9 FIRMWARE UPDATE
8 Filter Tuning
The T¨ o¨ or¨ o contains an analog FL A847 filter for each voice. According to the nature
of analog components, each voice will have slightly different sound. In order to minimize
these variations, the filter can be tuned via an automated procedure.
ˆ
Wait at least 15 minutes after the T¨ o¨ or¨ o has been powered up. This is to ensure
that all internal components are working at their desired operation temperature.
ˆ
Turn down the volume on your attached audio system or disconnect the output jacks.
While the tune procedure is running, some high pitched tones will be generated at
high output levels that could damage your speakers and hearing.
ˆ
Press and hold the SYSTEM button. Then press the module button labelled AMP .
This button also has a secondary vertical label TUNE left to it.
ˆ
The tune procedure is now started and will take about 2 minutes to proceed. While
running, the display will show some screens that represent the individual steps.
ˆ
After the tuning is done, the display will return to show the preset number again.
9 Firmware Update
To benefit from new features (and potential bug-fixes), the internal firmware of the T¨ o¨ or¨ o
can be re-programmed. Updates should only be performed when absolutely necessary and
the procedure steps and recommendations should be strictly followed.
In order to check which version of the firmware is currently installed, the display will show
the version number briefly right after the
T¨ o¨ or¨ o is powered on.
Important: Failing to observe the update procedure may simply brick your device!
Therefore, please proceed carefully.
To update your T¨ o¨ or¨ o instrument to the latest firmware revision , please refer to the
