Akai S950 Operator's Manual page 57

The next page is concerned with the 5950's ability to be controlled using the
RS232 muitipin port found on the rear of the unit. This allows the S950 to be
controlled by computer for sample editing, etc., instead of MIDI.
The display for this page rends:
This is the default setting and the display shows that the 5950 is set for
MIDI operation. To control the 5950 using the RS232 port, you must move the
cursor one position to the right using the 'cursor >' button and select '2'
using the CONTROL knob or the keypad. It is necessary to match the 5950's
RS232 baud rate to the computers and this is done by moving the cursor to the
'RS232 Baud rate' field and inputting data using the CONTROL knob or the blue
keypad. The 'ACTUAL' field displays the incoming signal's baud rate. If it is
more than +/-2x different from the intended Baud rate, you may have problems.
For further Information on the RS232 protocol used on the 5950, please refer
to your local Akal dealer or to your countries distributor who will supply
you with the relevant documentation.
That concludes our examination of the MIDI pages. Once again, as in all modes
of operation in the S950, the default settings of these pages have been
sensibly chosen and it is quite likely that you will not have to change them
and probably the only MIDI function you will need to change is the MIDI
Channel receive number and the OMNI ON/OFF selection on Page 01.
TROUBLE SHOOTING
There is not much in this mode that can cause problems and, more often than
not, these pages will be used to actually solve any MIDI problems you may
have.
The mast basic MIDI problem you will encounter is that,, despite the'jfact
the your MIDI connections seem to be correctly set up, you are not getting a
sound. To check on this, the following procedure is recommended.
Firstly, go to Page 03 - the incoming MIDI data monitor and play a few notes
on the connected MIDI controller. Make a note of the incoming data and go
back to Page 01 using the Page up button. Here, check that the MIDI receive
channel is set to match the channel being transmitted by the controller or
that OMNI is switched to ON. If everything matches up o. k. and you are still
not getting a sound, then the problem is more likely to be with the audio
side of things (l. e. a broken lead, faulty amplifier, volume turned down,
etc.).
If you are using a MIDI controller that transmits MIDI control 7 (volume) go
to Page 04 to check whether or not the 5950 is set to respond to this. If it
is set to ON and you are getting no sound, it could be that your keyboard has
remotely turned the 5950 down with its MIDI volume control.
If you are not able to use pitch bend on the 5950, check 'that the pitch bend
wheel range on Page 04 is set to something, other than 00. If it is, then the
fault lies in the MIDI controller.
