Yes, in a much more primitive form. The A-112 has no high-speed VCO (like
the BBD modules) but a software generated clock. Thats not as smooth and
fast as a high-speed VCO that generates the delay clock. And there is no
pure delay possible with the A-112 as it's not possible to turn off the
output DAC during a write operation into the A-112 memory. That's why there
is a remark that the additional effects should be treated "in a way free of
charge" for the A-112.
