Roland U-20, Roland U-220

The U-20 is nothing special. It is a digital synthesizer that uses ROM samples of pianos, brass, strings, bass, drums, etc. However it is built for professional use and is truly a quality instrument, even though its sounds may seem like dated-eighties synth pop cheese. It's got nice piano sounds, but they're not the real thing.

The U-20 features 6 part multitimbrality with a 7th drum part, plus 2 direct outputs and 2 stereo outputs. The 30 note polyphony helps if you take advantage of this synths multitimbrality for creating entire performances and ensembles. Digital reverb, chorus and delay effects liven up your sounds. Editing is simple, but there are no filters. With several performance features, the U-20 has a full 61 note keyboard with velocity and aftertouch. There's an on-board arpeggiator, a chord-memory feature and the U-20 accepts Roland SNU-110 sound library cards. It has been used by Prodigy and Astral Projection.

The Roland U-220 (pictured above) is simply a rack-mount version of the U-20. It has all the same sound

Roland JUNO-G Workstation Keyboard

Is the JUNO back? Maybe. The JUNO-G is a full-sized Workstation Keyboard from Roland featuring much of Roland's current state-of-the-art synthesis technologies, putting a studio's worth of sound, sequencing, and audio recording into one complete instrument. It shares the same high-powered processor as Roland's Fantom-X series but packages it in a synth that looks very reminiscent of the old JUNO-synths, and also puts many of the controls at your finger tips. Not to mention, considering what you get, the JUNO-G is a very affordable synth.

Roland's powerful Fantom-X sound engine offers up to 128 voices of polyphony (a quantum leap from the 6 voices offered by the original JUNOs). The sounds of the Fantom-X engine are typical of Roland's most current sonic palette. This is no analog wannabe synth, its sounds are purely digital although many analog modeled sounds are available. You also get Roland's 88-note multi-sampled grand piano, and a wide range of sounds that span from classical to cutting-edge. You can further expand your JUNO-G sound library with one of Roland's optional SRX expansion boards.

True to its workstation capability, the JUNO-G features an onboard audio/MIDI recorder for programming and recording your own music sequences. There is a 16-part MIDI sequencer with dedicated transport controls and mixer. There are also four companion stereo audio tracks which allow you to lay down live parts from external audio sources (like vocals, guitar parts, etc.). Both the MIDI sequencing and audio recording memory is ample, allowing room for plenty of recorded ideas, performances, songs and parts.

The JUNO-G has a fairly user-friendly interface featuring a very large back-lit LCD display (not a touch screen), clearly labeled buttons, six knobs to modify sounds, five sliders for the audio section, a data wheel, a D-Beam controller, and a pitch/mod lever. Additional performance controls and features include the on-board Arpeggiator, Chord Memory and built-in multi-effects. The JUNO-G really has everything you need to perform, compose, record and create your music. Of course it offers MIDI in/out as well as USB connectivity for interfacing with computers (all MIDI communications can be handled over USB, which can also be used to send and receive WAV/AIF files and patch data). There's also a PC Card slot (which accepts CompactFlash or SmartMedia cards via adapter) for external memory storage.
