Synthesizer Spotlight- The Synergy

Leave a comment

The Somewhat DX7 Like Alternative

The Digital Keyboards Inc Synergy II+  is a digital additive/FM synthesizer that sounds like no other. Somewhat similar to the extremely popular Japanese Yamaha DX7, its tone is mellower and warmer. The Synergy appealed to many performers and composers in that it was, like the Synclavier (one of Michael Jackson’s famous early synthesizers) , made in USA.

It’s estimated that only 700-800 Synergy keyboards were made and that less than 100 are in operation today.

Due to it’s rarity and lack of many working examples, it is not easy to garner modern day opinions and user experiences and so it makes sense to paste some stuff from wiki:

“Analog synths of the same era (the late 1970s and early 1980s when the Z-80 computer chip ruled the electronic world) were subject to environmental changes in the input controls that meant every performance, even after a short delay, would be different. The tuning capacitors would drift due to performance venue temperature changes or recording studio humidity and temperature changes making it very difficult to stay in tune with other instruments and especially other electronic instruments.

One way around this was to spend huge sums of money on the latest high end digital synthesizers that held their tunings digitally. Famous electronic artist Wendy Carlos (her originally soundtrack for The Shining remains unused to this day and I have yet to hear it. If you have a link please share in the comments below) owned a Crumar General Development System, or GDS, that was released in 1980 and sold at that time for $30,000USD / $41,544 CAD or $114,300 USD / $158,271 CAD in today’s prices after adjusting for inflation . “

The GDS was used famously on the Tron soundtrack.[9] She was also one of the instrument’s most devoted users, and still uses it to this day.

The GDS Leads to the Synergy

With microchip prices falling including the Z-80 and with further work on the same basic concept of the GDS (additive synthesis, a system microcomputer, programmable sound generators, and a number of different input devices) the lower-cost Synergy was released in 1981.[10]  More affordable and more powerful computer chips meant that The Synergy was able to remove earlier expensive design parameters that would have required a separate stand alone computer component, and re-packaged the entire system into a case with a 77-key keyboard.

Due to it’s high price, the GDS did not sell well, allowing the Synergy to find some market share. However, when the famous Yamaha DX7 was released in 1983, it quickly took over the market. The DX7’s FM synthesis offered the same basic control over output sound as an additive synth, but could duplicate the effects of many ganged oscillators in as few as two.[11] Its $2,000 usd/ or around $7,000 usd in today’s money when adjusted for inflation. This price point eliminated any competition from the additive synths and production of the Synergy ended in 1985.

Mulogix Slave 32

A final version of the original Synergy machine was produced after Digital Keyboards was shut down in early 1985. More on this below. Digital Keyboards’ chief designer, Mercer “Stoney” Stockell, decamped and formed Mulogix with Jim Wright and Jerry Ptascynski. The Mulogix Slave 32 was a Synergy re-packaged into a 2U rack-mount module with a MIDI interface. The Slave 32 could read and write EPROM cartridges from the Synergy.[12]

Final Version

Later models of the Synergy, known as the Synergy II+, feature MIDI implementation, 24 user voice RAM, and an RS-232 computer port. This allowed support for Kaypro II portable computer systems running Synergy voicing software to open up the possibility to finally edit the sounds of the Synergy as well as to save patch and sequence data on to floppy disk.

A Quest To Lost Arts In Chicago To Build My First Hyve Touch Synthesizer

2 Comments

I started out creating sound experiments while in high school, circa 1980 with circuit bent hardware and a cheap Casio keyboard.

I then entered the working world and forgot all about making music. Fast forward 30+ years, and the itch to make experimental music overtook me again, but now technology had changed drastically. I no longer needed hardware. I discovered apps on my iPhone, and music platforms like SoundCloud and Bandcamp were all that I needed. I was immediately obsessed.

Within a couple years, I had filled over seven free SoundCloud accounts, and two Bandcamp albums  as well as an artist page  with experimental music, and having a great time doing it. But, I started to grow tired of using the same software.

stylophone synthI yearned to use hardware/instruments again, but not being able to play an instrument is a definite hindrance 🙂 I searched for cheap keyboards on the net. I soon discovered the “Stylophone” and ordered one ‘sight unseen’. It was unique, inexpensive and fun, but quite limited in sound variety. I started mixing the Stylophone with app produced sounds/music, as well as other “found sounds”. (I really appreciate the functionality of software based mixing apps, which are almost essential to my creations these days). I then stumbled upon a couple of user videos of the Hyve synthesizer, and knew I had to have it. It was clearly non-musician friendly (and looked so different, cool and fun).

Then came the disappointment … You can’t buy one! (BUT I HAD TO HAVE ONE!!!) Turns out, the engineer/designer guru behind this awesome device (Skot Wiedmann), has work shops in the Chicago area, and you can go build your own, ( very inexpensively ). I knew what I had to do. I looked at a map, saw that Chicago was about 8 hours away, and realized that I had to go build it. I started to plan the trip. I knew that a fellow SoundCloud musician and Facebook friend (Leslie Rollins) lived in Berrien Springs, Michigan, about 2 hours outside of Chicago.

This presented a twofold opportunity. I could hopefully, meet Leslie face to face, and hopefully have a place to spend the night. I contacted Les and everything was A-OK! I purchased a ticket to build my Hyve, and started to plan my road trip. The workshop was going to be from Noon to 3pm, Saturday Sept.24 in a cool space called Lost Arts in Chicago.

I had the whole week off from work, because I was overseeing a contractor doing extensive yard work at my house all week, and I was hoping to leave Friday so as to arrive at Leslie’s place in the late afternoon or early evening, spend the night, and leave for the workshop Saturday morning. Alas, plans rarely work as hoped.

The contractor wasn’t finished until Friday afternoon, and Les wasn’t getting home from a business trip until late Friday night.
New plan! Early to bed Friday. Early to rise Saturday (2:30 am), and depart for Leslie’s place in Michigan. It was an easy drive, and I got to Berrien Springs (a beautiful sleepy little university village) around 8:30 am. Met Leslie, and got to trade stories over a great breakfast in a local cafe. Then, I quickly admired Leslie’s impressive modular synth racks at his home studio “Convolution Atelier” and then left for “Lost Arts” in Chicago.

Lost Arts is located in a cool old industrial complex. The workshop provided everyone with a surface mount board with the touchpad on one side, and components layout on the back. A sheet listing components and placement was also handed out, along with tiny plastic tweezers. Everyone then had their component side “pasted” with a solder paste applied through a pierced template, in a process similar to silk screening. Everyone then started to receive their very tiny components from the parts list. Following the placement locations, the components (chips, capacitors, resistors, etc) were set into their pasted areas with the tweezers (magnification and extra lighting was a must). Once all the components were placed, they were carefully “soldered” into place by simply holding a heat gun over each component until the solder on the board had adhered it. Once this was done, everyone had their 9v battery and line-out jacks hand soldered into place by Skot , and then … the moment of truth, Skot tested each one for proper operation.

It was a fascinating process and great experience. I met a lot of cool people at the workshop, both builders and staff/helpers! I can’t say enough what a fantastic experience this was, and what an awesome, diverse and versatile device the Hyve is. I doubted my sanity when planning this trip, but it turned out to be very rewarding!

Leslie and I then went back to Michigan, stopped at a local brewery in Berrien Springs (Cultivate) and sampled a few of their excellent brews, and then proceeded to Convolution Atelier to play with Leslie’s modular system. (I’m a newbie to all things modular, and I received a great crash course from Leslie on his very cool array!) Then it was out to dinner with Leslie and his wonderful wife Lisa, and finally back to their house where I stayed for the night, and finally hit the road towards home the next morning. It truly was a great adventure! For the Silo, Mike Fuchs.
