The Mode button enables you to select one of three modes: Env (standard envelope mode),
Run, and Loop.
• In Standard Envelope mode, the envelope will cycle once through its stages and
stop at the end of the Fall stage.
• In Run mode, the envelope (now an LFO) is free running. It resets when the
MicroFreak receives a MIDI start command.
• In Loop mode, the envelope (now an LFO) resets when a trigger is detected from
either the keyboard, the sequencer or the arpeggiator. It syncs to the external
trigger.
In Run and Loop modes the envelope will retrigger itself when the end of the Fall time is
reached.
In standard mode, the envelope starts when it receives a gate from the keyboard or an
external source. The Rise stage is the attack stage. The Sustain stage will remain high as
long you press a key on the keyboard. When you let go of the key, the gate ends, and the
envelope will continue to the Fall stage.
In Run and Loop modes, the Rise stage is the attack stage and Hold will keep the level of the
Cycling Envelope high for the duration you've set with the Hold knob. When the Hold period
ends the envelope will continue to the Fall stage.
Note: To get a feel for the effect of changes you make to the stages of the envelope, connect
it to the pitch of the Digital Oscillator.
• Move the selection point on the Matrix to the CycEnv->Pitch point.
• Press the encoder and set the modulation level to about 20.
• On the Cycling Envelope Generator set Rise to about 200 ms, hold to 0, fall to
0ms and amount to 50%.
You'll hear the pitch go up and then slowly fall to its starting point. This setup also illustrates
the effect of the Amount knob. Decrease Amount and the pitch rise will less noticeable.
Tip: Try modulating the pitch of the Digital Oscillator with the Cycling Envelope in loop mode.
If you select very low values for Rise, Fall and Hold, the Cycling Envelope will cycle at a very
high rate and will function as a complex LFO. By changing the Rise, Fall and Hold time you
can change the waveshape of this "LFO".
In Run mode the pitch of the oscillator will change continuously.
To hear the effect in Loop mode, the Cycling Envelope must be triggered externally by the
keyboard or the Arpeggiator/Sequencer. To hear its effect activate the Arpeggiator, set the
speed of the Arpeggiator to about 55 bpm, and press a chord. You'll hear how the Cycling
Envelope retriggers every time the Arpeggiator moves to the next step.
