Fluxfi sidechain sampler custom unit

So I have created a nice Lo-Fi sample player in the 301 where I simply handle sample rate reduction via a S&H+ oscillator combo into a Grid quantizer, sounds great BUT got me wondering. since there is only 256 levels this should mean the grid quantizer at max setting should be 8 bit. 4096 would be 12bit yes? is there a way to get more levels into the quantizer? I would love to be able to fully vary from 12 bit (or higher) on down.

update, here it is… its a free download on my site. https://fluxwithit.myshopify.com/products/flux-fi-sc-sampler-for-er-301 I haven’t tested the download link yet and have to leave… so if it doesn’t work just let me know.**


I think that’s right. 256 levels = 8 bit.

If you are running the latest unstable firmware 0.4.11, you can edit the control so that it goes from 0-4096.

If you are running 0.3.x firmware, you can’t edit the control. However, you can make it go beyond the limit you can turn the fader up to by using internal CV.

E.g set the gain on the levels control to 7.5, bias to 256. Then in the subchain insert
offset (offset=1) --> rational vca (num=32) --> rational vca (num=16) will yield 4096 levels on the scale quantizer.

Setting the system setting “Displayed value for unit control readouts” to actual makes it easier to verify the result.


Interesting approach! Are you willing to share it as a custom unit?

Thanks Joe, forgot about editing that control.

Yup will share a few alternate versions of this possibly tonight.


this is great!

I was wondering about this before, didn’t realize extending the max range was as easy as editing the control. Now I’ll have to try that with some of the other units…


hey @Flux302, i am just watching your 301 hangout
(reminds me of your producers hangout, which
i miss soooooooou much!)

and i wanted to add the current state of your ‘early error’ to the user contributed preset page in the wiki

any chance you’ll share that creature here? or is that error too early?:smiley:


I’ll try and get it up tonight along with a couple others. Just been swamped doing “real work” … I’d like to clean up the side chaining tonight then upload it


here it is… its a free download on my site. https://fluxwithit.myshopify.com/products/flux-fi-sc-sampler-for-er-301 I haven’t tested the download link yet and have to leave… so if it doesn’t work just let me know.


nice! gonna try it next days!
what do you mean by “sidechain the audio to the sample rate” ??

Oo I can answer this based on the hangout video. There’s an envelope follower attached to input audio level which can modulate sample rate. So the loudest parts can be crunchier than the quiet parts.



I’m mobile the link above is a video on the module

registration to your website required to check out your custom unit?

Registration? No. Did you go to the link? It’s a free download

ah ok so the email is only for receiving the link?just felt a bit weird because up to now the CU’s were hosted in places where you don’t need to show your email (here or github).

I use my site for a few reasons 1) why not drive more eyes toward my products so if people want to support the services I provide. 2) I don’t have to worry about losing content because someone else packs up their toys and goes home.
3) I kinda forgot that you can host right on here lol. But even so I don’t want to keep up with updating my units in various locations, nor worry about hosting size limitations. I often release large sample packs and I’d like to do the same for the 301.

Either way, nothing nefarious going on I assure you.

so there’s nothing to stop you from posting the CU here, too? :smile:

(you could also post it zipped with a friendly add from fluxwithit that contains
links to your site and products. personally, i don’t like “free” downloads where you have to give an email adress very much…)

Downloaded it yesterday - great work Ken :smiley: thank you.

Re. paying for downloads with personal information:

Since last Black Friday when my email client was pinging every few seconds with thousands of harassment emails, many companies sending more than 5 messages a day trying to make me buy stuff, or ‘letting me know about things’ I have been aggressively unsubscribing from everything I have ever subscribed to. I want my email address back.

Most unsubscribe processes have been good, however 6 months on, for various reasons, I am still battling with some of them.

While I am not saying you would abuse my information, I am afraid email as a marketing channel is 100% dead for me now and I have a very hard time trusting anyone with it as a result of this digital bombardment.

I am working on a system that will let me use a different email address for every company I interact with, so I am in full control. The moment I don’t want to hear from a company any more, I delete the account, or stop it forwarding messages to my main account, and they are left out in the cold permanently.

I think it’s disgusting that I have had to go to these lengths, but this is the way of the modern world. We must fight.

So, my recommendation is to do everything you can to remove the barriers to folk using your ‘free stuff’ or just charge for it and make your 100% compliance with GDPR very clear. Saying something is free when it actually isn’t just makes me not trust you @Flux302. Because of my experiences elsewhere, there is no way I am giving you my personal information for this download, I am pretty certain this isn’t what you want.

Apologies for the side track, but my little rant is over… feel free to do whatever you want, of course, this is just well intentioned advice, as you were :slight_smile:
