Hmm what do you think about adding envelope detector, and loop will be generated if envelope reach threshold point (with something like schmitt relay to avoid attack looping) So it just be three parameters - threshold, loop length and hmm fade depth ?

edit:
Proposed options in duration panel:
Hold
Threshold
Loop length
xfade depth
Release
and switches
x discard attack
x discard release
x note end detection

So key down time will be sum of hold time and looplength, and then key up and vsti will be sampled till release time ends or silence when silence will be detected

edit:
Two years ago i created simple sample editor and after chaining and looping i can add that to VSTi dumper

It works fine even with >30mb .wavs

I mentioned this in my first post in this topic.

How about ...
ADSR rebuild from the VSTi patch ?
(at least activate articulation,
so ADSR will work right away with sfz.)

The problem is NOT the attack, but the release fade.
If you can detect WHEN the level is dropping
and set the loop end just before, this would be great !

Imagine a 10sec sample:
If we know the level starts to drop at 7sec
we set the loop end to 7sec.

Now we set the crossfade lenght to 50%,
counting from the loop end point to the sample start.
(for this exemple. (might be 75% too))

So the loop start would be at 3.5sec
(should be enough to NOT include the sample attack.)
Now we can try to use 50% of those 3.5 sec to do the
crossfade, hm... merging, with the end of our loop range.

The result should be a very smooth loop without much modulation.

Sorry all this is very hard to explane,
please ask me when something is not clear.

CAUTION !
This was my GENERAL explication of crossfading a
VSTi Dumped sample.

To make this work for ALL multisamples of a dump,
we must consider a few more other things.

CCT, let me know when you are ready for it.
Them we can do this using email or PM.

So write e-mail to me, it is included in VSTi dumper doc

I will be ready at monday

Now i have some other things to do.

Ok, I will.

In the meantime, maybe...

You could add some memory buttons for the:

Velocity splits
and the
Dump keys

The black keys of the keyboard are quite hard to klick,
maybe you can make them a bit wider.

Just found, that a dump-transpose would be helpful.

This E-Piano sounds right where its dumped,
but it would be better if the splits,
would be a few octaves higher.
(playing the same pitch)

Or a transpose VSTi function can do the job too.

Edit number 4 or so:

You cut the dumped notes very hard at the beginning,
this results in clicks on some sounds.(percusive stuff)
Just add a few zero samples automaticaly when dumping, to prevent this.

Ok, so next time i will add save config, load config buttons to store layer config, with autoload function.

Here small update:
http://audiolabz.com/vd0322.rar

- more compatible VST host
- you can play notes using right mouse button and on screen keyboard.

Wheel control is almost ready -> so the next release will contain vst chaining with some hmm dry/wet etc...

Very nice CCT, and not monday yet.

At least not here, but in 3 hours.

Now I will try your new update !
Thanks !

Nice, CCT, will try it out in very few hours!
Any plans on exporting waves instead of SF2?

Midiworks · Post by **Midiworks** » Sun Dec 05, 2004 2:28 pm

CCT, vd0322.exe, saved as sf2 only has empty wav files inside.

CCT · Post by **CCT** » Sun Dec 05, 2004 3:04 pm

Hmm what plugin did you tested ?
hmm i checked charlie demo and i have wavs in sf2 after
dumping

ZeroVector..., ok tried with Hydra and that works !

Next update ;]

http://audiolabz.com/vd0323.rar

0.3.2.3 - 05/12/2004
- plugins from Native Instruments should work now (tested with Intakt demo version)
- .wav dumping now supported (currently only 16bit/44khz, without dithering and clipping :/)

A) Windows (XP Pro, SP2) is constantly telling me it's crashing. When I drag the Window out of the way (instead of closing it) I can continue working though. Weird.
B) How do I play notes? Rightclicking? Is there MIDI support planned?
C) How do I setup the soundcard (or driver) which I'd like to use with it? Does it only use the preferred Windows device?

Keep up the work!

Cheers.
