1. Connect your True Spring Reverb to the Neuro Desktop Editor.
2. In the top bar menu select Device > Edit Device MIDI Map from the dropdown menu.
3. The True Spring Reverb MIDI Map Editor window will open. Scroll to the MIDI CC value you
wish to map and select that CC's dropdown menu. A list of parameters will unfold.
4. Select the parameter you wish to assign to the chosen CC. The process is complete.
For parameters like Mix and Level, which are normally controlled by knobs, the full range of
continuous control values from 0 to 127 will be mapped to the range of the knob.
For the engage/bypass footswitch, continuous control values in the range of 0-63 will bypass the
True Spring and values in the range of 64-127 will enable the pedal.
For the effect type switch, continuous control values map directly to each effect type. 0 = SHORT, 1 =
LONG, and 2 = TANK. Other values map to additional effect types that are available in the Neuro App.
Any MIDI CC, from 0 to 127, can be mapped to a control on the True Spring.
Each CC number can only be mapped to control one parameter at any given time. If you attempt to
map a CC that has already been assigned to another parameter, the previous mapping will be
overridden.
Several CCs can potentially be mapped to the same parameter, although this is not very useful.
Erase MIDI Mapping
To clear MIDI mapping, first press the Control Input button and turn off Control Input mode. The
Control LED should be dark. Then, press and hold the Control Input button until the Control LED
blinks. This clears all Expression, Hot Hand, and MIDI mapping.
MIDI Clock
The True Spring's tremolo and reverb modulation will sync to MIDI clock messages (also known as
MIDI timing clock or MIDI beat clock). MIDI clock is tempo-dependent and is used to ensure that
multiple MIDI-enabled devices stay in synchronization. A common use of MIDI clock with the True
Spring is when recording along to a click track in a DAW (Digital Audio Workstation) running on a
computer. MIDI clock can be sent to the True Spring directly over USB-MIDI or via the Control Port
from the Neuro Hub.
MIDI Clock can be enabled within the True Spring on a per-preset basis. To enable MIDI Clock go the
the External Control section of the Neuro Desktop's Sound Editor interface and select the Sync to
MIDI Clock button. The True Spring begins its MIDI Clock sync as soon as the first MIDI Clock message
is received. If the tempo changes, the rate of MIDI Clock messages will change as well, and the True
Spring will adjust to resynchronize itself accordingly.
Use the Nuero Desktop Editor to select which parameter responds to the incoming MIDI Clock
messages. In the Tap Tempo section of the Sound Editor, use the Assign dropdown menu to select
the affected parameter; options include Tremolo, Reverb Modulation, or Both. Use the Beat Division
dropdown menu to select the rhythmic subdivision of the incoming MIDI Clock. The Beat Division
options are Quarter, Eighth, Dotted Eighth, Triplet, and Sixteenth notes.
