Daisy chain method
You can daisy chain any 1 volt per
octave analogue from the cv out of the 303 and if you have retrofit cv and gate
then daisy chain 303's using pattern or track as the master and the retro as
the slave. Each machine plays the same notes (unless tuned to a different key)
but the CV cannot PASS ON ACCENT. So the accent cof slide of the slave can be
controlled via midi being kept in time via sync24 on the master.
Key method
If you tune each 303 to a
different note of a key e.g. CMaj E C G then chords can be played
If you have a midi analogue use
303 as master retro as slave then at the same time as the pattern plays on the
master use cv aux gates to control accent slide and cut off frequency for
random variation of the pattern or track playing. The cof control can be used
as a volume control if you choose a variable controller e.g. volume or data
slider see ctr list.

When syncing a track on the 303
if you press the function bar (below pitch mode) this will tell
You which bar of the track is
now playing. Also if in track play you press the pitch mode button this tells
you the pitch of the bar now playing, if you have made a mistake in programming
a pitch or the order of the patterns then go to track write and hold bar
function whilst pressing the combination of digits to reach the defective bar
and correct this or these bars and then ds to the end of the track as normal.
To increase the play time of a
single track install a back in the track this way you can press this any time
and either jump forward to this point or jump back and cycle round eg if you
have 200 measures and a back then 56 measures to the end you can play 255
measures then jump back and press ds to continue looping 56 measures etc. (not
much use except for track 7 where there is only la few measures to play with so
for added variation loop half way through).
Synchronization is the most common
form of hooking up the 303 to smpte/Midi clock sequencer tempo. The internal
tempo of the 303 is a bit variable so using the sync ensures better timing and
also provides sync divides for extra variation.
Sync24 (24 frames per clock
bar) comes from film production and uses HIFI180 degree 5 pin DIN not midi
cables.
Basic use is just clock on
clock off and continue. You can start patterns or tracks using the sync but
when re starting patterns the pitch returns to C so it’s probably best to use a
track (1 to 7)
If you are using a pattern
group (choice of 16) then try pitching up whilst using the sync.
You can also chain up to 4
patterns to run in succession e.g. 1 a to 4a I 5a to 8a I 1 b to
4b I 5b to 8b remember to keep these patterns in key and the same amount
of steps 16 in each for 4/4. If you don’t then the timing will drift
with the other instruments running from midi time code.
Sync divides can be used if you
have a sync II clock box this clocks the sync out at a division of 24 frames
e.g.
Using pgm to control the
division on a midi channel e.g. channel 8 for sync II clock
