Default Novation Ultranova synth timing issues with Reaper

Good evening,

Issues similar to mine have been discussed throughout the forum and I apologize in advance but if anyone could offer any advice it would be greatly appreciated.

My ultranova is connected to Reaper via usb and the ultranova also acts as my audio interface which I have conservatively set at 10ms of latency. There is an editor that accompanies the ultranova's hardware synth, which can be utilized as a VST, but it does not generate sound but allows the user to alter the hardware synth's parameters on screen in the DAW.

In order to play the synth, via Reaper, the editor must be opened as an FX and record enabled but then a subsequent audio track must also be created, and also record enabled, so that the midi is sent to the hardware device and audio brought back into Reaper to be recorded, and heard, in Reaper.

I have the ultranova's audio interface settings so that it is 100% from host, (as in the hardware synth being played back is, "sounding thru" Reaper and not, "live.")

When tempo based effects are engaged with the ultranova synth, (LFO / arp / delay etc) the synth does not play back in time with the content material in reaper, (drums, samples , vst synths etc.) When the material is recorded it can be shifted so it is perfectly in line but this is annoying when auditioning sounds. Eventually Reaper and the synth do sync but it is arbitrary when and how this occurs.

I have tried the following to no avail:

1. Disabling the, "Use audio driver reported latency feature" in recording settings and manually inputting offsets, (this has the effect of offsetting both the midi and audio return track when record enabled and generates timing conflicts.)
2. Attempting to, "Offset output to this device" in Midi output configurations seems to have little effect.
3. Using Reainsert to avoid the latency issued presented has delivered minimal results.
4. Preserve PDC monitoring again, to my mind, produces inconsistent results.
5. Adjusting the manner in which the ultranova receives its clock source, (internal or from host) delivers minimal results.

The obvious thing would be to just record the audio live into Reaper but then automation or other effects cannot be applied.

As a preference I would prefer to, "hear" the ultranova in time and then have to adjust the recorded material accordingly but I just can't figure out how to do this. In a perfect world I would hear the synth in time and it would also be recorded in time but this may be a pipe dream.

If anyone could take a moment to respond I would be very grateful.
