Yarns is a MIDI interface providing up to 4 channels of CV/Gate conversion, and providing some of the MIDI message processing features of Mutable Instrumentsﾒ MIDIpal, including arpeggiator, euclidean sequencer, and a SH-101 inspired step sequencer. Yarns provides 4 CV outputs and 4 Gate/trigger outputs, which can be assigned to up to 4 voices. In single voice mode, note, velocity, modulation and aftertouch (or other CC) CV are produced, along with a gate, a trigger, and a clock/reset output. In two voices mode, two channel of note, modulation or aftertouch CV are produced, along with two gates, and clock/reset outputs. Finally, in four voices mode, four pairs of CV/Gate outputs are provided. The 2 and 4-voice modes are available both in a ﾓpolyphonicﾔ and ﾓmultitimbralﾔ flavour. The former receives chords from one single MIDI channel and dispatches them to the voices; while the later provides independent monophonic parts ﾖ which can be addressed to different MIDI channels, keyboard ranges, or even velocity levels. Various note priority modes (low, high, last) and polyphonic allocation schemes (voice-stealing, random, cyclic) allows you to fine-tune the CV/Gate conversion to your playing style. Each voice has a built-in digital LFO to interpret modulation wheel messages as a vibrato; can respond to pitch-bend messages; or can be smoothed with a glide/portamento control ﾖ no need for a dedicated module and patches to get the right response from a MIDI keyboard! Each part can generate sequences either through an arpeggiator/euclidean sequencer combo; or with a SH-101 style sequencer with step-by-step recording, storing up to 64 notes. The module can sync to an external MIDI clock, and generate a clock/reset output at any subdivisions of the MIDI clock. Other unique features include support for microtunings (either through standard MIDI messages or from a selection of historical tunings or indian ragas), just intonation, and an audio output mode which can transform one, two, or four of the CV outputs into simple digital oscillators.
