

SCAMP Western Notes (Veena) - here there are no fractional notes.
While coding now in python - I thought since carnatic notes in the soundfont are already aligned to western midi notes - no need for fractional notes.

n’ ScampInstrument(Veena) Veena 88.5 0.5
s’ ScampInstrument(Veena) Veena 78.0 1.0

Anyway - I have to go back and compare my java code and python code - whether I use same “math”
Because - in carnatic there is also what is called “base note” represented by “S” (which is not nesame as western note C) for each instrument - to align with the instrument’s harmonics and the vocalist.

Marc,
I think I see exact one octave of difference between JFugue and SCAMP.
Please let me know if you feel the same.
Java Code:

import org.jfugue.player.Player;

public class JFugueDemo {
public static void main(String[] args) {
Player player = new Player();
String notes = "V0 T60 I[Piano] C5 “;// C#5 D5 D#5 E5 F5 F#5 G5 G#5 A5 A#5 B5”;
player.play(notes);
}
}

And the SCAMP Code

from scamp import *
s = Session()
s.tempo = 60
durn = 1.0
piano = s.new_part(“piano”)
start = 72
end = 73
for note in range(start,end):
piano.play_note(note,1.0,durn)
exit()

Notice the octave difference. Now change SCAMP note to 60 they would sound the same
Not being a musician myself - not sure my observation is right.

JFugue jar can be downloaded from

Marc,
Sorry for too many posts. I think I now know the reason.
I had originally used JFugue-4 and then switched to latest JFugue-5. It appears JFugue-4 used the octave range as -1 to 9 while JFugue-5 changed it to 0-10 scale.
http://www.jfugue.org/articles/differences.html
Which means C5 in JFugue-5 will play one octave higher than same C5 in JFugue-4
Hmmm. Now I have to figure out the implications of this to my pyrhon and java code
