Musicians, artists, and performers looking for a compact analog synthesizer will be thrilled by the IK Multimedia UNO Synth Pro Desktop, an ultralightweight analog powerhouse with a capacitive-touch keyboard, onboard FX, sequencer, arpeggiator, and comprehensive connectivity, including low-noise 1/4" main outputs and CV/Gate I/O.

The UNO Synth Pro builds upon the success of the original UNO synth, but ups the ante with three analog oscillators, which offer continuously variable waveshape, including pulse-width modulation. Oscillators can be hard synced for more harmonically complex tones, and oscillator FM (frequency modulation) lets you shape everything from bell-like sounds to screaming industrial tones.

The UNO Synth Pro includes the original 2-pole OTA multimode filter and adds a new 2/4-pole SSI low-pass filter with self-oscillation. The dual filters can be used in series or parallel with invertible phase for a total of 24 filter combinations. The instrument also includes two full ADSR envelope generators (filter and amplifier), with both available as sources to modulate numerous parameters via the 16-slot modulation matrix. Modulate oscillator pitch and waveshape to LFO speed or even other envelope stages. Two LFOs are also included for simple vibrato and tremolo effects to complex modulations including audio-rate FM.

The UNO Synth Pro offers 256 user-editable presets and features an onboard 64-step sequencer which can not only step record and real-time record note info, but can also record automation of up to 40 parameters for intricate, evolving soundscapes. A 10-mode arpeggiator makes it easy to create intricate patterns. The UNO Synth Pro Desktop ships with a micro-USB to USB cable.

Related Questions and Answers

Q: 1. I already use the irig pre. Recording eats my phone battery quickly. Thus I have it charging while Im using it, with a brick battery. Can I do the same with the duo?

A: You can use the optional PSU to power iRig Pro Duo, but it will not charge your device while in use. Alternatively you can use iRig Powerbridge to charge your device while you use iRig Pro Duo, but the Pro Duo would still need batteries.If you're currently using iRig Pre, you might consider the iRig Pro I/O. This is only one channel, not two like Pro Duo, but it does have an optional PSU that will both power the iRig Pro I/O and charge your iOS device at the same time.

Q: 2. The specs say "comes with USB cable." Is that the older USB-A connector, or USB-A useable with the new MacBook Pros?

A: The included cable is a Mini-DIN to USB Type-A cable for connection to Mac/PC.If you would like to use a USB-C adapter, this will work fine. We also offer a Mini-DIN to USB-C cable here. https://www.ikmultimedia.com/products/?A=usb-c-to-mini-din-cable

Q: 3. Can this be externally powered from an A/C source?

A: Yes, as long as it is 9VDC with a positive sleeve and at least 500mA.

Q: 4. Hello BH To use with iPhone/videorecording connect to microphone/XLR - what is best choice: IK Multimedia iRig Pro or IK Multimedia iRig Pre HD?

A: iRig Pro and Pro I/O only output processed audio, meaning the app you're using to record must support real-time monitoring for you to be able to listen to the audio while recording. iRig Pre HD allows you to switch to direct monitoring so you can hear the audio directly, which is useful with apps that don't support monitoring. Many video and streaming apps don't support this - the built-in recorder, Facebook Live, Instagram, for example. So this is worth considering.In terms of sound quality the two are very similar.

Q: 5. Will this work on my MacBook Air (13-inch, Early 2015) and recording to garage band?

A: Hey Paul, Yes, the iRig Pro I/O will be Mac compatible and work with software like GarageBand.

Q: 6. If this irig pro I/o plugs directly into the lightning port, how can I charge my phone? Belkins lightning splitter only supports 24/48 audio. Can still use this with my mini audio jack on my iPhone 6?

A: There's an optional power supply that can run Pro I/O and charge your device at the same time.When you connect this the headphone jack on the iPhone 6 won't work, but there's a headphone jack on the Pro I/O itself you can plug into instead.

Q: 7. if I want to livestream with my iphone 7plus on facebook, using external mic and irig pro I can control sound for livestream and it would work seamlessly?

A: You can control the input gain on the microphone which would affect the volume in Facebook Live but it's not a pure volume control. But it should still work fine, I know many people using Pro I/O for Facebook streaming with no issues.
