Edit Section [Voice4] Envelope This page lets you adjust the volume envelope of the voice assigned to the note number. Every musical instrument has a unique volume envelope that helps distinguish what kind of instrument it is. For drum or percussion instruments, their unique characteristics come from the attack and decay rates (speeds) in the volume envelope. Adjusting these two factors lets you create a variety of tonal nuances in the voice. [Voice4] Attack Decay 49C#2 0 0 1 2 3 Level Peak [Voice5] Polyphony This page lets you set how many polyphonic voices are allowed for the specified note number. The built-in tone generator can play up to 64 polyphonic notes at a time. However, there may be times when this may not be enough - particularly if you play along with many parts in a song or play the drum kit with a large number of short notes. You can prevent this by limiting the polyphony for each drum voice.

Attack Decay Time 1 Note Number & Name Determines a target note number (13~94: C#-1~A#5). Each note number is shown with a specific note name. 2 Attack Determines the attack rate of the current voice. The larger the positive value, the faster the attack rate. The larger the negative value, the slower the attack rate. Keep in mind that if the voice originally has a fast attack rate, specifying higher values cannot make the rate faster past a certain point. ❏ Settings: -64~+63 (slower to faster) 3 Decay Determines the decay rate of the current voice. The larger the negative value, the slower the decay rate. The larger the positive value, the faster the decay rate. If you want a cymbal with a long release, set its decay rate to a large negative value. A large positive value may cause the sound to cut off unnaturally. ❏ Settings: -64~+63 (slower to faster) 2 KeyMode Determines how the same voice is played in response to multiple notes. ❏ Settings: • poly: No limitation until the DTXTREME IIs tone generator reaches maximum polyphony. • semi8: Up to eight polyphonic notes - every initial note will be muted to play the 9th note. • semi4: Up to four polyphonic notes - every initial note will be muted to play the 5th note. • semi3: Up to three polyphonic notes - every initial note will be muted to play the 4th note. • semi2: Up to two polyphonic notes - every initial note will be muted to play the 3rd note. • mono: Only a single note - each note will be muted by the subsequently played note. • himono: Same as mono, but excluded from the last-note priority rule - notes are never muted by other notes. n If a note number (drum pad) is set to mono and assigned with a voice with a long release (such as cymbal), hitting that pad continuously will cut off the previous sound unnaturally. However, setting every note number to poly to prevent this situation is not a good idea, since this may "steal" polyphony from other important parts. 51
