[rodgersorganusers] New member message, plus PR-300S question

Hi Folks,

I have been following the group for about a month, but have not yet posted. 
To introduce myself, I am a volunteer "Organ Curator" of the David Ulrich 
Memorial Organ at Saint Ignatius Loyola Cathedral (RC) in Palm Beach 
Gardens, Florida. This involves understanding the organ from a technical 
standpoint, and making sure everything is A-OK. I will also be substituting 
for our organist, but have not done so yet.

We have a Rodgers custom four manual organ with a PR-300S unit. This is a 
really max'ed out organ with lots of custom samples. Many of the samples 
are of the wonderful Ruffatti organ in Coral Ridge Presbyterian Church in 
Fort Lauderdale, Florida. It is truly a magnificent example of Rodgers art. 
Our Director of the Office of Worship, Art, and Environment, who is also 
the organist, Arthur Nobile, Jr., is equally remarkable. I expect to 
substitute for him after Christmas, but could never fill his shoes, nor 
match his incredible keyboard magic!

I have a question regarding the PR-300S. When Arthur attempts to record 
certain extremely dense virtuoso pieces, we get a MIDI Buffer Full message 
on the PR, and it stops recording. The last time this happened, we had 
already recorded three separate selections in the internal memory, using 
the first three tracks. Those selections were moderate in length, and not 
terribly complex. We lost those selections, and I am not certain whether it 
was because of the buffer full event that happened while attempting to 
record a very complex piece on the fourth track, or whether it was 
something that I did while trying to save the first three tracks to disk 
after the buffer full event. Honestly, I did not notice if tracks 1 through 
3 were still okay before I attempted to save them. I got a "no song" 
message, and realized they were gone. Has anyone experienced anything like 
this with their PR-300S?

Another question: is there a separate high-speed shift register type buffer 
that receives incoming MIDI messages rapidly and then moves them to the 
main memory when it can, or is the "buffer" that the message refers to the 
main memory itself? I understand that there is an approximate 40k message 
limit on the memory, but I am trying to figure out if we simply exceeded 
that limit, or if extended passages of extremely rapid notes could cause 
the problem even if the memory still has room for the messages (i.e., is it 
a TIME related or total SPACE related problem).

Thanks for any insights you can give. Regardless though, I have really been 
enjoying this group!

Jack Cloninger
