Studio Electronics SE-1X User Manual

In addition to the aforementioned "Safety Instructions" printed on the inside front cover,

we the good folks at S. E. ask that you please read and adhere to the following sugges­tions.

POWER SUPPLY CONCERNS

Turn off the power to all equipment before making any connections between devices. This will help to pre­vent malfunction and speaker damage.

Be certain to use a separate power outlet for this unit; as sharing one with distortion producing devices (such as
motors, variable lighting devices) is unwise.

PLACEMENT CONCERNS

Placing the unit in close proximity to power amplifiers or equipment containing large transformers is likely to in­duce hum.

If the unit is to be operated nearby T.V. or radio receivers, some type of interference might be noticeable. In such
cases, move the unit out of proximity with the entertainment devices.

MAINTENANCE

In hopes that you might keep the visuals of your treasured analog gem in tip top shape, our cleaning specialists
recommend wiping ever so gently with a slightly dampened soft cloth. For those stains of a more tenacious tem­prement add a mild detergent to the mix; always remembering to follow with that ubiquitious "soft dry cloth".

Never apply solvents of any kind - benzene, paint thinner, propyl alcohol, etc., to avoid the risk of nasty discol­oration, disfigurement a n d most importantly those deadly liver flukes. (It should be parenthetically noted that neither

solvents nor the unit itself are ever to be taken internally!)

OTHER PRECAUTIONS

Protect the unit from strong jolts and vibration. Especially when standing on well established fault lines.
Never apply strong pressure to the front, back or side panels, or strike them in any manner whatsoever.

Yelling, however, is certainly permissible and quite cathartic.
It is normal for this compressor/ limiter to generate a certain degree of heat.

Welcome to the world of discrete, programmable Analog synthesis, and the amazing
sounds it produces. The SE –1 is inspired by the classic circuitry of the Minimoog
Filter, Oscillators, and VCA. We've also incorporated “our take” on the “boxy”, buzzy,
and bright 12-dB filter of the Oberheim S.E.M., for greater tonal expression. Four
envelopes, three LFOs, full MIDI implementation, and a host of original extra features
await you. And, of course, the legendary, the immortal, and the ubiquitous: Bank A,
patch #04...

This manual is divided into sections that correspond to the SE -1's front panel. Let's
begin apprentice Analogians.

Wave form selection: (Triangle) (Sawtooth) (Pulse). These can be selected either
individually or collectively.

PULSE WIDTH: Adjusts the harmonic content of the pulse wave. A square wave can
be obtained by setting the knob at 12 o'clock. (Effective when pulse wave is selected)

FREQ 1, FREQ 2, FREQ 3: Controls the pitch of each oscillator. Stepped (quantized)
in semi-tones over a five octave range

SYNC 2: Forces Oscillator 2 to follow Oscillator 1 in hard synchronization so it will
therefore tune only to harmonic frequencies of Oscillator 1. Intermediate frequency
settings of Oscillator 2 will produce unusual wave shapes and timbres.

SYNC 3: Forces Oscillator 3 to follow Oscillator 1 in hard synchronization...

* Use sync feature in conjunction with Envelopes 3 and 4 assigned to Swp 2, and or
Swp 3 for subtle and dramatic harmonic filtering effects.

OSCILLATOR TUNE PAGE

Displays octave and fine-tune settings of oscillators.

Functions accessed on this page:

MASTER TUNE: Continuously varies overall pitch flat or sharp just over a semi-tone.

FINE 2: Continuously varies pitch of Oscillator 2 flat or sharp just over a semitone.

FINE 3: Continuously varies pitch of Oscillator 3 flat or sharp just over a semitone.

FILTER

FILTER

FILTERFILTER

FREQUENCY: This adjusts the cutoff frequency of the 12db and 24db filters. It is
rather like a tone control. As you rotate the knob clockwise, the higher the frequencies
are which pass through the filter; thus, the brighter the sound.

RESONANCE: Adjusts the amount of filter resonance, which emphasizes the cutoff
frequency region and makes the presence of harmonics more apparent. As the knob
setting is increased beyond 3 o'clock (24db filter only) the filter begins to oscillate, and
acts like a sine wave audio source.

24DB: When lit, the 24db (Moog) filter is active. When not, the 12db (S.E.M.) filter is
active.

TRACKING: Applies keyboard CV (control voltage) to the filter. The more tracking
used, the brighter the sound will get as you ascend the keyboard.

ENVELOPES

ENVELOPES

ENVELOPESENVELOPES

The SE -1 has four envelopes. Envelope 1 is permanently assigned to the filter, and
Envelope 2 is permanently assigned to the amplifier. Envelopes 3 and 4 can be
assigned to a variety of functions via the edit page.

VCF

VCF

VCFVCF

The filter envelope generator shapes the timbre by controlling the filter cutoff frequency
and resonance. The contour pattern is initiated when a key is struck, producing a gate
(or note). The initial appearance of the gate triggers the envelope to proceed through
its ATTACK and DECAY times. After the ATTACK and DECAY times have elapsed,
the generator will produce a steady control voltage; playing the sound at the level set by
the SUSTAIN knob for as long as the gate (or note) is held. When the key is released
the RELEASE knob sets the rate at which the sound disappears.

ATTACK: Adjusts the length of time for the envelope generator's output to go from
zero level (when key is initially pressed) to maximum level.

DECAY: Adjusts the length of time for the envelope generator's output level to go from
maximum level to sustain level.

SUSTAIN: Adjusts the sustain level from zero to maximum. This is a level control, not
a time control. Sustain time is determined by touch. If sustain is set at maximum, then
the decay knob setting is irrelevant. There is no level below maximum to which the
envelope can decay.

RELEASE: After releasing key, adjusts the length of time for the envelope generator's
output to go from sustain level to zero. If sustain is set at zero, then the release knob
setting is irrelevant. There is no level from which the envelope can release.
