Unit: BANDS (please help me understand them?)

Can anyone help me understand the Bands units??

Two Bands … Six Bands > Multi-band versions of the Custom Unit which can be used for parallel processing. The unit’s input is routed to each band untouched. Each band is mixed to unity to produce the unit’s output.

So are they basically a dry mult? Someone please offer an example of how bands can be implemented in a multi fx manner perhaps?


Place a multi-band unit on a sample, then select one of the bands. On that selection you can insert a unit, choose the flanger. Go up a level and choose another band and insert a delay. Now those two bands each have different effects.


Does this help?

So the idea was to run all bands through a single summing unit?

Hmm ok, so placing the fx separately in the Bands channels offers VCA fader control over each fx?? Pretty nifty !!!

I’m not sure I understand your question…

The idea is to allow you to split a stream of audio into multiple bands, treat them individually and then combine again. The prototypical example is to use a 2-band, place a LPF in one band and an HPF in the other band (*). Now you have split your signal into high and low bands to which you can apply separate effects.

(*) Joe’s bandpass filters would be very useful here too.

Your description of the 2-band unit is what I was trying to explain to the OP, but your chart shows the bands going into a single summing unit, or so it looks to me. So it seemed to suggest that each band did not feed into an individual unit but into a common summed unit before hitting output. Sorry for the confusion.

The output of each band does feed into a single summing unit though. Perhaps it is not clear that the bands in my picture are chains?

That’s not clear to me that it was meant to depict a chain, I thought it was the specific frequency band.

How about this?

By the way, the bands are not going to be split by frequency unless you actually put filtering units in the beginning of each band.


That I can understand!

I’ve had a lot of fun using bands to create multi-oscillator blocks and complex CV generators… adding custom controls for pitch, sync, etc… and then each waveform generator is in a different band. Visually, it’s nice :slight_smile:


May I suggest that the word « band » is a bit confusing as it is often reffering to frequency bands ?
What would you think of “rack” ?

So Bands are simply a way to run units in parallel, rather than series, without having to use a mixer for each unit?

@odevices Will we be able to edit the title of each Band at some point - or maybe the word Band X is removed once the band is populated (as it covers the view of the units output)?

I agree “Band” might be better as “Rack”… or “Thread”.

I am being cavalier with the term but only because it has the clearest association with the process of splitting a signal, affecting each copy differently and then recombining at the end. Would you not prefer to stretch existing terminology over adopting a more generic term?


That and the averaging operation.


it is very similar to what ableton live refers to as “chains” in the context of instrument, audio effect, midi effect and drum racks.
but here the term “chain” is already taken.

Yes, I admit my mind is under Ableton Live’s influence.

I can tell you the first thing I did was take a sample Player, split it into 3 bands, place the eq on each band to split frequencies, then sample and holds after each band to create a multi band sample rate reducer effect. Really awesome.
I like the name bands as imho it’s quite clear what it does. Ken Flux Pierce on Instagram: "I've been wanting something that does this for so long. Finally with the er301 I was able to build it myself! Multiband samplerate reduction with time stretching and slicing all voltage controlled. . . #FLUXWITHIT #modbap #eurorack #modular #synths #producershit #producerlife #beatmaking #sounddesign #diyrecording #modularsynth #samplers"


Being able to rename the bands would be super helpful, as then the bands are labeled for whatever process is churning away within.

For example, In my multi-band oscillator custom unit, I could literally have the OSC1, OSC2, NOISE labels over the scopes.
