David, and all:
As requested in the e-mail below, I re-ran my tests on an Ubuntu 12.04
partition, on a 2.5 gigahertz machine.
Per your instructions, I re-built, and re-installed the
release-candidate fluidsynth, and verified that the newly-generated
software was actually being used.
I re-ran the tests, with results as follows:
Ran test 1 (Impromptu 2 - Sunlight on the Water):
Played perfectly - no underruns. Qjackctl RT-percentage hovering around
18%.
Ran test 2 (Impromptu - Forest Breezes):
Checked the "Chorus" checkbox, to introduce more overhead.
Played perfectly - no underruns. Qjackctl RT-percentage hovering around
19%.
TEST CONCLUSIONS:
The tests ran successfully on an Ubuntu 12.04 (i386) 2.5 gigahertz
unit-processor. As I recall from the prior testing, there was
significantly less real-time load (as displayed by qjackctl).
Given the problems I had getting qjackctl to co-exist with the generated
version of fluidsynth, I am puzzled by why I had no problems with my
Ubuntu partition. My guesses why are as follows:
1. I had previously done some testing of a Rosegarden fix, and it has
similar dependencies to fluidsynth. Notably, it wants jackd1 (rather
than jackd2, which qjackctl causes to be installed). All this was
in-place and working before I attempted to build fluidsynth.
2. I am using Ubuntu, rather than Xubuntu.
I have attached a text file with my build listings, which you can
compare with the similar listings attached to my prior e-mail, allowing
you to investigate fluidsynth jack dependencies (or lack thereof).
Sincerely,
Aere
