SH101-M
All MIDI data coming to MIDI input of the interface are transmitted to MIDI-THRU/OUT output of
the interface unaffected
connected without additional MIDI Thru-Box. MIDI input of the other (next in chain) MIDI device can be
simply fed from MIDI-THRU/OUT output of the interface (see pic. 2).
If there are no other MIDI devices to be used, only MIDI-IN cable is necessary (from host system
to MIDI-IN input of the interface).

2.2. MEMORY BACK-UP SET-UP

The interface can transmit its own System Exclusive data. These messages are used for back-
up / recovery of the internal memory settings.
To back-up the memory of the interface, connect MIDI output MIDI-THRU/OUT to MIDI input of
the host system (PC, sequencer...) (see pic. 3).

Attention! Disable the MIDI ECHO, THRU functions of your sequencer in this case to prevent
communication loops that might "freeze" your MIDI system (see Appendix C.)!

3. INTERFACE OPERATION

The interface has a single manual control element – Reset button – which turns the interface to
stand-by status. All other functions are controlled by MIDI commands. Working status of the interface
is indicated by two-color (red / green) LED.

3.1. INITIALIZATION SEQUENCE

When the SH-101 is switched on, the reset sequence of the interface is executed automatically.
During this sequence, the system parameters are recalled from the system memory bank to the
system working buffer ([3] on pic. 4) and default values of preset parameters are stored in the edit
buffer (see table 2). The interface is now switched in the initial stand-by mode and it does not affect the
SH-101. The instrument can be used usual way like no MIDI interface has been installed. The interface
is now monitoring the incoming MIDI data. Accordingly to the type of MIDI data received the interface
is activated (see chapter 3.2 for Operation modes details).

3.2. INSTRUMENT CONTROL

After the reset of the interface (see above), all control elements of the instrument, including its
keyboard work normally. Interface's indication LED doesn't light and MIDI data are transferred from
MIDI input to MIDI-THRU/OUT output of the interface. The interface is prepared for receiving of an
acceptable MIDI command described in chapter 5. There are two basic operation modes available:
