[LUG] [GEN] MIDI input to plug-in instruments bypassing the sequencer

"Dave Dever <daviddever...>" <daviddever...>

Using Logic Gold 5.3 under OS 9 on the Mac, I am having a problem routing
MIDI note information directly from a physical input (AMT8 USB, built-in
MIDI drivers only) to the EXS24 plug-in, running as an ASIO Audio Instrument
object (Delta TDIF). The intended function is to use the EXS24 as a
dedicated drum sampler INDEPENDENT of the sequencer, i.e., without requiring
that the channel strip for the EXS24 be selected in the Arrange window.

Is this possible with plug-in instruments?

I have carefully verified the MIDI channels of the input controller and the
plug-in instrument object itself; the Monitor objects show that MIDI note
information is reaching the plugin from the physical input AND from a set of
fader objects (buttons with feedback, set to pass Note Ons) that feed the
plugin. 

I've created a special fader object (Channel Switcher) which switches
between destinations (feedback note-on buttons routed to an external MIDI
module), or a duplicate set routed to the EXS24).

When selecting the Channel Switcher object in the Arrange window, I can play
the external MIDI module from the controller without any difficulty, as well
as playing the note-on buttons on screen; setting the switch to the EXS24
position generates no sound, even from the note-on buttons behind it, which
are cabled directly to the object.

I've even tried routing MIDI from a dummy object OUT of the interface and
back into a dedicated physical input connected DIRECTLY to the EXS24, with
no success.

Is this a fundamental limitation of the way plug-in instruments respond to
MIDI in Logic? Are the plug-in instruments exclusively under the control of
the sequencer?
