A4 Feature Requests

I’ve still got one though.

I’m not fucking crazy…

And the AK went to a good home, to be fair.

Yeah, selling that was dumb.

Fucking mint it was too…

I think that we miss (at least) a shimmer reverb. Also it would be cool to have an additional delay slot and a “degrade” effect (it’s S&H processing an audio stream). These things are basic for many synths in last ten years.

New A4 owner here, maybe got four hours on the thing - but this talk of FX has me intrigued.

What about pan most of your tracks to one side, pan the one to treat to the other side, (assuming you’re not a lucky duck with a MKII with individual outs) and run the out back to an input. Then make that input come in as an oscillator I out on a track and do all the funky stuff with it you can there…

I think you do.

I couldn’t be happier that it doesn’t have one.

What would an audio stream be in the context of the A4?

Could you not just use the random LFO?

Are you sure about that? Explain more?
Or are you talking about ‘down sampling’ where you clock a S&H circuit with an audio rate source.
As far as I know this can’t be done on most fixed architecture synths since their S&H is really just a random LFO, not a true Sample and hold circuit.

Certainly in the case of Elektrons, they have a random LFO. Random is not sample and hold.

Really?

I can’t say I have any real feature requests for A4 as it stands. The machine is so densely packed with features that it’s almost “too much” as-is. But on the topic of FX, if we ever see a newer iteration of the Analog Four, I’d love to have some insert effects - being able to tweak some delays per track would be nice. Of course, that’s in addition to the FX track and the classic send effects.

And no, I don’t need or want a shimmer reverb. Maybe a stereo compressor would be nice.

There is a sample and hold on the A4, but it’s not a modulation source, it’s used to tune the noise on oscillator 1.

Yeah, I mean the downsampling effect. It’s a pretty basic digital effect.
I’ve couldn’t remind it’s “brand” name in that time so I’ve described it like it was produced in the analog way :slight_smile:

Well if you’re talking about digital sample rate reduction, that’s something else entirely, and not something the A4 would do… it being an analogue synth and all.

Analog Sample and Hold is the same(ish?) thing though, but would of course require hardware for it which isn’t going to happen.

That said it’s possible to get stuff that sounds like sample rate reduction to happen on A4… If only I could remember how. Pretty sure I’ve seen demos shared around here somewhere.

The ring mod can sound a lot like sample rate reduction

It has digital effects actually :wink:

there is some trick about audio-rate modulation (by square wave AFAIK) to the cutoff of the filter… I’ve did that on Beh Neutron but didn’t tried here. But… it gives not a reduction effect but something closer to a “talkbox”.
I guess that’s the ballpark you’re meaning.
Of course analog samplerate reduction can’t be done in the current hardware. I’ve meant only digital efx from the start.

Yeah, but what are you looking to reduce the sample rate of?

Best place to use SRR is pre-filter on the oscillators, which is obviously not possible on an analogue synth.

Adding it as a send effect seems a bit shit, it’s not really something people tend to use as a send effect.

Curious how many other analogue synths have SRR or other sorts of digital down sampling effects, cos I’ve never come across any…

P12 can do it, but has digital Oscillators.

Yeah, the Dave Smith stuff from that era is awesome for stuff like that.

Best implementation of digital oscillators ever in the Pro 2, 12 and evolvers.

A4 has the digital “end”. So it’s a very simple task to program the SRR effect that will be working in some positions of a sequence and will be completely “wet” if you want to (usually it’s like that sure).
Also it can be programmed not as a send effect. A4 firmware could be programmed to process digital efx in serial and parallel. I’m pretty much sure there is enough CPU power for this. We have just four(!) voices, not so much to process here.
SRR is a very low CPU consumption effect. I’ve wrote tracks using a Pentium-3 PC in 98-200* years and I remember how much is the fish :smiley: You don’t need anything like PolyBLEPs here (that is known to fix aliasing for oscillators). I’ve done few VST “synths” using Synth Edit and (previously) did made some good working VST fx using Sync Modular.
P.S. Minifreak, some others ))

Audio path is all analogue, except for the send fx and the conversion through the USB to overbridge.

The send fx are already set up in parallel, with the ability to mix them into each other’s paths to a certain degree, but they are and can only be send effects without changing the actual circuitry.

Unless you put it on the digital output after the A/D conversion, but then it’ll only be available on the output of each voice and only if you use overbridge. Still no way of getting it where it’ll actually be of use, ie. after the oscillators, but before the filter.
