9.3 The Start, Stop, & Continue
buttons “do not react”
•
All tracks are muted, and no data is sent despite the
sequencer is running.
•
All steps are switched off, and no data is sent despite
the sequencer is running.
•
Due to the effects (Arpeggiator, Gater, Record-Step,
…) currently activated, the tracks do not send data
because they need incoming MIDI data to play.
•
Start & End step values are set to the same step
position, which if muted will send no data, even if
other steps are ON.
•
Individual parameters (Step, Gate, Delay, Midi-Event,
…) are set to extreme settings. These values, while
being sent correctly, may not be recognized by some
devices, may be ineffective, or out of range to bring
useful results.
•
Electric and lightning perturbation on the mains can
alter the contents of the non-volatile memory of the
Schaltwerk, leading to inconsistent data in the Pattern
presets. This can be especially annoying for Pattern 1,
as it is the default pattern at power-on. By running the
sequencer, this faulty data is processed and can lead to
erratic behavior. Try to correct the parameters in
editing mode before starting the sequencer. If you can
not correct the problem, the last solution is to save the
remaining patterns through SysEx, and then reinitialize
the Schaltwerk.
9.4 Changes made to a
Pattern/Song are not retained.
•
You forgot to save your changes into one of the 128
Pattern /16 Song memories after the editing, or you
have missed to confirm explicitly the save operation
with the OK button. As when selecting one of the 128
patterns/16 Songs, they can not be directly edited until
a copy is brought into the Pattern-Edit-Buffer. Changes
are only possible onto this copy and must be saved
back into a memory location again.
9.5 Problems to edit parameters in
the menus
•
If you enter an edit menu while several tracks are
selected, all parameters accessed will be set equal in all
these tracks with the value currently displayed, even if
you just take a look at the parameters without changing
them.
•
The editing of parameters with the buttons and the
rotary encoder is very slow, laborious and disjointed.
−
When editing values while the sequencer is running,
you should keep in mind that, as the inner computer
job priority for editing is lower than that of the play
functions, there could be some laziness in the reaction
time of the menus, especially with complex sequences
or fast tempo being at work.
•
The indication of the Step-LED/running cursor does
not match 100% to the actually expected position, or
particular interference effects can be seen.
−
Here too, is the software strategy at cause. The
display and LED’s have a lower priority than the
processing of higher priority tasks, such as the real
time processes: MIDI in and out, values fetching and
issuing, timing control, …that suffer no delay without
audible results.
9.6 Individual buttons react
differently
•
Due to the big quantity of buttons used in this single
device, there could be a slight disparity in production.
These small differences can lead to subtle variations
in the behavior of the buttons.
−
Provided that this effect is slight, it is perfectly normal
considering the goal of high production to keep the
cost down.
