Usefool tanpura & tabla
Its a very useful app for playing Dilruba or Sitar with a large choice of tanpura and tabla sound. Of course, if you want to listen the good low sound of banya, you have to connect the iPad to external good hi-fi loudspeakers. Its not a cheap app, but it works well and its programmable. I hope it can receive also in the future a constant upgrade process, possibly also with a good harmonium sound.
