ABOUT a preset version of the OBX..
ABOUT eine Preset-Version des OBX..
DETAILS allows V/Oct control. Xmod but 12dB mode only, still very good sounding, still. unison mode! but very limited since it has no knobs.. it's a preset synth.. difference Oberheim OB-X vs. OB-Xa OB-X = discrete analogue circuitry, possibly SSM? OB-Xa = Curtis Chips the OB X wasn't part of the x-system all x-synthesizers are compatible optically and dimensions the ob-x has Crossmod which never came back on the later machines ob-x and ob-8 the Xa added a split/double mode and was expandable from 4 to 8 voices with 2-voice cards.. and it also had 2 and 4pole filters, the obx had no 4pole mode.. the OBX has Crossmod. the OBXa hasn't, but the OBx has no self oscillating filters (12dB/oct is often limited to non max reso/self oscillating) OBSX: a preset version of the OBX - Hardware: 2 CEM3340 VCO 1 CEM3320 VCF 2 CEM3310 EG 1 CEM3360 Dual VCA
DETAILS V/Oct steuerung. Xmod, keinen 4pol mode, aber dennoch unglaublich gut im sound. unisono mode. leider nicht programmierbar. Hardware: 2 CEM3340 VCO 1 CEM3320 VCF 2 CEM3310 EG 1 CEM3360 Dual VCA
SOUND wide and big pads and sweeps with soft character, one of the best you can get. leads and basses also very fat. watch the internal trimmers, they may need some special watching.. very limited bec ause if no knobs , presets only..
SOUND generell flächiges und tolle sweeps, fette Leads und Bässe.. Tolle Maschine, etwas anfällige interne Trimmer. aber leider sehr eingeschränkt durch fehlende regler..
VERSION versions 4 or 6 voices.
VERSION Versionen mit 4 oder 6 Stimmen.

OBERHEIM or Gibson, Oberheim-Viscount Joint Venture, Viscount

today owned by Gibson and lendet to Viscount. Tom Oberheim started it (of course he left when Gibson took over). He built Synth Modules (SEM) to be played via other synthesizers and ppl wanted him to built synths: he did. he took SEMs and made polyphonic synths out of them. the latest synth was the Xpander and Matrix12, the OB-Mx wasn't a real Tom Oberheim anymore, so they got Don Buchla finishing it (it did not sell well), so the OB12 as only the name in common with the founder. Mr Oberheim tried again under the Marion System name.

The "real" Tom Oberheim is now producing under his full name guess his site -
