Tricks for Indian Music

[sridharar]

Thanks Jimsweb for the note and also the link.

I am attaching a piece where I tried to take advantage of the annoying resonance as part of the music.

For the single sine oscillator case are you able to confirm that it works for equi-tempered as well as other scales. (snip) ...

Tested with quarter tone scales and still works properly using Sine Wave with no filtering.

Hello Rick

I did some more simple experiments.

Tried using tempered scale, built in instruments, and no transpose.

Thought may be it was using tempered scale distances and ignoring custom scales. But the behavior seems to be orthogonal to this.

Whenever Portamento is ON - the glide does not seem to land on the right note/tone. It does not matter what the first key and second key is. Thought closer the keys are, less pronounced abherration would be. But is not the case.

Of course distortion is more perceptible on 2nd and 3nd octave areas - and less so on the 4th and higher (think proportionate distortions are smaller given the higher frequencies).

Also eager to know your opinion based on your discerning ear. what the "tonal difference" is -- shift in pitch or resonance or filter - or some other envelope parameter.

Regards Sri.

Sri. Bhai,

I think the pitch is ON ... it's the filtering effects that give the note an entirely different timbre. The fact that I was able to create a new sound with a simple sine wave with no filtering that did not exhibit the 'effect' leads me to beleive it is not necessarily a systemic issue (i.e. not a bug) but a consequence of filtering effects over the time of a note. Maybe the 'release' parameter of the sound is modified by the portamento function. Also have you made sure that if you have a multi-oscillator sound that all the layers have the portamento parameter set appropriately ??? Have you tried creating a new sound with a single Violin oscillator with no filters programmed? I'll try doing that later today.

Off topic but you might find it useful in a way.


Here's an Indian midi pop song that I programmed for a couple few years ago. It was recorded with PA800 sounds at the time, so you guys might have to tweak/change the sounds. It's possible it will playback just fine.

Here's the download link:

Hello Rick

Thanks for confirming that PItch is not the issue - and it might be to do with filter. That is one down and so good.

Sure I can create another violin - single oscillator without any effects and check. With the built-in violin, I was originally suspecting the sample itself may have the issue - and now feels that we can rule that out as well - as the problem is across the board.

Impressive always your ability to include Hindi words.

Thanks again for helping here - as I have been struggling to play good raga alapanas - where, as you know only Taanpura is involved and one cannot hide tonal issues which even a casual listener can easily discern.

Regards Sri.
I have to learn how to get Devanagari scripts inserted liek you do.

Thanks for posting your composition. Sounds like a nice Bollywood number. Do What instruments are you using? Not sure whether they will port over to PA600. Can you export the sounds for importing in PA600?

Thanks Sri.

Hi Sri...I do not remember what song this was. They sent me a Youtube link and I created a midi program based on the youtube version.

so you tried it and it did not playback ok on PA600?

[sridharar]

Hello Sam

I just played it as a midi file on windows media player. I can certainly play it on Korg PA600 and would not be an issue. But I thought you were pointing to some instruments from PA800 which you had used and I should try. So the reason for the question about getting those sounds. Did I miss a link for downloading that PA800 set?

Regards Sri.

No, I wouldn't use windows media player. You must use a korg PA keyboard.

There's no need for a particular SET. I've used factory voices only. That's why I think it should playback without problems.
