Tricks for Indian Music

Post by sridharar »

I am hoping to spend more time now for getting my Korg PA600 (bought in April) for playing Indian Music.

Thought I will start sharing any ideas/tips I stumble upon for further development through interactions with others.

Some key needs for Indian Classical music (more so for South Indian or Carnatic) are good Violin and Fulte sounds with controllable Portamento and Legato playing (playing multiple notes on the same violin bow or same breath).

You may already know how to accomplish these – but I got my “Ha Ha” earlier this week. Here is what I did. Look forward to your tricks and ideas.

1. Create a new sound – started with just one Oscillator.
2. Used just one layer. The Higher Layer. Set the switch from L->H to 1.
3. I used Sample 119 – straight Violin (no modulations – which I can add via Joy Stick Y+)
4. I set the Legato as OSC trigger to 50 ms and a range of 40 semi tones.
5. I enabled Portamento and fingered mode ** the Key AHA
6. I started with a Portamento time of ~100 ms and still experimenting with it.
7. Used a larger value to address some Ragas that require a smooth glide from lower C to B or Higher C, for example. So needed larger timing.
8. Used this Sound a style – it was important to disable Portamento and enable Mono and Legato for that track.
9. While Playing, whenever I need Portamento, I keep the first key pressed and release it only after pressing the second key.
10. Viola – get the smooth glide happen fully – by holding on the second key.
11. I can also continue and play some other note and get only part of the Portamento glide.
12. A nice way to do things such as going from C to G# via A. (for example)

Enjoy Sri.

Hi Veren

Sorry for the belated reply. Getting back on to this now that the week is over. I will record some and send it it you as a You Tube clip or MP3 file.

Looks like there may be some built-in smarts embedded by Korg, which are not to my liking and are trying to figure as to how to turn them off.

Hi Veren/All

I am stil working on figuring out how various things work and what is the best place/way to get the settings right. Some of the deliberations are:

a) How much of effects to include in the base sound and leave the rest to Style Settings
b) Ditto for the Attack/Release etc settings
c) How exactly scale settings apply. Looks like Global scale has to be set manually. There is no way to set the start ro a different default settings
d) In Song Play mode - how does one control the scale selected?
e) I feel/think that sound produced on E key for example, is different based on whether I am coming from C or from F (even without portamento). Do not yet know what setting is doing this and how to get rid off it.

Tackling a host of such things. Cannot wait to get out of programming mode and enjoy playing.

May be there are other KORG experts who can shed light on some of the items (a) through (e).

Sri.

Veren/All

Here is a YouTube clip of the Audio I created on KORG using the custom Violin sound I created. I can send the complete sound parameters to anyone interested in it.

I am still fighting an issue with a resonance on keys C,C# and D - which I cannot figure out. I think it may be a Filter or Effects issue - but not sure.

Indian Music -- Scale and Portamento Issues

Post by sridharar »

This is just a short note, sharing some new observations. I am planning to call KORG technical support some time soon - as this seems to be an issue with the core software implementation. Probably easily fixed by them - but do not know what a user can do to get around this.

All thoughts are welcome. Especially if you have experienced the problem and/or check out what I am saying here and come to different conclusion and better can point to way to overcome the problem.

Regards Sridhar.

Details:

I have been troubled by basic tonal issues with PA600 ever since i bought the key board almost two years ago. I have been exploring all kinds of settings, and think have finally stumbled on at least one possible issue.

I use a custom scale.
I turn on the Portamento: Select Track -> Easy Edit -> Turn on Portamento and set value to some non zero value, say 25

Now I play D3 followed by C3, and another C3.

The tone for the first C3 does portamento.
It sounds one way when I am holding on C3.
But the tone it ends up being different when I release C3 and play it again.
It sounds quite different. There is an annoying resonance and tonal shift.
Meaning portamento glide is not landing on C3 correctly - just somewhere close but not on it.

Of course this does not happen when the Portamento time is set to zero i.e the portamento is off.

This is a serious problem for Indian Music [and for that matter should be for any music]. We use/need a base tone for 'Sa', that is constantly played by tonal drone in the background, a la Taanpura or Shurthiu Box. Not landing on that Sa simply destroys the essential underpinnings of the music.

I select the C3 key for that, backed by the scale and transpose setting according to the raga and shurthi context. I do not think it is a problem with C3 - but will be for any base note selected (in the custom scale).

This plus the Joy Stick issues (already discussed many times) are basic table stakes for any keyboard worth the name -- not esoteric issues for just Indian music. Of course for Indian music they are so critical.

Korg product management should take note, investigate and fix them asap.

Think it has something to do with the FILTER envelope parameters. Need to play around with it a bit. I can say that I am seeing the same issue you are just using a one oscillator violin. Need to see if sounds with no Filter params give the same effect.

OK - I just tested the portamento with a simple one oscillator sine wave with no filters and it worked perfectly. The note tone after the portamento slide was identical to the re-keyed note.

RE: Portamento and Scale

Post by sridharar »

Hello Rick/GaneshBhai

Happy to see your fast replies. Sincere appreciation for your starting a personal thread of diligence on this. I already feel better that you confirm that there is a problem - and it is just not me perceiving a phantom problem.

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

I had tried various filter and envelope settings, armed with only some minimal understanding of them but did not feel I was making progress. I also tried with built-in sounds instead of the ones I created/edited.

One setting I was suspecting was Global->Tuning-> Transpose Control -> Postion -> [pre/post] settings.

I wonder whether the parameters can be changed through MIDI commands - so they can be applied through a laptop program - making the process systematic, efficient and not labor-intensive. (except for writing that program once of course).

Look forward to your insights and tips as usual.

Regards Sri.
