REVERB OUT
This 3.5mm output provides a separate output directly from the Spring Reverb
tank at typical Eurorack audio levels. When combined with the REVERB IN
patch point on the front panel, this jack allows the Spring Reverb to be used
as a standalone processor.
ARP / SEQ CV
This group of jacks is dedicated to synchronizing the Arpeggiator
or Sequencer with other analog instruments.
CLOCK IN
This input allows Grandmother to be synchronized to an external clock source
such as a DFAM, Mother-32, or any other instrument that outputs clock sync.
There are two modes for this jack, Clock or Step-Advance. In Clock Mode,
the timing of clock pulses received at the CLOCK IN sets the tempo of the
Arpeggiator and Sequencer, according to the Clock Input PPQN (Pulses Per
Quarter Note), which is set in the Global Settings (see p.38). In Step-Advance
mode, the Sequencer or Arpeggiator pattern is advanced by one step each
time the rising edge of a gate or pulse signal is detected at the Clock Input.
ON / OFF IN
A +5V signal received here will cause the Arpeggiator or Sequencer to Play,
while a 0V signal received here will cause the Arpeggiator or Sequencer to
stop.
NOTE: Signals with a voltage greater than 2.5 Volts will activate the ARP / SEQ;
signals with a voltage less than 2.5 Volts will deactivate the ARP / SEQ.
RESET IN
A +5V signal received here will cause the Arpeggiator or Sequencer to reset to
the beginning of the pattern or sequence without stopping.
NOTE: The RESET IN jack responds to voltages greater than 2.5 Volts.
CLOCK OUT
This output allows Grandmother to transmit clock sync to other instruments
based on the ARP / SEQ RATE knob setting , and the Global CLOCK OUTPUT
PPQN setting (see p. 38). Grandmother can also send Clock information via MIDI.
