Using Automap
The automap function can be used as a quick way of creating a key map, or as a good
starting point for further adjustments of a key map.
Automap works under the assumption that you intend to create a key map for a com-
plete instrument, for example a number of samples of a piano, all at different pitches.
1. Load the samples you want to Automap.
Now you have three options:
D Trust that the root note information in the files is already correct.
D Manually adjust the root notes (and tuning) for all the samples.
D Use “Set Root Notes from Pitch Detection” to automatically set up the
root notes.
2. Select all zones you want to automap.
3. Select Automap Zones from the Edit menu or the NN-XT context menu.
All the selected zones will now be arranged automatically in the following way:
D The zones will be sorted in the display (from top to bottom - lowest key
first) according to the root keys.
D The zones will be assigned key ranges according to the root keys.
The key ranges are set up so that the split between two zones is exactly in the mid-
dle between the zones’ root notes. If two zones have the same root key they will be
assigned the same key range.
Layered, Crossfaded and
Velocity Switched Sounds
Creating Layered Sounds
You can set things up so that two or more zones have overlapping key ranges - either
completely or partially. This way you can create layered sounds, i.e. different samples
that are played simultaneously when you press a key on your keyboard.
In the picture above, you can see a set of piano samples at the top, mapped across
the key range.
Below these are a set of string samples that also span the entire key range.
Whenever you play a key within this keyboard range, the sound produced will be a
combination of the piano and the string sample.
In addition, in the example above, the user has arranged the piano samples into one
group and the string samples in another. This is convenient since it allows for quick
selection of the entire piano map, for example for balancing its level against the
strings.
About Velocity Ranges
When zones are set up so that their key ranges overlap – completely or partially – you
can use velocity switching and crossfading to determine which zones should be
played back depending on how hard or soft you play on your MIDI keyboard.
This is done by setting up velocity ranges, with or without crossfading.
Each time you press a key on your MIDI keyboard, a velocity value between 1-127 is
sent to Reason. If you press the key softly, a low velocity value is sent and if you press
it hard, a high velocity value is sent.
This velocity value determines which samples will be played and which will not.
Let’s say for example that you’ve mapped three different zones across the same key
range:
