I created this polyphonic wind sound on the Roland MKS-80 using the Bitstream 3X to manually modulate the filter to give it a more natural and irregular sounding whistle. I did this rather than using the LFO because although I could adjust the rate the sweep would be automated and too regular instead of being based on human judgement. I am presenting it here in mono with no processing. If I were to use this I would process it in several ways including some volume automation, panning, equalization, probably a bit of slap back delay for stereo imaging, and a fairly short linear reverb that doesn’t sound too roomy.
I accidentally created this pack of cyber wolves on the Super Jupiter. I was dialing in sounds while watching the oscilloscope and getting all sorts of crunchy delights when all of a sudden I was hearing these eerie howls. Fortunately I was recording all along, so afterward I edited it down to the best bits and uploaded it for your enjoyment.
Here’s the forth entry in my series of synthesizer noise jams. Once again I chose the Roland MKS-80 because since I have repaired it I’m spending most of my time programming this magnificent synth. I just can’t seem to leave it alone. Although this segment is almost two minutes long, it came out of a recording that ran over ten minutes.
I created this plucky microtonal patch by using the cross modulation on the Roland MKS-80 to effectively put the instrument into an instable, out-of-tune state. I mentioned in my previous entry that cross modulation is a form of frequency modulation or FM synthesis made famous by the Yamaha DX-7. My curiosity about this technique led me to an article in Sound on Sound from 1994 titled Exploring Analogue (Part 2) by Steve Howell. In the article Howell states,
“…take the output of one oscillator (Osc A) and feed it into the control input of another (Osc B). As the modulation level at Osc B’s input is increased, so its tonal quality becomes progressively nastier. In fact, in the absence of a ring modulator, cross-modulation can be used very effectively to create clangorous bell sounds and the like. But be warned! Because the tuning stability on old analogue synths leaves much to be desired, the oscillators don’t track too well, and a sound that is perfectly tuned on C3 may well have disintegrated by the time you get up to F3.”
On the Roland MKS-80 the tuning stability is pretty good, but it does use VCOs (voltage controlled oscillators), so they won’t track as well as DCOs (digitally controlled oscillators). This imperfection is part of what many of us find attractive about analogue synthesis, and what made it possible for me to produce this bizarre, out of key, yet delightful sound.
This dissonant microtrack was created on the Roland MKS-80 with MIDI mapping on a Korg nanoKONTROL for real time manipulation of the settings. I setup three scenes on the nano to control virtually every parameter, although I was only adjusting a few of them for this recording. What makes this patch so interesting to me are the opposing oscillator frequencies. I managed this by routing the LFO to the VCO and by using cross modulation, which are settings on the MKS-80 that I’m just starting to get familiar with. Everything else on this machine fits snuggly into the subtractive synthesis model, but the cross modulation uses the second oscillator to modulate the pitch of the first. This can be used to produce FM or frequency modulated sounds including bell like tones similar to what the famous Yamaha DX-7 was doing around the same time.
