[PD] examples of classic Sample and Hold

[Pagano, Patrick]

Thank you everyone,  Bill yours is that classic S&H sound i was looking for I did randomize the osc~ too and it sounds even better like you suggested

the line~ helps alot too.

for sample-and-hold, as it is usually implemented for pitch in a synth, you actually don't even NEED to use the samphold~ object!  you can just use a metro to simulate the clock, and then a random to simulate the noise input (that's what was usually used for synth sample and hold madness).


[metro 125]
|
[random 5000]
|
[/ 100]
|
[+ 40]
|
[mtof]
|
[phasor~]
|
[*~ 2]
|
[-~ 1]

likewise, you can use the same process for sample and hold on a filter by just adding a short [line~ 10] after the [mtof] and feeding that into the 2nd inlet of [vcf~]

or of course, you could run one process on the pitch and another on the filter, but just make sure to use a slightly different random number base to make them independent,

As I understand it, a classic sample and hold
is capturing the instantaneous input voltage
of an incoming signal, and remembering it.

The [metro 5] is also banging on the [snapshot~]'s hot inlet
with [adc~] if want samples at 5ms intervals.

However, these days, in my own mind at least,
I think about "sample and hold" as meaning,
"read a few seconds of audio from a source
into a memory, and loop it."  I don't know if others
think this way also.

That would be a more complex circuit.

Hello Everyone


I am wondering if people would be willing if they have an example of Sample and Hold to use for a project i am working on.

I am interested in the classic sounding Sample and Hold insanity please share a patch if you have one so i may learn on how to make one properly

the one in the help files is not the kind i am talking about


i hope this makes sense
