----- Note HOLD ------
You can instruct the Echotron to HOLD the next note played (see the
Parameter Menu below). When a note is on HOLD it will not decrease in
volume as it echoes, and it will not be overwritten by incoming notes
when the carousel is full. This is a very useful feature for setting
up a constant bass pulse and jamming over it. Better yet, if a trope
is active when you hold the note, then you can set up a whole bass
line or texture to be played over. And you can hold more than one
note :)
----- SAMPLE & HOLD ------
You can globally freeze whatever sound loop the Echotron is producing
by enabling SAMPLE & HOLD (toggled via the Parameter Menu, see below).
Then you can jam over it freely.
----- ISO-TEMPO -------
This feature allows the Echotron to maintain a constant tempo,
regardless of the number of notes in the carousel. So if there are 4
notes currently echoing in the carousel and ISO-TEMPO is on, then the
delay time will be 1/4 of what it would be if there were only 1 note
in the carousel. The "Telepromt" and "Frara Jaqua" presets use ISO-
TEMPO. You can toggle ISO_TEMPO via the Parameter Menu (see below).
----- ENVELOPE ------
A master envelope dynamically controls the amplitude of the notes
produced by the Echotron. This envelope is a traditional ADSR
(Attack/Decay/Sustain/Release) but with a twist: a
Sustain Tsime
parameter is added. When the envelope for an echoing note reaches the
sustain stage it will automatically release after the
amount of time specified by the sustain time parameter. The various
stages of the master envelope can be controlled via the pots (see
below).
----- PULSE WIDTH ------
The notes produced by the Echotron use square wave oscillators. The
PULSE WIDTH of these oscillators can be modified via a pot (see
below). The pulse width controls the ratio between the positive and
negative edges of the square wave and can radically alter the timbre
of the tones.
