While reviewing my set for last night’s Ostraka performance, I noticed that using filtering followed by down-sampling produced a robotic vowel like sound applied to synth bass. It’s got a nice vintage vocoder or Speak & Spell graininess to it.
Finding this effect was really an accident, because I had been using this particular effect chain on my master track in this set for a while, but hadn’t stumbled across the settings that produced this sound until last night. Placing the filter before doing the the down-sampling is the key. It does not work the other way around.
Here’s a couple of minutes to illustrate how to apply the effect. I was making real-time adjustments to the frequency of the low pass filter, and the amount of down-sampling. Toward the end I upped the reverb to give it some tail.
