The Performer is a polyphonic analog Strings and Brass machine produced at the end of the 1970’s by the Italian synth company. It is slightly compact with just 49 keys. But it is fully polyphonic – you can play all 49 notes simultaneously! Programming is simple and clearly laid-out with just 15 sliders and a few buttons. A solid black chassis and wood end-cheeks round out this classic and often overlooked string machine.
The Performer is best remembered for its Strings. A simple 3-band equalizer with high, mid and low sliders can be used to give the strings shimmering sparkle or moody dark timbres. The Strings section uses two oscillators per voice with 8′ and 16′ settings. Simple Attack and Sustain sliders give you some control of your string’s envelope settings.
The Brass section is less exciting. It uses a single oscillator with just a square wave to generate a weak Brass sound. It has a low-pass VCF filter with resonance, but it too is pretty weak. Simple Attack and Decay sliders control its limited envelope settings too.
The LFO is pretty nice, with delay length, rate and depth control. It can modulate both Brass and String sections and can be routed either to the VCF or pitch. There are three outputs on the back: main output, brass output and signal output (for external processing) as well as CV and Gate connections.
Synthesizer Demo of the polyphonic analog synthesizer Roland Alpha Juno-2. The Alpha Juno-2 is played dry without any additional effects.
This is an upgraded version of the Alpha Juno 1. It adds an extended 61 note keyboard with velocity and aftertouch and an external memory cartridge slot. Other than that it has the same great sound and features as the Juno 1. Sliders and buttons were replaced by membrane buttons and the Alpha Dial which is used to edit and browse through the extensive selection of parameters: DCO digitally controlled oscillators, LFO, bend, ENV, pulse, waveforms, noise, PW/PWM, high pass filter, VCF (filter) with freq/env/res/lfo/kybd, VCA envelope, chorus, and more.
Adequate in the studio or on the stage, the Juno 2 has 64 presets and 64 user memory patches, a nice LCD display, an LFO capable of a very slow rate for some cool sweeping effects, and a great bass sound (especially nice for acid basslines) and noise effects! It also has chord memory which is perfect for rave & techno, portamento and keyboard transposing. The PG-300 Synthesizer Programmer gives you traditional slider control of each parameter for much easier and faster editing.
This video features a prototype of a new synth called XOR and is actually a true digital polyphonic synthesizer, details below:

Arduino programming compatible – running on atmega 328
based on fraAngelico synthesizer
-polyphony 6 voices
-selectable wavetable (sine,saw,triangle,noise)
-selectable bitoperator that modulates the wave (xor, or, and)
If you make Ellipsynth monophonic (by setting the polyphony to 1), it’s pretty easy to make a sound scrubber. You can actually do this polyphonically as well, but it’s easier to control with just one voice. Here, I’m not playing with the pitch or the playback speed too much, but you can see what that might get you.
WOPR is a polyphonic, stereo virtual analog synthesizer with totally unique evolving modulation driven by vintage 1970s cellular automata. It’s made for iPad 2 or later only. WOPR is a performance instrument, a stand-alone instrument in the same spirit as the Korg Monotron.
It’s brilliantly playable: the full-width Wribbon keyboard lets you play pitch-perfect notes every time, then bend them like a guitar god to convey your inner pain to the screaming masses.
It’s performance-friendly: you can create customized control panels for comfortable access to parameters. That’s much better than contorting your fingers to fit some tiny panel layout.
WOPR is a seriously powerful analog, but what sets it apart is its modulation grid: you paint a pattern of cells into a grid, set the tempo, hit ‘run’ and let the cellular automata evolve your pattern. You link areas of the grid to any of the synth’s parameters and your patches come to life, rhythmically pulsating as the patterns shift with each beat. Constrain parameters to ranges for tight control over rhythmic modulation, or set them free to dynamically breed new patches.
Being a virtual analogue synthesizer, we’d be remiss if we didn’t include some allusion to the past. Here it is: the modulation grid is a bona fide 1970s invention called Conway’s Game of Life. Look it up, marvel at the infinite variety of patterns, geek out on the math, then put them to work twisting knobs in WOPR.
The core synth engine justifies its powerful modulation. WOPR has:
– 2 pannable oscillators with sine, saw, square and triangle waves. Each oscillator has an incredible range: 32′ to 1′, with +/- 500 cent detune (a perfect fourth either way). There’s also a white noise generator.
– 3 ADSR envelopes, 2 assignable between osc 1 & 2 and the third dedicated to the noise source.
– 2 fruity, resonant 24Db/octave low pass filters, assignable to osc 1 & 2 or to the left and right stereo channels.
– 2 delays, a free-running delay with fine control over low intervals, and a tempo-synced delay running from 32nds to two whole beats. Delays are independent, or can be assigned to feed eachother in any sequence. Howls, rings and reverbs are easy to create; so are good, old-fashioned solid, rhythmic delays.
– 2 octave, full-width Wribbon keyboard: play piano like a guitar, bending individual notes or entire chords. All without losing fixed-key pitch accuracy when you don’t want to bend. Best of all the whole width of your iPad 2 is there for performance.
– 6 voice polyphony. If that’s not enough (maybe you have tiny fingers), it comes with the best note stealing algorithm on the iPad.
– Modulation matrix: use this to link controls to the Game of Life, or simply use it to define a custom control panel for easy performance.
WOPR is version 1.0.0. It doesn’t yet have these features, but they’re being worked on:
– Audio copy/paste (it’s coming soon.)
– A giant preset library. (More are available for free download within the app.)
WOPR’s architecture might change a bit too. It’s young and has a lot of growing up to do. Right now Omnivore is experimenting with stereo BPF & LPF filters that you can insert into various places in the signal pipeline. We’re looking at ways to drive a wavetable library from the grid, too. Feedback is welcome, so please send your requests to email@example.com.
Finally, what does WOPR stand for? Anything you like. Wave Oscillator Piano Replacement? Wickedly Optimized for Phat Response? Who knows. All we can say is that it’s the synth David Lightman would choose…

About the synth:
The Oberheim OB-X is an analog polyphonic synthesizer first commercially available in June of 1979 . It was the first Oberheim synthesizer that was created with internally pre-wired modules (albeit still mostly discrete circuits) and not with the earlier, unwieldy S.E.M.s (Synthesizer Expander Module). Because of this, it was more functional for live performance, and more portable. It was hurriedly introduced to compete with competitor Sequential Circuits’ Prophet-5, which took the industry by storm during the prior year. While the OB-X had moderate success in the limited numbers produced (aprx. 800 units), the design was quickly updated and streamlined with the OB-Xa; the OB-X being discontinued in 1981.
Originally, the “X” in OB-X, stood as a variable for the number of voice-cards – thus, polyphony – installed. Whereas earlier Oberheim modular systems would require multiple S.E.M.s to achieve polyphony, the OB-X condensed the S.E.M. down onto a single printed circuit board called a “Voice Card”. Using this method, along with the Z-80 microprocessor to program the cards, the OB-X was far less laborious to program than it’s ancestors. It came in four, six, and eight-voice models. The starting price for the base model of only 4 voices of polyphony was a steep US$4,595. Besides the generous polyphony, each OB-X came with a memory capable of holding 32 user-programmable presets, along with polyphonic portamento, and polyphonic sample and hold. Also, a first for Oberheim’s polyphonic range were the “paddle” levers for pitch and modulation. This was Oberheim’s answer to the then standard “wheel” style controls seen on the Sequential Circuits Prophet-5. The OB-X would be used by artists such as Nena, Rush, who used it extensively on “Moving Pictures” and “Signals” Queen, being the bands first Synthesizer to appear on an album Prince, who swore by the Oberheim OB line, and Jean Michel Jarre who used it for it’s massive brass-type sounds. The OB line of Synthesizers developed and evolved even after the OB-Xa with the OB-8, and finally the Matrix series of synthesizers.
SonicProjects have created a VSTi emulation of the OB-X, for Windows and Mac platforms called the OP-X, with near-identical sounds to the hardware version. Widely praised as the most accurate emulation of an Analog Polysynth, SonicProjects include multiple versions of the OP-X including two “Pro” versions.

I am a (proud !) member of the french association PWM (Patch Work Music) :
John from Mungo Enterprises demonstrates a brass patch on the State Zero polyphonic modular. By coincidence someone was rehearsing on a french horn in another room which served as an ideal reference.
The Mungo State Zero modular synthesize is pure digital hardware, but uses a hands-on patch-cord interface. It offers 8-voice polyphony, full patch recall and knobs for everything. When you recall a patch, the knobs turn relative to the saved state, and the saved patch cord state is used until you make changes.
Because it’s a purely digital synth, you can’t patch analog gear into the front panel, but this is supported via rear connections.
Kilohearts lets us know that kHs ONE was not designed to be a fat analog beast with a massive warm sound… that just happened anyway. A spokesperson told us,
“We have put a lot of time and effort into making oscillators and filters of the highest quality which gives kHs ONE a pleasantly warm and analog sound. Working with professional musicians and producers throughout the development process, we have made sure that the sound meets their high standards.”
kHs ONE is available as VST and AudioUnit plug-ins. Both 32 bit and 64 bit versions are available on MacOS X and Windows operating systems.
