To be honest I never really grasped the concept of the soundmap so I'm not sure if this has been possible with it: to morph from one preset to another programmatically from the DAW. Say, start with preset A at bar 1 and morph to preset B betwwen bars 14 and 16. That's what I would call a musical result.
No, that's not the purpose of it. The purpose is to create new sounds by combining up to 4 other presets.
In just the base sound map screen, you can click anywhere and drag, and it'll grab the 4 nearest presets and combine them "in some way" depending what direction and how far you drag. Instant new sound, without any knob tweaking.
The other way to use it is to select a preset and "save" it into one of the 4 slots at the top of the Sound Map screen. Once you have more than 1 of the slots filled, you go into the "Preset Morpher" view, where you can click and drag to adjust how the presets are "mixed" .. in real-time. Which is to say, if you play your keyboard AND click-drag in that screen, the sound will change in real-time.
Also, using this method, you can morph between 4 presets that are widely separated in the Sound Map screen. Just doing it in the Sound Map screen itself only grabs the nearest 4 presets, and it doesn't change the sound in real-time, only after you release the mouse.
I suppose you COULD set your DAW to record, and then just go about tweaking sounds in the Preset Morpher. .. hmm ... I might actually have to try that
@jackn2mpu -- while I too wonder how they managed to determine how many people actually used this function, I doubt that their decision to not implement has anything to do with technical ability. More likely it had to do with time constraints.
