Subject: Morph versus cross-fades

<<Sorry, a bit under the weather this week. Headaches and nausea>>

In my little dream-world, the MOTM-130 doesn't 'morph' in the true sense. It
'cross-fades', meaning the
output is an equal-weighted average of the inputs. ie

Vout = x(V1) + (1-x)V2

where x goes from 0 to 1. In other words, a pan pot.

Morphing implies there is a 'Hamming distance' (in crypto-speak) taken into
effect. In other words, you can have
different 'curves' along which the change occurs. The 'pan-pot' curve ( a
1:1 linear ratio) is one of many a 'morph'
could travel.

So, I propose the SHAPE knob of the MOTM-820 VC Lag is more of a 'morph'
function.

We've all seen the 'transform the girl's face into a tiger' sort of
graphical morphing.

I suppose JH's Scanner, fed by 'warped' voltages is a morpher (sp?).

What everyone has ∗assumed∗ is that the MOTM-130 can pass DC control
voltages as well as audio. Hmmmm......JH and I
will have to get back with you on that :)

Now, you ∗can∗ feed a 'warped' CV into the '130 as well, come to think of
it. So, the '130 is a 2-channel fader & morpher.
The panel pot for fade/pan is linear, but the CV in can be whatever.
