Mutable Instruments Streams
Streams is a multi-purpose dual dynamics module featuring an analogue VCFA, each with manual and CV control and continuously variable exponential to linear curve response. The module also features a flexible Excite input governed by a DSP algorithm, rendering it capable of several versatile modes of operation:
AD envelope generator, vactoral curve emulator (complete with an alternative mode that allows one to ping the vactoral via the Excite input), harmonic and amplitude follower, and as a compressor/limiter.
Additionally, Streams is DC coupled and works exceptionally well when processing CV.
