Arpeggio with LFO Routed to the VCF

Here’s another arpeggio from a previous session where I recorded a broad collection of Roland MKS-80 sounds arpeggiated by the Bitstream 3X. What I like about this piece in particular is the way the free-running analog LFO is modulating the VCF. The typical behavior of a digital LFO is to restart the waveform from zero for each new note. However, on the MKS-80 we can hear the continuous, counter-rhythmic pulse of the LFO on the notes as they are played.

Oscillator Sync Mode

I created this sound on the Roland MKS-80 by putting the oscillators into sync mode, then manually sweeping the frequency of the second oscillator as a sequence of notes was played on the synth. This looks like another good example for the oscilloscope.

This composition emerged as I was experimenting with the BS3X and the Roland MKS-80. Usually I don’t title these unpublished microtracks that I share here on ACB, but this one came to me naturally.
