Subject: TB-303 pattern lengths

In the Analogue Heaven mailing list, Bror Gundersen asked how to set
the pattern length of a TB-303.
Patterns can be from 1 to 16 steps long. After you clear the
pattern, it is 16 steps long.
You can set the length as you wish by holding the FUNCTION button (to
the right of the RUN/STOP button) down, and pressing the "STEP" button
(the one numbered "9") as many times as you want steps.
This will clear the timing information in the pattern, but not the
pitches or the accents and slides which you have programmed with those
pitches. You will have to re-enter the notes, continuations and rests
after changing the number of steps.
Curiously the pitch, accent and slide memory of each pattern seems to
be 48 steps long - but only the first 16 steps can have notes assigned
to them. I have not got to the bottom of this. I don't know how to
make them musically useable.
There is a related function, which controls the division of clocks
into steps. Roland DIN Sync is 24 pulses per quarter note - or 6 per
sixteenth note. There is a "triplet" mode in the TB-303, which makes
that pattern divide the clocks differently to play three steps in a
quarter note rather than four. Thus it takes 8 clock pulses to make a
step.
To set a pattern to this mode, hold the FUNCTION button and press the
Triplet button (with the 3 1/8 note symbols, and numbered "0"). This
sets the pre-scale for that pattern, and normally there is no way of
setting it back without clearing the pattern.
Here are some additional details of the triplet pre-scale function. If
the number of steps in the pattern when you set it was greater than
12, then the number of steps is changed to 12. Subsequently, you can
set the step number to anything between 1 and 15. A 15 step pattern
in triplet pre-scale mode takes 5 quarter notes to play.
If you set the number of steps to 16, then this turns off the triplet
pre-scale mode. This can be used as a way of reverting to ordinary
pre-scale mode without clearing the pattern. On the other hand,
clearing the pattern does not get rid of the notes (or accents or
slides) so it is probably easier to clear the pattern anyway.
Another related function is the ability to chain patterns together in
manual play or in track write mode. 2, 3 or 4 patterns can be chained
together simply by pressing simultaneously the lowest and highest
pattern switches - with the following restrictions:
12
123
1234
23
234
34
56
567
5678
67
678
78
Since each pattern can have any length from 1 to 16, and have a
normal pre-scale (4 steps per quarter note) or the triplet pre-scale
(3 steps per quarter note), now that you have read all this, there is
no excuse for being restricted to straight four-on-the-floor TB-303
patterns any more.
Its time for the Waltz and various new rhythms which are more
challenging to dance to.

Net zoals zijn vriend de MC-202 die nog erger is..
