For a studio based workhorse synth, this is what I want:
Novation virtual analogue Synthesizer engine.
Thunderbolt connection with a logical stereo pair of audio for each of the 16 channels.
USB Connection (optional).
Total integration with the DAW.
High Quality keybed of 61 Keys (like Fatar TP8), with velocity and aftertouch.
Same/similar frontpanel as the Ultranova. But also added assignable RGB pads, faders and knobs for controller functionality.
