8. Tempo: Tap this button at the desired rate to enter a new tempo.
Important: This feature does not work when the VI49 is set to External sync.
9. Roll: Press this button to activate or deactivate Roll Mode. In this mode, pressing and
holding a pad (that is set to send Note On messages) causes the pad to retrigger at a rate
based on the current Tempo and Time Division settings. This button can function as a
toggle (latching) or momentary button.
In Roll Mode, some controls have different functions:
•
Press one of Assignable Buttons 25–32 to select the current Time Division, which
determines the rate of the Roll feature.
•
Turn Assignable Knob 1 to adjust the Gate, which determines the length of the
repeated note.
•
Turn Assignable Knob 2 to adjust the Swing, which determines how much swing (a
"shuffle" feel) is applied to the repeated note.
10. Transport Buttons: These six buttons are dedicated buttons for sending conventional
transport control commands: Rewind, Fast-Forward, Stop, Play, Loop, and Record.
You can also use the VI Editor software to set each button to send MIDI CC messages to
your software or external MIDI device. See the VI Editor's User Guide to learn how to do
this.
11. Display: Use this LCD screen to view parameter values relevant to VI49's current
operation.
12. Preset Down/Up (): Use these arrow buttons to change the current preset of VI49.

1. Power Input: If you do not want to use a
computer in your setup (i.e., if you are
using VI49 to control an external MIDI
module), connect VI49's power input to a
power outlet using an optional power
adapter (9 V DC, 500 mA, center-positive,
sold separately). Alternatively, you can
connect VI49's USB Port to a power
outlet using a standard USB charger (sold
separately).
2. Power Switch: Press this button to power the VI49 on or off.
3. USB Port: Use a standard USB cable to connect this USB port to your computer. The
computer's USB port provides ample power to VI49. This connection is also used to send
and receive MIDI data to and from your computer.
If an external device is connected to the MIDI Out, your computer can send MIDI
messages via USB to the VI49, which will then send the message to the external device.
4. MIDI Out: Use a standard five-pin MIDI cable to connect this MIDI Out to the MIDI In of
an external MIDI device (e.g., a synthesizer, sequencer, drum machine, etc.).
5. Sustain Input: Connect an optional 1/4" TS sustain pedal to this input.
You can also use the VI Editor software to set the sustain pedal to send other MIDI CC
messages to your software or external MIDI device. See the VI Editor's User Guide to
learn how to do this.
