chan 10, Music Box
chan 11, Vibraphone
chan 12, Marimba
chan 13, Xylophone

I try change instrument in sequencer (or in virtual keyboard), but fluidsynth play own
instrument (for example, i select bass-guitar on channel 12, but fluidsynth play Marimba).
Is it right ? May be i must to load font with options, which instrument load to channel ?
I cann't find "docs and tutorial" about fluidsynth.
Please help me.
Sorry for a possible mistakes, WBR
Roman.

no instr on channel 9! i try prog 9 128-000, prog 9 024-128 and other combinations - no result.
also, when i try to load instrument with bank!=0, f.e. "001-081 VanHalen 'Jump' Saw", fluidsynth load
an instrument with same number and bank number == 0.

and can i to change instrument number in sequencer, or i MUST do it in fluidsynth? it's ok with midi-keyboard,
but strangely with sequencer.

may be i can see docs, manuals and/or tutorial about fluidsynth? i cann't find on fluidsynth.org and in fluidsynth-tarball. it's a good program, and i want to use it completely.

sorry for possible mistakes, WBR

To select other banks than bank 0, use :
select <chan> <sfont> <bank> <preset>
example :
select 12 0 128 16
=> selects preset 16 of bank 128 of sfont 0 on channel 12
(sfont 0 is the first loaded soundfont file, sfont 1 the second, etc..)

For the documentation of the fluidsynth.exe commands, please use the
'help' command (and 'help help' is useful).

For the documentation of the fluidsynth library, please refer to the
CVS sources. There is a documentation file.

Hope this helps,

I fixed a nasty bug that dropped random noteon events:
In defsfont.C, the instrument zone's lokey was not initialized. So if
a loaded soundfont did not have a lokey defined for an instrument
zone, the lokey in RAM was set to whatever value was in memory at
that moment. Thus all noteon below that random number were dropped on
that channel/preset/instrument. It was nasty to find because it does
not happen in the debugger (in VC++)...

Fixed in CVS.

It seems that the refcount/notify scheme defined in the sample_t API
is never used nor implemented in the fluidsynth code.
Am I missing something ?

Sorry for the very short message above. What I meant is : I dont seem
to be able to figure out, given the current implementation, if I can
delete a sample or not, as it might be currently used in a voice. Am
I right?
