StreamByter AUv3 (Out now!) - All the Midi-Control you could ask for!

obijohn · June 2018

IMHO "humanizing" velocity and note length get you the most bang-for-buck, and these are both doable currently in StreamByter. Note position can be randomized as well, but as mentioned it could only be "behind" the beat, with nothing randomized to occur before the beat. However, again IMHO, the best "humanizing" in regards to note position is behind the beat. When notes occur before the beat it can sound plain sloppy very very quickly (again IMHO; also this might be what you want sometimes, and that's ok too). So anyway, for me, StreamByter can do 90% of the "humanizing" that I'm interested in and that Cubasis still doesn't support.

One workaround for getting some of the randomization of note position to happen before the beat: record the midi track, then shift it to the left a tiny bit in your DAW, and THEN use the SB code for humanizing position. So yeah, still doable.

Just a quick & fun experiment with the StreamByter AUv3

A single slider created in Midi Designer outputting midi CC# 71 on Midi Channel 5.

The StreamByter code sends a note on and note off message to Zeeon synth based on the value of the slider.

If it’s lower than value 64, a C3 midi note is sent.
Higher than 64, then a C4 is sent instead. * see the labels show which is being sent.

With this code a value of 64 is silent.

StreamByter code. (No real world use, just testing a few of the functions together on this one)

   IF M0 == B4 47 # ask if the midi message is CC71 on channel 5
     SET LB0 3C +N # if yes, set the label to show midi note being played
     IF M2 < 40 # ask if the slider value is less than 64. (40 in hex)
       SND 94 3C 7F # if yes, send a note-on of Middle C with a value of 127
       SND 84 3C 7F +D200 #also send a note off with delay of 200 milliseconds
     END
   END

   IF M2 > 40
     SET LB0 48 +N
     SND 94 48 7F
     SND 84 48 7F +D600
   END

M0 is the first byte of midi message.
B4 is midi channel 5.
47(hex) is 71, the CC# here.
LB0 is the left hand label.
The +N flag sets the label to display the musical note.
M2 is 3rd byte of midi message, in this case the slider value. Less than 64 (40 in hex)
SND is a command to send data.
94... 9 is note-on, 4 is midi channel 5
84...8 is note-off.
3C(hex) is middle C, (Midi note 60) 7f is the note on value, (127)
The +D flag sets a delay on the event. In this code the higher note lasts longer in milliseconds (600)

So here's a velocity humanizer for StreamByter. It "randomizes" the velocity within a +/- 8 range. And a screenshot, showing it in use in AUM. Bassline was set to a flat 80 velocity, and the StreamByter AU code is set to display the note and updated velocity in its two labels. I'll add a note position/length humanizer this evening or tomorrow and post that as well.
Edit: turns out the MAT function can only do one operation, editing that below to do the two operations over two lines. See my later post on a more fully worked out “humanized”.

# Humanize velocity
IF M00 >= 90
  IF M00 <= 9F
    IF M02 > 00
      # display the note in the left panel
      SET LB0 M01 +N
      # random +/- 8 velocity
      MAT M02 = M02 + RF
      MAT M02 = M02 - 8
      # but don’t exceed 127
      IF M02 > 7F
        ASS M02 = 7F
      END
      # display decimal velocity in the right panel
      SET LB1 M02 +D
    END
  END
END

Looks interesting and more future proof than puredata in iOS .
But it will take time to learn
Are there arrays and examples of using them ?

Yes but the syntax isn’t what you might be used to:

Maybe this is kinda random but I love that commenting each line of the code is the norm with streambyter. I work with a guy who thinks the "elegance" of his code is all of the comments anyone would ever need. smh.

Thanks, @obijohn. Works like a charm.

Woa. That's a lot deeper than I realized. Like, deep enough to do considerably more than the sort of input adjustments most of us turn to SB for. A desktop environment of sorts would be handy for exploring the language constructs further. Especially if it supported some sort of introspection (see the value of a variable by hovering your mouse, say). I'm not sure how far I'll really get into it all by typing into an AU window.

I see that MIDIFire is available for MacOS ($30) but it's not clear to me from the description if that offers any nerdly grammar tools/developer training wheels. Anyone use it?

Or you could just set that velocity “variation” percentage in the Rozeta plugin to 5% and get the same thing out of the box

Not every app is a brambos app though. But yeah, kinda funny choice for the example source app.

Hey man.

I reached out and asked Nic. Here's his reply...

The mac version is almost completely identical. Really there are just a
handful of rules in Stream Byter and the compiler does tell you which line is
incorrect! However, there is no contextual assistant, I'm afraid.

Personally I write all the SB code in the mac version; it's a bit easier and
you can just copy the mfr file to iOS. Although using a bluetooth keyboard on
the iPad works really well also for editing in my experience.

And when I say SB only has a handful of rules:

XX = XX variants
SND
ASS
IF/END
MAT
SET

and some understanding of the variables and I mean, that's it!

It's not that complex and the guys who designed MIDI itself really outdid
themselves with such a concise and smart protocol. 30 years on and it's
essentially the same core.

Regards,
Nic.

How will MDP provide an interface to this app? I mean there needs to be some kind of graphical gui for Stream byter... Not some arcane hex-based text editor nonsense...

Why not just have a usb punch card reader to program it?

Yeah, this example was just meant to show that StreamByter could supply velocity "humanization" to an incoming MIDI stream, not that Bassline couldn't do that on its own. In hindsight I probably should have picked a better example, I certainly didn't mean to imply that Rozetta didn't have that functionality.

Oh, you meant the GUI of the app instead .
Could recommend learning PureData in desktop and launch MobMuPlat app , but the app isn’t frequently updated ,plus I don’t know if it makes it to next iOS versions (requiring metal for graphics)

What I'd love to see is this:
https://www.plogue.com/products/bidule.html

On IOS

Audulus is too low level for quick jams (at least for me)
ZMors is sooo cool, but midi in out is flakey (but the fact that it can host AU and IAA is seriously sick)

But Bidule on iOS?! Holy crapballs that would be awesome!

StreamByter is for midi manipulations.

Actually they do, because they can all manipulate MIDI data.

I hope this thread never gets deleted or lost! There’s a ton of good information (that’s only likely to grow). I used to have a real life LED hex pocket calculator in my early software days. I bought an el cheapo app for doing this yesterday:

This would be even greater if there was a widget to convert at least the decimal numbers into hexadecimal. Should probably be pretty straight forward to add that.

This looks like rocket surgery to me and I’m a programmer for a living. Does it also brew coffee or is that an IAP?

Great stuff though, truly impressed. Congrats on the dev for another formidable app.
