What do the Global Snap and Transpose Functions Do?
The Vital Synth transpose and global snap functions can help to create automated arpeggios by snapping Vital’s output or your keyboard midi output to the grid. Global Snap will snap the midi keyboard outputs to the nearest note mapped in the global snap mapping, whereas the Transpose Snap will automatically map sounds generated by the Vital Synth to the keys you have mapped. I will provide details below and examples including a free arpeggiated sound preset using the transpose snap feature and a full demo how I created it.
How to activate Transpose Snap and Global Snap
To find the Snap functionality in Vital Synth click on the keyboard dots located on the Pitch panel. Transpose snap is the default setting with the dots turning purple when selected. Global Snap is activated when the Global Snap button is pressed and the buttons turn green. Think of the series of dots as a mapping of the 12 notes on a piano keyboard between an Octave i.e C C# D D# E F F# G G# A A# B
Transpose Snap Explained
At first glance it is easy to think the buttons don’t do anything as you can switch on different combinations of buttons and when you press your midi keyboard nothing changes. However when you assign an LFO in Vital to the Pitch Transpose control it suddenly springs into action and the LFO will trigger the notes you have mapped out in the Transpose note mapping.
The best way to start is perhaps mapping out a minor triad (1st flattened 3rd and 5th shown in the image below) and then assign a triangle LFO to the pitch transpos. Slow down the tempo frequency to 2/1 so you can hear more accurately the sound you are generating. Keep your finger pressed on the C note and you will hear Vital playing the minor triad.
Whilst the mapping is based on the C Scale it will automatically transpose the LFO if you start with a different root note. Try changing key (root note) and you will hear that the triad is still correctly played.
Vital’s Global Snap feature will snap the midi key’s input to the nearest note that you have mapped on the Global Snap mapping no matter what note you play on your keyboard. So if you have mapped 1, 3, 5 and 7 (C, E, G, B) on the Global Snap (see picture below) no matter what key you press on your midi keyboard it will automatically snap / transpose to the nearest mapped note.
A few things to note:
- if 2 mappings are equally spaced it will automatically resolve to the higher note. If the root note C is mapped then it transpose to the octave of c if that is higher
- Global Snap does not transpose as you change scales and maps directly to a C Octave on the piano. It will transpose by Octave e.g. C4, C5 etc
When to use Vital Transpose Snap and Vital Global Snap
Transpose snap probably has more uses than Global Snap. You could use Global snap to avoid hitting ‘bum’ notes in live gigs [ Wow imagine being able to play live gigs again] or live recording in your DAW but personally I am more likely to use it with Vital’s random function or an LFO to make sure that any random notes generated are in the right key of my riff.
In addition its great for for automatically creating interesting arpeggiated sequences by playing pre-determined notes with a rhythm you have designed in your LFO.
