of 127. The range between the two values is the dynamic range.
The sustain is the level as played by the R-8.
Now follows, as already mentioned, the Decay envelope, which
acts completely independently of the previous envelope. The
Decay
parameter is the decay time of the sample, which you still
have access to later in your R-8. The
Min Dec
parameter, on the
other hand, sets the minimum decay time of the sample to limit
the user input to the device. If you set this parameter to 4, for
example, the user can drag the value to zero using the slider on
the R-8, but the decay time will always be at least 4.
I'm sure you've noticed this before on your R-8, but we'd better
tell you again here. A decay of 0 is not equal to 0. The R-8 will
always play at least 16ms of your sample, even if you drag the
slider to 0. So if you want to be able to completely fade out your
sample via the Decay parameter, you have to insert about 16ms
of silence at the beginning of your sample, but then the attack
also goes into the void.
Now we come to the
Level
control and the di
ff
erence to Sustain.
Level is the volume at which the sample is placed on the card.
Sustain, on the other hand, is the volume at which the R-8 plays
the sample. You wonder what this is for? Well, the level a
ff
ects
the entire sample, the sustain is just part of the envelope. Also,
because of the R-8's internal processing, it can distort your
sample. Here you should turn the level down slightly.
Who noticed the funny values from 0 to 127 that don't even have
a unit?
What does that mean? That's easy to answer:
The unit is
Roland’s
, their design and implementation has a val-
ue range from 0 to 127 and are so non-linear that we had a hard
time providing the user with a function that reveals what they
are doing.
The values are logarithmic and correspond to dB values, but not
integer ones, so they are not as memorable. We have therefore
decided to choose the unit name as Roland.
If you want to know exactly and do all the math, calculate
20*
log10 (x * 1 / 127)
. The others may please take the following
facts as given:
A halving of the value corresponds to a decrease of 6dB, a dou-
bling of the value corresponds to an increase of 6dB. In the fol-
lowing, briefly exemplary a few values and their correspondence
in dB.
