Section 6: Sequence Mode, Sequencing, RPPR, Patterns (48)

1. I get "Sequencer Out Of Memory" messages when recording with
the KARMA Function.
The sequencer has a capacity of 200,000 events. When you enable
multi-track record, the available memory is divided by the number of
enabled tracks, and then by 2 (to allow for the compare function). In
other words, a memory buffer is provided for each enabled track. If any
track exceeds this buffer while recording, you get the out-of-memory
situation.
Here's an example: Assuming starting with an empty sequencer, if 16
tracks are enabled, you have (200,000/16)/2, or 6,250 events per track.
Some KARMA GEs generate large amounts of MIDI data, when there are
3 or 4 different CCs being generated, in addition to notes, pitch bend
info, etc. 6,250 events is not all that much, especially where KARMA is
concerned. In some combis, you could run out of memory after 48 bars
or so.
But this is because ALL 16 TRACKS ARE RECORD ENABLED.
If you copy a Combi into the sequencer, at the most you will be recording
the output of 4 KARMA GEs, and maybe the keyboard sound. If you only
enable the tracks that are actually being used, you greatly increase the
amount of available memory for recording.
A quick fix is to disable tracks 9-16 (assuming you copied a Combi to
tracks 1-8, or the other way around if you copied to 9-16). In this case,
you've doubled the amount of available memory to 12,500 events per
track. But let's say you then go look at the channel routing assignments,
and determine that you can turn off 4 other tracks that are not actually
being used - you've now quadrupled the available memory 25,000 events
per track!
Note that if you are familiar with the Triton, this is not any different than
the Triton sequencer. One difference is that KARMA generates large
amounts of MIDI data, so your events can get eaten up more quickly
than using the Triton's arpeggiators, for example.
There are 2 places to check for MIDI routing:
(1) (3.1-1/2) [Menu]->[PRM1]->[MIDI...8] or [MIDI..16]
