SINGLE: Edit
Function?
This is where you set how the TX81Z will be controlled by incoming MIDI
messages. Answer YES to the “?” display and use the PARAMETER keys to
select the sixteen Function parameters.
Poly Mode (Poly/Mono) Poly Mode: In SINGLE mode, the TX81Z will play up to 8 notes simultane-
ously, and in PERFORMANCE mode, each instrument will play as many
notes as permitted in the “Max Notes” setting for that instrument (p.38).
Mono Mode: Only the most recent note you press will be sounded. This can be
desirable when playing solos. Also, Mono Mode gives you a choice of porta-
mento (see below). A Max Notes (p.38) setting of 1 is not quite the same as
Mono mode. In Mono, a note played before the previous one is released will
not re-trigger the envelope. ie. the decay will continue from the previous
note. However in Poly mode, each note starts its envelope from the be-
ginning even if the previous note has not been released. Thus, if you want to
have only one note sounding at a time, but want each note to re-trigger the
envelope, use Poly mode and set Max Notes (p.38) to 1.
Note
If you play a note in Mono Mode without releasing the previous note, and
then release the second note, the sound will “jump back” to the previous
note. In SINGLE mode, up to 8 of these previous notes will be remembered
(as long as you continue pressing them), and in PERFORMANCE mode, up
to 5 notes will be remembered.
P Bend Range (0-12) This determines the range (in semitones) of the pitch bend effect. When set to
12, the pitch bend wheel on your keyboard will have a maximum effect of one
octave up or down. When set to 0, the pitch bender will have no effect.
Full Time Portamento/
Fingered Portamento
There are two modes of Portamento (the “glide” between notes), but you have
a choice only in Mono Mode. If Poly Mode is selected, this will always be “Full
Time Portamento”. With Fingered Portamento, portamento is applied only if
you press a note before releasing the previous one. With Full Time Portamento,
portamento is applied between all notes. Full Time Portamento can be turned
on or off by a portamento footswitch connected to your keyboard, but Fingered
Portamento cannot be switched off. If you don’t want to have Portamento,
set the Portamento Time to 0 (see below). When power is turned on, porta-
mento will be on. (And when a Performance is selected, portamento will be on
for each instrument in the performance.) To turn portamento off, you will
need to send a Portamento Off message (Bn.41.00)
Portamento Time (0-99) This sets the speed of the “glide” effect between notes. When Portamento Time
is at 99, a three-octave glide will take about 30 seconds. When Portamento
Time is at 0, there will be no glide. If you don’t want a voice to have porta-
mento, set the Portamento Time to 0.
