Ok, folks, I have been reading the continuing quantizer thread(s) and
decided to settle it once and for all, at least scientifically...
I pulled out the oscilloscope and there IS both a delay and slew
(portamento) effect imposed by the QTKB. I initally set the TKB up to
alternate between min and max pot settings between stages and ran it
with a DTG at various speeds.
Results:
Delay: the QTKB adds an average 2-3 millisecond delay between input
and output.
Portamento: this is nonlinear so it's hard to quantify in ms/v but I
measured it takes ~10 ms to slew between values. The QTKB seems to
output a new value at ~2 ms intervals so there are bigger
"stairsteps" between TKB stages as you increase the pot values
between 2 stages. But, there is definiately a zippering portamento
thing going on here.
That's the view from the lab. I leave the debate as to the musical
implications up to you, the composers. I personally have no beef with
delay, but would like to see the portamento eliminated or minimized.
cheers,
Peff
