- Title: Korg i5S
-
-
-
- -----------------------------------------------------------------------------
-
- Korg's phenomenally successful M1 synth is still in use by bands
- worldwide. Their O1/W series continues to grace many a recording; the
- Wavestation too. The company's latest X5 range is aimed at small studios
- and synth beginners; however, the Korg name has been noticeably absent
- from keyboard enthusiasts' living rooms. The more recent i series has
- edged that way... now, with the i5S, has it finally arrived?
-
- Overview
-
- The overall appearance of the i5S is more traditional than that of the
- previous i-series keyboards, with style and program names printed on the
- case for the first time and small pictures of drums above the keys, too.
- The keyboard itself is a touch-sensitive, slightly stiff, 61-key model,
- and to its left is the usual pitch-bend wheel plus a single button that
- replaces the usual modulation wheel - holding this down applies a fixed
- amount of vibrato to the current melody sound, and this can be changed
- between styles. Although not as flexible as a full mod wheel would be,
- this illustrates the design concept of the i5S perfectly: once it's set
- up to your liking, subsequent performances require the minimum of
- effort.
-
- Moving up the unit, there's a set of dedicated function buttons, rows of
- number keys for selecting instruments and styles, and a small LCD. Sadly,
- instead of proper volume sliders you have to make do with individual Volume
- Up and Volume Down buttons for the melody, accompaniment, bass, percussion
- and so on.
-
- This makes fiddling with the exact balance trickier, especially as you
- can't immediately see the current volume of each part - once again, the
- approach is that you do a minimal amount of work to set the style up,
- and forget about it from then on. But the small LCD is more of a
- problem. In contrast with the latest big-screen Yamaha and Technics
- offerings, the i5S has a 20-column, two-row character display, with only
- a few general controls (cursor movement, value up/down) for changing
- values. You'll find yourself pressing the Next Page and Previous Page
- buttons until they wear out as you customise the styles to your liking,
- thumbing through the manual all the time: what does 'BSequenc MID PD'
- mean, anyway?
-
- However, there's also much to commend in the panel design of the i5S.
- Pressing the Volume Up and Volume Down buttons for a particular part
- together mutes the part in question - very handy. There's a convenient
- Tap Tempo button, which sets the rhythm to play at whatever speed you
- beat; separate octave and note transposition controls; and a few
- dedicated function buttons such as the Sustain button, a boon to anyone
- playing the i5S without a footpedal. Best of all, there are separate
- rows of number keys for selecting styles and instruments, with a 10 Lock
- button which lets you select a set of eight styles (for example, all the
- waltzes), and hop from one to another with one key-press. The current
- style is usually shown on the LCD, with the instrument name flashing up
- as you type in a new number.
-
- Look carefully under the keyboard, and you'll find a discreetly
- camouflaged disk drive. It's almost as if, in an attempt to design a
- welcoming home keyboard, Korg hope that you won't notice it. It's a
- useful feature, however, because not only does it let you play Standard
- MIDI Files with the i5S, you can also load extra styles: American,
- European and Japanese disks are supplied with the machine, and it's 100%
- compatible with its predecessor, the i4S - for which there are over 25
- disks available.
-
- How it plays
-
- Enough of the controls; it's time to put the i5S to work. The keyboard
- boots up with the 8-Beat 1 style selected, a sturdy workhorse of a
- rhythm - all you need to do is press Start, and spin out a piano melody
- with your right hand, the left hand playing the chords you want to hear
- in the accompaniment. No matter how eccentric your chord sequence, the
- Korg can cope with it; its intelligence in determining what chord you've
- played is little short of miraculous, as the LCD informs you that the
- five random notes you just played together were, in fact, the diminished
- chord of P minor with a raised ninth and a side order of fries. If
- you've never played a home keyboard before, you'll need to get used to
- playing each chord slightly ahead of the beat, so that the accompaniment
- can pick up on it in time (the i5S may be exceedingly clever, but it's
- not psychic - although, come the i6S...). This skill is easily learnt -
- it's just a shame that a couple of styles, notably Country1, are more
- sensitive to your timing than others, with any great variation from a
- strict rhythm producing an unholy mess in the accompaniment.
-
- That said, the i5S possesses a lot of useful features to improve the
- sound of your performance: an automatic harmonisation feature, for
- example, adds chords to your right-hand part based on what you're
- playing with the left hand.
-
- You can even tell it whereabouts on the keyboard you'll be playing
- chords: either the lower or upper half, defined by the one user-chosen
- split point, or over the entire keyboard. This feature can be a boon
- when you're playing pieces intended for the piano, but it's a shame that
- there's no way of combining the best parts of this and the normal
- sensing methods, with the left hand taking priority if two chords are
- played at once.
-
- Alternatively, you can recover the whole keyboard for your chosen melody
- instrument, and select chords using the numeric buttons usually
- dedicated to calling up styles and sounds. If your performance doesn't
- require any mid-song changes in rhythm, this feature, although tricky to
- get the hang of, can prove exceptionally useful - but for those who
- think that reaching across this far is all too much effort, there's a
- backing sequence mode for recording a set of chord changes to be
- replayed on demand. It would be misleading to compare this with the
- fully-blown sequencers found on workstations at this price, but the
- feature set is surprisingly comprehensive. Despite rudimentary editing
- features, made all the more difficult by the cramped display, there are
- quantise, bounce-down, and 'save as Standard MIDI File' features in
- here; the save option enabling you to build up a library of chord
- sequences without having to reprogram the keyboard every time. Chords
- can be recorded as you play or entered in step time, and the 10 backing
- sequences can be chained in any order you like - perfect for a
- verse-chorus-verse structure.
-
- How it sounds
-
- You could easily keep an audience satisfied for half an hour with a
- virtuoso performance based on the i5S's 8-Beat rhythm, but there are 127
- other presets to explore - plus the 64 in the user bank. In fact, there
- are four variations for each style, making 768 in total. Add to this a
- couple of fill buttons plus an intro and ending for each style (often
- the most imaginative parts of the arrangement), and there should be an
- accompaniment for most purposes even without recourse to the many
- available style disks. Unsurprisingly, you can't edit the styles or
- program new ones - as we've seen, Korg's intended market for the i5S
- consists of people who want to do as little setting up and editing with
- their keyboard as possible.
-
- The 128 preset styles begin with a comprehensive selection of 8-beat and
- 16-beat rhythms, with some rather schmaltzy rock and pop ballad styles.
- Waltz aficionados are also well catered for, with the jazz variant
- particularly good: the faster waltzes tend to be slightly
- over-orchestrated, but a little twiddling with the volume of each part
- can lessen this effect. One occasionally bizarre aspect of the presets
- is the default instrument assigned to each style; in the main, they're
- eminently sensible, but a harpsichord with a chugging 8-beat rhythm?
- Again, scrolling through a few LCD pages can fix this problem.
- Traditional home keyboard styles such as bossa novas and sambas are
- supplied in abundance. There's a great Latin rhythm, a couple of
- practical 'party polkas', and a Slow Swing which could have come
- straight out of your local Pizza Express. It's worth straying a little
- from the norm, though, as some of the best styles are slightly more
- leftfield than these: PosoDoble1 (whatever that means) is exceptionally
- well done, with the East European Gipsy1 also deserving to be singled
- out.
