How do I create a sustained sound?

How do I create a sustained instrument on the modx? I picked the samples of a mellotron sound but I simply cannot figure out the way to do loop the samples.
Thank you so much!

Step#1 - You need to buy a Sustain Pedal and plug it in.

Judging by some previous threads, I highly recommend buying a Yamaha Pedal, they aren't expensive, and guaranteed to work with your MODX.

I bought a Yamaha FC4A, it worked immediately.

I ll explained better:

I already have a sustain pedal. It is not that.
I am talking about creating a sound like strings for example that has sound as long as I keep the keys pressed. The pedal is not the same thing, i think every pianist an agree to that. Now, a tutorial online said that modx cannot do this, i didn't want to believe it, but it appears to be so

This guy says there is no way to loop a sample in the modx.
Is he right?

I misunderstood. I don't know anything about User Waveforms and Keybanks.

There are "Factory" Mellotron Samples in the MODX however if you want to use those.

Yes I heard them and I dislike them.
Thank you anyway

He is right when he says that you can't loop the sample in the MODX, as the MODX doesn't have a sample editor.
He is wrong when he follows up by saying it's not possible with free tools.

Try free audio editors that let you set loop points (for example Wavosaur or Endless WAV), should work.

The best way would be John Melas' Waveform Editor ( http://www.jmelas.gr/montage/wave.php ).
It's not free but it's purpose made to work with Montage/MODX waveforms and it's also an excellent editor for backup/library files. Well worth the money IMO.

Much appreciated.
All the best

The imported .WAV or .AIFF files require the standards-based meta data for loop points (time) and loop type. It's possible to use free tools and I have both Wavosaur and Endless Wav (PC and Mac - Mac worked better for Endless Wav for me but I haven't done a lot of work with it). JM Tools waveform editor is a more polished and purpose-fit solution at cost. The other path would be to use a previous product with both sample capabilities and compatible file outputs like the Motif XF.

BTW: the loop points are properties of the internal waveforms and it is possible there are internal waveforms that have loop points are there but are imported into a Performance that decays due to the AEG and not the sample itself.

You notice if you pull up "Init Normal (AWM2)" using [CATEGORY SEARCH] - this is a piano waveform that exhibits the property you want already. You hold down the key and the piano sound loops "forever" and does not decay on its own until you let go. So recall "Init Normal (AWM2)" as a starting point then go to Element1 and start previewing waveforms you want. You'll notice the loop points are already there.

1) Touch Elem1
2) Choose "Osc/Tune" menu
3) Touch "Name" in upper-right
4) Choose "Category Search"
5) Filter by "Strings" main and "Ensemble" sub or any category and sub-category you want
6) Select any waveform and hold a key to preview

You may already have what you need inside the MODX itself without having to create your own sample.

I would guess your experiments before have an element "Amplitude" -> "Amp EG" setting where Decay2 has a level of 0 with some time setting (For Decay 1, with a non-zero level - to hold the note for some amount of time before the decay to 0) such that the sample is cut off by the AEG even though the sample itself is actually looping (and would loop "forever" as long as you hold a key if the AEG was properly configured)

There's not a reference, but by previewing factory preset waveforms - there are not a lot of "one shot" (non looped) waveforms. Mostly the samples are looped to begin with.

The "Sound FX" and "Drums" categories have primarily (and maybe all) one-shot samples. But primarily (maybe all) of the other categories all have looped waveforms. That's a ton of looped samples already available.

Use AEG properly and I believe you're set.

Thank you very much.
You really gave me a lot to check!
You really know the subject!

Hopefully it is helpful. The easiest starting point for what you're trying to do is make sure to start with "Init Normal (AWM2)" since so many of the other parameters are already set for you. This setting does not scale volume with your key velocity - velocity response is fixed more like a mellotron's on/off behavior (no matter what the velocity is) if you ignore the effects of digging in to make the tape head push into the tape.

As you dig into what you were trying to do before you should notice the AEG was the issue with hearing the looping you were after and can go back to editing more "finished" presets like you may have been doing before.
