Hi Tom
Many thanks, once again your advice has been invaluable. The only catch was
that percussion bank 128 also needs program change 0 to be set as it does not
default to 0.

Did you send a note off on channel 12? Did you issue
fluid_synth_program_reset()?

No. They only set the channel type, which is basically a no-op to the user. The
type is only considered on a program change event to determine a fallback
instrument bank. That said: I cannot recommend to switch channel types back and
forth with fluid_synth_set_channel_type(). You should rather turn all channels
into melodic ones and select percussion by setting the bank (using e.g.
fluid_synth_bank_select()) appropriately to what it is in your soundfont
(usually bank 128).
Also note that I must correct myself: The bank selection mode only matters when
using fluid_synth_cc(). fluid_synth_bank_select() is not affected by it, you
were correct. Sry for the confusion.
