Demo of the 40 factory patch sounds from the Prophet 5 (Rev 3.2). This is not intended to be musical, just a demo of the sounds. I am far better at fixing them than playing them. Buy this Prophet 5! Sequential Circuits Prophet 5 Keyboard Synthesizer Pro Overhauled Rev 3.2 Excellent.
The Prophet 600 'Gligli' Firmware Upgrade rev. 'Stable 2.0' hosts the following improvements:
1. Easy-to-install non-destructive firmware drop-in replacement of the new firmware. If you ever find yourself pining for the old sound of your Prophet 600, you can remove the Gligli upgrade and restore the Z80.
2. Greater resolution of many of the sound parameters with an improved refresh rate that is making the instrument much more responsive. Forget those lousy stepped cutoff changes!
3. Faster, smoother amplifier and filter envelope generators supporting four different modes:
1. Fast Linear.
2. Slow Linear.
3. Fast Exponential.
4. Slow Exponential.
4. A new LFO function generator with a wider range from one cycle every <20 seconds> to about 60Hz with four new waveforms in addition to the original triangle and square including sine, random stepped, noise (like on the original Prophet 5, but nonperiodic) and sawtooth (ramp up).
5. A dedicated vibrato which can be controlled by the modulation wheel, or can start progressively after a fixed amount of time.
6. Multiple keyboard modes including last/low/high note priority.
7. Unison detune.
8. Mix Overdrive which now allows the output from both oscillators to drive the mix VCAs A and B harder as well as the Curtis 4 pole filter resulting in new sonic possibilities.
9. Pitch Wheel interval selection of plus/minus one octave, a whole tone, a minor third and a fifth.
10. Pitch Wheel reassignment to the VCF and Volume or off.
11.Modulation wheel intensity setting from Maximum to Medium to Minimum.
12. Full Midi In control including:
1. Amp and Filter velocity sensitivity with an external keyboard controller.
2. Continuous Controllers (CC) of all sound parameters.
3. Program change (PC) to choose current preset.
4. Synchronizing the arpeggiator to MIDI clock.
13. A new and improved tuning procedure.
14. Octave, chromatic and free Oscillator course pitch control.
15. Plus/Minus setting for Oscillator Fine Tune and Filter Envelope amount for Poly Mod and Filter.
16. Assignable, Random And Up/Down Arpeggiator.
17. Debounce feature that prevents unintended retriggering caused by the old keyboard.
(Redirected from Sequential Circuits Prophet-5)
The Prophet-5 is an analog synthesizer manufactured by Sequential Circuits between 1978 and 1984. It was designed by Dave Smith and John Bowen. The Prophet-5 was the first fully programmable polyphonic synthesizer and the first musical instrument with an embedded microprocessor. About 6,000 units were produced across three revisions. It has been emulated in software synthesizers and analog hardware.
Production[edit]
The Prophet-5 was created in 1977 by Dave Smith and John Bowen at Sequential Circuits, who aimed to create the first polyphonic synthesizer with the ability to store and recall patches.[1] Initially, they developed the Prophet-10, a synthesizer with ten voices of polyphony; however, it was unstable and quickly overheated, creating tuning problems. Smith and Bowen removed half the electronics, reducing the voices to five and creating the Prophet-5.[1]
Smith demonstrated it at NAMM in January 1978 and shipped the first models later that year.[2] Unlike its nearest competitor, the Yamaha CS-80, the Prophet-5 had patch memory, allowing users to store sounds rather than having to reprogram them manually.[3]
Three versions were built between 1978 and 1984. The first, Revision 1, was hand-assembled and produced quickly to generate initial revenue; only 182 were made. Revision 2 was mass-produced in quantities over 1,000; this model was more robust, added cassette patch storage, and replaced the koa wood casing with walnut.[1]
Revision 3 replaced the Solid State Music (SSM) chipset with Curtis Electromusic Specialties (CEM) chips, necessitating a major redesign. According to Sound on Sound, Revision 3 'remained impressive and pleasant to play, but was slightly cold and featureless by comparison to earlier models'.[1] In all, approximately 6,000 Prophet-5 synthesizers were produced.[1]
Prophet-10[edit]
In the Prophet-10, a pair of Prophet-5 sound boards provide ten voices
In 1981, Sequential Circuits finally released the Prophet-10 synthesizer, featuring 10 voices, 20 oscillators, and a double manual keyboard. Like the Prophet-5 Revision 3, it uses CEM chips.[1] The first Prophet-10s used an Exatron Stringy Floppy drive for saving patches and storing sequencer data. Sequential later moved to a Braemar tape drive, which was more reliable and could store about four times as many sequencer events.[1]
Impact[edit]
The Prophet-5 became a market leader and industry standard.[3] It has been used by acts including Michael Jackson, Tangerine Dream, Madonna, Patrick Cowley, Dr Dre,[3]Too Short, Radiohead,[4]John Carpenter, Alan Howarth,[5] and John Harrison.[3]Brad Fiedel used a Prophet-10 to record the soundtrack for The Terminator (1984).[6]
Synthesis[edit]
Early Prophet-5s used voltage-controlled oscillator, filter and amplifier chips designed by E-mu Systems and manufactured by Solid State Music (SSM). Revision 3 Prophet-5s used Curtis CEM chips manufactured by Curtis Electromusic Specialties. Some owners maintain that SSM oscillators produced a richer timbre.[7] However, the SSM oscillators rendered the instruments unstable and prone to detuning over time. CEM chips have remained more stable.[8]
The Prophet-5 uses five voices of polyphony. Each voice is assigned two VCOs. Both oscillators can generate sawtooth waves and square waves (with variable pulse width), and the second oscillator can also generate a triangle. The oscillators can be played in sync, or in 'Poly-Mod', with oscillator B and the filter ADSR envelope modulating the frequency, pulse width, and filter of oscillator A. A dedicated low-frequency oscillator (saw, square, or triangle) is also present to modulate the pulse width and/or pitch of oscillators A and B and filter cutoff frequency.[7]
The Prophet-5 uses a 4-pole resonant low-pass filter. The filter has a dedicated ADSR envelope and keyboard tracking.
Successors[edit]
DSI Prophet '08 (2007)
DSI Prophet 12 (2014)
Sequential Prophet-6 (2015)
Arturia developed a softsynth version of the Prophet 5, the Prophet V. Prophet V also includes a recreation of the Prophet VS, a synthesizer manufactured by Sequential Circuits in 1986. Elements of the two synthesizers can be combined in a 'hybrid' mode. The softsynth closely recreates the layout of the original analog synthesizer, though there were some differences in programming, notably through some restrictions on the envelope generator.[9]
In January 2015, Smith announced that Yamaha's president, Takuya Nakata, had granted him rights to the Sequential brand, which he had been unable to use following the company's acquisition. The release of the name coincided with Smith's debut of the Prophet-6, a new analog polyphonic synthesizer based on the Prophet-5 with additional features. Of the Prophet-6, Smith said 'I wanted to celebrate the return of Sequential in the best way I could—by building the most awesome-sounding, modern analog poly synth possible. The Prophet-6 is a tribute to Sequential's most famous instrument, the Prophet-5. I think of it as vintage with a modern twist.'[10]
