The active tone can be selected manually from the device panel anytime (by or buttons) or via Program
Change / Bank Select MIDI commands in dependence on system parameters setting. When a tone is set as
active from the controller, data from corresponding part of tone bank are copied to tone edit buffer
⑧ and
then transferred to controlled instrument as SysEx messages
⑨ . When a tone is set as active from controlled
instrument, data from corresponding part of tone bank are copied to tone edit buffer
⑧
and they can be
simultaneously sent to the controller as stream of CCs
⑩
.
Control Changes (CCs) MIDI commands received from the controller

are divided to assigned (by an
instrument parameter) and unassigned to a tone parameter. Assigned CCs are converted to control SysEx data
and then sent to the instrument

on setting of system parameters.
SysEx messages incoming from the controlled instrument
⑨ can be converted and sent to the controller as CCs
⑩ in dependence on setting of system parameters.
Direct Control MIDI SysEx commands (i.e. Bulk Dump Request and Initialize)
⑭ are processed by CPU of the
SAVVY immediately after their receiving. Please see description of SysEx communication.
All other MIDI commands (i.e. unused channel commands, all common system commands and unacceptable
SysEx) are only transferred through the editor without any change

ACKUP BATTERY REPLACEMENT
The SAVVY device’s internal memory is powered from battery cell when the device is disconnected from power
supply adapter. The battery has a life of about five years. The battery should be replaced after this time or
when its voltage falls under 2,7 V . For replacement, use standard lithium battery cell CR2032
CR2032CR2032
CR2032 type (lithium).
The battery is placed on PCB inside the device. So it necessary to open the device.

HARDWARE TESTS HARDWARE TESTSHARDWARE TESTS
HARDWARE TESTS
The SAVVY device’s basic software (BIOS) contains routines for checking of functionality of its own hardware.
Testing procedures can be executed if display of the device doesn’t show correctly for example or if the device
does not work properly with MIDI system, etc.;

Standard MIDI cable (with DIN 41524 connectors on both ends) is necessary for execution of this testing
routine. Individual MIDI inputs and outputs of the device will be interconnected with help of this cable.
The test is indicated by symbol “M.

arbitrary MIDI input with arbitrary MIDI output is indicated by symbols of two characters. First of them
indicates used MIDI output (“i
