Issues during Firmware Upgrade Process
If you have any problems during firmware upgrade pro-
cess, please proceed as follows:
• Disconnect the Rocket from the USB connection.
• Press and hold the MIDI Channel Selection button
6
of the Rocket.
• Reconnect the USB connection of the Rocket.
This starts the Bootloader mode automatically.
• Send the firmware again. Follow the instructions
of the previous chapter.
Filter Calibration
The analog filter of the Rocket is calibrated at the factory.
Tuning is very stable over a wide temperature range, so it
is not necessary to use this function frequently:
•
The Rocket will generate high-volume output
during calibration, so turn headphones volume
down as well as the volume of your speakers or
alternatively disconnect the audio output.
• Disconnect anything connected to the VCF input.
• Switch Filter Type to LP.
• Switch Boost to off.
• Send the MIDI tune request 0xF6 with a suited
MIDI software to the Rocket.
• Calibration progress can take up to 30 seconds.
The Launch button LED will light up in a dimmed
mode while calibration is in progress.
