The way I arrange my DSP is really pretty basic.
Load all audio source plugins that I want to use first.
Add any effects or other plugins in the order that I plan to connect them.
Add any output plugins last.
(possibly add peak plugins at various points to check signal levels as the last step).

I am not sure that I want to abuse the free image hosting services too much, to show intermediary steps that can just as easily be explained with words. Also, since I start with a clear DSP, you can easily see the order that I load the plugins by the number (in square brackets) assigned to the plugins in the DSP window.

For what you want (as I understand it):

You want to monitor from the host software. I would use ASIO (0/1) for this, which means a ProFX:SRC plugin set to FxBus (0/1) is needed. Since FxBus (0/1) is also the default for Wave audio output, it can also be used (to hear) for playback of the mixdown, etc.

You want to record MIDI soundfont output (kX Synth output), which means a ProFx:SRC plugin set to FxBus (2/3) is also needed.

You want to record from Line In, which means the ProFx:ADC plugin, with Line In selected as the record source, is needed.

That takes care of the audio sources. I would load them first (the order does not matter).

Now for the effects:
From your first picture in this thread, the APS Compressor is the first effect (it is the closest in the chain to an audio source), so that is the first effect I would load.

You want to use the APS Reverb which has no Wet/Dry mix controls, so I would use this in a send type of setup. For this I need a plugin to control the amount of signal that I want to send to the effect. I would use a simple St Vol plugin for this (this is the next plugin I would load). Then I would load the APS Reverb plugin itself. Next I need something to mix the dry part of the signal with the part of the signal that had the reverb applied to it. I would use a Stereo Mix plugin for this (this is the next plugin I would load).

You want to use the DelayB plugin which does have Wet/Dry mix controls, so I would probably use this as a simple insert effect (you really need to play around with all the possibilities to figure out how you prefer to use these effects). This is the plugin that I would load next.

You did not mention anything about any effects on the MIDI signal, but if you wanted to add effects there I would load all of them next (in the order that they are to be connected).

Next, since ProFx:kxlt does not have any volume controls, I would want something to be able to control the volume to my speakers. I would probably use a GainHQ plugin for this, so that would be the next plugin I would load.

The outputs:
To get the signal to the speakers we are using ProFx:kxlt, so I would load that next.

To get the signal to the OS (and your host software) to be recorded using ASIO, we need the ProFx:ASIO pluguin, so I would now load that.

That is pretty much it. Add some peak plugins if you want to check the signal levels at any point in the DSP.

I am using ASIO 4/5 for recording Line In, and ASIO 6/7 for recording MIDI. The pins that I connected to on ProFx:ASIO are the ones that correspond to those ASIO channels (currently) on my card.

I assume that you know how to configure your host software for what you want to do.

This is just one possible config, there are many ways it can be done.
