Old monophonic synthesizers have had all sorts of ways to sequence notes; from fairly complex programmable sequencers to simple arpeggiation. Arpeggiators are nice because they sequence the notes that are played on the keyboard in realtime, allowing the performer to improvise while taking advantage of the capabilities of the machine at the same time. Based on the speed of the LFO, the arpeggiator on the Sequential Circuits Pro-One will sequence all the notes in a chord in either ascending order, descending order, or both. Other synths offer a feature to play the notes in a random sequence. In this example the notes are played in ascending order. I cranked up the LFO and added some delay so that the notes blend into each other so you can hear the harmony in the sequence. With this technique you can sort of simulate polyphony on a mono-synth.
Analog Arpeggiation
Here’s another sound that I would label as “Pro-One Dub”. I guess all that really means is knob turning and delay, but when you get good results with this instrument you know it. I love the fact that you cannot store presets on old analog gear. It makes you create a new sound every time you turn it on. I had the knobs in a pretty good position to start this time, but after a few more adjustments I got this great modulated effect with the LFO near top speed and at maximum amount. Just tapping a key gave me this nice squirty raygun effect, so I dropped that in the track before getting my sound for the melodic line I needed for the piece. Here’s a chunk of it pitched down a bit and running through a short delay with lots of feedback to create a vintage raygun effect.
Having been asked on more than one occasion, it is about time that I posted a sound from one of my favorite synthesizers, the
