Yes. Setting up multi-channel MIDI is a common workaround that makes a non-MPE synth behave as if it supported MPE. It does require some manual setup, though, and editing this MIDI data afterwards may not be very comfortable.

The idea is to copy the same sound as many times as the polyphony you want. Each copy plays only one note and is set to respond to only one MIDI channel. This lets you shape every aspect of the sound independently for each note.

You can do this in two ways: either duplicate the same instrument track several times in your DAW, or, if your plugin has a multi-channel/multi-timbral mode, duplicate the same sound within a single instance of the plugin.

On the Osmose side, select Multichannel MIDI mode, then set the range of MIDI channels to be used, for example channels 1 to 6 for six voices of independent polyphonic expression. The Osmose will then send each new note on a new channel.

As a side note, the Osmose's Multichannel mode also works for controlling synths that support the so-called MIDI Mono Mode, originally used for MIDI guitar applications.
