MMultiBandDelay iterative feedback filtering

[elassi]

What I would need is a cutoff that progresses with the repetitions. I.e. first repetition gets filtered at 7kHz, second one at 5kHz, third one at 3kHz, and so forth. That way you would hear a more uniform darkening of the subsequent repetitions. Highs would be cut subsequently down.

I guess that will be difficult to program though

You're probably thinking in a too complicate mode.

Why not dim the cutoff down/up according to the delay time? With a falling or rising curve? You can achieve that already. Have a look into the modulator's pane.

For a start:

And probably awfully CPU intensive.

Thinking about it i wonder if a less steep filter would be the right thing, set it to a fairly low frequency but the first echo won't be dampened all that much as it just doesn't cut that steep. Than the next repetition will be cut some more and the next one even more etc. The cutoff frequency would probably be set somewhat lower than the lowest you'd want to hear. This should be simple math, if we're dealing with for instance a 6 db filter.. ..arhm, I'm to tired to think about it now and for some reason I suck at thinking in therms of db anyway (perhaps because other things seemed more fun when I initially started out learning stuff) but I hope I'm on the right track here...

Yes I guess a very shallow filter slope would do the trick. 6db per octave is already too much. It should be about 1db per octave I guess, or even less? At least that would do the trick and you don't need additional programming. Just a special filter type.

@elassi: I guess your suggestion won't work, because you are modifying the cutoff parameter that affects ALL feedback, while feedbacks of different already played notes are at different "filtering states" so to say. You would need an independent modulator for each note played which is of course not possible.

So there is already a filter?

I didn't know it because I didn't had my DAW open today. I searched in the MMultiBandDelay (PDF) documentation for "filter", but to no results...

Yes

Yes, a LP and a HP even with resonance and saturation

Unfortunately they seem to be to steep for what I want to do.

But if you choose for the LFO a waveform with a slow falling curve - for example part of a sine - and a very slow rate (as well as "sync"), it should be possible to get such a light damping effect...

Because the delay should be sync'ed to notes, anyway, otherwise it wouldn't make any sense...

(I should open my DAW but it's too late now, anyway...)

[CableChannel]

No, you cannot sync to notes, you can only sync to bars. That means the delay makes this darkening movement, but all notes at once, not each one to its own timeline.
And if the new bar starts, the filter suddenly jumps open again.

I want each note played to have a delay tail that darkens away. Thats not possible via LFOs.

If delay sync times are the same as LFO sync times, it isn't possible, either

EDIT: Maybe you have to enable "MIDI Reset" in the LFO section?

[Tricky-Loops]

According to the manual, if you DISABLE "sync" at the LFO section and ENABLE "MIDI Reset" instead, it should work with MIDI notes and not only with bars!

Holy crap I missed a whole conversation . Ok, so I'm not really sure how many ideas/questions are there, but for starters...

- Feedback filtering is already in MMultiBandDelay, just set Filter mode to Feedback filter.

- Filtering in modulators - I noticed this one, but I kind of don't know how to understand that . I'd say, use Follower mode and that's a bandpass, but if that was related, that I really don't know .

- Filtering first echo with 7k, second with 5k,... You suggested a pretty good way to do that using the band input gains. I'd personally try using similar approach, but just set the all bands to feedback filter and band starting at 7k would have max frequency 7k, band starting at 5k would have 5k etc...

- Sync to notes - in modulators you can do that by enabling the MIDI reset indeed.

[CableChannel]

OK so I tested Tricky's method. The problem with that in theory is, that there is only one filter, and if you play two notes they would need each one an independent filter. Because otherwise, the first note is played, resets the filter, then the LFO starts moving, then comes the second note, resets the filter again, which applies to the feedback of both notes.

Practically this isn't much of an issue however. The first note's delay is already filtered to a pretty dark signal, when the filter opens on the second note, it does not really do much harm. The filter of the first note does not really move down smoothly, but you won't hear much of it.

Anyway here is a test:

A little more aggressive resonance would be nice, but it is ok.

Vojtech, how about a modular effect system where you can connect effects any way you want, build loops etc

The method using the band, Vojtech do you mean I should create one band for each delay tap so to speak? Wheew I guess that would also get CPU intensive.

[MeldaProduction]

CableChannel, well, you are talking about MXXX. Damn, I need to put it up in the priority chain... but first MBassador and AAX.

And yes, I meant one band for each tap, was just brainstorming . When I'm thinking about it, it actually wouldn't do the thing anyway .

[CableChannel]

CableChannel, well, you are talking about MXXX.

Something to look forward to

Can I sign up as beta tester?

[CableChannel]

PS: Maybe you should write MCloner first so that you can multiply your working power

[MeldaProduction]

Well, not for beta testing, but if you are good in designing presets...

MCloner - why didn't I think of that before???? But what if my copies wouldn't stand each other!
