The sound engine in both is exactly the same. You have three oscillators with ripple controls and options for saw, triangle and pulse with pulse width modulation. There are also options for hard-sync, ring modulation and FM (frequency modulation) to obtain harder, metallic sounds from the synthesizer.
There are 256 predefined slots to save your patches, a 10-mode arpeggiator, as well as a 64-step sequencer with 80-parameter automation to establish your ranges, plus a 16-slot modulation matrix, two LFOs and two envelopes to create everything from subtle vibrato to tones that change wildly and evolving pads.
IK Multimedia kept the original two-pole multimode filter from the original Uno, but also added a 2/4 pole SSI self-oscillating LP filter. And you can use both filters simultaneously in series or in parallel.
Oh, and there is an effects section with four blocks, one of which is dedicated to the analog overdrive circuit, also inherited from the original Uno. The other three blocks can be filled with a combination of the 12 integrated digital effects that cover reverb, delay and modulation.
There’s also a lot of connectivity here – balanced stereo outputs, headphone output, 5-pin MIDI DIN input and output, USB MIDI plus assignable CV and gate connections for connecting to modular and semi-modular equipment. There is even an audio input, in case you want to play other instruments through the filter and effects.
The Uno Synth Pro is not as cheap as the original, but it seems to be offering a good price. Especially the $ 400 table model. Of course, the full trial will have to wait until we can try one.
Uno Synth Pro and Pro Desktop are now available for pre-order and should be shipped in the first quarter of this year.
