Roland MC-909


The discontinued Roland MC-909 Sampling Groovebox combines the features of a synthesizer, sequencer, and sampler, with extensive hands-on control of both the sound engine and the sequencing flow. It was intended primarily for live performance of pre-programmed patterns consisting of up to 16 tracks of MIDI data. It was released by Roland Corporation on October 8, 2002. This product was announced at the AES Fall Convention in 2002. It is the direct successor to the Roland MC-505, and is the predecessor to the Roland MC-808.
It was developed from the blueprint of Roland's own "Fantom" workstation and uses the same structure and operating system, with some differences regarding the Patterns section, not implemented in the Fantom.

Sound generation

The MC-909 has a ROM-based sound generator Its patches are built from up to four tones. The tones are based on waves stored in the machine. Patches can also utilize user-created samples. Roland's literature states that the MC-909 has "new-generation XV synthesis", the synth in the MC-909 is a very similar sound engine to that of the XV-5050 64-Voice Synthesizer Module.
The number of PCM waveforms is 693, ranging from vintage synths to strings, drums, guitars and pianos. It can be expanded by adding one SRX card from 12 different cards available.
The MC-909 is always in sequencer mode, as opposed to other workstations that have also a simple Voice or Combination mode for straight playing.
Straight playing via an external keyboard is however possible directly from the sequencer mode by simply selecting one of the 16 tracks where a patch is stored. In this case the MC-909 performs as a regular, 16-part multitimbral sound module, that happens to have a sequencer, too. In essence, the MC-909 can be used as a very capable sound module without ever needing to fire up its sequencer.
The MC-909 is the first Roland groovebox to feature a sampler. It can record audio from any of the external audio inputs, SPDIF connectors, or import wav and aiff files from a computer using a USB port. The sampler can be upgraded up to a total of 272 MB RAM, and the samples can also be stored on a 128 MB 3.3 volt Smartmedia card. The unit is also able to store on two 128 MB Smartmedia cards, if you have larger than 256 MB DATA in its user memory. There are tricks from user forum sites that have found ways to go beyond this limitation using xD-Picture Cards as other means for storage.

Sequencer

The MC-909's sequencer is based on pattern composition. Each pattern has 16 tracks and can have up to 999 measures.
The "pattern" in the groovebox concept as developed by Roland is intended to be a 4-to-16 bars-long small musical phrase made up of 8 to 16 tracks. The chaining of several patterns together will create a full song, or the patterns can be looped as wanted and messed with using the on-board real-time controls.
However, if this was more properly true in the older MC-303 and MC-505, in the MC-909 the massive capacity of the sequencer makes the patterns capable of storing almost 1000 bars, and 16 tracks, thus capable of storing complete songs with arrangements and drum styles.
Each of the 16 parts is set to a specific patch, with its own mixer settings. There are a variety of editing modes: The main modes allow real-time recording, step recording and TR-REC recording. In step recording, notes or chords can be added one at a time. In TR-REC mode, each of the 16 pads represents a point along a musical measure. This speeds up the entry of percussion tracks. Patterns can be strung together into "songs", which, in fact, are mislabelled, merely being chains of patterns played in a specific order. In fact, there is no recording or sequencing capability in Song mode besides pattern chaining and some playback settings.
The sequencer can load Standard MIDI Files and play them back. Additionally, the sequencer will also include samples stored into its memory in the pattern tracks.

Performance

The MC-909 includes a number of features for real time performance. These include:
The follow features are not available on the MC-505 synth:
  1. Sampling ability.
  2. A very large editing LCD screen.
  3. A second D-Beam controller.
  4. Two extra filter modes.
  5. Stereo waveforms for your patches.
  6. Matrix Control, Random Modify and Fat controls.
  7. A mastering stage that features three-band compression and equalization.
  8. Turntable emulation.
  9. Morphing LFO waveforms.
  10. Sample machine gun feature.
  11. Velocity sensitive pads.
  12. Fully editable arpeggios.
  13. Chord memory.
  14. SMF loading
The following features are available on the MC-505 but not on the MC-909:
  1. The MEGAMix function.
  2. The Portamento knob.
  3. The Groove knob. However, the groove/quantize functions are preserved under an editing menu.
  4. The ability to control the individual amount of delay assigned to each part.
  5. The Ad-Lib function from the D-Beam.
Most MC-909 users agree that both machines are different enough to justify keeping both of them and integrate them using a MIDI cable.

Users

The Roland MC-909 was used by the hip hop producer RZA while working on the movies and Kill Bill. RZA uses many Roland products including the Roland Fantom, MV-8000 & Roland MV-8800. Another artist that uses the Roland MC-909 is Switchfoot keyboardist Jerome Fontamillas for live setups.

Criticisms

The Roland MC-909 received good reviews at tech magazines like Future Music and Sound on Sound. However it faced serious competition from the equally powerful Yamaha RS7000. Many MC-909 users complained about several operating system bugs at the Yahoo! Groups forum and also Roland Clan Forums. In fact, even when the machine was released in 2002, it took Roland Corporation 5 years until some of the more complex bugs were fixed in the operating system upgrade v1.23 in early 2007.
Another common complaint refers to the unit's size, which makes it less portable than a laptop with a midi controller.
The unit has been designed with only a 2-prong power inlet, without a ground lift; hence, there have been complaints of light electrical discharges from its metallic body when handled with less-than-dry hands.
Further criticism pointed out the uneven volume ranges of its voices, waveforms and sounds.
Additionally, critics noted that, for a machine aimed at the dance/techno/electronica market, the sound engine was excessively rich in sounds from ethnic, classical and band instruments.
The sampler, although powerful, has a very complex access-and-editing route and lacks the ability to set keyboard ranges for different samples, making it difficult to create realistic sounds from a set of multisamples. There is, however, a work-around for this via an external editor on the PC & Mac called: MC-909 Editor Update v3.1, that is freely available for download at
The inputs, used for either sampling or sound processing of an external sound source, are routed through the effects engine and heard at the outputs during real-time. However, re-sampling is necessary in order for the sample to contain the effects as a part of the sample. Following any re-sampling, the sample playback can be further re-sampled or processed by more effects at the outputs during playback.
The Roland MC-909 is no longer in production by Roland Corporation. The Roland MC-909 is consequently called to become a cult item, as Mellotron or the TB-303.
While no longer in production, the MC-909 can be bought these days second-hand at places like eBay, with a typical second-hand purchase price, as of 2013, around US$600. The original MSRP price set by Roland in 2002 was US$1,795.99.

Unsolved bugs

Several operating system bugs were gradually solved over time; the last operating system upgrade was introduced on March 30, 2007.
The current unsolved problems at the present moment are:
There are current unresolved issues with the implementation of effects when switching patterns, but the MC-909 was "designed by specification". Roland might refer to the end users' requests for effects that sustain past the point when the pattern switches as they "developing a future new product".
The last operating system upgrade, corrected few issue with:
