200e

Hi folks, the nearest thing to S&H on the 200e I can find is the FIX button on the 250e. Seems this button requires manual operation though.

It would be great to be able to route a pulse to that section to trigger a FIX. 

Or maybe by overloading the fix button, two options could be made available: manual and auto.

The thought of having four sample and holds in the 250e (from the external inputs), with each selected at the stage knobs (current functionality with manual S&H) is awesome.

Am I missing something? 

Thanks,
Doug

Thanks Jon. I see now too that one could set up all the stages on the 250e to have desirable consequences, then use the strobe mode to effectively S&H to a quantized result.

Great wikipedia page I had not yet consulted.

you can (mostly) do it with a 266e, see these two write-ups for the  
details and caveats:

hm if that 266e function is reducing the voltage range it's a bug. subject
to questions of course like is it reproduced on other units? is the same
effect for all input voltages? etc.  (but look on the bright side, it's
microtonal)

cause yeah, the idea is that you can indeed use the bottom section for S+H,
as in the 266 of old, with additional constrained uncertainty.

you're right about the 250e not having a pulsed S+H... i think it is an
interesting feature idea to toggle a field in strobe mode that would fix the
voltage of a stage when you strobe to it.

though, what happens now when you advance to a new 250e stage with
interpolation and external sampling? i don't have one in front of me.

i also think there are other ways of achieving glissandos, btw... most
easily with a 255 section.

Only an "OK" page, IMO. I would love to see more people get involved  
with writing/restructuring it. I've done a little, but it could really  
use a lot of work.

Thanks folks for the input. I managed to get S&H working using the 266e and the strobe feature on the 250e, plus I tried using the 291e to FM the 261 oscillators together. Great results all around.
