The kind of morphing that would work with MIDI is the straight-line path of superknob (not your finger) controlling the morph. Otherwise, I'm not aware of a MIDI way of transmitting or receiving 32x32 grid location.

I would probably start with the old legacy Performance Recorder and see if the morphing (finger position) is recorded and played back with that recording in MIDI mode. This would at least eliminate any chance of operator error in using Cubase. If this cannot document the morphing - then your best bet is to record audio unless superknob morphing works for you in which case MIDI should be fine.

Best way to record Smart Morph

what is the best way to record a moprhed FMX with an arp while moving around on the morph pad?

Record it as Audio to your DAW!

This has been something we have mentioned since the MONTAGE’s introduction four years ago, there are some things that you can do on the MONTAGE that must be recorded as audio. Example, using an external modifier within the Motion Control Synthesis Engine. Say you have your rhythm guitarist’s audio output connected to the AD In such that when they strummed a chord the audio pulse of that chord influenced the Modulation Index of your FM-X Pad. Because the modifier is external, it does not leave a MIDI ‘footprint’ that can be documented to the sequencer.

Traditional Vocoder performances cannot be documented as MIDI... Again because the microphone input does not create a MIDI ‘footprint’. The interaction must be captured to your DAW as Audio.

Motion Sequences themselves leave no MIDI ‘footprints’, they are themselves sequences that can be triggered, on demand, and are applied in real time to the tone engine — typically, they can be set in motion by either a Note-On, or an Arp, or by an external audio event...

What you can do...
What can be recorded involving the Smart Morph, is the direct movement of the Super Knob. Turning a Knob generates a stream of MIDI events.
Motion Sequences can be used to move the Super Knob, which in turn moves the active pixel back and forth on the Morph Map, but rules of triggering the Motion Sequence apply... (Note-On, Arp, AD In), the MSeq moving the Super Knob is not direct movement of the Super Knob and therefore, so leaves no ‘footprints’. You can record the trigger event which will trigger the MSeq during playback.

In general, live interaction with the MONTAGE does not always leave a documentable trail of MIDI events. There are going to be things that produce sound that cannot be recorded as MIDI events.
Similar reality: A DJ can create scribbles and scrubbing noises while playing back a vinyl record... but cannot record that interaction into the vinyl itself. They must apply it manually after-the-fact. “Scribbling” your finger on the Self-Organizing Map cannot be recorded as MIDI but can be documented by recording the Audio Output of Part 1
Hope that helps.

thank you, I wil try audio again, and see what happens to the tempo. superknob morph path is great, but only goes in a linear direction. can´t move all around the crazy sounding path.

This could be implimented in MIDI via NRPN: one number for X-axis and another for Y-axis.

Lots of things could be done - but I'm speaking for what's available.

As for the unavailable - I'd rather not use NRPN and would prefer CC or Sysex as these two methods are currently employed for most everything else in Montage/MODX. CC as a preference for universal support (MIDI controllers/gadgets, more straight-forward for DAW). Sysex would still be OK.
