Local Control Switch

The switch called LOCAL CONTROL on TPX2s/4s/6 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.

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 in section 3.

7. External MIDI Devices

This section gives some basic information about using external MIDI controllers and tone modules
with TPX2s/4s. Information on working with a sequencer will be made available in a separate
document.

Controllers

All MIDI controllers connected to MIDI IN will be compatible with TPX2s/4s, including keyboard
controllers, ribbon controllers, breath controllers, wind controllers, MIDI guitars, etc.
Standard Synthesizers and Samplers
Synthesizers and samplers connected to MIDI OUT should be MULTITIMBRAL. Check the MIDI
Implementation Chart of any unit you will be connecting. The following parameters must be there:
