Hi Ben,
On Windows, using your soundfont (gonzos-20160702.sf2), in mono mode i
haven't expererienced absolutely no cpu excess usage, on alls 6 presets.
I have look inside the preset. Each preset make use of 2 simulateneous
voices maximum. So this is a very low CPU usage soundfont.
Normally on a RPi2 you can run 180 voices (using the 4 cores of course).
Even if fluidsynth use only one core, the maximum number of voices
falls to 45 which is sufficient to play any preset on this soundfont. So
really, i don't understand what happens on your setting.
Anyway, i have got a RPi2. So I will try this and also an other machine
with Debian. I will return the results, using the same soundfont.

Yes , i confirm this is currently a know limitation and it occurs only
on legato mode 1,2,3 but not on legato mode 0.
Playing a legato passage, n1,n2,n3,... using legato mode 1,2,3:
The notes (n2,n3,..) following the first (n1) make use of running voices
of n1, (regardless of the keyRange and Velocity Range), so the notes
n2,n3,... make use
of the IZ (Instruments Zone) of note n1 ignoring possible others IZ with
their samples. In others words, the actual patch doesn't not follows
fully the instructions
given by the soundfont designer. This is a serious limitation. But
anyway, i 'm working to cancel this limitation.

Hi
I downloaded the git snapshot, used the patch from Mr(?) Horn
(thankyou), and re-complied.
I'm still experiencing the CPU runaway. It happens a) if I put the
channel I'm using into MONO or b) if I use cc ch 68 127 (legato on).
It doesn't matter which setlegatomode I am using for the channel. Note
that it happens on 5 out of 6 of the voices I am using. I can't see
any significant config differences between the voices when using
Swami. One voice works fine.
The legato is working, and I have noticed that if I do a long
descending glissando to the lower register on the clarinet, the voice
that I end up with on the low note is the voice I started with - I
don't get the low reedy sound until I stop and play the note again.
Jean-Jacques said this was a limitation.
For info, I'm running a RPi2 with Raspbian Jessie, all latest updates
installed. I'm trying to get legato working on channels 10-15
inclusive, and I'm not using the other channels.

This prompted me for each file to patch, and I typed in the path to

I don't know how Jean-Jacques generated his patch, but the diff
should be against a complete source tree so this isn't necessary.
I've combined everything, including the new files, into a single
patch (against a git snapshot from a couple of hours ago...the
original patch fails against the 1.1.6 distribution) which should be
attached.
Just execute patch -p1 < fluidsynth-polymono.patch (or zcat
fluidsynth-polymono.patch.gz | patch -p1) from the top of the source
tree and you should be ready to run cmake and build.
