The total amount of RAM memory available to a project is 85,5 MB. This memory is shared by Flex RAM,
which is used when loading Flex samples, and track recorder memory, which is used when sampling. In
this menu the distribution of Flex RAM and track recorder memory can be set. To the right a bar is shown
visualizing the memory distribution. The dotted area in the top represents occupied Flex memory, the
black area in the middle represents free RAM and the white area in the bottom represents reserved track
recorder memory.
Changes made does not come into eect until exiting the menu. When doing so, a prompt will appear
asking you to confirm the changes. This is because the recorder buers are cleared when changes are
made and confirmed.
FLEX FORMAT controls what bit depth samples will be in when loaded to the Flex sample slot list.
Samples loaded to the Static slot list are unaected by this setting. Two settings exist.
• 24-BIT will retain the bit depth of 24-bit samples when they are loaded. 16-bit samples will still be
in 16-bit.
• 16-BIT will convert 24-bit samples to 16-bit samples when loaded, meaning samples will occupy
less Flex RAM memory at the cost of reduced bit depth. If a sample is saved when this setting is
active, it will be saved as a 16 bit sample no matter the original bit depth. If a 24-bit sample is saved
a prompt will appear informing it will be saved as a 16-bit sample.
DYNAMIC RECORDERS oers two settings.
• NO forces the track recorders to use only the track recorder memory, which by default is 16 sec-
onds of sampling time per track recorder. It is possible to increase or decrease the available track
recorder memory by using the RESERVE RECORDINGS and the RESERVE LENGTH settings.
• YES makes it possible for track recorders to exceed the track recorder memory and utilize any
free Flex RAM memory.
RECORDER FORMAT selects in what bit depth the track recorders will sample. 24-bit and 16-bit
settings are available.
RESERVE RECORDINGS chooses which track recorders that can be assigned a certain amount of
dedicated sample time. This setting in combination with the RESERVE LENGTH setting basically
decides the size of the track recorder memory.
• R1...R1-R8 selects the track recorders that will be aected by the RESERVE LENGTH setting.
Track recorders outside the selected track recorder range will not have any track recorder memory
allocated, making it impossible for them to sample unless DYNAMIC RECORDERS is set to YES.
These track recorders will then use the Flex RAM memory when sampling.
• NONE will add all track recorder memory to the Flex RAM memory, making the total amount of
available RAM, which is 85.5 MB, consist of only Flex RAM. As no track recorder memory will be
available to the track recorders, sampling will be not be possible unless DYNAMIC RECORDERS
is set to YES. The track recorders will then utilize the available Flex RAM memory when sampling.
When NONE is selected the RESERVE LENGTH setting will have no eect at all.
RESERVE LENGTH makes it possible to reserve sample time to the track recorders chosen by the
RESERVE RECORDINGS setting. These track recorders will always be able to sample the amount of
seconds set here. When selecting the reserved sample time, the equivalent in sequencer steps based
on the current BPM, as well as the amount of RAM the reserved time will occupy, is shown in the
upper left corner of the screen. The white bar in the lower right corner of the screen will also change
according to size of the reserved track recorder memory . The more track recorders aected and the
more sampling time reserved, the less Flex RAM will become available for Flex samples. This works
the other way around as well. Less reserved sampling time means more Flex RAM will be available. If
DYNAMIC RECORDERS is set to YES and the reserved sampling time is exceeded when sampling,
the track recorders will start using the available Flex RAM memory.
By reserving a large amount of RAM memory to a track recorder, internal sampling of com-
plete Octatrack MKII songs are possible.
