The new IK Multimedia Uno Pro lineup has two versions- the Synth Pro features a 37-note Fatar keyboard and pitch/mod wheels while the Synth Pro Desktop version has capacitance-sensing keys and pitch/mod touchstrips. But the connectivity and sound engines for each model are the same.
The analog synth engines in both the Uno Pro models each have three analogue oscillators and lots of modulation possibilities. Each Oscillator allows variable waveshape and pulse width modulation. You can have the oscillators interact with each other via hard-sync, FM, and ring modulation. There is also a white noise oscillator.
Compared to the original Uno Synth, the Pro versions have been improved by a new SSI 2/4-pole low-pass filter and you can even use the two filters in series or parallel and with invertible phase, giving you a total of 24 possible filter modes.
