Use this cycle gadget to indicate which handshaking protocols are used
by your synth.
NO HANDSHAKE: Synth does not use handshaking.
ROLAND RQ1 RQD: Roland RQD shaking will take place using ACK, DAT,
ERR and RJC messages. Don't be concerned with
entering the ACK, ERR and RJC. They happen behind
the scenes. Just enter the RQD msg on the center
line of the GET command. Then move to the SEND
command and enter the WSD msg on the First line
and its DAT msg on the center line.
-OR-
Roland RQ1 communications will occur if you enter
an RQ1 msg on the center line of the GET command
and a DT1 msg on the center line of the SEND
command.
CASIO CZ SHAKE: Casio CZ handshaking will take place.
SIMPLE SHAKE: Simple handshaking just might suffice for a synth
who's handshaking scheme is not directly supported.
GET FROM SYNTH - A preparation command may be
entered on the "First" line in the Driver Creator
window. The command that actually requests the
data must be entered on the center line. After
the center line command has been sent, this hand-
shaking method will expect a short acknowledgment
message (ending with an F7) in reply. After the
acknowledgement message has been received, the
command entered on the "Last" line will be sent,
and it is expected that the synth will send the
requested sysex data.
SEND TO SYNTH - Use the "First" line in the Driver
Creation window to enter the command which notifies
your synth that you want to send it data. After
this command is sent, this handshaking method will
expect a short acknowledgment message (ending with
an F7) in reply. After the acknowledgement is re-
ceived the command entered on the center line will
be sent, and it is assumed that this sysex packet
will contain the data (-D) that you want to send
to your synth. A follow up command may be entered
on the "Last" line.
BANK ITEMS USE -P: NO handshaking! However, bank items are sent
and retrieved one item at a time. The -P (patch
number offset) is initialized to the Patch Min
value and is incremented for each subsequent SEND
or GET.
ROLAND RQ1 BULK: Use this method of communications for Roland
synths which return more than one sysex packet
when you send them one (1) GET command.
