6HP Yarns. New 1.2 Revision
mBrane is a 4 channel midi to CV interface based on opensource Yarns. The device includes a 1.5m 3.5mm TRS to Midi male cable (Type B). This is the brand new Rev1.1 of the device which now features PSImidi which allows ANY type of TRS midi cable to be used on the input. Type A or B, male or female, all will work.
Running firmware 1.5
Multichannel MIDI to CV/Gate conversion
Yarns is a MIDI interface providing up to 4 channels of very accurate CV/Gate conversion, 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 channels 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.
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 – no need for a dedicated module and patches to get the right response from a MIDI keyboard!
Monophonic and polyphonic
The 2 and 4-voice modes are available both in a “polyphonic” and “multitimbral” flavour. The former receives chords from one single MIDI channel and dispatches them to the voices; while the later provides independent monophonic parts – 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.
With sequencing and note transformation…
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.
… and even more advanced features
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.
