FM+
FM+ is 21st century FM synthesis. It imple-
ments world class frequency modulation
algorithms that address the complexity prob-
lem normally associated with FM.
All three FM+ machines are based around a
number of custom made FM blocks. The
machines have then been handcrafted, each
with its own personality.
It is not necessary to understand the detailed
machine descriptions of the FM+ machines.
Good results should be possible to attain
only by trying out the effects of the parame-
ters and get a good “feeling” for them.
All the FM+ machines use a special com-
bined amplitude and envelop controller. This
is visualised by the figure below:
FM+STATIC “FM+STAT”
FM+STATIC is the most versatile of the FM+
machines, and the best bet for successful
FM synthesis.
1FRQ - Modulator 1 Listed Frequency
1FIN - Modulator 1 Frequency Fine Tune
1ENV - Modulator 1 Volume & Envelope
1FB - Modulator 1 Feedback
2FRQ - Modulator 2 Listed Frequency
2VOL - Modulator 2 Volume & Feedback
TONE - Harmonics Control
Modulator 1 offers both fine and coarse fre-
quency tuning. The 1FRQ parameter con-
trols the coarse frequency from a choice of
Listed Frequencies, selected for yielding
good results for FM synthesis.
The 1FIN parameter controls the fine fre-
quency tuning for precise adjustments.
The 1FB parameter controls the Modulator 1
feedback.
The 1ENV parameter controls the final out-
put volume of the first FM block, as
described by the FM+ Envelope figure.
