Hi everyone,

My name is Andrew and I am co-founder of Hullabaloo. We are moving into the beta stage of our first plugin, Parallel Universe, and could use your ears and your help!

TLDR version: Its a wrapper plugin effect rack that brings inter-plugin communication support to your favourite 3rd party plugins. We built this as a way to improve some of the quality of life things we thought were a hassle to deal with in a DAW.

A quick rundown of some of the key features:
  • Navigation: Open plugins across tracks without leaving your currently open plugin window.
    As an example, you could open your drum bus compressor from the interface of your guitar EQ, so you don't have to scroll through your DAW tracks over and over to find specific plugins
  • Mix Auditions: Switch to alternate signal processing settings or chains across your whole session with 1 click
    You can set up different versions of the same mix, or entirely different styles of creative effects with completely different plugins, and swap between them instantly across all your tracks. So now you don't always have to Save As and make a new session file, or bounce alternate session files, to hear different versions.
  • Blind A/B/C/D: Remove visual feedback and perception bias with loudness matched blind A/B comparisons, which extends to blind A/B of full signal chains and even mixes
    For the individual plugin settings blind A/B, you can A/B the bypassed signal against 4 different settings. At the signal chain level, you can blind A/B full signal chains across all your tracks from 1 window.
And, currently in the Alpha stage but looking to have it join the Beta soon, we are building a Parallel Universe Remote Control. This means any 3rd party effect can be controlled from a different device. And the neat thing about our remote control is that access to the plugin is not limited to one person, meaning collaborators can try different creative signal processing concurrently.

We'd love to have you all download our free beta trial and give us some feedback on what we could do better. For a little preview video on the plugin and to download the beta, head over to our website:

Anybody who signs up to the beta will also be given a discount code at launch.

Thanks for your time!

Sorry about that! We'll have a look through, but it looks like some sign up are coming in so please drop us an email at support@hullabaloo.audio and we'd be happy to sort you ASAP if its giving you trouble.

Edit: Found the culprit and its been fixed. Apologies! Still feel free to email if there is any further trouble.

PS be sure and check spam folders if the email doesn't hit your inbox within a few minutes of sign up :)

looks like a useful concept...tangible workflow enhancement...a true utility plugin...but it's like system engineering ROI lol...you gotta put more overhead in the setup upfront,...to receive dividends on the back end
Music had a one night stand with sound design.....And the condom broke

Several things that I am interested in inside of one plugin.
Didn't demo it yet but if it does what I expect after watching the demo it is really interesting to me.
Let's see if it keeps up with my expectations, workflow, stability, etc.

Thanks for the kind words, and yeah the plugin can get pretty deep if you want it to!

I'll be adding a Walkthrough tutorial before long and will be sure and come here to share. There's no requirement to build out full mixes upfront, though. You can add as you go when you want to experiment with a different tone/sound on specific tracks or groups of tracks.

As we're looking to expand the remote control capabilities, we also wanted to be sure there was enough flexibility for a collaborative system, so wanted a way for multiple users to overlay different mixes within the same environment non-destructively.

Excited to hear what you think when you get a chance to demo it!

We're really trying to prioritise stability as we understand using something like this, particularly as it offers some form of version control, is crucial for users.

We did decide to make the signal-chain swapping pretty open-ended for users. We've tested it swapping upwards of 60 plugins in total across a session mid-audio stream on one button press and it's been fairly seamless, but obviously will depend on each user's CPU limitations and the plugins they are enabling. Curious to hear what limits you run up against though!

It seems to me that there should be a mode to show the knobs for all plugins and instances together. Personally, I wouldn't use this to build complex chains, but would instead control the EQ's on different channels simultaneously.

Thanks so much! This is great feedback, we're going to see what we can to figure out something along these lines.

We were planning on surfacing macro controls in the remote, but were aware that it would end up making the remote arguably more powerful than the plugin...! Something like this seems sensible.
