plts - a very versatile oscillator based on Mutable Instrument Plaits

Change Log

1.0.0 Initial Release

Developer: TheTechnobear

I develop these plugins for free, please consider supporting my efforts with a donation.

Download: (2.1 MB)

important note: this requires the LATEST SSP firmware ( > 26 Aug 2020)

Short demo

Uses 8 Plts, 2 Pmix , 1 Clds : around 50% of cpu (!)


copy the plugins/*.so to sdcard /plugins

Optional Installation

you may want to copy and rename the demo presets contained in /presets
you may now remove /plugins.preset folder on SSP sdcard as its no longer used

General Usage

The best source of information about this module is the Mutable Instruments Plaits manual

This document is based on the LATEST version of the plugin


I only recommend using at 48 khz sample rate, as this is how the Plaits code is designed.
Using at other sample rates may lead to incorrect pitch, and possible other oddities.
( the only solution would be downsample/upsampling but this is sub-optimal on a platform such as the SSP)

FM / Morph / Timbre modulations are not working !?

This is a ā€˜plaitsā€™ feature - theres built in ā€˜attenuvertersā€™, which I default to zero (see next tip!),
you should turn these positive or negative to apply some modulation.
Why? we already have attenuation in the SSPā€¦ indeed but for compatibility with ā€˜internal modulationā€™ we need, see below.

when I trig plaits I get some weird modulation, why?

When the FM, Morph and Timbre CV inputs are not connected, Plaits has a built in envelope modulation for these parameters,
this can be positive or negative (0 = no modulation).
This is particular useful for percussive sounds, e.g. you can do a kick drums pitch env just by altering the FM modulation amount.
