CHERRY AUDIO Surrealistic MG-1 Plus Manual de usuario

Cherry Audio Surrealistic MG-1 Plus User Guide - 1
The Surrealistic MG-1 Plus is a loving recreation of an oddball analog synth
from '70s/'80s consumer electronics giant, Radio Shack. The MG-1 was a
great sounding little synth with a few dumb limitations, all of which have
been addressed with Cherry Audio's Surrealistic MG-1 Plus. These limitations
included a limited range two-and-a-half octave keyboard (MG-1 Plus
responds to any keyboard range), limited octave switching (MG-1 Plus adds a
three-position transpose switch), and
very
limited square-wave only
polyphony section (MG-1 Plus adds a sawtooth, mod abilities, and a range
switch). We'll get into the specifics in each section of this manual, but suffice
to say, MG-1 Plus builds upon the original easy-to-use, great sounding MG-1,
and adds to the fun with convenient, modern features.

Top Toolbar and Preset Browser
The purple strip at the top of the MG-1 Plus interface is where you’ll load,
save, and create sound presets. It contains utility functions such as
undo/redo, UI zoom and
Focus
controls, under-the-hood settings, and more.
Let’s go over them:
New- Opens a new blank patch preset. If an unsaved patch is currently open
or you’ve modified an existing saved patch, a dialog asks if you’d like to save
the patch in its current state. This greatly reduces the possibility of losing an
edited unsaved patch.
Save- Use this to save patches. There are a couple of levels of hierarchy:
Collection- This is the top level of organization, and contains entire
“sets” of presets. The
MG-1 Plus Presets
are the main included collection.
We also include a
User Presets Collection
for storing your own presets, but
you’re free to create your own collections. To create a new collections,
click in the
Collection
text field (where it says
User Presets
above) and
type a name. User-created sounds can be freely saved to any collection;
we like to keep ‘em separated for organizational purposes.
Categories- Within each
Collection
are a number of sound categories. As
with collections, you’re free to create as many categories as you like. To

Cherry Audio Surrealistic MG-1 Plus User Guide - 4
create a category, click in the
Category
text field of the
Save
dialog
window and type a new category name.
Patch- A patch is an individual sound. To save a patch, simply type the
name in the
Name
field and click
Save
.
Keywords- You can add descriptive words such as “huge,” “noisy,”
“poly,” etc., to patches to make them appear when terms are typed in the
Search
field. Use commas to separate multiple keywords entries.
Browsing Patches- Patches can be browsed by clicking the <
Select Preset
>
field. To select a preset collection, click in the area that says <
All
Collections
> or on the downward-facing arrow next to it.
Clicking on the left-side categories narrows down which patches are
displayed.
<All Presets> will show presets from all collections and categories.
<Recent> displays recently used presets.
Refresh- This is the circular arrow button to the right of the downward
arrow; clicking this checks the Cherry Audio server for new or updated
presets.
Pin
-
Clicking the push-pin icon locks the patch selection list open, allowing
fast and easy browsing and auditioning of patches. Click the icon again to
disable pin mode. when in pin mode, the up and down arrow keys can be
used to select patches.

Preset
- Step Back/Forward Arrows
- These step to the previous or next
preset. macOS [⌘+left/right arrow key] or Windows [CTRL+left/right arrow
key] will navigate through presets back and forth in the currently selected
collection/category.
Undo/Redo- These circular arrows will undo or redo the last action. It
remembers many steps, so if you really loused something up, keep on
clickin'...
Settings
-
This is where user preferences for user interface, audio interfaces,
user account, and more are configured. See the Settings section for full
information.
Importing Presets with drag-and-drop
Presets can be imported singly or en masse (as a single compressed ZIP file)
simply by dragging and dropping from the desktop anywhere on the user
interface.
If a single .*preset file is dragged and dropped, the sound is immediately
loaded and the standard Save Preset dialog appears; this lets you save the
sound to the instrument's preset browser. Note that you don't have to save
the sound to preset browser; if you just want to hear and play the sound,
click the Cancel button in the Save Preset dialog - the sound will still be
loaded.
Compressed zip files containing multiple sounds can also be drag and
dropped onto the UI. This works the same as with single sounds, but instead
of the Save Preset dialog, you'll see the Import Preset Collection dialog. The

Cherry Audio Surrealistic MG-1 Plus User Guide - 6
presets will be added as a new collection and available in the categories for
which they were tagged.
Zoom Magnifying Glass
-
Click to resize the MG-1 Plus interface. Selecting
100%
returns the user interface to native size.

Opens the MIDI controllers tab for configuring internal and
hardware MIDI controls. See the MIDI Controllers Setup and MIDI Tab
section for full information.
! (MIDI Panic)
- Click to send an all-notes-off message in case of, "why
won't this thing stop making noise?!?" stuck-note incidents.
Tempo (Standalone Version Only)- Displays MG-1 Plus’s current internal
tempo setting. MG-1 Plus's internal tempo affects the
LFO
,
Arpeggio
, and
Delay
sections when their corresponding
Sync
buttons are toggled. The
tempo setting can be changed by moving the mouse up and down anywhere
in the tempo section, or by double-clicking the number and entering the
desired BPM value.
The tempo display only appears in the standalone version of MG-1
Plus. VST, AU, and AAX plug-in versions receive tempo data from
their host DAW app.
QWERTY Musical Typing Keyboard- Opens an onscreen keyboard allowing
a standard QWERTY computer keyboard to be used for playing music notes.
For more information, see QWERTY Musical Typing Keyboard (MTK)
section.

Help - Clicking this launches your web browser and opens the help
document you’re currently reading. Which means you're already here...
Surrealistic MG-1 Plus (left side) and Synthesizer by Cherry Audio
(right side) logos- Clicking either of these displays “about” information,
and shows the version number and current registered user ID.
Focus Button
If you're using a wee laptop, the user interface can potentially be hard to
see. With this in mind, the
Focus
button conveniently blows up MG-1's view
to roughly twice its normal size within the current window size. Unlike the
Zoom
"magnifying glass" function,
Focus
doesn't affect the current window
size. By default, the patch panel section fills the current window, but the
view can be scrolled vertically and horizontally with a mouse wheel, track
pad, or Apple Mighty Mouse finger-scrolling
.
Or if you're the last person on
earth still using a single-button mouse, scroll bars will appear at the window
edges when in
Focus
mode.
Using
Focus
mode couldn't be easier - just click the
Focus
button the top
menu bar. To return to standard view, click
Reset
. There's also a superfast
key shortcut - on Mac, hold the ⌘ [COMMAND] key and click the mouse; in
Windows, hold the [OPTION] key and click the mouse. Focus can be reset
with the same key shortcuts.

Tone Sources Section
As monophonic analog synths go, MG-1 Plus is unique in that if features two
standard mono analog oscillators (i.e., capable of sounding one note at a
time), as well as a poly section that can sound up to 32 notes simultaneously.
In this section, we'll discuss the mono oscillators. Note that the MG-1 front
panel refers to oscillators as "tone sources;" perhaps Radio Shack felt this
would be less intimidating for consumers than, "oscillator."
Sync 2>1- This causes Tone Source One to force reset the start of Tone
Source Two's waveform to the beginning of its cycle, resulting in a wide
range of harmonic tones from Tone Source Two. The range of tones can be
varied by adjusting Tone Source Two's
Detune
and
Octave
controls.
Octave- Sets the pitch range for each oscillator in octaves.
Fine Tune (Tone Source Two only)- This can be used to fatten up two
oscillator patches by detuning a small amount, or for "building-in" a set
interval. Its range is a smidge over a fifth, up or down (unless the
Sync 2>1
switch is on).

Cherry Audio Surrealistic MG-1 Plus User Guide - 10
Wave Shape- These allow selection of sawtooth, square (
Tone Source One
),
or pulse (
Tone Source Two
) waves.
Master Tuning and Note Priority/Trigger
Controls
Tone Sources- The knob at the top left of the panel acts as a master tuning
control for both Tone Sources, with a range of just over +/- 300 cents.
Note Priority- Since the Tone Generators are monophonic (i.e. they can only
play one note at a time), this control determines which note will sound if
more then one key is played simultaneously.
Last- This is the default voice mode. If more than one key is pressed, the
most recently struck note will always take priority.
