Playing it like an organ is what it's designed for, but, it has to have more than "organ" voices...that's the idea behind this instrument, is it not? To give the organ player more options?
I think what Jazzhooves referred to may have meant that it should be played with your limbs and perhaps some rhythm backing but not a full arranger backing. I see great benefits to both methods of play, and I enjoy them both. The recent convention on European organ playing style is to not have a full arranger behind you. You also need a pedalboard.
At350c seems to be a good fit for people who want an arranger at times, and an organ (like I described above) some of the time too. For people who just want a hammond sound to fit in with a band, and perhaps some other quality sampled sounds to throw in too, it is also a good choice due to it's portability and dual manual setup. I can see it may do well for Roland, and I am quite keen to get stuck in about it.
I think the cello is a Supernatural sound from recollection. Active Expression is a term used in different ways on different devices. I first was aware of it with the VR760 where you could use your expression pedal to swell an additional tone through the organ or the organ through the other tone, or both crossing paths at the same time.
However on the Atelier it seems to mean something different. Your expression pedal adds more expression to the sound, not just a volume change. I'm not too sure how to describe it really, it's the first time I have had an Atelier in the store, so I have a lot to learn until I am an oracle of all it's capabilities! I did try it with an EV7 though and it adds 'something.'
The only "negativity" in these posts seems to have been introduced by Fran with his accusatory tone regarding my query...I'm merely asking the same questions any customer would ask.
