Aside: How the manual and
drawbars are related
• Drawbars
At each push of a key all nine harmonics of this particular key are
generated. The drawbars simply adjust the levels among them. Thus
you can change the timbre while keys are pressed.
Note: Located under every single key of an original tone wheel organ were
nine contacts, which were all closed at the same time by pressing the key.
A bus system then regulated the volume for each contact via each of the
nine drawbars.
With your NUMA Organ you can play three diff erent timbres at the
same time. To do this you may connect another MIDI keyboard and
a MIDI pedal board to the NUMA Organ (refer to page 17), or split
the manual of the NUMA Organ into two zones (refer to Split on
page 13).
Use the buttons Upper, Lower and Pedal to select the assign of the
drawbars. The active button will light up.
Upper: The drawbars form the timbre of the whole NUMA Organ
manual or, in Split mode, for the upper manual.
Lower: The drawbars form the timbre of an optional additional
keyboard or, in Split mode, for the lower manual.
Pedal:The drawbars form the timbre of an optional additional bass
pedal board or, in Split mode, for the lower manual, if Pedal to
Lower is activated.
Special Drawbar setting for Pedal:
To adjust the timbre for Pedal you can only use the drawbars
1
and
2
. Drawbar
1
represents the 16‘ harmonic, while
drawbar
2
now adjusts the 8‘ harmonic!
For Upper and Lower all nine drawbars are accessible as
previously described.
