4. A-100 Basic Systems
It’s not in the nature of modular systems to have hard
and fast rules about which modules should be inclu-
ded. But if you’re just starting out along the modular
path, it may be difficult to choose a sensible first set of
modules. Accordingly, we’ve designed Basic Systems
with all the modules mounted in a rack system, and 30
patch leads thrown in as well. For an exact run-down
of the modules included in Basic System 1 (A-
100BS1), see the table on the right of this page, and
the illustration on the next page. To integrate BS1 it
into a MIDI system, you would need a separate MIDI
interface, such as an MCV4 or MCV24. In the Basic
System 2 (A-100BS2) the MIDI interface A-190 is
included (instead of A-150 and A-162). We also have
available a small Mini System (A-100MS). See our
topic prospectus for details.
The purpose and function of other modules will be-
come more apparent as you work with your system,
and you will be able to decide which extra modules you
need for your particular purposes.
In the future other types of complete systems may be
available. We are planning an Expansion System con-
taining nearly all modules not included in the Basic
Systems, a Vocoder System and a Sound Processing
System without VCO’s for external audio signals.
