There’s lot of info on Gearslutz about using the H9000, i wrote a review there and there’s a review on Sound on Sound

Loving my H9000 – we’re waiting for some missing Algos from H8000 and some new modules

I’ve never owned a Harmoniser before but I’ve found the H9000 very easy to use – I don’t use the screen much, in fact I leave it off and it just lights up when i use it and times out quick. Using Emote makes it simple

Vsig is great – found it ok to learn Vsig and have made a couple of Algo which sound great..it’s hard work but rewarding
