This SE-1X is fully functional and in very good condition.
From Studio Electronics:
Seen where the sound of success was heard, the SE-1 recreated the power of the classic Moog tone and far more. The distinctive Oberheim filter and numerous additional features helped to make this Hiphop and R&B legend the serious professional's source for the boominest basses and smoothest, wormiest leads on the planet.
The SE-1X continues in this tradition, remaining true to its roots, while stepping up its functionality and form, wide open to future expansion and exploration via its Flash-ROM operating system and dedicated creativity of its supernal sound designers.
Three voltage controlled discrete analog oscillators, triangle, sawtooth and variable width square waveforms. All waveforms output simultaneously. Osc 1 syncs to Osc 2 and 3.
Two voltage controlled discrete analog filters: 24db (classic Moog®), 12db (classic Oberheim®). 12db filter incorporates low pass and band pass modes.
Four multiple stage envelope generators, attack, decay, sustain and release with inverting and multiple triggering. Envelope 1 fixed to filter frequency. Envelope 2 fixed to amplifier level. Envelopes 3 and 4 are assignable.
Three low frequency oscillators, triangle, sawtooth, reverse sawtooth, square, noise and random waveforms. One destination and amount for each LFO with key trigger, phase and midi sync.
Glide and auto glide, linear or exponential.
Noise generator, hardware ring modulation, external audio input (requires midi trigger to open gate).
LFOs 1, 2 and 3: VCOs 1, 2 and 3 frequency; VCOs 1, 2 and 3 mix level; VCOs 1, 2 and 3 pulse width; ring mod mix level; noise mix level; VCF resonance; VCF frequency and volume. Envelopes 3 and 4: VCOs 1, 2 and 3 frequency; VCOs 1, 2 and 3 mix level; VCOs 1, 2 and 3 pulse width; ring mod mix level; noise mix level; LFO 1, 2 and 3 rate and depth and VCF resonance.
Dynamics, modwheel, pressure and breath control: destinations and amounts include all LFO and envelope 3 destinations; bender: pitch and filter frequency; receives program change, bank select, glide on/off, glide time and volume. Fixed continuous controller assignments for all key front panel controls.
