Small Delay Using Send Device Causes Flanging

Help, Support & Bugs
1

Hi everyone
Hopefully this hasn’t already been covered in another topic.

I read about parallel compression recently and was trying it on some kick drums. For anyone that hasn’t heard about it, the trick is to create a parallel sub-mix with a compressor running at a high ratio and low attack. Adds body (RMS, power) to your sounds without affecting the peaks so much, or taking away from the dynamics, like heavy compression always does. Run light compression on the first track, then parallel heavy compression on your submix, then mix the two using your post gain levels.

I noticed when routing the signal (as the first device in the FX chain for that channel) that there is a small delay sending audio over to the Send channel where the parallel compressor is. This is enough to cause a very noticeable flange. To my understanding, internal signal routing should be almost instantaneous.

Taktik or others, is there anything that could be done to speed up signal routing so that the flange does not happen?

thanks
James

PDC issue.

Not yet fixed in Renoise.

Incredibley annoying, I know.

This means that the Parallel Compression technique you are using is not possible in Renoise yet using the send device (again, pretty ridiculous…)

A work around would be to duplicate the drums tracks you wish to Parallel compress, and do it manually.

A pretty poor workaround, and one which could send the CPU mental if you have a lot of processing on the drums to start with, but it will work.

Basically, we need PDC as soon as possible!

yes this really should be sorted ASAP

If this issue didn’t exist, chances are we’d have proper routing too :P

I had a similar problem using sidekickv3 on Renoise 1.9.0 and onwards.

With support for multiple cores a sideeffect was that sidekick added a delay of 256 samples, which made some of my productions sound sluggish. However, the workaround (besides staying in Renoise 1.8.0) is to delay the rest of the channels to the same amount. I prefer Voxengo SampleDelay for doing this. I often do this setup:

  • Add one of the sidekicks to S01 (sendtrack), and add SampleDelay (set to 256 samples) to S02.

  • On all channels I add a send device-routed to either S01 or S02 depending on what I want to do. I can also put a send device routed to S01 with “Keep Source”-mode on, followed by a send device routed to S02, to be able to mix between how much signal I want to send to respective sendchannel.

A bit cumbersome, but it works.
