As I am about three fourths of the way done with my next album and my studio is a mass of wires. I’ve become obsessed with syncing my old drum machines and analog synthesizers using various methods. I’m not looking for perfectly quantized MIDI. I’m looking for some Control Voltage madness. Last night’s experiment will definitely make it to a full song. I haven’t shared anything with you in a while with regards to my upcoming music but it’s time I start breaking the ice. The audio sample may not be your cup of tea but the method can be used to create all sorts of nonsense in many music styles.
I have an old Korg Rythm 55 drum machine. I go out of it’s Trig Out to a Doepfer Dark Time analog sequencer’s Click In. On the Korg you can set the sequencer to trigger in various times. If you select a 16th note you will get your typical Giorgio Moroder type of thing. This time I have it set to follow the Korg’s kick drum (blue arrow above). The Doepfer is hooked up to one of the oscillators on an Analogue Solutions Telemark synth (both pitch and filter). This time around I don’t want the Dark Time telling the synth to play different notes. I only want it to Trigger a very slight pitch change and that’s why (see the green arrow) I have the pitch line stop after the second step. The two steps are just slightly detuned. The filter does change open and closed over 8 steps (which you can only hear when the filter is partial closed at the beginning). If you notice there is a grey Midi cable plugged into the top of the Dark Time. If I wanted I could play different notes on my attached MIDI controller and the entire sequencing line would change pitch.
Hit play on the Korg and off we go. I turn up the filter, bring in the Korg’s snare and you have something from a different decade. To add to the whole vintage feel the Korg has some Boss DM-100 on it. You can hear when I hit the fills on the Korg the synth follows and it’s really magic. One last thing to note is if you look at the Analogue Solutions Telemark photo above you see that orange arrow? That points to the other oscillator that’s not being controlled by the Doepfer. Its another reason you hear a detuned sound. I can bring it and the noise knob in and out for great effect (or verse/chorus parts). Time to add the vocals.
“At its most basic, an analog sequencer is nothing but a bank of potentiometers and a “clock” that steps through these potentiometers one at a time and then cycles back to the beginning. The output of the sequencer is fed (as a control voltage and gate pulse) to a synthesizer. By “tuning” the potentiometers, a short repetitive rhythmic motif or riff can be set up.” – Wikipedia
