POWER
Plug one end of the supplied AC cord into the standard IEC power connector on the Subsequent 37’s
left-side panel. Plug the other end into an AC outlet. Warning: An apparatus with CLASS I construction
(such as this device) shall be connected to a MAINS socket outlet with a protective earthing connection.
The Subsequent 37’s universal power supply will operate with 50/60Hz AC power sources ranging from
100 to 240 VAC / 50-60 Hz using 13W. Flip on the power switch located next to the power connector.
NOTE: It may take as long as 60 seconds for the Subsequent 37 to warm up before oscillator tuning has
stabilized if you’ve left it outside on a cold night. (Although its oscillators are surprisingly stable, the
Subsequent 37 is an analog synthesizer, after all.)
AUDIO OUT
With the MASTER VOLUME turned all the way down, plug one end of a 1/4 inch instrument cable into the
Subsequent 37’s AUDIO OUT jack and the other end into an amplied speaker or mixing console input.
Adjust the level by slowly turning the MASTER VOLUME knob clockwise while playing the keyboard.
If you’ll be using headphones, plug them into the headphones jack (on the front panel’s bottom-right
corner) with HEADPHONE VOLUME turned all the way down. Adjust the level by slowly turning the
HEADPHONE VOLUME knob clockwise while playing the keyboard. Note that MASTER VOLUME
must be turned up as well.
EXTERNAL AUDIO IN
Located just above the AUDIO OUT jack, the jack labeled EXT IN allows the Subsequent 37 to shape and
lter external sounds. This is an unbalanced input that accepts a line-level signal.
NOTE: You must press a key to pass external audio through the Subsequent 37. You also can use a Moog
FS-1 footswitch, or simply press the LATCH ON button in the Amplier Envelope section and make sure that
the Amplier Envelope’s SUSTAIN level is up.
USB
To use the Subsequent 37 with a computer, connect one end of a USB cable to the Subsequent 37’s
USB port and the other end to an available USB port on your computer. The Subsequent 37 supports
MIDI I/O over USB, but not audio data. The Subsequent 37 is class compliant. No drivers are required
for USB MIDI connectivity.
MIDI
Using the Subsequent 37 with an external MIDI device requires one or two MIDI cables. To use the
Subsequent 37 as a MIDI controller, connect one end of a MIDI cable to the Subsequent 37’s MIDI OUT
jack and the other end to another device’s MIDI IN jack.
To control the Subsequent 37 from an external MIDI controller, connect one end of a MIDI cable to the
Subsequent 37’s MIDI IN jack and the other end to an external controller’s MIDI OUT jack. By default,
the Subsequent 37 is set to transmit and receive MIDI data on MIDI Channel 1.
CONTROL VOLTAGE IN
The PITCH CV, FILTER CV, and VOL CV inputs each accepts an expression pedal (such as the Moog EP-
3) or a control voltage signal from 0 to +5 volts. If you connect a TRS expression pedal to VOL CV, you
can use your foot to control the Subsequent 37’s output level. If you connect a TRS expression pedal to
FILTER CV, you can sweep the lter cutoff in the same manner. The PITCH CV input is calibrated so that
a one-volt change in the control voltage will result in a one-octave change in frequency.
The KB GATE input accepts a +5 volt signal, which causes the Subsequent 37’s envelopes to trigger.
