"Smart" bass instrument (lowest note)?

You can use the MIDI Plug-in "Scripter" to do that. Below is the script, you need to paste the text into the scripter editor (press "open script in Editor", delete everything in the text editor window and paste stuff below).

Hi, the script really works fine, thanks! I've also modified it in order to play the highest note on a chord. Is it possibile to modifiy it in order to play the second (or third, fourth etc) note on a chord? I mean, if I'm playing C-E-G, the output note will be the E?

Thanks in advance!

That could be done, but it is a lot more complicated. You need an array to track the active notes and check this array on every note-on/off, if it has something like a second/third/... note. The array would be something like a virtual keyboard. Once you see, it has three notes, you can send out the second note of that chord. I'm a bit short on time, so this time I can't write you a script. Do you want to try it on your own?

Best,

DaCaptain

Thank you very much for the hint, I supposed something like that. I will try by myself, in case of success I will post here the script. Do you think this solution will be somewhat "heavy" and could introuduce some delay in response or the scripting is "light" enough?

I saw scripts for articulation switching, that are unbelievable large and still performing well. So, don't worry. Go thru the factory scripts to steal some ideas, e.g. from the harpegiator. It does have an array to track notes.

Hope this helps!

DaCaptain

I'll do, thank you very much! 🙂

Loving the script as well. Any chance you could share the modified version that plays only the highest note?

Been using the script posted to fill out our low end and it's working very nicely. Pianist can play as normal, and get get a bass too. It's actually cleaner than having a bassist and pianist together, because the parts match perfectly.

With Christmas season here, I'm hoping to add a few bell and chime sounds to the setup, and would love to have those on only the highest note.

Thanks to all of you who have contributed to this.

I think, you just need to change a few lines of code.

Change this line

if(Pitch < BassNoteNumber)

to this

if(Pitch > BassNoteNumber)

Then it picks the highest note.

The initialization BassNoteNumber = 1000 needs to be changed to BassNoteNumber = 0. This happens in two places (line 14 & 72).

To reduce confusion about the variable's name, change BassNoteNumner to LeadNoteNumber, e.g.

Hope this helps,

DaCaptain

That worked beautifully, thank you. Now a random church in rural Kentucky has you to thank for the bit of Christmas magic that'll add to the sound.

For anyone who needs it, here's the script with Cap's modification for highest note. I kept the name "bassnote" to make the change easiest.

// Script start

var BassNoteNumber = 1;

var NoteIsOn = 0;

function SwitchNote(NoteNumber, Velo, state)

{

if(Velo == 0)

return state;

if(state == 0)

{

var on = new NoteOn;

on.pitch = NoteNumber;

on.velocity = Velo;

on.send();

}

else

{

var off = new NoteOff;

off.pitch = NoteNumber;

off.velocity = Velo;

off.send();

}

state = 1 - state;

return state;

}

function Reset()

{

if(NoteIsOn == 1)

NoteIsOn = SwitchNote(BassNoteNumber, 1, NoteIsOn);

BassNoteNumber = 1;

}

function HandleMIDI(event)

{

if(event instanceof NoteOn)

{

var Pitch = event.pitch;

if(Pitch > BassNoteNumber)

{

if(NoteIsOn == 1)

NoteIsOn = SwitchNote(BassNoteNumber, 1, NoteIsOn); // switch old note off

BassNoteNumber = Pitch;

NoteIsOn = SwitchNote(BassNoteNumber, event.velocity, NoteIsOn); // switch new Note on

}

}

else

if(event instanceof NoteOff)

{

var Pitch = event.pitch;

if(Pitch == BassNoteNumber)

{

if(NoteIsOn == 1)

NoteIsOn = SwitchNote(BassNoteNumber, 1, NoteIsOn); // switch old note off

BassNoteNumber = 1;

}

}

else

event.send();

}

// script end
