I have been looking at ESQ-1s for a long time and I was wondering if I should buy one . I use all analogue gear , I DO NOT USE MIDI but the synth looks like it can create some interesting sounds considering that fact that it has 3 digital oscillators . Is it a pain to program ? How well do the filters perform ?

I Have one (in fact 'gurulounger' sold it too me to replace my cz5000 many moons ago.
For a digital s+s synth it can create some wickedly FATTT sounds ,I mean dont pay too much for it but there is a PC editor floating around and it make editing an easy trick it also has a librarian as well so you can save all your patches via midi .One word of warning!!!! My ESQ1 has been updated to ver 3.5 which basically means it has a slightly bigger sequencer memory ..but after a few years gigging it can be a bit unstable live so now it stays at home also because it sits on a stand midied up to my PC the contacts under the keys are filthy (probably) and some keys dont quite work ,allthough this is not too much of a problem since they all ply through midi .....and if I could be bothered I'm sure i Could make them go again ....But it has some awsome sounds in it and you can assign the cutoff to the mod wheel (it has a wheel not a joystck) yeah ....if the price it right (and it should be ....no one seems to know how cool they are ) BUY IT as long as its not too trashed ...cause the likely hood of getting any spare bits is a bit remote.
Also it must be one of the first multitimbral (8 Part) synths that i can think of ...which can come in handy for some exta voices
Can you tell I like mine and I'd never sell it ???
Peace dude

Thanks AJ , I think I will get one . I can't stand MIDI but I have always thought about getting one . I thought since it had 3 oscillators per voice - it had to be fat . I have a MEMORY MOOG but it's a piece of shit the oscillators are NEVER stable but thats normal , no wonder MOOG went out of business .
