PRODUCT OVERVIEW
Top Panel
1. Parameter Control Buttons: These buttons can be assigned to send Control Change
messages and can be used to send continuous control data to a digital audio
workstation (DAW).
2. Memory Button: The SRP64 features 6 built-in memory slots for storing button
assignments and settings. Press and hold the Memory button and press one of the 6

7
Pads to the right of the Memory button to recall the settings assigned to that Pad.
Momentarily press the Memory button, then press one of the 6 Pads to the right of
the Memory button, to save the current button assignments and settings to the
memory slot assigned to that Pad.
3. Trigger Pads: The 8x8 grid of velocity and pressure sensitive Pads can be configured
to send Note or Control Change messages. They can be used to trigger drum hits to
your software or hardware module.
4. Note Button: Press the Note button to configure the Pads to send Note messages.
Use the ▲and ▼buttons to increase or decrease the current Note by a semitone.
5. Octave Button: Press the Octave button, then use the ▲and ▼buttons to increase
or decrease the Octave setting. The range of settings is 0-4 with 0 being the initial
setting. Press both the ▲and ▼buttons at the same time to reset the Octave
setting to 0.
6. A-touch Button: Press the A-touch button to control the Aftertouch function. Press
the button once to enter Channel Aftertouch Mode, press it a second time to enter
Keyboard Aftertouch Mode, and finally press it a third time to disable Aftertouch
Mode. The button illuminates red when in Channel Aftertouch Mode and the SRP64
will send Channel Aftertouch information when pressing the Pads. The button
illuminates blue when in Keyboard Aftertouch Mode and the SRP64 will send
Keyboard Aftertouch information when pressing the Pads.
7. Channel Button: Press the Channel button, then use the ▲and ▼buttons to
increase or decrease the Channel setting. The range of settings is 1-16 with 1 being
the initial setting.
8. Velocity Button: Press the Velocity button to cycle through the different velocity
settings. The button illuminates green when Normal velocity is selected, red when
Heavy velocity is selected, and blue when Constant velocity is selected.
9. Mute Button: Press the Mute button to toggle controller mute on or off. When
Mute is on, the SRP64 cannot send any MIDI messages.

11. MMC Buttons: These six buttons default to send MIDI Machine Control messages to
a sequencer. From top to bottom, the buttons perform Play, Fast Forward, Rewind,
Record, Stop, and Loop functions. Press the ◄◄ and ►buttons at the same time
to set the buttons to send Control Change messages instead of MMC messages.
12. ▲and ▼Buttons: These buttons are used to increase or decrease values and to

CONTROL SOFTWARE
This Grid Controller includes Control Software to change and manage the various settings.
Download the Windows® or Mac® software package from the 625895 page on the
monoprice.com website, connect the SRP64 to your computer, then run the software to
control the settings. While the software is intuitive and easy to use, a few setup examples
are listed in the following sections. The main window of the software is shown below.

10
Assign a Pad to Start/Stop MMC
It can be easier to trigger a Pad to start or stop a song than to use the keyboard or mouse.
The following example sets Pad 7 to send a Stop message and Pad 8 to send a Start
message.
1. Click Pad 7 in the software to select it, then use the Mode pull down list box to set
it to Switched.
2. Use the CC Number pull down list box to set the value to 1, which is the MMC Stop
command.
3. Click Pad 8 in the software to select it, then use the Mode pull down list box to set
it to Switched.
4. Use the CC Number pull down list box to set the value to 2, which is the MMC Start
command.

11
Assign Pads to Send MIDI Notes
It is natural to lay down snare and kick drum notes when starting a song. The following
example sets Pads 1 and 2 to trigger Bass Drum and Snare Drum notes (MIDI note numbers
36 and 38 respectively).
1. Click Pad 1 to select it, then use the Mode pull down list box to set it to MIDI Note.
Use the CC Number pull down list box (which also controls the MIDI note number
when MIDI Note is selected) to 36 for the Bass Drum. Leave the other setting at the
default Gate value, which causes the note to end when the Pad is released. The
Toggle option causes the note to continue playing until the Pad is hit a second time.
2. Click Pad 2 to select it, then use the Mode pull down list box to set it to MIDI Note.
Use the CC Number pull down list box, which also controls the MIDI note number
when MIDI Note is selected, to 38 for the Snare Drum.

12
Assign a Pad to Toggle a MIDI CC# Between Two Values
One popular musical effect is to take an audio clip, filter it heavily for certain sections of
the song, then switch it back to the full open sound later in the song. The following
example sets Pad 6 to toggle two values for the Brightness filter (CC#74).
1. Click Pad 6 to select it, then use the Mode pull down list box to set it to Switched
and the Mode Option to Toggle.
2. Use the CC Number pull down list box to set the value to 74., which is the
Brightness filter.
3. Use the Min/LSB pull down list box to set the value to 78, which closes down the
filter part way, but still allows a lot of audio to pass through. Next, use the
Max/MSB pull down list box to set the value to 127, which opens the filter
completely to let full audio through.
Now, pressing Pad 6 toggles between the filtered and full audio settings.

13
Save Settings to a Preset
Once you have configured the SRP64 to your preferences, you should save the settings to
a memory slot for instant recall. In the following example, we will save the settings to
memory slot 2.
1. Locate the Send to Keyboard button on the right side of the software interface. Use
the Send to Mem pull down list box to set it to 2.
2. Click the Send to Keyboard button to save preset to memory slot 2.
Setting Pad RGB Backlighting
Each Pad can be set to any color by controlling the brightness of the red, green, and blue
elements. Perform the following steps to set the backlighting color for a Pad.
1. Click any Pad to select it.
2. Use the CR, CG, and CB pull down list boxes in the top right corner of the interface
to set the brightness for the red, green, and blue elements to a value between 0
and 127. 0 is minimum brightness (color element is off) and 127 is the maximum
brightness.
3. Once you have set the value for all three color elements, click the Send to Keyboard
button to send the selected color to the Pad.

SETUP IN ABLETON® LIVE™
Once you have connected the SRP64 to your computer, open your Ableton® Live™
software and go to the Preferences screen. Click the Link MIDI tab on the left to get the
following screen.
•In the MIDI Ports section at the bottom, click the Track button to the right of the
Input and Output options to set Track On, which enables the SRP64 as an Input
device to play MIDI tracks in Live and as an Output device to see the played and
recorded notes feedback to the Pad LEDs.
•Set the Sync option On for the Output to cause the Pad LEDs to pulse and flash in
time with your project tempo.
•Turning Remote On for both the Input and Output allows the SRP64 to be mapped
to parameters in Live and to see feedback of that mapping.

16
•Turning Track On for the SRP64 allows Live™ to playback and control any device
connected to the physical MIDI ports.
•When used with Ableton® Live, the 8x8 grid of RGB LED Pads will give intuitive
visual feedback on your clips as you launch, stop, edit, and record them. Conversely,
you can see these Pads on your Live screen inside a colored 8x8 rectangular "ring".
The color of the "ring" changes depending on which Control Surface choice is
selected in Live.
•Pressing a Pad on the SRP64 triggers a clip (if one exists) in the corresponding slot in
Live. However, pressing an empty clip slot on an unarmed track will stop clip
playback on that track. If the track is armed, pressing a Pad begins recording into an
empty clip slot.
•When used with Ableton Live, the top 8 buttons default as Scene Launch buttons,
which can be assigned to other functions, as desired. When used as Scene Launch
buttons, pressing the Scene Launch buttons on the right side of the SRP64 will
trigger horizontal rows of clips, also known as "Scenes". The buttons allow you to
launch, stop, and/or record multiple clips with one button, making them ideal for
live performances. As with the 8x8 grid of Pads, the Scene Launch buttons match
the scene colors on your Live screen.
•To play the session in Ableton Live, you have to set the device and channel for Light
track by 1) selecting W-P64 for the MIDI TO value and 2) selecting CH.6 for Channels,
as shown below.
If you find that features described in this manual do not function as expected, recheck your
MIDI port settings.
