This is a creative MIDI converter module with a high-performance MIDI to CV / Gate conversion that can be used in various settings, a 101-step sequencer that inputs in a manner similar to the SH-64, and even a digital oscillator. The output DA converter is 16-bit and can output highly accurate pitch CV.

All settings are done by simple operations by rotating the encoder and clicking. Use it by turning the encoder to select the option you want to set, then turning it again to determine the value or setting for that option.

All settings can be stored in 8 presets. Save and load by pressing and holding the encoder to access the S (AVE) and L (OAD) menus (preset 1 is always loaded after powering on the module).


The explanation of each part is displayed by mouse over  


Yarns has 4 CVs and 4 Gate outputs on its output,Up to 4 voices, 2 voices by chaining 8 YarnsCan be converted. It is possible to perform MIDI → analog conversion with various settings such as 2 voices, 1 voice, 4 trigger modes.

In Yarns, the biggest setting of how to convert MIDI to CV / Gate is "LayoutThis setting is determined by the "LA (YOUT)" option in Yarns (see the knob description for how to set the option). In the layout, how many voices will be on which MIDI channel The MIDI channel is called a "part." A voice is a monophonic melody.

After selecting the LA (YOUT) option, the setting values ​​that can be selected are as follows.
  • 1M: Converts one monophonic sound.
  • 2M: Converts two monophonic sequences. The two are on different MIDI channels.
  • 4M: Converts two monophonic sequences. The two are on different MIDI channels.
  • 2P: A duophonic mode in which one part (MIDI channel) can simultaneously convert up to two sounds.
  • 4P: Quadruphonic layout that converts up to 1 sounds simultaneously in one part (MIDI channel). You will be able to convert 4 chords.
  • 2> 4> / 8>: These are layouts that chain two Yarns with a MIDI cable and output a lot of voices. 2>, 2>, 4> One Yarns each outputs half the number of voices (8).
  • 4T: Quad trigger layout. Each of the four parts outputs a trigger signal in response to the on / off of only one scale.

For each layout, the output signal will look like the image below.

"Modulation CV" outputs the modulation wheel, and "Assignable CV" outputs the MIDI signal values ​​that the user can assign.

See the "Options" section below for layout and output settings.

Clock and Tempo

The tempo can be set by selecting the optional TE (MPO).The tempo is in BPM units and only the last two digits are displayed.The numbers will flash at that tempo when set. If you turn the encoder to the left of 2 BPM, EX (TERNAL) will be displayed and you can synchronize with the external MIDI clock.The internal clock can swing. Please set from the SW (ING) option. In the 40M, 1M, 2P, 2>, 2>, 4T layout, the clock can be output, but it is also possible to output the divided clock with respect to the MIDI clock. Set with the O / (OUTPUT CLOCK DIV) option. please.It is also possible to set the tempo itself by dividing the clock. Set with the I / (INPUT CLOCK DIV) option. Even with a 4M / 4P / 4> layout, it is possible to replace the gate 8/3 output with a clock output. Set from the C> (CLOCK OUTPUT) option.


In Yarns, when you enter a code for each part, it will be decomposed into arpeggios and played. Access the arpeggio settings from the options below. In the setting items, the three parameters "EUCLIDEAN ~" are the three parameters that are given to the algorithm when "Euclidean algorithm" is selected for arpeggio rhythm generation. Pattern is determined).
  • C / (CLOCK DIV): Arpeggio clock setting.
  • G- (GATE LENGTH): Arpeggio gate length setting.
  • AR (ARP RANGE): Sets the arpeggio range in octave units.When zero, arpeggio is disabled.
  • AD (ARP DIRECTION): UP, DN (down), UD (up & down) RA (NDOM) mode, PL (AYED) is the arpeggio mode in the order in which they are pressed, and CH (ORD) is the gated chord effect mode.
  • AP (ARP PATTERN): Sets the arpeggio rhythm pattern. If the lower E- is not 0, this setting is invalid and the Euclidean algorithm rhythm pattern is used.
  • E- (EUCLIDEAN LENGTH): Sets the rhythm pattern loop length using the Euclidean algorithm. When 0, the Euclidean algorithm is disabled.
  • EF (EUCLIDEAN FILL): Use the Euclidean algorithm to set the number of "ON" rhythm patterns.
  • ER (EUCLIDEAN ROTATE): Set the start position of the rhythm pattern using the Euclidean algorithm.


By setting the OS (CILLATOR) option to a waveform other than OFF, the oscillator built into Yarns will be output. The output destination is as follows.
  • CV1 in 4M layout
  • CV2 and CV2 in 3M or 4P layout
  • CV4, CV4, CV1, CV2 in 3M or 4P layout


Each part also functions as a 64-step monophonic sequencer. The input method is the method found on the SH-1 etc. by pressing one button on the connected MIDI keyboard or Yarns at each step. Press the REC button to start input. For layouts with multiple parts such as 101M and 2M, you can select the part to record here. To end the input, press the REC button again.

For input, enter one of the following for each step.
  • Note: Input by pressing the MIDI keyboard. Velocity is also recorded. AlsoPress down while tilting the pitch bend to enter a slide.
  • Tie: Press the START / STOP button to enter the tie where the previous sound continues to grow.
  • Rest: Press the TAP button to input a rest (REST).
You can also return to the previous step by turning the encoder during input. Also, by pressing the encoder, you can select the value of the note etc. to be input, so you can program the sequencer without a keyboard.

When input is complete, you can start and stop the sequence with the START / STOP button. In addition, the sequence will synchronize to the external MIDI clock in the mode that synchronizes to the external clock. If you enter a MIDI note during playback, the sequence will be transposed. If you press the REC button during playback, the sequence will remain the same, but if you input a MIDI note, the step at the time of playback of the sequence will be replaced with that MIDI note.

The sequencer cannot be run at the same time as the arpeggio. Please note that when you press START / STOP or when Yarns receives a MIDI start message, the sequencer will start and the arpeggio will stop.


Layout and MIDI related options

  • LA (YOUT): Select a layout.
  • PA (RT): When selecting a layout with multiple parts, you can set the active part to be set.
  • CH (ANNEL): Receive MIDI channel setting.
  • NO (TE): Set a note for each voice in a 4T layout that creates 4 triggers with different MIDI notes.
  • >> (OUTPUT MIDI MODE): MIDI OUT will be OFF / THRU / arpeggiator (or sequencer) output depending on the setting.Also used in 2>, 4>, 8> for Yarns chains.
  • VO (ICING): Settings for handling multiple voices in one part, such as 2P, 4P, 2>, 4>, 8>.
    • PO (LY) Swap voices like a normal polyphonic synth.
    • CY (CLIC) Notes are circulated through the voices and assigned. .
    • RA (NDOM) Notes will be randomly assigned to voices.
    • VE (LOCITY) Notes will be assigned in ascending order of velocity.
  • NP (NOTE PRIORITY): Priority of notes when some keys are pressed. This can only be set in a monophonic layout, where one voice is assigned to one part. LO (W) est and HI (GH) est give priority to low keys and high keys. LA (TEST) gives priority to the most recently pressed key.

CV, gate and trigger related options

  • LG (LEGATO): Legato setting. Valid for 1M, 2M, 4M layouts. When set to ON, signals are output so that overlapping notes become legato, and trigger signals are not output at the start of connected MIDI notes.
  • PO (RTAMENTO): Adjusts the portamento (time-based) speed.
  • BR (BEND RANGE): Sets the pitch bend range in semitone steps.
  • VR (VIBRATO RANGE): Set the Vibrato range (Modulation Wheel range).
  • VS (VIBRATO SPEED): Set the speed of Vibrato.
  • T- (TRIGGER DURATION): Adjusts the length of the trigger pulse.
  • T * (TRIGGER SCALING): This setting is valid only for 4T and determines how much the strength of the trigger signal will respond to velocity.
  • T / | (TRIGGER WAVESHAPE): Outputs the waveform of the trigger pulse in various forms. Usually SQ.
  • CV (AUX CV OUT): In a layout that has an "Assignable CV" output, you can set what is assigned to that output. Choose from AT (AFTERTOUCH), BR (EATH) controller (MIDI CC # 2), PE (DAL) (MIDI CC # 4), and LF (O) where you can set strength and speed with Modulation Wheel and Vibrato Speed ​​options. .
