Function Documentation

defaultDrumkitFunc()

int8_t defaultDrumkitFunc	(	percussionNote_t	drum,
		uint32_t	idx,
		bool *	done,
		uint32_t	scratch[4],
		void *	data )

Produces sounds for a standard drumkit according to the General MIDI standard.

Parameters

drum	The MIDI note corresponding to the drum to play
idx	The sample index, which should start at 0 for each note and increase by one every sample
done	A pointer to a boolean which will be set to true when the drum is finished sounding
scratch	Not used by this drumkit
data	Not used by this drumkit

Returns

int8_t The signed 8-bit sample generated for this tick of the drumkit

donutDrumkitFunc()

int8_t donutDrumkitFunc	(	percussionNote_t	drum,
		uint32_t	idx,
		bool *	done,
		uint32_t	scratch[4],
		void *	data )

Produces sounds for the drumkit that was included on the King Donut synth swadge.

This drumkit does not use the General MIDI drum note numbers

Parameters

drum	The drum index, between ACOUSTIC_BASS_DRUM_OR_LOW_BASS_DRUM and HIGH_BONGO, inclusive
idx	The sample index
done	A pointer to a boolean which will be set to true when the drum is finished sounding
scratch	Scratch space which is used to faithfully reproduce the drum sounds
data	Not used by this drumkit

Returns

int8_t The signed 8-bit sample generated for this tick of the drumkit

mmxDrumkitFunc()

int8_t mmxDrumkitFunc	(	percussionNote_t	drum,
		uint32_t	idx,
		bool *	done,
		uint32_t	scratch[4],
		void *	data )
