Hi!

This weekend I run into something that could easily become
my favorite duophonic playing style. I was playing around with
my Analogue Shift Register, but what I will describe now
is also possible with a single Sample & Hold.

So far, I used high note priority for one, low note priority for
the other VCO, mostly playing bass notes with the left hand
and soloing with the right hand. The drawback is that either
note jumps to the other hand when You release the key.

Now I tried this: I switched my Kenton Pro-2 to *last* note
priority ("ne") and used one CV only. The CV directly
controlled VCO1 (the one for soloing), and was also
routed over the S&H to VCO2. The S&H is clocked
by the Keyboard - by the Gate signal. (Important note:
there has to be a short trigger pulse; the S&H must *not*
be open during the whole gate time!)
Now the playing technique is like this:
lifting all fingers from the keyboard and then striking a note
will *sample* the CV on this note. This note will be stored,
and I can play solos with the second oscillator. There is no
more need to hold the key of the stored note, as long as
I play the solo line legato.
And it is real fun to plug this 2nd VCO into the same highly
resonant filter which I control from the sequencer for these
percussion sounds. Got a pumping Schulze-like bass that
can be transposed every time I lift all my fingers. And nobody
forces me to sustain the *lowest* note - it's always the *first* note
that is sampled, while the "solo" VCO1 takes the last one.

Well, the context for all this was a slight change in my ASR module.
I replaced the flipflop for the 1st stage by a monoflop. I did it last
night and finished at 11:30. Then I had an exciting half hour improvising
(I always have my musically most creative phases when I discover
a new technical feature 8->) and I really felt like taking off.
At 12:00, when I was quite exhausted, my loving wife came in and
led me blindfolded to a table with my birthday presents.
The end of a perfect day!
