An intuitive "hands-on" interface makes realtime operation easy for artists with a DJ background, while in-depth sequencing and editing functions make it possible to create the most complex original patterns from scratch.

The RM1x also features a great-sounding tone generator with an enormous selection of great dance sounds built in. If dance is your style and you want the most powerful performance and production tools right at your fingertips, it doesn't get much better than this: the Yamaha RM1x Sequence Remixer.
An extensive arsenal of 700 outstanding dance-oriented sounds. An awesome assortment of 50 preset styles, 960 pattens ans, 726 phrases.
8 assignable real-time control knobs, a large LCD display panel with 4 display knobs and a large multi-function keyboard.

Each "style" has up to 16 "sections" which can be switched in real time during playback via the RM1x keyboard.
Powerful 16-track sequencer with 110,000-note memory and 480 clocks/quarter note resolution lets you record original material via the RM1x keyboard or an external MIDI keyboard using a versatile range of record modes: realtime replace, realtime overdub, punch-in, step, and grid.
In-depth sequence editing functions make it possible to creat and refine complex patterns and musical textures with extraordinary precision.

Edit and refine the RM1x voices to create sounds that most ideally suit your own music.
A sophisticated multi-effect system can be used to add anything from subtle ambience to wild variations.
Realtime “Play Effects” including harmonize with unison and octave functions, beat stretch, clock shift, gate time, and velocity offset.

Wiard VCO

via this auction
"Wiard 300 series classic VCO
The Classic VCO is the highest quality analog oscillator module ever made. It produces the standard classic analog waveshapes -- sine, triangle, sawtooth and pulse with pulse width modulation. It also has a unique random voltage output which provides 64 random voltage levels. In the audio range, this sounds like "noise" of various colors depending on the tuning of the oscillator. In the "low" range, it can be used in the same way as a noise generator feeding a sample and hold. The Classic VCO has three exponential control inputs, one with attenuator. It also has an AC coupled linear input with attenuator and a propotional sychronization control with attenuator. In addition, this module contains a simple attack-release envelope generator (which can also be used as an envelope follower or lag processor) and a voltage controlled amplifier (VCA) with two mixing inputs. The VCA is intended to be used with the "Velocity" output of a MIDI to CV convertor but can be used as a general purpose VCA. The modulated pulse output is normalized to one VCA input while the output of the envelope generator is normalized to the VCA control input. Red and Green Bicolor LEDs monitor three of the waveform outputs and the voltage output of the envelope generator is displayed by the brightness of a fourth LED. The output level of the VCA is displayed on a four LED VU meter. The Classic VCO module contains: A five waveform pure analog oscillator An Attack-Release Envelope Generator. The envelope is set by an internal jumper for either exponential or linear envelopes. A Voltage Controlled Amplifier (VCA) A jack multiple"
