And I think that this fits the bill pretty well for me. I have, on occasion used Indian instrumentation in pieces, so I can see that it could come in handy I suppose. It also seems reasonably priced although I think that you need to buy the bulk of the instruments via IAP.
Anyway, you make up your own mind. Here are the details …
Add up to 79* perfectly sampled virtual Indian instruments to your iPad’s sequencer! SwarPlug is an Audio Unit Extension that will load in AUv3 compatible hosts like Garageband, Cubasis, etc… as additional voices that can be played through the keyboard, in new loops created from scratch through your MIDI editor, or by using the thousands of MIDI loops included in the plugin.
*This app initially only includes the Tabla instrument, but you can download any additional voice you like through In App Purchasing.
