Ethereal voices

I've been trying to get another post up here for the last week or so, but something always interrupted me, so here's a go at a quick e-mail post from my mobile phone.

Basically, we recently invested in an iMac, partly to retire our old PC which is getting rather long in the tooth, but also for producing music and some graphics (the latter mainly for Joy's music activities for children). I bought Logic Express to go with the machine, and have been experimenting with it to add an extra dimension to our music production.

Yesterday evening I finally got to try one of Logic's software synthesisers that I've been dying to have a go on: EVOC, a vocoder synth (which blends the synth signal with an audio input such as a voice). In a nutshell, I was recording some guitar synth parts for "When The Sun Goes Off To Sleep", a song for the "concept album" (which I'm still hoping to finish this year, honest!), and decided to add some 'vocoded' voice to the end. The song has been around for a few years (I wrote it as a lullaby for my daughter), and my original acoustic demo dates from late 2004, but I've wanted to re-record it to give the song a more ambient, dreamy air. In particular, I hoped Joy might sing a bit on it, as I had conceived a female vocal sound for the ending, but she felt a bit shy and backed out, so the idea was shelved until I thought of using Logic's vocoder (which might capture even better the effect I wanted).

So, last night I recorded the voice part for the vocoder to use, set up the MIDI guitar and played the melody on the vocoder. The results were just what I was looking for—an ethereal 'voice' (or 'voices', as I'd played a 'chordal' part into the vocoder), floating behind the lead vocal in the final verse. I also tried my original idea for the song ending: two lines from the Korean nursery rhyme which gave the song its chorus melody. This worked pretty well too, so I think you can expect to hear all this on the final version of the song, when I get around to putting out the album.

The moral of this story: vocoders are fun :-)
