256 /* * attackv(midisyn *ms, * uint_fast16_t voice, midipitch_t mp, int16_t level_cB); * Attack the voice 'voice' at pitch 'midipitch' with level 'level_cB'. * The pitch is in MIDI Tuning units and accounts for all of the pitch * adjustment controls that midisyn supports and that the driver has * not reported handling internally. The level is in centibels of * attenuation (0 == no attenuation, full output; reduced levels are * negative) and again accounts for all level adjustments midisyn * supports, except any the driver reports handling itself. * The program used for the voice should be the current program of the * voice's associated MIDI channel, and can be queried with MS_GETPGM. */
