Yes, true. Dikshitar's handling is a bit different from the modern renditions of Thyagaraja's compositions, so I've put it in another thread.
Dikshitar has composed only a single kriti in this rAgA - sarasvati chAyA tarangiNi - so here it goes

Apologies. Couldn't find any other recordings that were clear enough. These are the only ones out there.
Dikshitar uses SRGM and SRM, RGMG, MGRGR, and RMGR and even a very nalinakAnt-ish RP. He also uses PDN, DNDP, and PDNS also. There is also a chittaswaram for it. A tinge of kEdAragauLa / nArayaNagauLa is sensed in it as a result of using these phrases, especially the heavy use of GR.
Dikshitar would have not needed harikAmbhoji really with a raga like this at his disposal.
But then -- there's an SSP version out there as well : https://www.youtube.com/watch?v=x9TlzSL4bBo - while it is mostly plain, it is identical to the modern version overall, including the chittaswaram, and some of the gamakas used in it are still there in modern version.
This is a good example of a modernized kriti that has grown in detail over a long period of time, but hasn't been retuned.
