Dieter,

the main point of the ASR is that one very clock pulse, you get a different value on *all* outputs, with all outputs with a number greater than 1 showing the "history" of the input CV. The A-152 will hold the last value on each destination defined at the point that that stage became inactive. So the output value of a stage is updated only when it becomes active. Very different from an ASR.

One usage example of an ASR is routing a melodic CV sequence to a number of VCOs --- think "canon": the same melody played by all vcos with one sequence step delay between them. 

Actually I think that an AD/DA based ASR with quantisation options and perhaps 8 or even 16 stages & outputs could be a very successful module.

Best,
Denis Goekdag
