Testing Steps
1. Insert the test iPad into LDT1 and connect the iPad to the LDT1 using the appropriate
lightning or 30-pin adapter. Connect the power adapter to the LDT1. Confirm that the
LDT1 Main Volume is set to MAX. (100%) Connect the Hi-Hat controller pedal to LDT1
using the TS cable.
2. Power the unit on. Confirm that all of the information listed below is correct in the
“Settings” App (in the “General” > “Alesis DM Dock” tab).
Manufacturer Alesis
Model Number DM Dock
Firmware Version 0.0.12
Hardware Version 0.0.1
This step confirms that the PSOC firmware is successfully installed.
3. Open the LDT1 test app. Press the “Reset App” button in the top left corner of the
screen.

4. Confirm that the LDT1 test app has connected to the LDT1 and is showing “Device:
Found” in the bottom left corner of the screen. It may also show the correct firmware
version (V1.02) or it may say “Detecting FW…” in the bottom left corner of the screen,
as shown in the pictures below.

5. Using the Y cable, connect the 2*TS connectors to the Main Outputs (Left and Right),
then connect the TRS connector to the 01 Kick Input.
6. Wait until the text below the back button says “Ready”, as shown in the picture below.

7. Press “Send Pulse” and confirm that the “Kick Tip” and “Kick Ring” boxes turn green,
as shown in the screen shot below.
8. Repeat this test for all trigger inputs so that all “Tip” and “Ring” buttons turn green.
When the test is complete, the LDT1 test app will return to the main page, and “Trigger
Input Test” button will turn green, as shown in the screen shot below. Otherwise, the
test has failed.
9. Remove the Y cable from the unit.
10. Press the “MIDI Test” button. Then, use the 5-pin DIN MIDI cable to connect the MIDI
input to the MIDI output of LDT1. Press the “Start test” button. If the test passed, the

app will return to the main menu and the “MIDI I/O Test” button will be green.
Otherwise, the test has failed.
11. Remove the MIDI cable from the unit, and then connect the LDT1 to the computer by
using a USB cable. Open the MIDI-OX software in the computer and set the routing as
shown in the picture below:
12. Press the “USB MIDI test” button to enter the USB test page, and then press the “Start
test” button. If the test has passed, the app will return to the main menu and the “USB
MIDI test” button will turn green. Otherwise, the test has failed.

NOTE: Steps 13-17 are not required if the firmware version (v1.02) appeared
correctly in the test app in step 4.
