Update: note the description appears to be pulled from this other listing on reverb. The pics and serial number are different. As always, adhere to eBay's and Reverb's buyer guidelines to protect yourself.

"The Prophet-5 actually contains five individual synthesizers, termed “voices”. For its producible sound sources, each voice contains two voltage controlled oscillators (VCOs), referred to as OSC A and OSC B. OSC A, OSC B, and a white noise source can be mixed into a resonant low-pass voltage controlled filter (VCF). The filter modifies the voice timbre under control of its four-stage envelope generator. The filter may also serve as a sound source. Following each filter, a voltage-controlled amplifier (VCA) also controlled by a four-stage envelope generator shapes the voice amplitude. Only one voice is depicted on the control panel, because the voice controls “patch” the five voices identically. This makes the voices homophonous— they sound alike— with pitch differences corresponding to (at most) five keys simultaneously-held keys. The term “digital-analog hybrid” is often used to described the Prophet. This means that instead of directly controlling the analog synthesizer voices, the keyboard and most controls are actually devices which input “data” to a microcomputer system which in turn “programs” the voices. The microcomputer has three main functions. First, it solves the of generating five independent sets of voice control voltages and gate signals (which operate the envelope generators) from a single keyboard. Second, its digital memory provides a way to store all of the switch and knob settings which form a program. These programs are retained by the microcomputers memory even when the Prophet is turned off, thats to a small battery with a 10-year life. Third, the microcomputer system keeps the ten voice oscillators in tune."

Super Gemini - Hazel Mills' Split Mode Exploration

video upload by UDO Audio

"More from Hazel and the Super Gemini, this time giving us an exploration of Split Mode.

Within Split Mode, the upper and lower layers are mapped either side of a split point on the keyboard, with the 20 available voices split evenly between the two. The upper layer is assigned to all keys above the designated split point, while the lower layer is assigned to all keys below. For a "Pro hack", hold the SPLIT button, and you can set the split point by pressing a key.

This feature opens up a wealth of opportunities, ultimately giving you the possibity to control two "seperate instruments" on one keyboard!

Let us know what you think in the comments section below.

RK008 Menus: ALT+2 - PART / TRACK COPY, SWAP & EXPLODE

"ALT+2 means COPY: Operations where you can copy, swap and explode your RK-008 recordings.

(PS - I'll try to align the recording with the RK008 buttons next time, the video is not very helpful on led feedback this way...)"

Pulsar From Mars

video upload by Samples From Mars

https://samplesfrommars.com/products/... "Controlled Chaos From Our Favorite Modern Drum Machine
The Pulsar 23 is a semi-modular, analog drum machine from SOMA Laboratories, and the second in their line of "organismic" synthesizers. Despite its intimidating look, this mashup of classic and modern analog synthesis provides immediate fun and inspiration, so it's no wonder it was your #1 choice for what we should sample next! (via a survey we sent out earlier this year).

So much more than just blips and beeps, the Pulsar's 23 modules give this machine an un-rivaled, vast sonic pallet that allowed us to sculpt some of the most unique loops and one-hits we've ever made."
