Older synthesizers had arpeggiators,
and now new synths can have them too with Sweet MIDI Arpeggiator. This
'virtual arpeggiator' program contains four arpeggio objects that will
arpeggiate all MIDI notes that pass through it.
With this program, you can change the arpeggio direction, number of
octaves, and length of the arpeggiated notes. You can also modify the
rhythm values of the arpeggiated notes and add another arpeggio object
by choosing the same MIDI channel for the object.
The arpeggiators can run from the program's internal tempo engine or
synchronize to other software that sends MIDI Clock messages. Settings
can be saved for later loading. Sweet MIDI Arpeggiator features a clean-looking
interface that shouldn't take too long to figure out.
Sweet MIDI Arpeggiator will work with all Windows programs that
use standard Windows MIDI drivers.
