The sound engine in both cases is exactly the same. You have three oscillators with wave shaping controls and options for saw, triangle and pulse with pulse width modulation. There are also hardware sync, ring modulation, and frequency modulation (FM) options to achieve harsher, more metallic sounds from the synth.
There are 256 preset locations to save your patches, a 10-mode arpeggiator as well as a 64-step sequencer with automation for 80 parameters to lay out your tracks, plus a 16-slot modulation matrix, two LFOs and two envelopes for everything. create subtle vibrato with extremely changing tones and evolving pads.
IK Multimedia kept the original two-pole multimode filter from the original Uno, but also added a 2/4-pole self-oscillating LP SSI 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 taken from the original Uno. The other three blocks can be filled with a combination of the 12 built-in digital effects covering reverb, delay and modulation.
There’s also plenty of connectivity here too – balanced stereo outputs, headphone output, 5-pin DIN MIDI in and out, assignable USB MIDI plus CV, and gate connections for connection to modular and semi-modular hardware. There’s even an audio input in case you want to run other instruments through the filter and effects.
The Uno Synth Pro isn’t as cheap as the original, but it looks like it offers a bit for the price. Especially the $ 400 desktop model. Of course, a full judgment will have to wait until we can try one ourselves.
The Uno Synth Pro and Pro Desktop are now available for pre-order and are expected to ship in the first quarter of this year.
