Now-a-days the raga we call chalanATa is the 36 sampUrna mela that is quite a different raga. In the meantime, nATa itself has changed to avoid the D3 completely, creating another version that is the modern one that everyone sings. So this chalanATA has made quite a drama by turning from one rAgA into 3 different ragas.
In the early days of the MA, reading the journals would tell you that fixing the lakshanas of nATa must have been quite a debate.
pavanAtmajAgaccha is a well known kriti in Dikshitar's nATa. This version comes pretty close to the SSP one : https://www.youtube.com/watch?v=yOic-yPuzqU - although even this has slightly changed to avoid using D3.
The modern version of the kriti is completely the modern nATa that has no D3 anywhere : https://www.youtube.com/watch?v=AAqICVY8gTI
swAminAtha paripAlaya is also by Dikshitar. Of which GNB's version is the most popular one, but it is in modern nATa with no D3. https://www.youtube.com/watch?v=j1t8BYA7CvQ
Interestingly, Veena Dhanammal's rendition of this kriti would have been near identical to the SSP version, but for a curious tendency to replace every R3 with G3 and make it sound like gambhira nATa at almost every opportunity :-

So this makes a fourth version of nATa??
Just my observation, if you changed all those extra G3's back to R3, it would be the SSP rendition almost exactly.
In the meantime, if Dr. Aravindhan finds out his channel is being linked to a lot in recent days over here, he may grace us with a true SSP version of chalanATa.

I wonder why CM had a superstitious fear of vivAdi so much like a dOsham that the musicians of the times tried to do all this - and one raga became four, not to mention all the other compositions of the Trinity that were stripped of their original vivAdi.
