Faust Effect Delay Time Sync

HISEnberg

@DabDab A couple of things I try in these occasions is resetting the stepsize on the Faust scriptnode, using a smooth node to control the Faust node, or resetting the step size in the Faust code and "rebuilding parameters for Faust file" and refresh the node.

Also it seems to me that the issue you might be having is that the dm.greyhole_demo is in seconds whereas you need it in milliseconds to control with the tempo_sync? You can convert this using a cable_expr and multiplying by 0.001, then connecting to a minmax, then to the faust node. I did this and it works for me. Conversely, you could try writing your own version of the faust code from the reverbs.lib where you can set the scaling size: https://faustlibraries.grame.fr/libs/reverbs/

Also the license on that code is GPL2, just fyi.

@HISEnberg this is what I was looking for...some math!

RE: the license comment, I just find that the Faust effects are cool, just hard to use. I plan on porting some and just putting them in VST format for free for people to fool around with. Not really interested in profiting from and/or selling them.

cable_expr

Can you please correct my script nodes? I am unable connect with tempo sync.
What I am doing wrong ?

@Hisenberb the absolute lad!!! thank you

DabDab

@Hisenberb Excellent. Thank you dear. :beaming_face_with_smiling_eyes:

DabDab

@HISEnberg Unfortunately not working. I have connected what you have shown. But Faust Time is not being changed.

HISEnberg

@DabDab Strange it seems to be something to do with your cable_expr node, did you press "enter" after writing "input*0.001"? Will the minmax node control the faust delay?

DabDab

@HISEnberg Yes.. I pressed Enter after the code.

Cable_expr value is not controlling minmax value. But Minimum value is controlling faust node DelayTime correctly (upto 1.0 value).

I don't know what am I doing wrong !!

FatMitchell

@DabDab try putting the min max to 1-1.45

DabDab

@FatMitchell ok, I tried but the problem is tempo sync is not controlling the faust delay time.

HISEnberg

@DabDab Did you change the minimum and maximum values of the cable_expr node? I typically don't do this. Let me know if this works for ya, it works fine for me:

@HISEnberg Thank you so very much.
Your snippet is working fine. I have also got the step what I was missing.

jeffd

@DabDab

Ive tried this same setup in my project,
but when i compile it to a dll network and use as a hardcoded masterfx...
I get a predelay sound, before the delay sound. Hard to explain.

Its as if there is another dry signal being thrown in the path before the effect.

did you have this problem after you compiled it?

I have tried every routing matrix path i can think of at this point to see if that was the problem but to no avail

DabDab

@jeffd I was having same problem. I thought may be I am missing something. Didn't find any workaround.

jeffd

@DabDab
oh damn,
hmmm.. yeah i cant figure it out. maybe has something to do when faust effects are compiled in the network. it works fine as a scriptfx.

I need a decent sounding delay..guess I will look into max/msp rnbo.

Just use the nodes in scriptNode itself - including the fixed delay and send and receive - you can build any delay you want...

jeffd

@Lindon
I did that, and with the smoothing nodes...
but i still couldnt get anything to sound good.
perhaps i should look at it again.

Lindon

@jeffd smoothing? you want to change delay time in real time? No delay is going to let you do that without artifacts.

jeffd

@Lindon
right...yeah i wanted more of an analog style sounding delay.
or less digital sounding delay with less artifacts.

the faust greyhole sounds nice, its more of a reverb, but i could get it to sound like a nice, modulated analog style delay.

It is tonly part of the instrument i am buiding, and honestly, I never use delays that come loaded with vst instruments but it is nice to have.
