I have heard that before, but can you tell us the difference Bakis?

Hi Richard,

the A152 selects between several Sample&Holds. Tha means: S&H stage one 
is filled, then the address goes on and fills the second S&H stage and 
so on. The value in the first S&H stage stays the same.

A shift register hands over the values from the first S&H stage to the 
second S&H stage and then fills the first stage with a new value.

That's true. But to make it still more complicated: for certain applications
the A-152 can do the same job as an ASR. If you think e.g. of a four VCO
patch with the CV inputs of the VCOs connected to four outputs of an ASR. If
an ASR is used the incoming CV is shifted with each clock to the next output
of the ASR which results in four different frequencies of the VCOs. If the
A-152 is used the audible result is the same although the voltages are not
shifted but only assigned to the S&H/T&H outputs. The difference in this
application is that the same frequencies are generated by the VCOs but with
different assignment of the frequencies to the VCOs.

And the A-152 can patched as an "real" ASR too but with one output only. For
this the S&H outputs have to be patched to the switched I/O sockets and the
common switched In/Out has to be used as shifted analog output. It depends
upon the patches between the S&H outputs and the switched I/O sockets if it
takes one, two, three ... clocks after the incoming CV appears at the common
output.

Not easy to understand at first glance but it works.

Best wishes
Dieter Doepfer
