JH Triple Chorus and various Stringers |
|
|
Hello, been ages since I posted here last
I've finally got round to building JH's Triple Chorus (better late than never, I suppose), and it got me thinking about various string machines, and I came up with the following, some of which surprised me, but enabled me to replicate them on my Nord G2:
The ARP Omni, doesn't use the standard 3 phase chorus, it's just 3 LFO's, slow, slightly faster and fast (unfortunately I can't find any info on the excact frequencies), each output feeding it's own delay. Example - David Bowie, Sound and Vision
The Elka Rhapsody (490 & 610) has 2 LFO's 0.6 and 6Hz, mixed and phase shifted once (not sure as to what degree the shift is), feeding only two delays. Example - Ultravox's Hiroshima Mon Amour & Cockney Rebel's Come up and See Me.
The Solina, Crumar (Performer/Orchestrator) and Yamaha's (SS30 & SK30 etc), all use the standard 3 phase chorus (as JH's), although Yamaha's SS30/SK30 use two top octave generators, one of which can be detuned for an even more dramatic sound. Example - Ultravox (again!) Astradyne & Magazine's Definitive Gaze.
The one that I can't figure out is the Ensemble effect on the Korg Poly 6... Any ideas?
I just thought it was interesting to know why these glorious string machines sound so different from each other _________________ Kronos 2-88, Kronos 61, Studiologic Sledge V2/SL, Broadwave ARP 2600EX, Broadwave 18U ARP based Eurorack Modular, Broadwave Minimoog Clone, GEM S2 Turbo.

According to JH's web site on the triple chorus:
Quote: | This method creates the famous "Solina" sound, which was so sucessfull that it has been emulated by other manufacturers.
Of these, I have studied two very closely: The Crumar Performer, and the Dr. Boehm Phasing Rotor 78. I've also taken a look at the Korg Polysix's Ensemble mode. |
I.e., the Korg Polysix Ensemble mode IS a 3-phase oscillator like the later Solinas.
Again, from his site (the emphasized "if" in this quote is JH's): Quote: | My conclusion is that if there is a perceivable difference in the sound of a Solina, compared to a Boehm or the Polysix (other than EQ-ing and SNR), this may have to do with these special modulation waveforms.
The Boehm, for instance, has a very direct and precise method of directly creating 3-phase signals. |

I was reading the manual for the Synthoma Elkorus hardware unit-
http://www.synthoma.net It does an analog emulation of the Solina and Rhapsody circuits so one can find some details on the latter.
I'm trying to decipher what's going on in the Roland Paraphonic (RS-505) which contains 3 quite different effects settings and no adjustments other than the choice of which one. It uses 4 SAD BBDs, mono in stereo out. "I" is something like one of the Dimension D modes, not really a string synth ensemble. "II" is a string synth type ensemble. "III" is a crazy stereo spaced out sound that's amazing in stereo but also a sort of take it or leave it effect due to no parameters. |
