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 values (the mode light blinks twice).
