Arranger & Player

The KETRON SD7 Arranger keyboard is the product of a long, passionate development process and in-depth musical research. Finally, both worlds of a professional class arranger and performance keyboard have been merged like never before into one incredible machine.
Whether you want to play music with friends as a DJ, do karaoke style, simply play something creative and inspiring or write your own music – the SD7 will assist you in all scenarios with its comprehensive, innovative features and professional sound.
These include new sound generation, a huge sound library, revolutionary Style Modelling system of Styles and beats, Multimedia capability achieved with up to date technology all of which make the Ketron SD7 keyboard a powerful and indispensable tool for contemporary and modern musical entertainment.

Styles on the Ketron SD7 Arranger Keyboard

The Ketron SD7 has an innovative, intelligent and professional arranger section with 260 styles.
These cover musical genres and rhythms which are being requested in the modern live entertainment world.
These styles utilise an impressive library of more than 300 Latin Percussion Grooves and 200 Audio Drums. The Audio Drums are perfectly synchronised with the internal Midi clock, a wide tolerance range is possible even at high tempo changes (up to – / + 30% of the original BPM). Each style has four variations A, B, C and D, plus 4 Fill Ins, 4 Breaks, 3 Intros, 3 Endings, ‘To End’ and other live control functions such as Re-intro, -Key Key Start Stop, Count In, Restart. In addition, 5 User buttons are provided which can be programmed for additional functions.

The accompaniment section is made up of an Audio Drum track, bass track, 5 tracks of chord sections which incorporate musical harmonies and can be varied, and 2 manual/Lower voices. 3 orchestral VARIATIONS are present which can easily be turned on or off to obtain either more simplified or complex arrangements, as well as variable guitar tones within guitar accompaniment tracks. 4 lead voices can automatically be assigned to the right (lead voice) and it is possible to match them to the four variations – ABCD of each style.

The operating system of this keyboard is very easy and intuitive, thanks to the new and large touch screen. It allows you, for an example, to quickly modify the voices, volumes and effects of each style & pattern within the Arranger section on the fly, and to then save the changes as a new USER STYLE. This helps create a custom style library which doesn’t affect the factory styles. With MY LIST, the user can further consolidate and store 64 favourite styles in one location – making it easy to instantly search for and use your best styles.

Much attention has been paid to orchestral harmonies especially wind instruments, which are now re-created with separate harmonic lines to obtain more realistic sounds within this section. The Unplugged group offers more styles with very basic arrangements which use just a Guitar or Piano voices with percussion, an ideal acoustic environment for improvisations or other musicians to play along with.

Style Modelling on the Ketron SD7 Keyboard

The STYLE modelling tool is a powerful and unique feature now available on the Ketron SD7 Keyboard (the only Arranger Keyboard to offer such within this price point). This allows for the quick selection and usage of hundreds of Audio Drums, Grooves, Base lines, Piano, Guitar andOrchestral tracks for any style – accessed via the internal library of the keyboard. These tracks can be assigned to different sections of a Style, thus allowing you to build a completely new style with hardly any style programming background needed.

Creating a new custom arrangement simply by using Style Modelling is a really simple and stimulating experience. The selection of the arrangement parts can be performed while the keyboard is playing therefore Style Modelling can automatically be a studio engineer’s dream come true with the capability to quickly create or alter styles on the fly. You can find assortments and combinations of unimaginable sound, between different musical genres, or interchanging different sounds with perfect rhythmic synchronisation all the time.

These include Latin Grooves, bass lines or any arrangements. Once the assignment of the new parts has been completed, the new style can now be saved as a User Style.

New Play Modes on the Ketron SD7 Arranger Keyboard

The ketron SD7 keyboard has been designed to be configured for use in different ways. If you are a pianist, you can use the PIANIST mode to play as though you were playing a real piano while still being able to control the arranger. If you prefer to play the bass manually (Manual Bass mode) while still using the Arranger, the BASSIST mode is available – a mode which utilizes sophisticated logic to control harmonies performed with both hands in real time.
Beyond the simple Midi set up, a new dedicated menu has been developed for the ACCORDION and ORGAN players.

CLASSIC mode: – Grants the accordionist total manual control over the Ketron SD7’s voice sections. The accordionist can program complete manual orchestrations with 2 voices allocated to the left/chord and 3 voices to the right and lead voice, and all these set ups can be stored in a Song setting/Registration for instant recall on stage.

STYLE mode: – On the contrary, this mode now utilises the Arranger which is controlled by the Left Hand. With the Bass To Chord, the accordionist can also define the tones of the chords automatically, which are normally not available in the normal style technique.

The accordionist can then express themselves better with new forms of expression in the context of light music and jazz.
There is also a new ORGAN mode to control the bass either manually or automatically by using the optional Midi pedal board (Mod. KETRON PCM 8) which allows for performance the way Organists are accustomed to.


The new Sound generation featured in the KETRON SD7 keyboard offers 543 orchestral sounds of GM structure divided into 4 banks of KETRON’S “Best Natural Sounds” including the new Stereo Grand Piano, Sax and Brass sections … new guitar and bass all multi-layered, plus new and professional Pads, Strings, Synth, Electric Piano and Accordion sounds using stereo and MultiVoice technology.

368 VOICES in 12 voice groups all with sophisticated EDITS consisting of up to 3 layered sounds (plus the ability to add 2nd Voice to any lead voice), and functions of Velocity switch, Duet, Trio, Steel, Harmony, all which can be edited and saved into the USER VOICE section. Many controls are available in real time such as Double Down-Up, Harmony, EFX, after touch and Portamento and a VOICE LIST section is also provided where the user can store 32 favourite Voice for quick recall and use in live situations.
48 acoustic and electric DRUM KITS and a new special STEREO KIT are constantly monitored by a special tool called LIVE Modeling which randomly utilizes multiple samplesof instruments such as Snare, Rim Shot, Claps, Snap within loops to simulate the feel of the live performance of a real drummer … as a drummer doesn’t hit his snare the same way twice! In other words it will feel like a live drummer is performing with you.

Searching for and identifying VOICES has been made much easier due to the new graphic images featured on the touch screen.
These images associate each instrument with its orchestral image.

Ram Sounds on the Ketron SD7 Arranger Keyboard

Ketron SD7 Keyboard Panel


Registrations allows you to take a snap-shot and store the general panel settings and current conditions of the “SD7” including all parameters and functions. 4 storage Banks each capable of holding 1024 Registrations are available. These Registrations and Song settings are easily controlled on the touch screen and can be quickly recalled using the numeric keypad or externally via MIDI.

The SD7 is equipped with a dual professional player capable of playing back MP3 type files, MIDI (different formats with lyrics), WAV, FLV, CDG, MP4, AVI, M4A, JPG, PDF, and TXT. The device provides automatic functions such as Cross Fade, (fading from one song to another), LEAD MUTE (excluding the lead voice from an audio track or lead track from a Midi file) and Alphabetical or Numerical SEARCHING of files within the disk.

You can connect a video projector directly to the DVI connector on the unit. Navigation is achieved by using the Alpha dial and scrolling through files directly on the touch screen.
You can create custom PLAYLISTS and also have the ability to quickly access your favourite files, thanks to … MY FOLDER.
The JUKE BOX page is also provided for quicker access to songs and a new DJ menu now gives you access to a dual virtual turn-table from which you can apply special effects to the music you’re playing such as Tap Tempo effects, Pitch, Cut Off, Resonance, Tempo, Brake and Back Spin.

SYNC mode / NEXT allows you to accurately synchronise the beginning of the song (Midi,MP3 or WAV), in perfect sync with the one currently being played in order to create well synchronised real-time medleys. Furthermore, the Player is capable of utilising Midi files which have already been enhanced with WAV or MP3 tracks – all perfectly synchronised together.
The new function RESTYLE DRUM allows you to easily replace the monotonous drum track of a traditional MIDI file with any of the Audio Drums available for the styles.

The utilisation of VIDEOS in today’s musical performances has become increasingly important, so the KETRON SD7 keyboard is also up to date in that regard, allowing you to view and display on an external monitor (DVI) movies and musical videos of all kinds. While the video is playing, it is still possible to continue performing with MIDI files or MP3 or Styles simultaneously.
This keyboard also has other important innovations such as the utilisation and control of PDF files with the ability to now display graphic files (e.g. musical scores) on the displayed or monitor with internal functions available such as scroll, zoom, etc.
An AUDIO MULTITRACK that allows the playback of multiple wave files within and audio project.

The multi track audio is presented as an excellent alternative to traditional MP3 and WAV files during professional PLAYBACK, offering the opportunity to work on each of the five tracks in a selective manner which leads to less volume sliders on the panel.
A track can also be assigned to the CLICK Metronomic (or to an individual output) that can be sent via external audio through the headphone output (Aux).



The keyboard has a new AUDIO and MIDI recording function and menu. It is possible to memorise brief patterns in PHRASE mode (also available while using the Arranger) then later, loop it during playback or record complete parts in SONG mode.
The audio track is recorded as a stereo WAV file which can further be modified by inserting start and end points, as well as the output level.

Brightness control (conveniently placed in the back of the keyboard) allows you adjust the brightness of the colour display which is especially useful in dark or sunny conditions.

Our Thoughts

A review of the Used Ketron SD7 Arranger Keyboard (Stock ID: #7234) by Michael Wooldridge

Today I am here to look at the Ketron SD7 keyboard. I’m not sure where to begin with the SD7, as there are so many aspects for us to talk about. The way it works is that you select the tune you want to play on the keyboard menu and the music appears on the screen and the sounds and the style are set up for you and you just play. This works really well, and it is especially nice being a wide screen, as it means that you can see two pages of music at a time.

The song titles appear as a list but you can also put them into folders, in the same way that you save files on a computer in folders, which means you can keep all items from one book together, or perhaps all settings in one style together, or whatever filing logic suits you, perhaps alphabetically. There are four registrations for each song. At the moment, the saved registrations link to PDF files, so as you add your own you will probably scan in the music to get the PDF.

A quicker and much used way to capture music is to just take a photo of it, using a digital camera or smartphone, but at the moment you cannot link registrations to the jpeg files that this method usually produces. You can though, have them show on screen, so your music is there.

Moving to the SD7 keyboard itself, it is a really nice 5-octave keyboard with a super 7” colour touch-screen, which is one of the best laid out screens I’ve seen, as it is really, really clear and seems to work in a nice logical way. I must mention that the screen doesn’t tilt at all, because it doesn’t need to! The image is designed so that it is really clear to see from any and every angle.

The keys are described as lightly weighted, have both initial and after-touch, and are nice to play. In keeping with the display images, the instrument has a really clean look about it, with the buttons and sliders all clearly labelled. It has in-built speakers, four speakers set behind two panels to each end of the keyboard and delivering a good sound. I think you know that whilst there are arguments for and against having speakers built in, personally I prefer having them there.

I must do the facts and figures before I forget! The SD7 is 115cm wide, 39cm deep and 12.5cm high (without the music desk). It weighs 15kg (33lbs). It seems to me that the SD7 is a keyboard that is designed really for playing live, it isn’t so much about pre-setting lots of sounds in advance. Having a touch-screen that has been well designed makes it really easy to use for selecting voices and styles and then there are sliders for balancing all of the volumes in a quick and easy way.

The voices are in family groups and selecting a family brings up screens of options. For example, selecting Guitars will produce options including Nylon, Country, Jazz, Vintage, Django and Jazz Octave. It’s the same sort of thing for each family, so go into the Strings and the options become the nice, soft, sustained Bond Strings, Octave Strings, a delicate Violin, Tzivago (think Somewhere My Love with Strings and Mandolin), and, if played in the higher octaves, even some very effective Bagpipes!

A rather lovely but slightly random voice is called Harp Gliss, which plays the most beautiful arpeggios but only in a limited range of keys. The voicing is all very good but perhaps some other highlights include the superb Contralto Saxophone, a Clarinet which sounds very like the great Acker Bilk, some nice Pan Pipes in a voice called Andes, and there’s even an Alpen Duo, which gives a Clarinet playing the top note and a Trombone underneath.

Some sounds are RAM Sounds. Whilst all of the general voices are good, there are 46 even higher quality sounds, including pianos, solo sounds and the rotary organ sounds. Whilst there aren’t all that many of them, what drawbar combinations there are sound really good with a good reproduction of the rotary speaker effect. The voices include a superb 16’ & 1’ jazz setting and another classic jazz using 16’ and 5 1/3’. There are also a couple of good church organs.

Whilst thinking about organ sounds, it’s a good time to mention that it is all ready for you to connect a pedalboard so you can have full control and not have to be entirely reliant upon styles to play. Of course, the pedals can control bass sounds suitable for orchestral and jazz playing, not just organ sounds.

Layering two voices together works in a slightly different way on a Ketron to other makes of keyboard, but is straightforward and, because there are proper volume sliders, it is really easy to balance the second voice. Moving on to the backing Styles, these really impressed me in two ways, both of which make them stand out from some others makers. First of all, whilst they have plenty of parts to make up each Style, they seem to be useful for playing many different songs from within each genre, rather than being really song specific. The other thing is that the Styles sound very live, much helped by the Live Drums, and very like hearing a band play rather than a keyboard playing, which is excellent.

There are so many Styles that it is hard to pick and choose but here are a few of those I enjoyed.

Each Style has four preset voice settings set to go with it. People who know me well tend to complain about my handwriting, as I write (and draw) very small and no-one much apart from me can read it, but that’s fine by me! If I am having to write things for people to read then I try to write more slowly, which puts them in with a chance of deciphering it, or if adjudicating at a Musical Festival, where written comments can be of huge importance, I tend to use a fountain pen, which makes me even more legible! Anyway, the point of telling you this is that amongst my dozen or so A4 pages of notes about the Ketron, there is one word I confess that I myself cannot read, and we’ve come it to it now! There is a Style called British something. I’m fairly sure I’ve noted it as British Tune, but that just seems a little unlikely, which is why I’m doubting myself! Anyway, it is a really good style for tunes like Let It Be, that gentle but rhythmic sound that is so lovely. The voices set with it are Piano, Strings, Jazz Organ and Electric Piano.

That said, I may or may not have the next one correct, as I was never good at foreign languages! It is called Spatzen Beat and is a style reminiscent perhaps of the James Last Orchestra playing A Little Peace, and the sounds to go with it are Piano, Trumpet, Organ and Piano, all of which work well. Disco 70s brings up a great Wah Guitar sound and Old Blues is a really enjoyable 12/8 rhythm with Piano, Harmonica, Clean Guitar and Brass. The Jive is a really lively and exciting live sounding style with Piano, Organ, Sax and Brass for the tune. Motown gives a really driving stomp rhythm, very reminiscent of the period and great for songs like Knock On Wood, and the Ragtime Piano is just right with its Piano, Honky-Tonk Piano, Clarinet and Muted Trumpet for the melody.

It is very simple to customise Styles using the Style View, in which you can see all parts of the existing Style and really easily change the instrumentation by just touching the voice you want to change and then putting a different voice in it. You can then save this as your own Style. You can also create loads of new Styles using the Style modelling, which allows you to change the feel of Styles and to mix and match the various segments which make up the patterns; it’s hard to explain so you probably need to try it to make sense of it and how easy it is to use.

There is a Style Convertor so you can import your favourites from earlier Ketron products. We are used to products these days having thousands and thousands of preset registrations but this is not the case on the Ketron SD7. It does have the four preset registrations to go with each and every Style but after that it is really a case of doing your own thing, but remember, as I said earlier, it really is designed to be used as a live instrument and changes are really easy. You can save preset sounds, so you can save your favourite settings.
