As long as the D-1 (insert) gate is held high, the step parameters of
the just inserted step will follow any voltage changes according to the table
above. The step parameters are locked and will no longer change when the
D-1 (insert) gate goes low.

Since steps are added at the edit cursor, you can have the sequencer
playing (and looping) the section as you add/remove steps.
4.3 Alter mode
This mode is similar to the REAL-TIME mode in that steps under the play
cursor are aected and recording happens in real-time. However, no steps
are inserted in the armed tracks. Instead, step parameters are overwritten
with new values (derived from the input voltages) just before the play cursor
encounters the step and then plays it. Of course, if you are looping a single
step then the currently playing step and the next step about to be played
are the same step. In this case, voltage changes are reected immediately.
Except for the D-1/D-2 inputs which are not used, the jack mapping
and relationship between voltages and step parameters is the same as in the
STEP recording mode:

The typical useage scenario for the ALTER record mode is to lay down
new automation or melody on an existing sequence of steps. However, there
are many unusual and interesting possibilities that can lead to complex re-
sults when using non-synced LFOs or even feedback from the ER-101 itself.
A particularly useful setup is to synchronize a traditional analog step se-
quencer with the ER-101 but have all of the analog step sequencer's outputs
go through the ER-102 in ALTER record mode. If the ER-101 is looping a
