Programming a Tuning Table
Programming a tuning table means storing it in one of the 32 possible memory locations. Tables are
programmed using Tonal Plexus Editor (TPXE) software. Please see the software documentation for
information on creating and programming tuning tables.
NOTE:
When sending tuning tables to TPX6s/8s keyboards, first set all the faders
to zero (the leftmost position). This will help ensure that data is received for
every key of the tuning table, a known issue for these keyboards. If some keys
still do not get programmed, the table should be sent again.
Local Control Switch
The switch called LOCAL CONTROL on TPX6s/8s provides a way to disconnect MIDI traffic coming
from the keyboard. This setting should be used when you wish to control the synthesizer from an
external source such as a sequencer. When LOCAL CONTROL is set to OFF, the blue LED lights up
and the keyboard no longer generates MIDI data; however, incoming MIDI data is still sent to the
internal synthesizer. This function is unlike standard LOCAL OFF control, where MIDI data is still sent
from the keyboard. The reason for this is that MIDI channel control may possibly be in conflict if MIDI
data input and MIDI output are both allowed to directly control the internal synthesizer when
bypassing the internal dynamic channel allocation algorithm. MIDI output is however still sent to the
THRU output, so in a limited sense the function is as expected for a LOCAL OFF situation, with the
caveat that output can only be UNTUNED in this situation, and some functions become inactive in
this mode.
Octave Buttons
The octave buttons do not simply transpose MIDI Notes by octaves. Instead, they control which
tuning table registers are accessed by the MIDI Notes played. So, the word “octave” in this case
should be understood to mean a tuning table MIDI map octave as described above.
4. Polyphony
TPX6s/8s achieves microtonal polyphony through a MIDI channel assignment system, called a
dynamic channel allocation algorithm. Each retuned MIDI Note requires its own MIDI channel.
Therefore, polyphony is limited to 16 voices according to the present MIDI standard.
