slowfield audio / beta 1.0

the sandwich

bread 1 > filling > bread 2

A three-stage creative audio effect built around a simple idea: shape the sound before, transform it in the middle, then decide what happens on the way out.

Beta software — currently macOS only. This is an unfinished test build uploaded so users can find bugs, test the workflow and help us develop The Sandwich further before release.

02

signal flow

one idea. three stages.

The Sandwich is designed to be understood from left to right. Bread 1 shapes the incoming signal, the Filling transforms it, and Bread 2 decides how the sound leaves the chain.

01 / prepare

bread 1

Choose a bread effect and shape it with three context-sensitive controls before the centre stage.

03 / finish

bread 2

Use the same effect type as Bread 1, then Link, Mirror or Free the parameter behaviour.

relationship controls

link. mirror. free.

These controls are central to the Sandwich concept because they determine how the two outer stages interact.

LinkBread 2 follows Bread 1 exactly for symmetrical processing around the Filling.
MirrorBread 2 becomes complementary: controls 1 and 2 invert while control 3 keeps the same amount.
FreeBoth outer stages become independent, allowing different settings before and after the Filling.
Copy + SwapMove stored settings between the two bread stages and switch directly into Free mode.
global controls

colour, balance, protect.

Toast adds saturation and colour. Bite is the global dry/wet control. Final output trim and automatic output protection sit after the main effect chain.

Chef’s ChoiceRandomises the recipe when you want the plugin to surprise you.

Input + output metersStereo metering with peak indication for keeping the chain under control.
effect palette

familiar ingredients. stranger combinations.

The outer Bread stages share one effect type, while the centre Filling can use its own independent four-control process.

three recipes to try first.

Start with something useful, then reshape the sandwich from there.

ambient wash

Bread: filter · Mode: mirror · Filling: reverb or granular · Toast low · Bite 40–60%

textured delay

Bread: drive · Mode: link · Filling: delay · Toast medium · Bite 30–50%

experimental motion

Bread: orbit or ring mod · Mode: free · Filling: smear or resonator · Bite 50–75%

why this beta exists

we need real sessions, not staged demos.

The Sandwich is deliberately being shared before release so users can find problems that only appear in different DAWs, projects and workflows.

We especially want to know whether the Link / Mirror / Free logic is clear, whether gain changes feel controlled and which effect combinations are actually useful in music.

feedback that helps

tell us what happened.

DAW + macOSTell us the host and macOS version you were testing.
what were you doing?Which Bread effect, Filling and relationship mode were active?
can you repeat it?Give us the shortest steps that make the problem happen again.
what should stay?Happy accidents, presets and combinations are useful feedback too.
open beta

download it. build something. tell us what needs work.

No application form. The current test round is Mac only and intended for users who are comfortable trying unfinished software.
