analog monosynth
Here we have a very cool monosynth from the early ’70s, the Davolisint!!!
It is a very compact and relatively light synthesizer, well built to last. It has an unusual design (perhaps the reason for this was to keep cost down), seen that while it has two VCOs (YES!), there are sadly no filters or envelopes.
Let’s do a rundown of the main panel:
From the left, there’s a funky looking lever labeled “EXTEND”. This is a pitch-bend lever, that bends the sound up to one full octave (you pull the lever down and the pitch goes up, go figure) It is a very useful features and allows the typical 1970s synthesizer expression. It is spring loaded and it returns to its original state, somewhat more slowly than we are used to have pitch benders return, these days.
Then there’s a set of seven white rocker switches labeled 32 to 1/2. These are simply the footage switches for the basic waveforms (similar to an electronic organ). You can have them all on at the same time, or mix and match as you please.
In the middle of the panel there are six sliders: the first controls the VCO 1’s pitch (fine tune, up 1 tone, down 1/2 tone); the next four control the vibrato frequency and intensity, independently for both oscillators. Then there’s VCO 2’s pitch slider: this offers a larger pitch excursion than OSC 1, going up one full octave, and down almost one octave (great for those detuned Moog-like synth lines).
To the right of the panel there are seven more white rocker switches: the first one turns on VCO 1, the second and third switch on vibrato and portamento, respectively, for VCO 1 (portamento is indicated with “T”). The fourth is the portamento switch for VCO 2. Then there’s a switch called simply “C”: what it does, it simply turns on the lowest C on the keyboard (on the white keys), to obtain a drone. Why this is, I have no idea. Maybe to tune the other instruments of the band? After the “C” key, there’s a rocker switch to turn on vibrato on VCO 2, and finally a last rocker switch to turn on VCO 2 itself.
A big red switch concludes the front panel. All the switches and sliders are clearly labeled with their functions.
NOTE: The keyboard only offers two octaves (the white keys). The grey set of keys (one octave) to the extreme left is simply a set of keys that act as momentary switches for the same controls that are being offered via the rocker switches. This is probably to offer the performer a more ample range of expression – i.e., it’s easier to engage the portamento momentarily, using the grey keys, and more expressive than just turning the rocker on the whole time. Well, this is also debatable.. I would probably have preferred another octave to play, rather than having this basically – repeated – set of controls.
Yes, but how does it SOUND??? Well, scroll down to hear examples from this Italian beauty; it actually sounds pretty good! While the main character is simple, the tones achievable and certainly fat, very expressive, and quintessentially ANALOG. In certain settings, and with the right technique, you can even achieve a Minimoog-type sound, and that’s a BIG compliment!!! Of course, this is a lot simpler than a Mini, but if you can’t afford the old faithful, this is a fun alternative!

Digital programmable algorithm synthesizer
The most famous synthesizer of the 1980s.
Its electric piano became a standard sound in ballads and “smooth jazz” genres. Its bass was the standard bass sound, typically played in bouncy octaves. Its crystalline timbres were such a departure from the world of analog, that this synth was a super-hit for Yamaha in 1983, and spanned a long family of FM-based products.
The DX7 came out in 1983, sporting the new MIDI interface. The high quality of its digital sounds, velocity + aftertouch, the expandability, the thoroughly professional look, and the complicated programming interface, made the DX7 and FM synthesis take off in a way the was unknown before for synthesizers. Thousands of units were sold, and thousands of records have that distinct DX7 sound (especially for the electric piano, the bass, marimba and glassy, crystal-type sounds).
The DX7 was also the first synth that originated a huge “patch creation” business. Since it was cumbersome to edit, many programming houses were established, ready to feed the hunger for new sounds that players all over the world craved. Today, there are literally thousands of sounds available for the DX7.
Bottom line: together with D-50 and M1, the synthesizer of the ’80s

Digital/Analog synthesizer
This black beauty is one of the many semi-unknown Italian synthesizers of the ’80s. It is a typical digital/analog hybrid, sporting two DCOs, VCF, VCA, and two LFOs. The programming on this synth can be a little cumbersome – it was the era of knob-gone digital after all… so programming is similar to other synths of the time: a keypad to change the parameter, and two up-down buttons to alter the value of the parameter dialed. The parameter list and flow diagram are stenciled on a large graphic in the middle of the front panel.
Several keyboard modes are provided; you can split the keyboard, or layer two sounds (double). There’s even a very cool Unison button that makes for some excellent, fat sounds. The pitch and mod wheels are above the keyboard, and on top of each other, as opposed to a more traditional side-by-side – for this reason, the Bit One is a nice, compact five-octave synthesizer.
The Bit One is a “stereo” synth, providing Upper (left) and Lower (right) separate outputs. The notes will come out of each channel at random. I’m not sure if it is a problem with my machine in particular or if all Bit Ones are like this. Best to stay in mono (Upper) if you don’t like the resulting effect.
There are four two-character displays: (parameter) value, address (the parameter selected), Lower Prg and Upper Prg. A compare button is also provided.

The Cruise is what was once referred to a “multi-instrument” keyboard, that is a synth having two or more sections designed to emulate a particular instrument, i.e., brass, strings, bass, organ, piano and so on.
They were popular in the early 80s, and other examples of this breed are the Crumar Orchestrator, the ARP Quadra, and the Korg Trident.

Let’s listen to the well-programmed DEMO SONG – “Night Birds”, by the British group Shakatak (thank you Vincent de Mulder for the tip 😉 ) – showcasing the best sounds of this module. Melodically, I really like this song, especially from 1:06 to 1:20 and similar, where the classic “Autumn Leaves” harmonic progression is employed to great effect. The piano is realistic enough – for a module of this era. And the crowd really liked the performers! 🙂
