[sdiy] Monosynth features poll

[cheater cheater]

Rather than the randomness, it's about the immediate feedback between
what my ears hear and what my fingers feel (the physical position of
the key and vibration from the mechanism of the key)

The fact that the scanner makes the gate digital (on/off) and usually
adds a debouncing treshold removes a big part of this.

The minuscule delay from slow scanning circuits is another thing that
removes even more of the tangibility of sounds created with the
keyboard.

Midi is terrible.

All those three points prove to me that 'instant' is light years away
from 'almost instant'. Maybe if the scanner worked at a 10 mhz rate...

BTW, you don't need to slow down your scanner to make velocity work..
just think about it.
