* The output level of each operator varies according to the
velocity at the time of reception. How much it varies depends
on the velocity sensitivity set by the parameters (data) of
each voice. Also, with a voice whose attack rate velocity
sensitivity is set, the attack rate varies as well.
* The note range of this unit is from D # -1 to D7, it produces
D7 at the highest and D # -1 at the lowest even when a higher
note information or lower note information than the range
is received. For example, when D# -7 to D8 information is
transmitted, D# -6 to D7 tones are produced.
* When the MONO ON/POLY ON mode is switched, the sound
being generated is stopped and sostenuto is turned OFF.

© Active sensing (FEH)
* Once this code is received, sensing is started. If no status
or data is received within 300msec, the MIDI receive buffer
is cleared and the sound being generated is stopped.

© Real time clock (F8H)
* This clock for system timing and is sent at a rate of 24 clicks
per quarter note.
© Start (FAH)
© Continue (FBH)
® Stop (FCH)
* Counting is started by the start or continue signal and stop¬
ped by the stop signal.
* The control No. 1 receives a signal when the "WHEEL" con¬
troller is specified for the pitch modulation controller.
Likewise, No.2 and No.4 receive a signal when "BREATH"
and "FOOT" controllers are specified, respectively.
