Oberheim OB-8

images via this auction
"equipped with factory MIDI and has the page 2 silk-screened on the front panel. It has an elaborate modulation routing configuration, especially with the "page 2" options which gives you a full additional set of parameters like an envelope (invertable!)for the lfo..speed and/or depth delay, just to name two! It has an extra LFO on the bend panel, also with many features: 6 waves from which to choose- up saw, down saw, square, S/H, noise, and triangle. Route to OSC 1, OSC 2, or both, and again, completely independent of the front panel LFO, which is probably already doing its own modulations on PW, FILTER, VCOs, and VCA.

THE ARPEGGIATOR (!) was way ahead of its time with the ability to program the intervals at which it can arpeggiate: DOWN, UP, UP/DOWN, and RANDOM. Yes, you do not have to rely on the $4000+ Jupiter 8 for the same (if not better)random arpeggiator ! It's hidden from the functions silk-screened on the bend panel, as are the programmable intervals, etc... Right now, it's programmed to arpeggiate octaves, (same as Jupiter 8's RANGE). It Sounds amazing and is the OB-8's best kept secret.

The OB-8 has 16 VCOs, 8 VCFs with 2 modes, and 16 VCA/EGs."

Vermona DRM1 MKII Analog Drum Synthesizer

images via this auction
"The DRM1 MKII is an eight-channel, completely analog drum synthesizer. It gives you total control over every parameter through its 72 controls.

Each channel features specific parameters for generating a certain kind of drum and/or percussive sound. They are divided into:

- three DRUM channels
- one MULTI channel
- one SNARE channel
- two HI HAT / CYMBAL channels
- one CLAP channel

In addition to the main stereo output, every channel is also equipped with an individual output / insert jack, which allows you to insert external effects.

Each channel has its own output/insert jack on the front panel. The rear panel features the master output (L/R), as well as the MIDI IN and THRU jacks. The DRM1 MKII has an integrated power supply.

The design and construction of the chassis makes it possible to use the DRM1 MKII either in a 19" rack (5U) or as a tabletop unit with the front panel tilted on a convenient angle.

The DRM1 MKII can be triggered via MIDI - MIDI channel and note number can be freely assigned."
