36 MOTIF Basic Structure
The maximum sonic polyphony is 62 for AWM2, plus the polyphony of the Plug-in Board (if installed). The actual
note polyphony will vary depending on the type of tone generator unit used, the number of Elements in the Voice,
and the note polyphony of the Plug-in Board.
In the case of AWM2 Voices, the polyphony ﬁgure of 63 is divided by the number of Elements in the Voice.
Part structure of the Tone Generator block
The MOTIF plays its sounds (with the Tone Generator block) in response to MIDI data, received from the Controller
block or Sequencer block.
MIDI data is assigned to one of sixteen channels, and the MOTIF is capable of simultaneously playing sixteen
separate parts, via the sixteen MIDI channels. However, we can overcome the sixteen-channel limit by using
separate MIDI “ports,” each supporting sixteen channels. The multiple sound sources of the MOTIF (internal tone
generator and Plug-in Boards) take advantage of the three MIDI ports included on the instrument.
As shown in the above illustration, up to 48 parts can be used in the modes (excepting the Voice mode). However,
the number of parts that are actually used is a maximum of 34 in the Song and Pattern modes, as we’ll see later in
nSee page 30 for details about the modes.
nThe USB cable supports up to eight separate MIDI ports. The MOTIF’s Tone Generator block supports three separate ports as
illustrated above, and the MOTIF’s MIDI Thru function supports eight separate MIDI ports.
nThe MIDI cable and IEEE cable (when the mLAN8E has been installed) cannot handle MIDI port data.
These parts are used in
modes other than the
Tone Generator block
