MIDI Solutions MIDI Delay
Operating Instructions
MIDI Solutions MIDI Delay delays all MIDI messages by a preprogrammed delay time from 0 to 1023 ms. MIDI Solutions
MIDI Delay is powered by the MIDI signal and requires no batteries or power supply to operate.
CONNECTIONS
Connect the In of the MIDI Delay to the MIDI Out or Thru of the sending MIDI device using a standard MIDI cable. Connect the
Out of the MIDI Delay to the MIDI In of the receiving MIDI device. It is recommended that the number of MIDI Solutions
products chained together between any two MIDI devices be limited to four.
OPERATION
The MIDI Delay's MIDI Indicator LED will light as soon as the sending device is turned on, and flashes whenever MIDI
data passes through the unit. All MIDI messages are delayed by the preprogrammed time.
PROGRAMMING
The delay time is programmed by sending the unit the following System Exclusive message:
F0 00 00 50 13 01 aa bb F7 (values in Hex)
where aa = 128 ms delay increments ( 00 < aa < 07 )
bb = 1 ms delay increments ( 00 < bb < 7F)
The message contains two values, aa and bb, that combine to specify the total delay. aa adds to the delay time in 128 ms
increments, and bb adds to the delay time in 1 ms increments. For example to specify a 300 ms delay requires 2 x 128
ms increments + 44 x 1 ms increments = 300 ms total. All values must be entered in hexadecimal (see table below), so in
this example aa = 02, and bb = 2C. Upon receipt of the System Exclusive message, the MIDI indicator LED will flash
rapidly for about one second to indicate that the setting has been stored. The setting is retained in memory until
reprogrammed with a new setting.
EXAMPLES
100 ms delay = 0 x 128 ms + 100 x 1 ms
127 ms delay = 0 x 128 ms + 127 x 1 ms
128 ms delay = 1 x 128 ms + 0 x 1 ms
129 ms delay = 1 x 128 ms + 1 x 1 ms
200 ms delay = 1 x 128 ms + 72 x 1 ms
255 ms delay = 1 x 128 ms + 127 x 1 ms
256 ms delay = 2 x 128 ms + 0 x 1 ms
257 ms delay = 2 x 128 ms + 1 x 1 ms
300 ms delay = 2 x 128 ms + 44 x 1 ms
400 ms delay = 3 x 128 ms + 16 x 1 ms
500 ms delay = 3 x 128 ms + 116 x 1 ms
