For sell a Rare piece of gear.
I made a demo of this Synth in action: check it on the gallery.

Ideal for those who want the amazing sound of Siel Opera 6/Dk600 but need space in studio.
Or for who have already a Siel Opera 6/Dk600 and want to play with a monster doubled voices (12 voices x 4DCOs) turning your Siel Opera in a polytimbric synth with split mode.

Comes with TAUNTEK upgrade installed on it which gives all these new features:
1) all controllers, except for the two wheels, of the expander can be controlled via midi (CC)
2) omniMode
3) all sounds can be loaded in one go via midi.

After the purchase i ll send you also the software editors for Max for live, Reaktor from NI, an environment for Logic and a patch for the BCR2000 from Behringer

w Case

For every kind of question feel free to write me. I m also available for a demo videocall
