I wish Arturia would pay more attention to the user interface of their synths. This is very important to electronic music composers that like to create their own sounds (like me!). Hardware analogue synths are WAY easier to program, even taking MIDI controllers into consideration. A lot of analogue synth composers don't like soft synths for this reason alone, not the sound! Just read some interviews with VInce Clarke and Jean-Michel Jarre...
Arturia synthesizers have beautiful looks but not so practical interfaces. There's no generic MIDI controller that can map all the controllers of complicated synths like the Moog Modular. Also, you always end up of with controls on weird locations on the MIDI controller. In the end, you always end up using the mouse (or finger on the iPad) to create sounds with software synths. To make it worse, a lot of controls on Arturia synths have a really small area to click which is really annoying. Korg is the only company I've seen to came up with an awesome solution by building a dedicated controller for their MS-20 emulation.
This is the first time Arturia really improved the interface of their synths. The iPad version of the Minimoog interface is a huge improvement over the original one. Even on the small iPad screen, all the knobs and buttons are bigger than the desktop version. They're way easier to access and manipulate. You can tap two fingers and control two parameters at the same time. Take that mouse! The screen MODE is also a smart way to show more (less essential?) controls. I would go even further by having an option, for those with MIDI controllers, to hide the virtual keyboard and use the space for more controls. The Minimoog is a simple synth, this will be very important on more complicated synths like the 2600.
Good job and please improve the interfaces on the desktop synths too!
