Making a Mono Mode

Casmat

Hey!

I have a question for making a mono legato in hise.. I’m thinking of making a legato which glides by taking the sample playback position of the original note and starting the new note at that sample position and then adding a pitch plus volume fade between the two. So basically let’s say C is being pressed, then E is pressed, when E is pressed, E starts playing but at no volume and the pitch fading takes place along with the volume xfade which theoretically make the legato… right? Question is I’m wondering if this how I go about a legato which does the sample position transferring?

Thanks!

@Casmat That will work (if you want to make it better you need to do this xfade/pitch fade with each pair of notes between the first note and the last).

The sample position isn't important (or maybe it is to you?). Just as long as the samples are looped and the loop doesn't include the transient.

By the way, my legato script does this :)

@d-healey thanks David! Will update you with what I find!

By the way, my legato script does this :)

GPL though :confounded_face:

The functionality im planning on implementing is this:

Mono Retrigger Mode, no glide, just basic retrigger
Mono Legato Mode, glide! Basically what you said in your post
Anchor/Last note retrigger, if a note is held and another note is pressed and let go, the note held is played, both for legato and retrigger mode

@d-healey definitely! I’m now debating between going for the sample switching method of legato vs going for the pitch glide method of legato.. I tried your legato script to see how it’d sound l, but after messing with the controls for a while, when it glides up/down, you can hear all the samples in between and they all play from the start, is there a way on your legato script to make it sound more “glidey” instead of that strumming sound?

d.healey

@Casmat yeah you need to use a start offset modulator and drop in another script to control it

I made some changes to your script to get last note retriggering working! Most everything works, except for one thing, I tried finding the cause of the issue (you may see some console print statements scattered), but unsuccessful. Basically, the problem occurs when you try to "glide" from two notes. Lets say you press C, then while holding C, you press E, E plays, but as soon as you let go of C, E stops playing.

    if (Message.getNoteNumber() == noteNum && eventIdQueue.length > 0 && time.getValue() == 0)
    //...
    if (eventIdQueue.length > 0 && time.getValue() > 0)

I think i traced the problem to these if statements where the first one does what I mentioned above, but when I deleted the Message.getNoteNumber() == noteNum line (the second if statement), Instead of E stopping, It gets retriggered. Any ideas to fix?

Edit: there's also probably a lot of unnecessary code since i didn't replace most of your existing code which may/may not be functional due to my changes... I only removed the lastTuning variable since it was the one causing the pitch issues, all to fix was just add a rootNote var

Thanks!

@Casmat

eventIdQueue.push(
{
"eventId": Message.getEventId(),
"noteNumber": Message.getNoteNumber()

This kind of thing is slow/inefficient. Use a midi list:
ml.setValue(Message.getNoteNumber(), Message.getEventId());

if (!noteNum == undefined

This logic is confusing, do you want to check if noteNum is defined or if it's not defined?

You probably want to use if (!isDefined(noteNum))

Same here

if (!retrigId == undefined)

Don't put if statements on a single line, it makes the intent of the code less clear at a glance.

@d-healey I’m stuck trying to figure out how I can use a midi list in my case.. I tried to read the docs but there’s little info, how can I use the midi list to replicate the array system I had? In the previous system, I had stored the event Id and note number in an object that is created for each note on and deleted on the note off. The objects could be ordered in a list such that the last value would be the next one in line to be retriggered. How could I replicate this? And would this solve notes turning off when others are released?

This shouldn't be needed. In a mono system there is only ever one active note and one old note. With retrigger you have potentially two old notes. So at max you need to keep track of those three notes.

And would this solve notes turning off when others are released?

If you are making artificial notes you still need to turn them off.

A midi list is an array with 128 elements that is optimized for this kind of task.

To create a midi list use:

const eventIds = Engine.createMidiList();

To store the event triggered by note 60 (for example):

eventIds.setValue(60, eventId);

To store events as they come in to on note on you would replace 60 with Message.getNoteNumber() and eventId with Message.getEventId(); But you can also store artificial events too.

To the get the eventId of note 60:

local eventId = eventIds.getValue(60);

@d-healey ohhh, I’m trying to recreate Vital’s mono mode on the “newest” voice setting which keeps track of held notes and prioritizes the newer/latest notes. I’m guessing I wouldn’t be able to hold that much note numbers in midilists, right?

If you are making artificial notes you still need to turn them off..

I thought I took care of all the hanging notes, are there more I didn’t get? The problem is that is I’m doing a regular string of notes, when I let go of the old note while holding a new note I want to hear, the new note retriggers again when the old one is let go

I'm not familiar with that

A MIDI list is just a fast array, so you can definitely use it for this. You just might need more than one.

I thought I took care of all the hanging notes, are there more I didn’t get?

I dunno, I didn't try it. I was responding to this question

And would this solve notes turning off when others are released?
