F-em User Guide
4.3 Master Section
Here, you can make global settings for playback.
•
Playing
: Shows the number of the current
played voices. Keep in mind, that every of the
4 Layers plays its own voice, so the total
number of played voices is 4 when all four
Layers are active and you play a single note
(and Unison is set to 1).
•
Voices
: Determines the maximum number of
voices that F-em produces (up to 256 voices, default is 40).
Decreasing the number of voices improves efficiency and therefore
reduces load on CPU. If voice count is set too low, then “voice
stealing” can occur with the possibility of audible artifacts.
•
Master Tune
: 440.00 Hz is widely used as concert pitch in the United
Kingdom and the United States. In continental Europe, the frequency
of the note A commonly varies between 440 Hz and 444 Hz. In the
period instrument movement, a consensus has arisen around a
modern baroque pitch of 415 Hz (A
b
of A 440), baroque for some
special church music (Chorton pitch) at 466 Hz (A# of A 440), and
classical pitch at 430 Hz.
•
External
: When enabled, the arpeggiator(s) and all clock-based
parameters (LFOs, Envelopes, Clocked Delays etc.) are synchronized
to the tempo of your host application. If disabled, you can specify a
desired tempo in BPM (see Tempo option below).
•
Tempo
: Adjusts the tempo when External is disabled. This can be
useful if you prefer a rhythmic pattern to be half or double time. By
double click on
Tempo
, it will be set to default 120 BPM.
4.4 Arpeggiator Master Section
The arpeggiator is used to sequence rhythmic
patches. Each of the 4 layers can have its own
arpeggiator settings, but this section controls the
global arpeggiator settings for all layer
arpeggiators simultaneously.
•
On
: Toggles the operation state for all arpeggiators to on or off.
•
Latch
: Enables the arpeggiators to remember the last set of keys
played on the keyboard. When enabled, the arpeggiator sequences
will continue to play even after the keys have been released. Once all
keys are released, the next chord to be played will clear the latch
memory and only the newly played chord will be arpeggiated. To
stop the arpeggiators with Latch enabled, press the “On” button.

Please keep in mind that the chosen number of unison voices will
respectively add more CPU usage.
