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

> Do the channel_type commands above also set the bank?

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.
