The key point of the discussion is that Carnatic Ga3 is totally different from Keyboard Major 3rd. Let's first actually hear the difference before debating on the use of keyboard for carnatic.
Please listen to Ga3 played together with Major 3rd. You can clearly hear the beating due to frequency difference:

Now, let us hear Ga3 and Major 3rd in the context of Sa:

From these recordings, we can understand how vastly different our carnatic Ga3 is from the Major 3rd found on keyboard.

What bad could happen if we continue to train students using keyboard for carnatic?
We can learn from what happened to Hindustani music. The use of harmonium, which is also a Western Equal Tempered keyboard, has caused permanent changes in shruti ratios of Hindustani music for worse. A study, by J. Serrà et al, concludes Hindustani ratios are skewed towards western equal temperament over the years due to extensive use of Harmonium. Fortunately, Harmomium is limited to devotional music in the south. Thus Carnatic music still retains its pure ratios.
Take a look at this study for details: "
Assessing the Tuning of Sung Indian Classical Music." by J. Serrà, G. K. Koduri, M. Miron, and X. Serra. International Society of Music Information Retrieval Conference (ISMIR), Oct. 24-28, 2011, Miami (USA).

Sri. Akella Mallikarjuna Sharma, We know you as a modernist who is open to technological innovations for the improvement of carnatic music and its teaching. It is impressive to hear about your innovative, highly configurable, custom made shruti box, modifications you have brought to violin tuning peg to ease gamakam playing, etc. We understand even you had to resort to suggesting western keyboard because there were no better alternatives until recently. We need not bet on western, made-in-china keyboards for the betterment of our music as they are created without any consideration for carnatic music.
We are at a stage where we can make our own technology to match our specific needs. We, at Kuyil, are dedicated to bring mobile apps designed for carnatic music to assist students, teachers and professionals. With your blessings, support and suggestions we can build great apps that carnatic music deserves.

Ga3 is just one example. Most carnatic swara sthanas are considerably different from what is found on keyboards. For example, Ri1 (16/15 ratio) is 11.73 cents higher than on keyboards, Dha2 (5/3 ratio) is 15.64 cents lower, etc. Please refer to Akella garu's posts detailing ratios for each swara sthana in these forums.

Indeed, there is a need for a tool for students to practice independently. Only concern is that a keyboard is not reliable guide for carnatic music. The above study proves that it even damages the sense of swaram gyanam. A better technology, designed exclusively for carnatic music, is what is required. Our own Shruti Carnatic Tuner (android app) is one such effort to provide reliable reference swarams in any kattai / shruti.
Thank you,
Ananth Pattabi
