>3-Band Multiband Send

What the title/subtitle says: greater-than-3-band multiband send, and send tracks which are so obviously related to the same sound ought to take up less horizontal space, the more bands you break up the multiband send into.

Also: a “add N send channels and route this multiband send into them” button
Also: a way to throw down the same effects onto all those bands so I can say goodbye Stardust VST. Or I could Hydra it, that would be OK ;)

We decided to go “compromise” between usability and cpu usage, so we ended up in 3 bands, cause 3 is the magic number here, and enough for a lot of tasks. If you need more you can chain multiple multiband for a huge 9 bands send device !

How? I only have this image to go by:

But this shows as only the dividing points being available to be set. So the Multiband send always covers the entires 20kHz bandwidth, so you can’t use one for only 20Hz-400Hz, another from 400Hz-3kHz, and last from 3kHz-20kHz (random values for example.) Guess you could add your own Filters to the Sends to try and cut out unwanted frequencies but then again we are moving into quite a hack bodge job.

Nah, easy and fast. And here you can still see how the device renaming could come handy.

  1. create 4 send tracks
  2. paste this as device chain in a track
  3. go to mixer view

Had another hard drive failure so can’t do any playing about in Renoise itself, hence why I stated I only have that image to go by, so afraid I can’t open and paste in that DSP chain to see what you’ve done…

Cascading of the Multiband spilt/sends may be a better idea that using filters to try and top and tail though…

Nice trick, thanks.

But I also recommend more bands because sooner or later the need and demand for more bands emerges and now that we have it in beta version, why not enhance it to make it more efficient. CPU usage-wise, we could have for example 2 dsps, a 3 band and a 5 band multiband send to choose from…

Slightly off topic academic question: What sort of filter type do the splits operate on? It feels, to my ears, like a 24dB slope. Or is it something else? Just would like to know for nerdy reasons. ;)

i’m not sure about adding more bands, as this add also more phase differences in the bands that will be processed by several filters (thus creating phasing artefacts). not mentioning a general complexity trying to stick all those bands parameters in the gui layout. also there will be someone one day that needs seven bands, and we will never finish here.

the 3 bands are created using two 4th order Linkwitz-Riley filters (24 dB/oct) with zero phase difference between bands and original material.

Thanks mate! You satisfy the nerd in me. ;)

After playing with the 3-bander, yes, it is quite good for a lot of tasks. Those of us crankin out hardstyle tracks I suspect will be tempted to leave Ohmicide VST by the wayside.

I just realised, with the four-bander kRAkEn/gORe provided at least, that there’s an audible notch-reject sort of effect happening at the band boundaries.

I would have expected that “merely” pushing audio through a multiband send, from a usability point-of-view, should not alter the audio whatsoever.

Yes, stacking filters in serial always produce phase differences when mixed with the unprocessed input signal, that results in the notch like effect you are listening. For that I decided to go with full 3 bands - 2 stacked L/R filters to minimize phase problems.

i don’t understand shit of all this but its pretty cool that people are thinking about this.

Now i want to see what kind of multiband effects you can build with this. Start experimenting with one gate for each band, and change the transients of the kick in a drum loop, while shortening the charleston tail in realtime… fresh new feelings for the same drumloop!

i think you make a valid point here. people see the new features and come up with requests almost immediately, while imo the most awesome creations are made a while after the effects are available. for example, how long have the dc offset device, keytracker and ringmod been available before dblue made his native synth? people should take some time, be happy with what they have.
