Sockets
Trigger In
A positive gate or trigger voltage in here will activate the ADSR sequencer.
+ EG Out
A full level positive envelope signal from this socket. Level pot has no effect.
+/- EG Out
The EG signal is positive. By pulling out the EG knob, the signal is inverted (negative).
Controls
Attack
After receiving a Gate signal, this sets the time is takes the envelope to reach full level.
Decay
After reaching full level, this sets the time it takes the envelope to decrease to the Sustain
level.
Sustain
The sets the Sustain level. The envelope signal will remain at the Sustain level
(after
decreasing from the maximum level) as long as there is a Gate signal present at the
Trigger in socket (i.e. as long as a key is held down).
Release
After the key is released (the Gate signal no longer present), this sets the time it takes for
the envelope signal to decrease to zero.
Special EMS-Style Repeat Function
The EG01 has an EMS-style repeat function which is easy to use and adds powerful modulation capabilities.
When the sustain level is set to zero the repeat function will be active. The en ve lope will repeat (re-trigger itself) so
as soon as the envelope finishes its cycle, it starts all over gain. In this mode the EG becomes an LFO or Oscillator.
The speed is set by the Attack and Decay time. (The Release control will have no effect). By setting very short times
an audio signal will be present!
Whether the repeat is short giving high frequencies (audio signals) or slow (like an LFO), by varying the Attack or
Decay times you are changing the wave shape of the output. Anything from Saw to Triangle to Reverse Saw wave
froms can be created.
The unique way in which the EG01 repeat works is that it will only repeat as long as the Gate voltage is at the Trigger
input (i.e. the key is held down/sustained). This is a great bonus compared to other repeating envelopes in that rather
than repeating indefinately, it will only repeat as long as you want it to (by controlling the length of the Gate signal). One
application of this is by setting the repeat function to create an audio signal. The output will only produce audio when a
Gate signal is present. This gives you a gated audio signal - effectively an Oscillator through a VCA.
