Well done Zio!

Pros- Probably the most realistic Rhodes Vsti available, sample based or not.
As with all of his releases, the effect is both useable, stable, and accurate- warts and all. Phaser, amp sim and tremolo are nice touches and tailored to the piano sound well.
GUI is logical and well positioned.
Presets: not really applicable here
Customer service: Guido is enthusiastic and passionate about his work, that = good customer service.
Documentation: all CC and midi data is well documented, as well as all knob and switch functions.
Value For money: Not only is the one of the most accurate emulations, its the cheapest of all the "major" players out there.

Cons- not many, I think my only criticism of the sound is that my real rhodes was a bit thicker in the low end: but this was both a blessing and a curse on my rhodes. This is easily cured with some EQ.

This plugin as with the rest of Guido's plugins allowed me to free myself from maintaining my aging rhodes and wurlitzer. I have sold them and use these plugins exclusively.Read Review
