Video from a test session with Sergio Koval playing his Yamaha CS-80 at Synthoma studio.

The test is a chorus comparison with the CS-80 built-in chorus, a Digitech multieffect chorus, and the élkorus analog bbd chorus.

Now the CS-80 can do a very nice strings, not only brasses!! More info about élkorus and synthoma in general, at www.synthoma.net
