This is identical in function to the LADSPA run() - * function, except that it also supplies events to the synth. - * - * A plugin may provide this function, run_multiple_synths() (see - * below), both, or neither (if it is not in fact a synth). A - * plugin that does not provide this function must set this member - * to NULL. Authors of synth plugins are encouraged to provide - * this function if at all possible. - * - * The Events pointer points to a block of EventCount ALSA - * sequencer events, which is used to communicate MIDI and related - * events to the synth. Each event is timestamped relative to the - * start of the block, (mis)using the ALSA "tick time" field as a - * frame count. The host is responsible for ensuring that events - * with differing timestamps are already ordered by time. - * - * See also the notes on activation, port connection etc in - * ladpsa.h, in the context of the LADSPA run() function. - * - * Note Events - * ~~~~~~~~~~~ - * There are two minor requirements aimed at making the plugin - * writer's life as simple as possible: - * - * 1. A host must never send events of type SND_SEQ_EVENT_NOTE. - * Notes should always be sent as separate SND_SEQ_EVENT_NOTE_ON - * and NOTE_OFF events. A plugin should discard any one-point - * NOTE events it sees. - * - * 2. A host must not attempt to switch notes off by sending - * zero-velocity NOTE_ON events. It should always send true ///interesting ..this is probably what was going on with all of those NOTE_ONs, some of them were probably zero velocity - * NOTE_OFFs. It is the host's responsibility to remap events in - * cases where an external MIDI source has sent it zero-velocity - * NOTE_ONs. - * - * Bank and Program Events - * ~~~~~~~~~~~~~~~~~~~~~~~ - * Hosts must map MIDI Bank Select MSB and LSB (0 and 32) - * controllers and MIDI Program Change events onto the banks and - * programs specified by the plugin, using the DSSI select_program - * call.
