* Synthesize a block of floating point audio to separate audio buffers (multichannel rendering). First effect channel used by reverb, second for chorus.
* @param synth FluidSynth instance
* @param len Count of audio frames to synthesize
* @param left Array of arrays of floats to store left channel of planar audio (\c len in size)
* @param right Array of arrays of floats to store right channel of planar audio (\c len in size)
* @param fx_left Since 1.1.7: If not \c NULL, array of arrays of floats to store left effect channel (reverb and chrous, \c len in size)
* @param fx_right Since 1.1.7: If not \c NULL, array of arrays of floats to store right effect channel (reverb and chorus, \c len in size)
* @param left Array of float buffers to store left channel of planar audio (as many as \c synth.audio-channels buffers, each of \c len in size)
* @param right Array of float buffers to store right channel of planar audio (size: dito)
* @param fx_left Since 1.1.7: If not \c NULL, array of arrays of floats to store left effect channel (as many as \c synth.effects-channels buffers, each of \c len in size)
* @param fx_right Since 1.1.7: If not \c NULL, array of arrays of floats to store right effect channel (size: dito)
* @return FLUID_OK on success, FLUID_FAIL otherwise

* @note Should only be called from synthesis thread.
