With Release Type set to Stop Wait, if there is already something playing to sync to, the
current riff will wait for what is playing to stop before releasing. This way you can trigger
the riff to stop ahead of time, and have it stop in sync at the release (stopping) of the riff,
arpeggiator, or song that you are syncing to. The difference from Stop is that if there is
nothing playing to sync to, the riff will not stop when released. If the riff, arpeggiator, or
song that you are syncing to is already running, Stop Wait behaves just like Stop.
Note: For all Release Type settings except Stop, Start Wait and Stop Wait, a riff can sync its
release with its self. For example, you could use riff 1 and sync it to its self by setting Riff
Zone 1 for the Release Master parameter. Then, if you set Down Beat for the Release Type
parameter, when released the riff would always wait until its next down beat to stop.
Duration
Duration changes the duration of each MIDI note. The original durations of the notes in
the sequence are multiplied by the selected percentage. 100% will cause no change, values
smaller than 100% will result in shorter durations, values larger than 100% will result in
longer durations.
Velocity
Velocity changes the velocity of each MIDI note. The original velocities of the notes in
the sequence are multiplied by the selected percentage. 100% will cause no change, values
smaller than 100% will result in lower velocities, values larger than 100% will result in
higher velocities.
Offset
You can fine tune the start time of your riff in ticks by using the Offset parameter. A positive
value will delay the start time, while a negative value will speed up the start time.
