PROGRAMMING
Programming is done while one of the STEP LEDs is ON (not Ready mode - BLINKING) and the sequencer is not
running. You can enter Program mode by pressing RESET a second time, or pausing a sequence with the RUN
button. Use the STEP LEFT and STEP RIGHT buttons to pick which step you want to program, then press the note
you want that step to play. The new note is automatically stored in memory.
STEP LEDs
The row of 16 LEDs along the top are referred to as STEP LEDs, and have the following states:
•
BLINK:
Ready Mode
- Starts on selected step. Can play keyboard live.
•
ON (Steady):
Program Mode - Any notes you push will get saved in the selected step.
SEQUENCER RANGE / OCTAVES
The 3650 covers 5 octaves, so you can use the OCTAVE UP and OCTAVE DOWN buttons to transpose the
keyboard / sequence up and down. The OCTAVE UP and OCTAVE DOWN LEDs indicate the current keyboard
octave. Note that Buchla synths use 1.2 volts per octave.
•
Down ON:
-2 Octaves (0V to <1.2V)
•
Down FLICKER: -1 Octave (1.2V to <2.4V)
•
Both OFF:
Middle Octave (2.4V to <3.6V)
•
Up FLICKER:
+1 Octave (3.6V to <4.8V)
•
Up ON:
+2 Octaves (4.8V to <6V)
REST, LOOP & ACC
In addition to standard notes, you can also program a
REST
,
LOOP
or
ACC
into a step:
•
REST: Replaces the selected note. A REST step holds the previous note and does not fire the gate.
•
LOOP: Replaces the selected note. A LOOP step sets the sequence back to step 1. You can use this to
create any length sequence you want. For example, if you only want steps 1-13 in your sequence, you
will make step 14 a LOOP step.
•
ACC:
In addition to a note, rest or loop, the handy and flexible ACC (accessory) output can be
programmed into any step. Use the ACC output to trigger other sequencers, envelopes, or anything else
your imagination comes up with. The ACC button toggles it on and off.
RESET / PROG Button
The RESET button has several additional functions. It is used in conjunction with some of the other buttons on
the sequencer to enable and disable various modes and is indicated by square brackets around the text.
ACC OUT
The ACC (ACCessory / ACCent) output can be programmed into each step. There are 3 on modes to choose
from:
•
On (Stays on for entire duration of step and does not drop before the next step)
•
On w/ Drop (Stays on for most of step, but drops briefly before the next step)
•
Gate Follow (Timing follows gate timing for the step)
When programming a step, each press of the ACC button cycles to the next mode. The ACC LED will flash to let
you know what mode you have set:
