Patch help: Make it sound like reverse tape effect (Polybrute 6)

Brute PolyBrute
#1

I’m trying to create a patch that sounds like music being played in reverse, but it’s quite challenging to do without a more flexible VCA envelope or velocity release as a modulation source since I’m shooting for the volume to start low and then suddenly go up right after I release the key then go to complete silence. One thought I had was to try to use the VCF and Mod envelopes together with the VCA envelope to create an envelope affecting the volume that has the right shape, but the VCA envelope seems to put a ceiling on the volume of the oscillators, so I can’t use the other two envelopes to increase the volume. Any ideas (including a patch in one of Arturia’s sound banks that does something like this that I could learn from) would be appreciated!

P.S. Perhaps this patch idea is a task for Polybrute 12’s FullTouch keybed.

Could the motion record help you achieve this ?

Maybe try this : https://nuage.michaelgoldberg.fr/index.php/s/53Byr4xSoWESo7k

You have to load the preset in Polybrute Connect then send it to your Polybrute.
The Ribbon lets you control the sustain level as long as you press the key. Fully left there is no sustain at all.

Great idea. That would allow me to get the right shape. The drawback is that I’d just have to play each key until the motion record went through the full modulation so that each note had that reverse playback sound. I was hoping that I could do it in a way where I could stay on a note as long as I wanted and then have the volume increase and filter open up right at the very end, but I think that would require a velocity key release modulation source. But the motion record would be a nice plan B. (And it’s such an awesome feature of the synth.)

Thank you! I’m excited to give this patch a try!

The patch is so that when you release the keys the sound comes immediately at its maximum and fades away following the VCA Env Release. If you want to make it come gradually move the Mod Env Release up. You will have to play a while with both Release pots to find your right setting.

By the way (if the patch is what you are looking for) it is only one of different ways to achieve such a sound. It is very interesting to use LFO3 as an envelope in place of Mod Env. You can also modulate the filter output in place of the VCA. Etc.
