7.1 Software Update
The Neutron DFU (Device Firmware Upgrade) updater can be downloaded by
going to www.musictri.be
Please follow the steps documented in the release notes accompanying
the update.
7. 2 Assign Out Calibration
This calibration has been carried out by the factory at the manufacturing stage
but instructions are described here if needed.
For this, you'll need a 3.5 mm mono patch cable, a digital voltmeter, and MIDI-OX
installed on your PC.
1. Insert the patch cable into the ASSIGN output on the Neutron front panel.
2. Run MIDI-OX on your computer. Go to OPTIONS > MIDI DEVICES.
3. Select Neutron as the MIDI IN and MIDI OUT
4. Make sure "Pass SysEx" at the bottom of the Options drop-down menu is
ticked.
5. In the VIEW menu, select SysEx...
6. In the Command Window, enter the SysEx command to be sent to the Neutron.
For ASSIGN out calibration at 1 V, the command is: F0 00 20 32 00 7F 10 20 F7
7. In the Command Window drop-down menu, select Send SysEx. The Sysex
command will be sent to the Neutron. Both 8' octave range LEDs will be ashing
to indicate the Neutron is in ASSIGN out 1 V calibration mode.
8. Measure the voltage on the patch cable attached to the ASSIGN out and adjust
until it reads 1 V +/- 0.001 V.
9. To increase the voltage send the Sysex command F0 00 20 32 00 7F 10 23 F7.
To decrease the voltage, send the Sysex command F0 00 20 32 00 7F 10 22 F7.
Repeat until the voltage reads 1 V +/- 0.001 V. Then move on to step 10.
10. Send the Sysex command for ASSIGN out calibration to the Neutron at 4 V.
The command isF0 00 20 32 00 7F 10 21 F7.
Both 32' octave range LEDs will be ashing to indicate the Neutron is in ASSIGN
out 4 V calibration mode.
11. Repeat step 9 until the voltage reads 4 V +/- 0.001 V. Then move onto step 12.
12. Save the calibration data and exit calibration mode by sending the Sysex
command F0 00 20 32 00 7F 10 24 F7.
The Neutron will return to its normal operating mode.
