Known bugs in Version 1.7:
1. Selecting a different song while a sequence is running can cause a system
crash.
2. Performing any of the following sequencer functions when there is very little
sequencer memory remaining can cause a system crash:
a. Saving or merging a track
b. Erasing a track
c. Recording a track
3. The system will occasionally lock up after loading data from MIDI. The data
transferred intact, but the ESQ-1 never returns from flashing PLEASE WAIT.
Turning the unit off and on again cures the problem.
4. The first time that MIDI data is loaded after powering up the unit, the unit
has a tendency to fail to load; the display will read TARGET SYSTEM NOT
RESPONDING, even though all connections are correct. The data load will be
successful if tried again.
5. Due to "jitter" on the part of the Data Entry Slider, parameters on
Programming pages and Tempo on Sequence pages will sometimes jump to the present
value of the slider.
Known bugs in Version 2.0:
1. It is possible to set the pitch bend range outside the legal limit (49 to
63). It is necessary to re-initialize the unit to reset the pitch bend to the
proper range of 0 to 12.
2. The sequencer sometimes fails to accurately record SUSTAIN pedal information.
3. The sequencer will sometimes play back key down events with velocity of 0 if
the key had been recorded with a low velocity value.
4. In MIDI MONO mode, the ESQ-1 may not properly receive program changes on all
channels.
5. When syncing to tape, the sequencer will sometimes play the first note of the
sequence as soon as the user presses play, putting the rest of the sequence out
of sync.
Version 2.2 fixes/adds the following:
1. A parameter was added to allow the CV Pedal to be used as a volume pedal
as well as a MOD Pedal.
2. Allowed data dumps to disk drives capable of accepting generic system
exclusive messages.
3. Allowed compatibility with MIDI Guitar controller.
4. Ability to output a tape sync clock when syncing to MIDI clocks as well as
when syncing to tape.
Version 2.3 fixes/adds the following:
1. 40 internal patches are loaded from the OS rom's after initialization.
2. Fixed a bug which caused erratic operation when using the LOCATE function by
more than 16 bars.
Version 3.0 fixes/adds the following:
1. Added sequence editing features which allows addition and deletion of
variable bars at any boundary within a sequence.
2. Ability to rename songs by pressing the soft button above the song name on
the SONG EDIT page.
3. Allowed startup screen to automatically switch to last selected internal
page.
4. VELOCITY parameter renamed to TOUCH.
Version 3.0 adds the following:
1. Ability to remain in SONG mode even after unit was turned off.
Version 3.4 fixes the following:
1. Corrected a sequencer problem which prevented the ESQ-1 from recording correctly with synchronized (SYNC=MIDI CLOCK) with units which send clocks continuously.
Version 3.5 includes the following:
1. Corrected waveform pointer in EPNO2 waveform.
2. Restored the values of the TOUCH parameters to their original and correct
order, HARD, MEDIUM, SOFT.
