Juno-G?

I would definitely recommend you a Juno-G or (maybe even better for gigging) the new 76-key Juno Stage. They both have 128 voice polyphony and 6 effects processors, and a lot of great sounds inside.

Can you use an expression pedal? i.e. for Wah-Wah on Clav or Volume on an Organ

Yes, you can assign the foot expression pedal to almost anything, from volume or wah-wah to leslie or phaser speed etc.

How editable are the Patches? i.e. how many effects can you add? can you edit attack time and release?

The patches are 100% editable. And the Junos have the same sound engine with the Fantom-X, so there are lots of things you can do out of raw materials inside the board. It's a full-blown synthesizer.

What is the Organ section like? how can it compare to using drawbars on a B3 for instance? or is it just a few different Organ setups?

You can't compare it to a real B3 or even an emulator, but in general the Juno can do this and even much more variety of organs due to it's synthesis and effects capabilities. The four tones of the patch can work as four drawbars, for example.

Thankyou very much! Especially for the heads up about the Juno Stage!

There is a Juno-Stage Forum that you may wish to browse. We will know much more when Roland posts the Juno-Stage Owner's Manual. I am sure there will be a spirited discussion when the manual is available!

Let me add Dom's usual comment on the G.

If you are the one lugging it around to shows you will love how light the keyboard is!! I use my Juno G and D's exclusively now. They are both wonderfully light.

As for B3 growly sound, the D has a better one built into it than any I have found for the G, but there are TONS of organ sounds out there for the G.

The G sounds great, BTW, don't want to detract from that..

Hi everyone,

Sorry to change the topic, but I need advice on getting new techno sounds for my Juno-G. Im quite new to synths.

If you are a gigging musician..no offense for roland ok...get a Korg X50..It is handy good quality of sound also,and easy to navigate or change patches...

The Juno-G is a mixed bag. First, let's say that after one year and half it's still a very good machine with very musical sounds and a comprehensive and powerful feature set. I have it in my setup and I'm still satisfied with it.
It's very light and compact, and this means it's very easy to carry around to gigs and rehearsals. It has almost everything you need: powerful synthesis engine, powerful performance mode, sequencer, arpeggiator, sampler, easy GUI and big display, expandable with srx cards.
On the other hand, it has some weaknesses. The keyboard has only 61 keys and is not a professional-level keyboards, with its smaller keys that are a bit difficult to use to play complex parts. The piano sound is not that great, and its 64 megabytes of samples are now a bit too few compared to products like the Yamaha MO6 or the new Korg M50 (not the X50, which in my opinion is also a bit outdated and built like a toy). This weaknesses make the Juno-G not very suitable as the first and only instrument in your setup. The Juno Stage would be much better if you don't need workstation features like the sequencer, because it has 76 standard-sized keys and a much better piano sound, while still being a light keyboard (10 kg).
In this moment, I also think the M50 is probably the best low budget-low weight workstation around. It is really a step ahead its competitors from Roland and Yamaha in the price range. I would seriously consider the M50 instead of the Juno-G.
With the sounds you need, I would also consider the Nord Electro 3. It has wonderful acoustic pianos, wonderful electric pianos and clavinets, a wonderful organ emulation (it is a full-featured hammond clone, which means you will be able to play the organ with results you will never get on a standard sample-based workstation), comes in a 73 keys version all made of metal and yet it weighs only 9.1 kilos. I have a Nord Electro 2 and it's built like a rock. All settings and effect can be applied in real time with the knobs on the panel, so putting a wha-wha on a clavinet or a tremolo on a rhodes is just a matter of pressing a key. It's a different concept, where you don't rely on presets anymore but rather you work as you did on the original instruments. What's more, the NE3 can use additional high quality samples from Clavia like strings and orchestral sounds. Its only problem is that it is not multitimbral, so you can play only one of these sounds at a time. And these are the only sounds you get (no synths, no editable patches).
As a general-purpose workstation for the maximum flexibility and sound quality, in this moment I would buy a Korg M50. Or, if you need a performance-oriented instrument with a good keyboard to be the main instrument in your setup (76 keys are really needed if you want to do serious piano playing or use some split points), the Juno Stage.
