If you're an Optigan owner, you may be interested to see this teaser for the soon to be released Optigan Sitar & Tabla sound disc.
This footage comes from the recording session, featuring Rama Douglas on sitar and Justin DeHart on tabla.
According to the developers:
The new Optigan disc will feature a variety of different sitar riffs (and possibly some harmonium notes on part of the keyboard). The chord buttons will have 15 different tabla loops, and the SFX tabs will have tamboura drones and other effects.
