Mutable Instruments Streams Dual Dynamics Gate Eurorack Module
Mutable Instruments Streams provides two channels of extremely flexible signal dynamics manipulation in a 12HP Eurorack module.
- Powerful and flexible dynamics processing module
- Dual independent channels
- Multi-purpose EXCITE input per channel
- DC-coupled inputs
- 12 HP Eurorack module
Each channel consists of an analogue voltage-controlled filter and amplifier (VCFA). The response curve of the amplifier section is continuously variable from exponential to linear. The amplifier gain is directly controllable from a CV input, through an attenuator. But what makes Streams truly unique is the multi-purpose EXCITE input. The signal routed to this input is analyzed by a micro-controller and translated into internal control voltages for the VCFA, turning Streams into a very versatile signal contouring tool:

The EXCITE input can work as a trigger input, triggering an internal AD or AR envelope routed to the gain and the filter cutoff (in variable amount). With only 6-HP of space, you can shape an oscillator or noise source into a full-bodied sound.
Vactrol Curve Generator
The EXCITE input is processed by a digital model of a resistive opto-isolator (Vactrol), controlling the gain and the filter cutoff (in variable amount). The digital emulation allows the modification of properties of opto-isolators – such as response time – which are otherwise difficult to control. The virtual vactrol response can be either optimised for processing CVs, or triggers (for 'plucked' sounds).
Amplitude And Frequency Content Follower
The envelope and cutoff of the EXCITE signal is measured, and applied to the signal on the VCFA input.
Streams' VCF is disabled, and the VCA is used to control the dynamics of the input signal. An intuitive control scheme allows the compressor to be used either for peak reduction/limiting operation or for boosting signal levels with soft-limiting. The EXCITE input can be used as a sidechain.
