Roland MC-909 - Unsolved Bugs

Unsolved Bugs

Several operating system bugs were gradually solved over time; the last operating system upgrade (Version 1.23) was introduced on March 30, 2007.

The current unsolved problems at the present moment are:

  • Many users complain that there is no sustain in Song Mode, resulting in a noticeable audio gapping between patterns. This is most noticeable as slower tempos. (Although different Machine, see also: MC-808 Roland MC-808#Unresolved issues)
  • Even when a part is set to EXT, the internal sound engine will continue to produce sounds. You can work this around by assigning a blank patch to that part; however this is not the expected behaviour described in the manual.
  • Going into MENU (e.g. USB transfer) resets the 909 to Preset Pattern 1 when you come out of menu.
  • Tracks 6 and 13 will not mute/unmute when pressed at the same time (introduced in v1.22)

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 (Version 1.23), corrected few issue with:

  • RPS Setting, RPS Mixer WRITE editor of the contents of operation does not save a fixed point.
  • Import BMP features and functionality Realtime Erase fixed.
  • Song editing function has been strengthened.
  • Sounds & Effects strengthened, Stable for tuning various countries. (Roland Corp. Japan Trans: MC-909 VER. History List )

Famous quotes containing the words unsolved and/or bugs:

    “The child knows only that he engages in play because it is enjoyable. He isn’t aware of his need to play—a need which has its source in the pressure of unsolved problems. Nor does he know that his pleasure in playing comes from a deep sense of well-being that is the direct result of feeling in control of things, in contrast to the rest of his life, which is managed by his parents or other adults.”
    —Bruno Bettelheim (20th century)

    “It is snowing and death bugs me
    as stubborn as insomnia.
    The fierce bubbles of chalk,
    the little white lesions
    settle on the street outside.”
    —Anne Sexton (1928–1974)
