[sdiy] trying to understand appregiators in late 70's synths

[johnspeth at yahoo.com]

While I haven't surveyed synths for arpegiator designs, I'm nearly certain it's the microcontroller/microprocessor that enabled all the but the simplest arpegiators.  I don't think you'll learn much by studying arpegiator schematics.  I think you'll learn a lot but studying how they behave and their many features, bells, and whistles.  You'd find that info in user manuals and especially by using them with your own hands.  From there, it's all software (not to trivialize that step!).

for a long long time i have wanted to be able to understand appregiators.
only recently have i started worrying that without understanding some programming, i will never have an appregiator.

so it was with great interest that i began looking at some old shematics for ideas last week...jupiters, junos.etc///till i realized that i understood almost none of what was going on
as it was working with a CPU


so...to make a long story short. WHAT is a realtively simple schematic to look at to TRY to understand synths with appregiators?





i suppose the problem is made worse due to the face that without seeing what is PROGRAMMED on the CPU....well maybe this is a useless exercise.

i do really dream of having an appregiators for my synths though.


thanks
