MIDI/voice

By plugging a USB MIDI device into the Ansible Eurorack module, you can access various MIDI-to-CV tools. These tools are available with a standalone Ansible, as well as an Ansible paired with Teletype through dedicated Teletype commands.

The mode LED will show orange when running.

Interface

  • Key 1: Panic (clear all TR/CV)
  • In 1: Panic

  • Key 2: Change allocation style
  • In 2: (nothing currently)

Allocation style 1: POLY

CV/TR output pitch and gate respectively for incoming MIDI notes. CV/TR pairs rotated per MIDI note as a shift register, allowing polyphonic voice mapping.

MIDI sustain and +/- 1 octave pitch bend supported.

Allocation style 2: MONO

One voice, monophonic. With extra parameter mappings:

CV 1: Pitch
CV 2: Velocity
CV 3: Aftertouch/channel pressure
CV 4: Mod
TR 1: Gate
TR 2: Damper/sustain (cc64)
TR 3: Generic (cc80)
TR 4: MIDI clock (16th note timing as of firmware 1.4)

+/- 1 octave pitch bend supported.

Allocation style 3: MULTI

4 pairs of CV/TR mapped in simple MONO pitch/gate outputs responding to MIDI channels 1-4.

Allocation style 4: FIXED

TR mapped to notes C4, D4, E4, F4 (60,62,64,65).

CV mapped to CC 16,17,18,19

Enter learning mode by holding Key 1 and pressing preset (all CV/TR will clear). As unique notes and/or CC messages are received they are mapped to the next available CV/TR output respectively. Once all outputs are mapped all LEDs will go out. Press Key 1 (panic) to cancel learning.

Preset

as of Ansible firmware 1.4

Holding Key 2 and a short press on preset saves the current value for the following to flash as the default (mode light blinks once):

  • selected voice allocation mode
  • pitch slew (set via teletype)
  • pitch offset (set via teletype)
  • fixed mapping

Holding Key 2 and a long press on preset will clear the stored configuration and reset back to default values (mode light blinks twice).

The default pitch offset is -2 octaves which is the equivalent of issuing the following Teletype command MID.SHIFT N -24.

MIDI/arp

The mode LED will show white when running.

Interface

  • Key 1: tap tempo / force internal clock (press twice)
  • In 1: sync / ext clock

  • Key 2: arp style:
    • as played (as of firmware 1.4)
    • up
    • down
    • up/down (tri)
    • up and down (repeat high/low note)
    • converge
    • diverge
    • random
  • In 2: reset

Each CR/TR pair is a voice playing the arpeggio at a different divisions of the clock, initially divisions of 1,2,3,4 respectively.

Additional parameters can be controlled via CC input:

  • CC 16: Internal tempo (when not clocked by in 1 or MIDI clock)
  • CC 17: Gate length (course divisions sync’d to the clock)
  • CC 18: Scale clock division for voices 2-4:
    • 1,2,3,4
    • 1,4,6,8
    • 1,6,9,12
    • 1,8,12,16

If MIDI clock is received it will be used as the clock source when no external clock is present.

Preset

as of Ansible firmware 1.4

Holding Key 2 and a short press on preset saves the current value for the following to flash as the default (mode light blinks once):

  • clock period
  • selected arp style
  • hold mode (on/off)
  • pitch slew values
  • pitch shift values
  • pattern repeat values
  • euclidean rhythm parameters (accessible through Teletype)

Holding Key 2 and a long press on preset will clear the stored configuration and reset back to default vaules (the mode light blinks twice).
