SQ-80 — Musician's Manual
3. L3 - LEVEL3
The LEVEL that the Envelope will reach at the end of TIME 3. This is the Sustain Level. The
Envelope will remain at this level until the key is released. After the Key is released, the Envelope
will return to Zero.
Range:
-63 To +63.
4. LV — Velocity Level Control.
This parameter makes all three Levels, LEVEL 1. LEVEL 2 and LEVEL 3, respond to Keyboard
Velocity, or how hard you strike the key. When the value of [LV] is raised, a softer keystrike
will decrease all three Levels. The greater the value, the more the Levels will decrease as you
play softer. Thus the Levels set by LEVEL 1, LEVEL 2 and LEVEL 3 define the maximum
Levels, and parameter [LV] subtracts from those Levels.
• Values of LV between L and 63L cause the envelope levels to be affected by velocity in
a linear fashion;
• Values of LV between 00X and 63X cause the effect of velocity to be exponential — little
effect until maximum velocity is reached. The direction of the modulation is the same — only the
curve is different. (See the diagram in the previous section which illustrates the difference
between linear and exponential effects of LV.)
Range:
L To 63L for Linear response, 00X To 63X for Exponential response.
5. T1V — Velocity Attack Control.
This control makes TIME 1 respond to Keyboard Velocity. Raising its value will cause a
decrease in the value of TIME 1 as a key is struck harder, shortening the Attack Time. The greater
the value, the faster LEVEL 1 will be reached with a hard keystrike. (This Parameter will have
no effect if TIME 1 = 0.)
Range:
00 To 63.
6. T1 - TIME 1
The amount of Time between when the key is struck and when the Envelope reaches LEVEL 1.
In most applications this is the Attack Time. The higher the value the longer the TIME. Range:
00 To 63.
7. T2 - TIME 2
The Time it takes the Envelope to go from LEVEL 1 to LEVEL 2. In most applications this is
the first of two Decay stages.
Range: 00 To 63.
8. T3 - TIME 3
The Time it takes the Envelope to go from LEVEL 2 to LEVEL 3. In most applications this is a
second Decay stage. At the end of TIME 3, the Envelope will remain at LEVEL 3 until the key is
released.
Range:
00 To 63.
9. T4 - TIME 4
Release Time, or Release plus Second Release (Simulated Reverb). For values of 00 to 63,
T4 defines the amount of Time it will take the Envelope to return to Zero from LEVEL 3 (or from
whatever it currently is, if LEVEL 3 has not yet been reached) after the key is released.
