Envelopes
The TEO-5 has two 5-stage DADSR envelope generators (delay, attack,
decay, sustain, release), using the voltage curves from the historic Ober-
heim OB-8 (these are also found as an option on the Oberheim OB-X8).
They are useful for creating modulation that varies over time according
to the shape of the envelope. Routing an envelope to Filter Cutoff, for
example, causes the lter to open or close according to the contour of the
envelope. Routing an envelope to Amplier causes the volume to change
according to the contour of the envelope.
Similarly, using one of the envelopes as an auxiliary envelope and rout-
ing it to a different destination in the mod matrix allows you to apply
modulation that changes according to the contour of the envelope.
There are many creative ways to use the Envelopes:
• Use the mod matrix to route Envelope 1 or 2 to one of the oscillators’
frequency parameter to create the classic “pitch blip” effect used in
many synth lead sounds.
• Use the mod matrix to route Envelope 1 or 2 to one or both of the oscil-
lators’ pulse width parameter to make their timbre evolve according to
envelope’s contour.
• Use the mod matrix to route Envelope 1 or 2 with a fast attack and
short decay to noise (level) to add a percussive attack to a sound.
(Noise level should be set to zero in the Mixer.)
