Lfo 1-3 Modulation Oscillators - Quasimidi POLYMORPH Operating Instructions Manual

Basics
<ATTACK> RISE TIME
This parameter determines the amount of time it takes for the envelope level to travel from the
initial to the peak level (when the key is struck). In the case of the VCA-EG this means, how much
time has passed until the highest volume is reached. Percussive instruments need a very short
attack time and string sounds are usually quite long. For the filters, it controls how fast the filter
opens (or closes depending on the <ENV-MOD> setting.)
<DECAY> DECAY TIME
This parameter determines how fast the envelope falls from the peak to the sustain-level after
passing through the attack phase.
<SUSTAIN> HOLD LEVEL
This parameter is not an indication of time. Rather it is a level that is held after the decay time until
the key on the keyboard is released. For the VCA-EG, if the sustain level is regulated to 0, the
POLYMORPH sound would end after the decay phase regardless of how long the key is held. If the
sustain level is higher than 0, the corresponding tone will be held until the key is released and the
release time is finished.
<RELEASE> RELEASE TIME
This is the length of time that the sound can be heard after releasing a key. You can adjust the
release time between stopping abruptly or slowly fading away, or in the case of the filters, how long
before the filter closes after the key is released.
