Logan Vocalist *Soundgas Serviced*

One of the rarest synths on the planet – the Logan Vocalist uses two ingeniously set up oscillators per voice to create haunting human voice-type sounds.

NOTE: This synth is tested and working but will be serviced by our head synth tech James Walker before shipping. It will ship within 20 working days of purchase.

Logan Vocalist for sale. This is a unique-sounding instrument, as full of character as a Mellotron choir, but far more expressive due to its wide-ranging real-time tweakability.

The Logan Vocalist has richly chorused Tenor and Soprano choir, and the purer solo voice (switchable to tenor or soprano) which can be played simultaneously with up to 6-note polyphony. The unique design of the voices features two cleverly set up oscillators (not formant filters as we initially believed – see below for more on this) and allows them to adjusted to create different vowel sounds. Vibrato depth and speed of the solo voice can be tweaked in real time for a very effective human vocal sound. Nice switchable voice triggering: you can have the top note of each choir chord playing the solo voice all the time – or your right-hand can play the solo voice independently over choir chords in the left hand.

Voice Architecture on the Logan Vocalist:

Dani Wilson of Hideaway Studio very kindly sent us this:

The Logan Vocalist is not strictly a formant synth – it has no formant filters as such… (I looked into the architecture of this k/b for Soniccouture last year and took raw audio from various points along the signal paths).

It is actually a rather ingenious design (as were many of the Italian synths of the era) and utilises two oscillators per voice (it is voice allocated, not a divide down like many vocal/string synths) – one osc hard syncs off the other.

The vocal effect controls are actually implemented by setting up a sweet spot in the range of the osc sync level which covers more vocal timbres – if you were to go outside of this sweet spot the vox effect would be completely ruined.

So all in all its a very clever design that doesn’t have to rely on a ton of analog formant filters (for example like the Polymoog) to achieve a vocal effect.

NOTE ABOUT DAMAGED END PANEL:

One end cheek is pretty chewed up – it doesn’t look too bad from the top but from the rear it is not great. We can get our man of many talents Chris to make a replacement while the synth is being serviced. It will be the same shape and similar colour (but without cutaway detail at the bottom). The cost will be an extra £60+VAT. If the buyer wishes us to make two matching end panels instead then we can do that for £100.

CONDITION: In very good overall condition. The face is clean with only minor signs of age. The end cheeks are scruffy and have sustained some damage towards the back corners, this has previously been repaired [see note above about option to replace the panels]. See photos for more information on cosmetic condition.

220/240v unit. A step-up transformer will be required for use on 110/120v supplies. Please ask if you need advice on what to use. We do not recommend using cheap, generic Chinese mains transformers.
