Introduction
This is the user manual for “Enkl - Monophonic Synthesizer”, developed
by Klevgränd produktion. The synthesizer comes in two versions – an
iPad app and a Desktop plugin (AU & VST).
Get the iOS version at the App Store!

The name Enkl comes from the Swedish word “Enkel”, which translates
to “Simple” or “Easy”. With that name, we’re trying to say that the app is
easy to use. A stroke of geniusmentness!
Enkl’s sound is generated by two oscillators with one LFO each. These
oscillators can be added, subtracted or multiplied together, and
optionally processed though a filter.
In addition to the above, there is a simple built-in arpeggiator, a delay
and a three-band EQ.

1. Oscillator(s) →
2. are modulated (Amplitude or frequency
modulation) →
3. with an LFO + ADSR.
4. Both signals are summed (added, subtracted or
multiplied) →
5. and sent to the Low Cut filter with resonance →
6. and also passes the High Cut filter with
controllable attack time.
7. The signal goes through an ADSR →
8. and runs through an EQ and Delay (if set to on)
9. Finally it passes the output gain and we’re done!
2. Oscillators
1. Waveform type: There are four types of waveforms: Triangle,
Sawtooth, Square and noise
2. Filter switch: Click to enable / disable filter
3. Phase offset: Drag the slider to change the starting offset of the
waveform between 0 and 360 degrees
4. Base pitch: The topslider changes the note’s pitch in octave
increments,, the second slider in semitones, and the third in cents for
fine tuning
5. Gain: Increase the volume of the oscillator signal
3. LFOs
6. LFO mod type: Sets how the LFO should modulate the oscillator
above. AM creates amplitude modulation (multiplying the two signals),
while FM alters the pitch (frequency) of the oscillator
7. LFO Waveform type: From left to right: !
Sine, Triangle, Sawtooth, Square, Noise
8. ADSR envelope: Drag the sliders to alter attack, decay, sustain and
release for this LFO
9. LFO Gain: Sets the overall level of the LFO. (Note: If the LFO is set to
AM, see 6, and gain is set to 0, the final output will be silence)
10. LFO Frequency: Ranges from 0.1 Hz (min) to 20 Hz (max)."

4. Global
1. How the oscillators output should be combined. Add: adds the
oscillators together, Sub: subtracts one oscillators from the other,
Mult: multiplies the oscillators
2. Glide speed: If legato mode is selected (3), this knob sets how long
time it takes for the pitch transition between two notes
3. Legato: If MIDI input is legato, no ADSRs will get retriggered when a
new note is trigged
4. Arpeggio switch: If multiple notes are held, these will be played after
one after the other as an arpeggio
5. Arpeggio speed: how fast the arpeggio should be played
6. Main ADSR: Drag the sliders to alter attack, decay, sustain and
release for the output volume
7. Master volume: Controls the output volume
5. Filter
8. Low Cut: Sets the low cutoff frequency for oscillators with filter
enabled. This parameter is also controllable via MIDI (CC 22)
9. High Cut: Sets the high cutoff frequency for oscillators with filter
enabled. This parameter is also controllable via MIDI (CC 23)
10. Resonance: alters the resonance of the low-cut filter. This parameter
is also controllable via MIDI (CC 24)
11. Filter attack: Sets the time it will take the high-cut filter to reach its
destination value (depending on which note is played)"

6. Effects
Delay
Activates a ping-pong delay that jumps between left/right channels.
1. Delay on/off switch
2. Delay time
3. Feedback
4. Stereo spread amount
5. Mix between dry (min) and wet (max) signal
EQ
The three-band EQ is controlled by dragging up/down to alter gain levels
and sideways (near the vertical lines) to alter crossover frequencies.
6. EQ on/off switch
7. User interface. Drag and move to alter values
8. Additional settings
8. Range (in semitones) of the maximum pitchbend
9. How fast the vibrato should oscillate
10. Max vibrato that should be generated when !
vibrato messages are sent from MIDI."
