[SOLVED]Tweaking ADSR and sustain parameters in Gigedit

Post by prasadbrg » Thu Dec 24, 2009 10:06 am

Season's greetings to everyone!
I'm relatively new to sample editing, so please excuse me if I get my terms mixed up...! I'm working with a string ensemble .gig file. For the most part, I found things fairly intuitive: I've been able to change the attack time, and introduce some release, which suits my needs. I'm using a keyboard and a sustain pedal in a live context.

However, I need my sample to do the following:
  • Have a nonzero release (i.e. sound decays off *after* key release). Let's say this time is 3 seconds
  • when I hit the sustain pedal before the sound has completely decayed (i.e. during the 'release' cycle) , i.e. within 3 seconds, the note which is still sounding must not be sustained
  • only new notes must be sustained when the sustain pedal is hit, and not the previous note which is still in the 'release' phase
I believe I've just described the effect of a sustenoto pedal; however, coming from a non-western musical background, I'm not quite sure. :?

Here's where I'm stuck: If I uncheck the "Infinite Sustain" box in the "Amplitude(1)" section of Gigedit, then the previous note is not sustained (while sitll decaying), but this 'release' is cut off as soon as I hit the sustain pedal. OTOH, if I check this box, then the previous note is sustained...!

To sum up: When the sustain pedal is hit while the previous note is still decaying after key release (i.e. in the "release" phase), I want neither the previous note to be sustained nor the "release" sound to be cut off.

I hope this is less confusing than it sounds!

I have other applications by which I can make the sustain pedal send sustenoto midi cc messages in place of sustain, if that is required.

Any help in this regard would be appreciated.
Cheers,

Guru

A quick update. I actually tried changing the midi CC of the pedal from 64 (sustain/damper) to 66 (sustenoto).
The result: the exact inverse of what I wanted. Sustenoto seems to make the future notes unaffected by the sustain; I need the previous notes to be unaffected by the sustain.

Hope this helps clarify the situation. Any help would be apprectiated!

Solved! :D

By trial and error, I figured out what needed to be done:
What I wanted was the "Decay 2" parameter to be *slightly* above the "Release" value.
Works rather nicely now!

Thanks to the developers!
