ну скажу честно) в лоджике не ставил, в кубейсе все отлично справляется с задержками. У тебя появляется на микшере дополнительные каналы куди и ставишь обработку. В Лодже тоже есть, как там идет компенсация задержки незнаю не пробовал, но думаю все должно быть нормально.
блин что то файл не прикрепляется, Короче там где ты выбираешь синты типа EXS24 ипр есть также external instrument . а там уже выбираешь входа звуковухи
ПС)) Processing External MIDI Instruments With Effects
You can route external MIDI sound generators through the Logic Pro Mixer, allowing
you to process them with Logic Pro effects. This is achieved through use of the External
Instrument plug-in. Ideally, you will use a multi input and output audio interface, to
avoid constant re-patching of devices.
To process external MIDI instruments with effects:
1 Connect the output (or output pair) of your MIDI module with an input (pair) on your
audio interface.
Note: These can be either analog or digital connections if your audio interface and
effects unit are equipped with either, or both.
2 Create an instrument channel.
3 Click the Instrument slot, and choose External Instrument from the pop-up menu.
4 Choose the MIDI Destination from the menu in the External (instrument) plug-in
window.
The MIDI Destination menu will show all sub-channels of all multi instruments in the
Environment.
5 Choose the input (of your audio interface) that the MIDI sound generator is connected
to from the Input pop-up menu.
6 Adjust the Input Volume, if necessary.
7 Insert the desired effects in the Insert slots of the channel.
As the track is routed to an instrument channel (which is being used for an external
MIDI sound module), it behaves just like a standard software instrument track, which
means that you can record and play back MIDI regions on it—with the following
benefits:
 You can take advantage of the sounds and synthesis engine of your MIDI module,
with no overhead on your Macintosh CPU (apart from the effects used on the
channel).
 You can use insert effects, obviously, but can also use Send effects by routing the
Instrument channel to aux channels.
 You can bounce your external MIDI instrument parts—with or without effects—to an
audio file, in real time. This makes the creation of a mix, inclusive of all internal and
external devices and tracks, a one step process.
Note: You can not use the Freeze function on such tracks, nor can you perform an
offline bounce.
