MOZAIC - Create your own AU MIDI plugins - OUT NOW!

Keyb

Inspired by another thread, I was thinking that I could use my BT-106 Airturn as a Bluetooth sustain pedal. And I thought about Mozaic!

Do you guys think it’s possible to create a plugin that converts "QWERTY’ keystrokes to MIDI messages?

Very easy to convert one specific MIdi event in to another going out button done and up to sustain on and off.

We can’t find an app that converts keyboard events into midi events. Dev’s need to make an AUv3 for us.

Or just use mfxConvert and not need to do any programming.

No, that's not possible with Mozaic.

Sidecar MIDI Controller by Secret Base Design can do that in a somewhat limited fashion.

What is the fastest way to reset the round robin script when a new key is struck? So hit C and it plays three round robin notes. Hit D and I want it to start on D and play three notes (not the interval it last played when striking C). Thoughts?

Anyone?

Round robin implies some application behavior. Mozaic accepts MIDI in and has no precise concepts for Round Robin. So it’s hard to assist you.

To change script behavior have it do something when a unique event comes in to request a change back to some state.

Remember Mozaic manages 1 event at a time and we get clever to make it all feel linear but it’s really a State Machine that has memory by changing and evaluating variables.

So for a reset send midi note 127 or something you’d never hear and code the “reset” of variables to change behaviors.

That script doesn’t have a reset function. Here’s a modified version that adds a reset knob. Double-tap it, turn it past 12 o’clock, or set the AU parameter Knob 2 to 64 or greater to reset the round-robin to the base note.

(Note, for others - the base script was posted by @Brambos on patchstorage: https://patchstorage.com/round-robin/)

  // state saved or initialise now?
  if Unassigned numnotes
    numnotes = 3
    roundrobin = YES
    pointer = 0
    SetKnobValue 2,0
  endif 

  // set up UI
  ShowLayout 2
  Call @MyKnobLabels
  //LabelKnob 2, { }
  LabelKnob 3, { } 
  LabelKnobs {Mode} 
  LabelPads { }
@End


// Handle MIDI input

@OnMidiNoteOn
  if roundrobin = NO
    pointer = Random 0, numnotes-1 
  endif

  newnote = MIDINote + pointer
  SetNoteState MIDIChannel, MIDINote, newnote // remember what we did
  SendMIDINoteOn MIDIChannel, newnote, MIDIVelocity

  FlashPad pointer

  Inc pointer
  if pointer >= numnotes
    pointer = 0
  endif
@End


@OnMidiNoteOff
  newnote = GetNoteState MIDIChannel, MIDINote
  SendMIDINoteOff MIDIChannel, newnote, MIDIVelocity
@End


@OnMidiInput
  // if MIDI input is not a note on/off then send thru unchanged...
  if MIDICommand <> 0x90 and MIDICommand <> 0x80
    SendMIDIThru
  endif
@End


// GUI Stuff

@OnKnobChange
  value = GetKnobValue LastKnob
  if LastKnob = 0
    numnotes = Round (TranslateScale value, 0, 127, 1, 16)
  elseif LastKnob = 1
    roundrobin = (value < 64)
  elseif LastKnob = 2
  // Add a round-robin reset knob
    if value >= 64
      pointer = 0
      //reset the knob position so that double-tap will trigger it
      SetKnobValue 2,0
    endif
  endif

  Call @MyKnobLabels
@End



@MyKnobLabels
  LabelKnob 0, {Notes:}, numnotes
  if roundrobin
    LabelKnob 1, {Round}
  else
    LabelKnob 1, {Random}
  endif
  // Add a round-robin reset knob
  LabelKnob 2, {Reset}
@End


@Description
(Modified version to include a round-robin reset. Double-tap, turn past 12-o'clock, or set AU-Parameter Knob 2 to 64 or above to reset. @wim)

This script applies a round-robin or random-robin algorithm to incoming notes. 
E.g. when the number of notes is set to 3 and you repeatedly trigger C3, this script will play C3, C#3, D3, C3, C#3, ... instead. 
When you send C4 it will send C4, C#4, D4, etc. So you only need to trigger the base notes.

When random-robin is selected it will do the same but randomly pick notes from the range instead.
@End

wim

It seems to me like the round-robin should reset automatically when a new note is triggered. Wouldn’t that make more sense?

McD

@wim thanks. I didn’t see the context for the question. But didn’t see anyone taking up the request either.

That's exactly my point! Your revised script above adds a knob to do the reset (thanks for that!), but I'm suggesting that it is reset on the fly when a new note is played.

It works perfectly! And I used your new code to better understand Mozaic so win/win. Thanks a bunch, @wim.

Would be cool to get a "branch" to Bram's original for those who come seeking the resettable version.

wim

Yeh, I’m not sure the cleanest way to approach that. I wouldn’t want to post it myself really. I’ll just leave it as is and if leave it up to Bram if he wants to incorporate the change or to implement it differently.

similar to things people have been making with Mozaic already

if someone fancies creating something similar?! original input on one channel and generative on another 😎

@SpookyZoo does it have MIDI out though? Seems to be a VSTi only, not a MIDI processor, is that correct?

Yeah I think you're right. However Ólafur does go into a fair amount of detail about what is going on with the different machines, so theres more info for anyone wanting to make a Mozaic midi version.

I've started using Mozaic recently, and while it's great, the script editing process is not. Yes, you can do select/copy/switch-to-editor/paste then do your editing, and when done reverse the process back. But this is not developer-friendly. It should strike any developer as quite odd to have text mixed with binary data in the .mozaic project files

-- It discourages use of a separate editor app.
-- It strongly discourages use of a separate editor for minor tweaks.
-- It strongly discourages use of a good editor for a (very common kind of) development process where you're continually making small changes, then running code to test how it works.
-- It makes it quite difficult to use git or other version control on the text.
-- Strongly discourages any kind of efficient collaboration between people working on the same script.

It seems like it wouldn't be very hard to add functionality to make text editing in a separate app more seamless. I'm no expert on iOS programming, which I know has odd security-related restrictions on an app's access to folders. But it seems like this scenario would be pretty easy to add, and would have big benefits:

1. If someone wants to develop with separate text files, then they can create folder in Files app, name it 'MozaicScripts', e.g..
2. Then within Mozaic they can authorize Mozaic to access this folder. I believe Mozaic can save a URL so they don't need to re-authorize each time Mozaic is started up.
3. Then Mozaic can start to:
   a. Upon save, Mozaic saves script to a text file in the user's designated folder (if any), and also saves (as it does now) the text in the .mozaic file.
   b. Upon 'Load' check for whether text file with later timestamp than the .mozaic file exists in user's designated folder. For example, if 'myproject.txt' in the user's designated mozaictxt folder was modified today, and user loads a .mozaic project that was last modified yesterday, then Mozaic automatically loads the script in the text file in place of script in the .mozaic file. This will seamlessly load the text file that was changed in separate text editor.

I haven't thought this fully through. But this, or something like this, would seem to be quite easy to add to Mozaic. It also seems like this would greatly increase ease of editing Mozaic scripts, allow easy use of github (with Working Copy app, for example), and make it much, much easier for people to collaborate on the same script. Someone might reply that people don't really collaborate on Mozaic scripts, so it's not really that useful. To this I would say, duh, there's not much collaboration because it's so damn hard right now! Make it easier and I can't help but think that it would help grow use of Mozaic by a lot.

The .mozaic files include the state of knobs and variables at the time of save. That's the binary portion you see there. Your proposed mechanism would need to handle that in some way.

No, that would stay the same as it is. Saving of .mozaic project file would be the same as now. Just adding a step that, if user has designated a mozaictxt folder, then the text is also saved to separate file in that folder.

When running Mozaic in Standalone mode does any MIDI flow out of it?

Got me all excited then, I’ve been trying to figure out how to drive touchviz (CoreMIDI only) from AUM so I can use mozaic scripts and suddenly thought you’d solved it (and removed another app from the chain)

Alas no

So, touchviz doesn't show up as a routing destination in AUM? Is it one of those apps that doesn't show a virtual port and will only let you connect to an app that does show one (AUM doesn't)?

If so, then there are some ways around this. One is to use Audiobus as an intermediary. Basically, you sen the midi out from AUM to Audiobus, then from Audiobus' virtual out to touchviz. Another is to do something similar with MidiFlow.

Sorry, I'm just guessing here since I don't own touchviz, but that's the general drill for situations like this. Maybe someone who owns the app can help out.

Krupa

Ah cheers @wim no it doesn’t show in aum, nor does aum show in touchviz as an input, though weirdly it does as an output... I only have ab2 but this could be the trigger that gets me into the ab3 gang if it works...

I did get it going with FreEWI acting in between but that setup was a bit flaky and I had a couple of crashes and constant high latency so I wasn’t keen to pursue any more paid for solutions until I knew they’d be solid...

MidiFlow and MidiFire are solid alternatives, but AB3 is worth having for many, many reasons. I can't guarantee any of these will actually fix the issue for you though, since I don't have touchviz.

Krupa

Absolutely understand, I’m talking with the touchviz devs about it as well, and I know that ab3 is probably good for me but I’m really happy with aum right now, use ab2 just for hosting stuff that won’t otherwise link up but that starts feeling complicated for my liking

Thanks @wim

Thanks @wim

You can stay with an AUM centric workflow and just use AB3 for this one bit of routing if you want. It's just acting as an intermediary to pass the midi along.

It would be very nice if @j_liljedahl exposed a virtual output port for AUM for apps like this that need it.

FWIW, AB3 is also very useful for integrating apps that support midi clock and not ableton link.

good point. it also solves the issue of apps that have Link, but not Link Start/Stop.
