For my first (and probably last) drum machine, I wanted the most powerful
machine available. With the possible exception of some of the sampling
production stations, the R-8 MK II must be it. As far as I can tell, it is
pretty identical to the original R-8, except for a far larger
set of onboard sounds.The feature set is largely what one would expect. The unit has a stereo
output and eight polyphonic outs. There's a song mode where
patterns can be chained and looped, tempos programmed, and markers set.
Patterns can be programmed in real time or in a matrix-based step mode.
Versatile editing modes allow event timing to be altered with accuracy,
and the individual pitch, decay, nuance, pan and velocity of sounds
in a pattern can be swept and altered in real time while a pattern plays.
The programming interface is typical Roland, but there is a logic to it;
one just has to discover it for oneself.The most innovative feature of the machine is the provision of
feel patches,
which are templates for altering attributes of specific sounds
within a pattern, either according to a rhythm template, or via
various kinds of random variation. Programming of feel patches is fiddly,
but the results are worthwhile.The MIDI specification of the instrument is quite sophisticated. MIDI
controllers can be routed to various sound parameters, and of course
MIDI note data can be generated or received. Controller data is also
generated to reflect parameter variations within patterns. The system
exclusive format follows the memory map model found on recent Roland
synthesisers, and seems to work well.The major drawback of the instrument, from my point of view, is the
monolithic and intertwined nature of the various data objects, making
it very hard to organise and manage sounds and patterns. Sounds have
their own global settings (pan, output assign and so on), stored
according to the original sample. Patterns
refer to these sounds by sample number
and contain their own settings. Feel patches refer to
sounds globally, and there are only ten feel patches to be shared amongst
all possible patterns. Pad sounds and parameters are global and unrelated
to patterns or songs. It is impossible to perform a uniform edit to a set of
closely related patterns.To be fair, I suspect that most drum machines are organised this way;
the notion of "patch", "preset" or "performance" as found on synthesisers
has not made it as far as the average drum box. These problems are solvable
with external software such as Max,
although some work would be required.The only other drawback of the machine is its size, although this is also
a benefit when programming. The LCD screen is rather small and not
backlit, which is a shame. Otherwise, this is a fine machine, although
it does require a particular mindset.The R-8 MK II takes the same PCM sample cards as the R-8, although it
has such a large selection of onboard sounds that it's probably not
worth hunting cards down, especially given the high prices charged for
them.
