Mozaic basic midi pad controller

eross

trying to learn Mozaic and the syntax. are there any basic scripts for a simple. push a pad and have it send a midi note out to a synth.?
that way i can get a better feel for how the language work

Try this and post any questions about how to do more like assign notes to PAD #'s.

@Description
   Basic PAD Example
   hit any pad and send C4 out on Channel 1 - velocity 80
   stop the C4 note 200 msec later
@End

@OnLoad
  // Show the PAD Layout GUI
  ShowLayout 2 // all pads
  pad_note = 0
@End

@OnPadDown
  // LastPad will show which PAD was pressed down
  pad_note = LastPad
  SendMIDINoteOn 0, 40, 80
  SendMIDINoteOff 0, 40, 80, 200
@End

yeah cool this works.
so how do you assign notes to pads?

@OnPadDown
  // LastPad will show which PAD was pressed down
  pad_note = LastPad
  SendMIDINoteOn 0, 40, 80
  SendMIDINoteOff 0, 40, 80, 200
@End

so how do you assign notes to pads?

You must add statements to convert the pad_note variable to a specific pitch.
I like to create a scale array:

// C major scale
notes = [40, 42, 44, 45, 47, 49, 51, 52]
and use the pad_note number to point to the Notes to play:

SendMIDINoteOn 0, notes[pad_note], 80
SendMIDINoteOff 0, notes[pad_note], 80, 200

Good next step question.

Complete Version 2 - test by hitting more pads... the first 8 will send a note. Add more notes to the "notes" array to use all 16.

pad_note = LastPad
SendMIDINoteOn 0, notes[pad_note], 80
SendMIDINoteOff 0, notes[pad_note], 80, 200
@End

The thing that takes some time to understand is that you basically have 2 methods to
make something happen in the future...

1) add a delay to a SendMidiOut as parameter 4. Then that delay gets managed by Mozaic.
There's no concept of "idle" or "wait until" you just submit a request to do something at a time in the future.

2) the second option is to use timers or Metronome events and request the SendMidiOut on that schedule. The "OnTimer" and "OnMetroPulse" are there for these use cases.

People keep thinking everything runs as a list of commands that spans time in our concept of time but the reality every event is processed in less than a millisecond and the program idles pending a new event.

It just takes mastering 1 and 2 and you can do magic.

Echoes are typically delays or note releases and OnMetroPulse can do the "Piano Roll" style of logic to make sequencers.

I should mention that there's also and OnPadUp event and you can send out the Note Off with that physical event:

@OnPadDown
// LastPad will show which PAD was pressed down
pad_note = LastPad
SendMIDINoteOn 0, notes[pad_note], 80
@End

@OnPadUp
pad_note = LastPad
SendMIDINoteOff 0, notes[pad_note], 80, 200
@End
