Underrated Workhorse

An absolute classic bit of kit that's supremely underrated. Capable of doing a solid imitation of lots of your standard analog polysynth sounds, but so much more on top of that. The synth has absurd modulation capabilities for something of its era, with 4 Envelopes and 3 LFOs that can be routed to almost any parameter. The oscillators are classic Ensoniq transwave synthesis fare, but paired with an analog filter you get some pretty lush sounds. The sequencer can be fun, and with good sound design and judicious use of the 8-voice polyphony, this keyboard can serve as a rudimentary groovebox.

The thing I've used my ESQ-1 for the most is as my master keyboard. Not only do the keys feel great (though they're not weighted), but this is one of the few keyboards I've found that actually transmits midi note off velocity!

jimmarchi1

arcane user interface? GET OVER IT

The thing I love about the ESQ-1 is that its a traditional subtractive synth hiding in 80s digital wavetable skin, a wolf in sheep's clothing, that REALLY takes advantages of its digital 'brain'. Once you wrap your head around the user interface you can assign ANY parameter to MIDI note velocity. WHAT?! Yeah. I wish it had a better keyboard, but I tend to use it as a module. I like to play a line into Fruity Loops on a nice weighted key controller being sure to really syncopate my attack and then assign that sequence to a MIDI channel that's commanding the ESQ-1 and dial up a patch where filter cutoff or resonance is controlled by velocity. For extra fun I like to crank the audio out thru an ac30, mic her up and hit record. I really enjoy some of the interesting wavetable snippets that the DCOs on this bad boy generate. Blending, say, the piano snippet with a straditional sine or square is really neat. There's a lot of cool percussive sounds in the liabrary. This thing is capable of a lot, but it just doesn't have the kind of hands on control dance musicians expect, however, once you realize its a PERFORMANCE synth designed for guys who play piano and organ and that the ability to create motion and vary texture in your sounds can be PERFORMANCE DRIVEN you will unlock the keys to the kingdom so to speak. These synths aren't worth spit anymore, I don't know why. Buy one and get playing. Even if you're a mediocre pianist like I am you can always record MIDI data and lock to grid to create insane sounding lines. Also, the DCFs are harsh and squelchy in a totally un-vintage (as in un-moogish) way that reacts really great to analog distortion both tube and solid state. Get over the learning curve and you will be able to make really amazing music with this diamond in the rough. This is another highly underrated synthesizer from the good folks at ensoniq.

Thanks for this! Ive been thinking about getting an Ensoniq synth for a while now. Only Im not sure which model to choose.

jimmarchi1

the sq8L is superior ina ew ways and they go for about the same money.... I picked this synth up ages ago, impulse buy from a pawn shop when I was new to electronic music ;-) She was a fairly new piece at the time and was much reviled as modelling synths loaded with knobs and full-scale workstations were the hot items back then! It took me a LONG time to really delve into this synth, but once you get used to the weird envelope and routing menu structure it gets easy to make great patches that run the gamut from DCO type analog to FM/CZ/wavetable type stuff

also, the analog filters are Curtis chips on both the esq1 and sq8L... worth about $400 I would say

ron_tyili

my dads mate had one of these growing up.. no sure what happened to it

Spend a little time with it and you won't be sorry.

The ESQ-1 is what I call the "quiet achiever" of the 80s digital synth market. Yamaha brings out the game-changing DX-7 (replete with that godawful electric piano sound which found its way into far too much radio-friendly tripe).

And then about 5 years on, Roland says "Okay, our turn! Cop this" and releases the D-50. Both with their positive and negative points, the DX-7 was probably the most user-unfriendly synth available (one J.M. Jarre reports it as being "a pain in the arse to programme") and the D-50 perhaps tried a little too hard with some new lingo ("Linear arithmatic" "partials" etc).

Meanwhile, without any fuss, Ensoniq brings out an absolute charmer in the ESQ-1. 3 digital oscillators (osc sync, FM, and ring mod available) each with 32 waveforms, some analogue, some sampled. A ton of modulation possibilities with 3 LFOs, 4 6-stage ENV generators, each freely routable to practically any parameter.

An analogue resonant filter. Velocity sensitive keyboard. MIDI. A large display with dedicated buttons to access each section and parameter (compared to those other two - easy!) Oh yes, and an 8-track sequencer ... I mean really, we're getting into workstation territory here (minus effects though).

What's not to like?

Has a Rare Quality: Versatility at Both Digital and Analog Sounding Patches

In respect to my own use, the ESQ-1 can cover some of the same territory of both DX-7 FX & bells and middle-of-the-road resonant analog pads of synths w/ DCOs such as the JU-06 or Poly 61. While it doesn't sound huge or high fidelity by itself, the ESQ-1 sounds great in a mix and is a great songwriting companion as it covers a ton of territory with an unassuming interface that doesn't distract from building solid progressions and melodies. I don't give it a 5 because it commits the sin of having neither an accessible knobby interface, nor a good MIDI implementation. Useful CC messages are not-existent and the only ways to access a filter|OSC|LFO during performance are the mod wheel and a single "XPARAM" which is the Ensoniq parlance for assigning a single CC message number to a single global internal parameter such as filter frequency or an ASDR level.

jimmarchi1

I tend to PLAY mine. Iy shines as a performance piece for complex parts where you need a polysynth that can be programmed to respond to your dynamics a little. From what I understand the SQ8 really improves on the ESQ1s MIDI implementation and fixes the few performance bugs.... but tweaker's synths they are not, definitely performance pieces like the DX7, M! and pretty much ll of its digital cousins....

I've flirted with getting rid of mine so many times but every time I think I will sell it I wind up performing a part on it that no other synth will cover. I admit tis a bear to program patches that take advantage of its capabilities, but it ahs a sound in the mix that's not really like anything else unless you want it to be.

mikefiction

Close to Perfect

This is the only synth to survive the studio purge. I've had it since 2001 or so and know it intimately. It gets cranky and I have to open it up occasionally.

Mine is made of metal. It's made in the USA. It's analog and digital. It is the best.

It makes me laugh like those girls laughing at salad in those stock photos every time I use it.

deepsignalstudios

Very underrated

Expressive as any highly coveted VCF poly out there but you can always find it for a few hundred bucks. Programming it, on the other hand, is not too fun. There are thousands of patches floating around the net so if you get one get a librarian app and listen to all of them and you are bound to find something great to use.

jimmarchi1

yeah, she's a bear to program, but once you get the hang of it? wow

thomashaahr

Good unique sounding synth.

Good sounding filters - quite easy to program and can make some interesting sounds, especially if you're into ambient stuff. Looks nice, but weighs a ton...

Note that she indicates this was borrowed from producer Benge, so it's a small stretch to include it in her list of gear. But as it played an important role on the record, it seems fair to note it.

From the Tendon Levey website:

” In the month of February 2009, while rummaging through my basement, I came across my father’s old Ensoniq ESQ-1. I was totally unaware of its existence and I couldn’t understand why there had been no attempts to dig it out previously. With my previous synthesizer having died back in 2008, this ended up being a big deal to me. I was totally in love with this keyboard. It seemed endlessly customizable and I could get all sorts of weird sounds of it. I played it until it gave out on me five months later during the recording of Evil Guest List. I was devastated and spent the autumnal months attempting to make up for the lack of a keyboard with new guitar techniques and effects meant to mimic a keyboard.”
