I'll try to answer, to see if I my understanding is correct (especially
since I'm getting one of the next units!).

Your current setup can read MIDI, do any processing you program it to do
(using and/or processing the MIDI data, if desired), and it can send MIDI
messages.

The PSIM, on the other hand, has 4 analog inputs. These can digitize analog
signals, so your PSIM program can react to them (if desired). The PSIM does
not output MIDI (yet?) but does output 4 analog signals. I keep thinking of
them as CV outs, but these can be used as audio outputs (but there are
limitations, and this is not the PSIM's original purpose).

Analog signals that will be fed into the PSIM will typically include pitch,
gate, clock, EGs, and/or LFOs.
Analog outputs from the PSIM may be pitch (quantized, if desired), gate or
trigger, clock, envelope, LFO, and more.

Adding a hardware MIDI-to-C/V converter to your existing system would allow
you to generate CVs (control voltages) by sending MIDI from Max/MSP to the
converter. But you would lack the analog inputs.

So, bottom line: Your current setup is more MIDI-oriented, whereas the PSIM
is more CV-oriented. (Future expansion may change this.)

How did I do, Brice?
