Other recent issues: | Roland MC909Sampling GrooveboxPublished in SOS March 2003 Reviews : Sample/Sound/Song Library
Roland's Groovebox concept just seems to keep on grooving. The company launched the first of the family, the MC303, in 1996, which means that the line has now been going for around seven years The Groovebox That Ate Manhattan Less of a Groovebox and almost more of a Groovedesk, the MC909 is an impressive-looking machine. Crammed into that 50x39cm frame are a 64-voice polyphonic, 16-part multitimbral synth engine, a stereo 16-bit sampler, and a comprehensive pattern-based 16-track sequencer with real-time pattern selection options. There are also fully editable effects, a programmable arpeggiator, and many performance/real-time control facilities, including two D-Beam non-contact controllers, and a turntable-emulation slider. Dominating it all is the best LCD we've ever seen on an instrument of this type, offering large, clear graphics and a software-like interface. It all adds up to what is surely one of the most deluxe composition and music-production tools currently on the market, and one which not only interfaces with computers but in many ways does its best to behave like one.
Though robustly built, and quite weighty at around 13lbs (6kg), the 909 has a metal casing that feels a lot less substantial than that of the MC505, with a distinctly 'plasticky' feel to it. The User Interface Before starting on the specifics, it's worth pausing to examine the MC909's user interface. The OS is arranged in pages, such as Pattern Play, Patch Edit and Sample Edit. Pages are selected via dedicated buttons in the various sections of the front-panel, then the 'F' keys under the backlit display access tabbed sub-pages or edit functions. A menu on many pages (accessed via the helpfully labelled Menu button) lists other options. The pages are well laid out and clear, with good graphics. Some pages even resemble software plug-in displays, and there are often choices between list-type and graphic editing of parameters. Once in the right page, you can turn the front-panel controls to alter many on-screen parameters, and use the cursor buttons and value dial to access and adjust parameters that lack a real control. The main adjustable parameters, especially in terms of Patch editing (for example, filter type, cutoff and resonance, and the envelopes), are immediately accessible on the front panel, and may also be used at any time without reference to the screen. The controls and display are very well integrated, and the only thing that would make life even easier is a touch-screen or the ability to connect a mouse. Synthesis Anyone who's owned a Roland synth from the last decade or so will recognise the MC909's sample-based synth engine and its programming system. Specifically, the 909's synth is modelled on that of the newest XV-series instruments.
The heart of the Tone is your choice of one of 693 sampled factory waveforms, or a custom sample, imported or created with the onboard sampler. Actually, two samples can be loaded into a Tone, to accommodate stereo samples, although this reduces polyphony further. Indeed, 64-note polyphony is beginning to look skimpy for a Groovebox whose Patches can contain four Tones, each of which could be stereo. Without delving into the OS, much editing can be undertaken quickly with the front-panel synthesis controls (located to the left of the LCD). Worth noting is that the Tone Switch and Tone Select buttons allow you to tweak all parameters for some or all of the Tones in a Patch (for example, to set the same amplitude envelope for all Tones) or work on individual Tones selectively. The Tone's signal path follows the familiar analogue subtractive synthesis paradigm:
Once Tones have been tweaked, tuned, and panned, and had velocity sensitivity set if required, there are a couple of parameters, related to portamento and mono/poly operation, applicable to an entire Patch. These include 'Unison Fat', which, when Unison mode is engaged, produces effective detuning or harmonising effects that can sound like out-of-tune analogue oscillators beating against each other. Unison pops a Patch into mono mode, even if it was designed to be polyphonic. This is all good stuff, though some may wonder how many more times Roland will be able to recycle and spruce up what is still basically a sample-based synthesis system, complete with short samples and the occasional dead loop. Is it not time to think about some analogue modelling? On the plus side, you can install an SRX-series wave-expansion board in the 909. These boards are still sample-based, but they add a completely new sound set that integrates with the instrument. Available boards at the moment include Concert Piano, Symphonique Strings, Supreme Dance, Complete Orchestra, Ultimate Keys, Dynamic Drum Kits, and World Collection Drums
MC505 users may notice that the 909 Rhythm Sets have fewer voices each 16, one for each of the 'Velocity Pads' so no 'octave-shifting' of the pad bank is needed in order to access the full kit. However, the 909 has 64 factory Rhythm Sets, and room for 128 user Sets, very much in excess of the 505's complement. In addition, any or all sequencer tracks can play back a Rhythm Set (the rhythm track was fixed on the 505). We found the factory kits a little samey and self-consciously 'modern', with no particular subtlety, but given the numerous user memory slots, and the ability to bring in your own samples, it's easy to create custom kits. Sampling Adding sampling to an all-in-one desktop composition tool is a very logical step (previously taken in this market only by Yamaha's RS7000), and creates an even more all-round, self-contained performer. If the 'next generation' adds digital recording tracks (perhaps to SmartMedia card?), the picture will be complete. This is what you see when you're setting up to record a sample. Here you can set input source, auto-trigger level, and pre-sample time for capturing audio that occurs before sampling proper begins. Input level can be monitored via bar-graph and VU-style meters. This device is flexible and thoughtful right from the beginning of the sampling process. There's a surprising range of input choices Automatic and manual sample-initiation options, with control over threshold trigger level, and so on, are provided. One option captures up to one second of audio from before sampling starts, so you should never miss any wanted audio. One very clever trick is 'audio-divide' sampling. With this, you can sample audio that you know has gaps in it
Sample Editing Samples can be looped (with forward and reverse options, but no 'boomerang'), normalised, and truncated at beginning or end. They can also have a tempo assigned to them, which you really should do with rhythmic loops and grooves. You can change a loop's tempo in real time as it plays in a Pattern, and the real-time time-stretch algorithm needs to know the original tempo. Control over the type of time-stretching is also provided, as 10 options offering varying weightings towards slow or rapid phrases. We found that using '5' produced good results with many different samples. There's no way, incidentally, to reverse sample playback.
Another neat facility is 'Combine' almost 'Chop' in reverse. Up to 16 separate samples are welded together, consecutively in linear fashion, to produce a longer sample. Space, in milliseconds or beats, can be inserted during the Combine procedure to help create rhythmic effects. It's a neat way of creating loops and breaks without actually sequencing. At all stages of the sampling process, we were impressed by the display: it's the best we've seen outside sampling software on a computer, with an overview on the top half of the display and a zoomable edit window below. Having said that, we were occasionally bugged by the display lagging slightly behind operations as it redrew. There also is no 'Undo' for sample edits. Samples must be saved before power-down, or you'll never hear them again. On an unexpanded machine with the supplied 16MB Flash sample RAM, this is simple: name the sample, choose a location and save it. Stereo samples need two consecutive memory slots, but with 2000 slots, this shouldn't be a problem. When you power up, you'll need to load into the MC's main working RAM any samples required by Patches or Rhythm Sets you plan to use. Fortunately, this process can be automated: turn 'Sample Default Load' on in the System Menu.
Pattern Creation The 909 takes the familiar pattern-based sequencing approach, and up to 200 user Patterns can be created. These may have up to 16 tracks each (double the MC505's eight) and can be up to 998 bars long, with time signatures ranging from 2/4 to 9/16. Sonic variety may be added by recording synth control and/or mix tweaks in real time over the top of Patterns, which can then be chained into Songs (up to 50 Patterns per Song). This 'automation' data shows up in one of the 909's editing modes and can be edited. Note that you cannot record knob tweaks and mix alterations dynamically over a complete Song, which is arguably when it would be best to do this. A software sequencer-like display and and edit list are available for detailed MIDI event editing in Microscope mode. Note the velocity stalks in the lower portion of the display. The recording process is remarkably straightforward, largely thanks to the LCD. Pressing the Record button accesses the recording Menu, and here you can choose between real-time, standard step-time and classic Roland drum-machine style step-time recording, dubbed TR-Rec. Input for the sequencer can come from an external MIDI keyboard, or from the front-panel row of 16 very good velocity-sensitive pads. These are used to trigger samples, pound out drum parts, and even play chords and riffs with melodic sounds. Their layout isn't ideal for the last purpose, however. Comprehensive input quantising (with percentage weighting options) is available during real-time recording, and Patterns loop while you record different parts into them. Note that you can't have different track lengths within a Pattern. Also, if you've recorded multiple tracks over a repeating loop and you don't like the last track you recorded, using 'Undo' erases the whole recording, because it's treated as one action. Undo in general is not as easy as it could be, because it takes about four button pushes to enable. Trying to Undo in Pattern Edit mode is particularly annoying. Both standard and TR-Rec step-time recording are well implemented, with helpful, clear graphical displays. The only thing we found annoying was the fact that TR-Rec mode can't be used without the rest of the Pattern running, so we usually chose to 'solo' the part being recorded. One more option is available from the Recording page: recording to the Tempo/Mute track. The tempo track is a useful thing, allowing tempo changes to be recorded on the fly (by turning the Value dial, which changes the tempo in the display), or inserted at precise points in the Microscope editor (more on this shortly). This works well. However, what are track mutes, which you'd normally expect to record as part of a normal Pattern, doing on a separate track? We can confirm that if you try to record track mutes as a mix action during recording into a normal Pattern track, they don't record. Another oddity is that although tempo changes can be recorded into Patterns, they can't be recorded into a Song. Moreover, tempo changes in a Pattern aren't recognised once the Pattern joins a Song chain. This is a fairly serious omission: there's no tempo track for a complete Song. If the MC is sync'ed via MIDI, though, it will obviously follow any tempo map on the master device. The straightforward Part mixer on screen. The 909's approach to Pattern editing is an eye-opener, bringing that LCD into play in such a way that you feel as if you're working with a software sequencer. Two editing modes are available: Microscope edit handles individual events, while Pattern Edit addresses multitrack chunks of data of one bar or more. To take these in reverse order, under Pattern Edit bars can be copied or erased, inserted or deleted, and transposition and quantise processes applied. The post-quantise facilities are the same as the input-quantising ones, with the addition of 71 well-designed preset groove-quantise templates. Velocity and note duration for an entire pattern can be changed, data (perhaps overdone controller information) may be thinned, and whole patterns can be shifted forward or backward in time. Usefully, muting tracks before applying many processes causes those tracks to be left unaltered. Microscope editing has been an important part of Roland hardware sequencers since the MC500 MicroComposer, but on the MC909 it's like looking at the piano-roll editor of a software sequencer. Scrolling through a Pattern is simple, and the various cursor and parameter edit tools make moving through note, velocity and length data easy; whatever can be highlighted can have its value changed. Individual events can be copied and pasted, and a comprehensive data filter lets you focus on notes or controller data. The whole window can even be zoomed in or out. And though you edit velocity values in the Microscope data list, you see the effect of edits by the changing heights of 'stalks' in a dedicated part of the window rather like Digidesign's Pro Tools software, in fact! Song Creation The process of chaining Patterns into a Song is one of the least satisfying aspects of the MC909's operation. It's necessary to go into 'record', select the required Pattern, using the display and the value dial, then press the Enter key. You repeat the process until the required Patterns are in the required locations. You can't have the Song playing back at the same time, though you can audition Patterns for each step by pressing the transport's Play key. It's also possible to customise mix and effects settings for each Song step, and edit the chain in a list editor. Though it's efficient, the whole process is rather static and cerebral, with none of the spontaneity would arise from, for example, hitting buttons to chain Patterns in real time. By the way, we tried to cause the 909 to exhibit timing inaccuracies, something that its forebears are said to suffer from, by overloading a Song with busy Patterns full of 32nd notes and controller data, but could hear no problems.
Mixing The software representation of the 909's mixer (see above) is fairly straightforward: 16 channels, each with level fader, pan pot, key shift control (±48 semitones of transposition), reverb send knob and mute switch. Its physical manifestation, immediately below the display (see right), is slightly less comprehensive, though simple button pushes allow its eight real sliders to control every suitable mixer parameter (ie. track level, pan, reverb send level and key shift) for all 16 tracks. The 16 illuminating buttons below the faders work as mute buttons (as well as being part selectors for editing the Patches on each track), and using a mute button in conjunction with the Shift key solos a track. All mixer controls can be automated within a Pattern, though complex mixes require several passes, due to the relatively limited number of dedicated controls. To mix external audio from the inputs alongside 909 audio, press the 'Mix In' button. That audio might be coming from a digital multitracker in the studio or another synth on stage (but the inputs can't accommodate a turntable output without an additional interface). The input can be treated with internal effects, and (most amazingly) can be transposed in real time via the Velocity Pads. Sadly, the latter option can't be recorded as part of a Pattern and the output can't be sampled, but it's a fun trick to have.
Three processors, plus a compressor and mastering processor, are provided. The three main processors comprise a send/return reverb and two multi-effects (MFX1 and MFX2) which work broadly as inserts, though they can be inserted into all 16 mix channels at once if desired. The compressor behaves like the MFX processors, in that you can put all 16 channels through it, but all with the same setting. We would have loved to see an independent compressor for each channel. However, the one you do get is nicely specified and effective, with attack, release, threshold, ratio and gain parameters, plus a simple two-band EQ. There are no user memories or factory presets for effects, and no way to copy settings between Patterns, which is something of a letdown on a machine that is so sophisticated in other ways. These complaints aside, the effects are a good set, as one would expect from Roland. The 24-bit reverb has borrowed a handful of algorithms from the company's stand-alone processors and XV-series synths, and produces smooth, realistic spaces one wouldn't normally expect from a product such as this. There are only four algorithms, but each is fully editable, and again, the display comes into its own here, with graphical feedback as to reverb size, reflection density, and so on (see above).
There doesn't seem to be much front-panel hardware for effects control: just three knobs and five buttons. However, these controls do allow you to quickly mute/unmute and select for editing any of the effects, select an effect type, and then tweak two parameters (usually the most often used ones, such as flanger rate and feedback) for each. Others are accessed via the display. The mastering effect is a fully specified multi-band compressor providing control over crossover frequencies between bands, plus attack, release, threshold, ratio and level. As great as this feature is and it works better than some budget stand-alone compressors we know we still kept wishing we had access to the MC505's killer Low Boost knob! If you like the idea of setting an arpeggio going and then transposing it in real time, the MC909 provides some help. It has a Chord Memory, with which you can generate a whole chord by playing one note; 64 factory chord forms are provided, and you can create 128 of your own. These chords can be arpeggiated, and engaging the Hold button causes the arpeggiated chords to play indefinitely, allowing you to change chords without having to work out how to play them on the pad keyboard. Performance Although it sits perfectly well in the studio as an all-in-one composition machine, the MC909 has been designed just as much for live use. To this end, it has several performance-orientated features.
The D-Beams can also control filter cutoff frequency andresonance, and two turntable-emulation parameters (more on these in a moment). You can set pretty much any parameter in the MC as a destination. The next really obvious control feature of the 909 is the Turntable Emulation section. Here a huge fader like that seen on DJ hardware lets you apply positive and negative changes to playback speed and/or pitch. Changes are also applied to any sample loops in a Pattern, courtesy of real-time time-stretching. The sound quality of stretched audio is generally pretty good, and the real-time aspect is most impressive. A tempo display tells you how much you've changed tempo, and two buttons labelled Hold and Push let you instantly grab the fastest or slowest extreme of the emulation shift. Typically, this feature is for DJs attempting to roughly sync the MC909 to audio from decks during a live mixing session. Tap tempo is also available, but there don't seem to be any BPM-detection features. Turntable emulation is fun for non-DJs, too, but if you don't need the feature and are wishing the slider was a pitch-bend or mod wheel, there's good news, as it can perform either of those functions. Note, though, that it works in the opposite way to most synth wheels: up is down and down up!
As often happens with an instrument of this scope, it's possible to write a long review and still feel you haven't covered all its features, or gone into the ones you have covered in sufficient depth. This is a monster of a Groovebox, it sounds excellent, and it certainly represents the peak of the genre at the moment. Yes, it's a bit on the complex side, but no more than it has to be in order to offer this many integrated facilities. Furthermore, much of the pain that could ordinarily be caused by such a multi-layered beast is removed by the superb display and the logical, software-like user interface it makes possible. The 909 is not perfect Can it compete with the software option, given that a laptop computer and virtual studio software is a very viable way to go, and also given that the MC's £1500 price tag would easily buy that laptop and software, possibly with change? We think it can if you don't want a computer in the studio (those people still exist!), if you gig to any extent (dedicated hardware is probably still safer), or if you just love the immediate feel of a large chunk of high technology on your lap!
