Clock Assignment
Clock assignments can be programmed using CVs and pulses. The
CV input next to the
“assign” knob selects the ring, and a pulse at the pulse input next to the “assign” button
starts the assignment.
Note that the assignment is not fixed when the button is pressed (or
pulse received), so if you turn the knob or change the CV before cell 1 is reached on the ring
currently assigned to the clock, a different ring will be assigned than the one that was originally
selected.
Synchronization
Press the “sync” button to change the clock synchronization method.
Sync
mode “on 1” means that cell 1 of all active rings will happen at the same time . The
master clock will run at the indicated BPM, and clocks two and three will drive their assigned rings
at whatever rate is necessary to get the ring to cell 1 on time.
Sync mode
“on cycl” means that all cells will advance at the same rate.
If neither sync LED is illuminated, the clocks are not synced. In this mode you can press
and hold the “assign / ∆t” button for a clock to enable its time scaling mode
. In this mode,
the green LED is illuminated and the clock knob will scale the master BPM, from .5x – 3x, as does
the knob’s associated CV input.
Pressing the “reset” button will force all active rings to resync at cell 1 .
MIDI CLOCK
The 252e supports MIDI clock sync receive and transmit. This is sent over the internal bus. To
enable these modes, press and hold the “MASTER BPM” encoder. The display will change to
“
oFF
”. Turning the encoder selects “
S rc
” for “sync receive”, and “
S tr
” for “sync transmit”.
Receiving: You can use external MIDI gear to send messages to the 252e through a 225e or
through the FirmwareCard in USB MIDI I/O mode (225m) See the USB Firmware Card
description at the beginning of this manual.
To transmit to MIDI Clock messages from the 252e to USB-MIDI, you can also use the Card.
Recalling and Saving Presets without a preset manager
Combining the 252e with a preset manager is the recommended way to name, save and develop
your sequences and rhythms. It is not uncommon to develop a set of patterns and make variations
that can be recalled with a preset change.
But for users who have a small system with no preset manager, presets can be called up
with MIDI preset commands that are sent over the internal MIDI bus using the
FirmwareCard’s USB MIDI I/O feature (called 225m) or the 225h. Patches are saved into
that preset location by pressing the remote enable button. The LED will then go out.
