> Depending on the LFO’s waveform, the effect will sound like a faint vibrato or a large wobble (sine or triangle), a trill (square), a series of random pitches (sample and hold), to name a few.

> Amplitude modulation:
>
> The LFO, internal to MD, will affect all operators independantly: Rate will be common, but modulation depth can be set differently on each operator.
>
> If the operator is a carrier, the LFO will affect the general volume of the preset. A sine wave LFO applied to a carrier operator will result in some kind of tremolo effect.
>
> If the operator is a modulator, the LFO will affect the harmonic content of the preset. A sine wave LFO applied to a modulator operator can, in most cases, be compared to an automatic Wah-Wah effect. A sample and hold LFO applied to a modulator operator will result into a series of notes with random brightness.

###### Pitchbend
The pitch of the note can be raised or lowered using the Pitch Bend control (Usually a dedicated wheel or joysitck on a master keyboard). The range can be set up to 1octave on both directions (up/down). *Range* setting defines the highest possible variation: from one semitone to a full octave.

### Load/Save
MD can save settings for effects and sound separately from the voice/bank parameters. Furthermore it is even possible to call up finished combinations of these three variants.
#### Performance
A performance is a combination of an effect setup, voice setup and the selected voices themselves (see below for descriptions of effect setup and voice setup).
Loading and/or saving a performance makes it possible to call up or save a complete setup ready to play for live operation.
---
> __Hint on Performance:__
> It is possible to call up a performance directly via the first used MIDI channel using MIDI Bank Change/MIDI Program Change.

#### Voice config
Voice configurations store all data beyond the sound data itself that is necessary for playing. Voice-Configs should not be confused with the voice data (inside a bank) that describes the sound. All data that are not stored in the voice data are stored there:
* MIDI channel
* MIDI lowest note
* MIDI highest note
* Tranpose
* Tune
* Internal level
* Panorama
* Polyphony
* Velocity level
* Engine Type
* Mono/Poly
* Note refresh mode
* Pitchbend:
* Range
* Step
* Modulation wheel
* Range
* Assign
* Mode
* Foot controller
* Range
* Assign
* Mode
* Breath Controller
* Range
* Assign
* Mode
* Portamento
* Mode
* Glissando
* Time
* Operator status
#### Effects
Effect configurations save all settings for the effects and are independent of voice configurations or the voices themselves. The following parameters are stored:
* Filter cutoff
* Filter resonance
* Chorus
* Frequency
* Waveform
* Depth
* Level
* Delay
* Time
* Feedback
* Level
* Reverb
* Send
* Roomsize
* Damping
* Level
* Equalizer
* Bass
* Treble
#### MIDI
The following menu items allow data exchange via MIDI-SYSEX with editors/libraries or other (compatible) synths.
##### MIDI Recv Bank
A bank consists of 32 voices. These can be sent in a block to MD. Before you can send them, you have to select a bank slot and maybe want to edit the name of the bank on MD's side.
5. Now you can choose to edit the name of the new bank. The blinking cursor is located on the first character (on the left) and can be moved with the preset encoder in this example to the position of character the "4").
10. Now can go to step 5 and edit the other characters like the first one, or you can go one position after the last character to leave the edit screen. An OK prompt will apear on the right.
