How do I connect more than one sound module to my Korg i30?


You have already figured out that you need to connect the

MIDI OUT of the Korg i30 to the MIDI IN of your first

sound module using a MIDI cable. You can expand this chain,

by connecting the MIDI THRU of the first sound module

to the MIDI IN of the second sound module.


[i30] OUT IN [Module #1] THRU IN [module #2]


The MIDI THRU port simply passes a copy of the

MIDI signal that it receives in the MIDI IN port.

You can have Module #1 to respond to MIDI channels 1,2,3,4

while Module #2 receives on MIDI channels 5,6,7,8.

This allows you to play certain parts of an arrangement

via sound module #1 while other parts can by played back

by sound module #2.


Most sound modules can operate in Multitimbral [Multi] mode.

They can simultaneously receive on 16 MIDI channels and you

have the option of setting each channel on or off.


You can use this trick to cascade a series of sound modules:


[Module #2] THRU IN [module #3] THRU IN [module #4]


If you are planning to have a monster setup with 8 or more

sound modules, it is better to use a multiport MIDI patch

bay like the Emagic AMT8


[i30] OUT IN1 [amt8] OUT1 IN [module #1]

[amt8] OUT2 IN [module #2]

[amt8] OUT3 IN [module #3]

[amt8] OUT4 IN [module #4]

[amt8] OUT5 IN [module #5]

[amt8] OUT6 IN [module #6]

[amt8] OUT7 IN [module #7]

[amt8] OUT8 IN [module #8]

The big advantage of this scheme is that you do not have

to deal with the latency that otherwise happens by cascading

multiple modules. The AMT8 acts like a MIDI hub and routes

the MIDI data to each individual sound module with a direct link.



What happens if I have more than 8 modules?


In that case, you can connect a second AMT8 in series

with the first AMT8 to make a 16IN x 16OUT MIDI patch bay.



[i30] OUT IN1 [amt8 #1] [amt8 #2] PC/MAC.


Another advantage is that the AMT8 can interface to your

PC/Mac via the serial port or the USB port. You can use your

favorite software sequencer like Sonar or Logic to control

your sound modules.


Yet another advantage of the AMT8 is that it has a multiclient

driver. This means more than one application can access the

AMT8 at the same time. In other words you do not have to

exit Sonar in order to run your favorite MIDI librarian like

MidiQuest or SoundDiver. As many as 8 AMT8 units can be chained

in series to give you a 64IN x 64OUT MIDI interface!


If you think you may be using more than 3 AMT8 units, it is

a good idea to use Emagic Logic as your software sequencer.

Emagic Logic and the AMT8 support Active MIDI Transmission (AMT)

protocol. This eliminates the latency associated with chaining

multiple MIDI interfaces. Each MIDI event is time stamped, buffered

ahead of time and send simultaneously across the MIDI ports.

AMT technology allows for far tighter MIDI timing.


As you can see, with a rack of sound modules and a couple of AMT8

interfaces linked to a computer running a software sequencer, you

have access to a whole wide world of possibilities only limited

by your imagination. The best way to learn and explore is to

hook it up and start experimenting.


Good luck,
