Re: I am thinking of buying a karma and am concerned about running out of seq me

Here is a quote from the FAQs relating to this issue:

"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]

Here you can see which MIDI Channels are assigned to which tracks.
(2) (6.1-2) [Menu]->[KARM]->[MIDI I/O] Here you can see which 
timbres (on which channels) are actually being sent data from KARMA.
+ Parameter Guide, Pages 82, 104. Let's take a simple example. Combi 
A016: Earthy Groove. As you can see by looking in both places, only 
tracks 1, 2 and 3 (receiving on channels 2, 3 & 4) need to be 
enabled to record, because they are the only tracks doing anything.
Another (more complex) example: Combi A000:==Voice Of KARMA==
Using Method (2) above, we see that KARMA Modules are generating on
timbres 4,5,6,7 & 8. Using Method (1) above we also see that tracks 
1, 2 & 3 are on Channel 1, to be played live. However, here's 
another interesting thing: in this case, tracks 1,2 & 3 are all set 
to MIDI Channel 1 (this is the LH Pad sound and the RH Lead Sound, 
configured with key zones into a split). Even with multi track 
record on and all tracks enabled, when you play on the keyboard the
system only records 1 track of data (on to track 1), because the 
other tracks are set to the same channel. Tracks 2 & 3 will record 
nothing. However, because they are record enabled, they probably 
still eat up potential available memory. The same thing goes with 
tracks 7 and 8 (the KARMA drum groove), which are both receiving on 
MIDI Channel 5. Even if both of these are enabled, data only gets 
recorded on the first one. So in this case, to record just the KARMA 
output (and have the most memory available), enable 4,5,6 and 7. To 
record the live keyboard parts along with it, just additionally 
enable track 1.

If all this sounds complicated, just remember that you don't have to 
do this unless you are having problems running out of memory while
recording. Many of you may never run into this problem."

Hope that helps.
Cheers,
Eric
