Yom Kippur 2017, Meditations and Reflections

Star of David

Fast, reflect, and question. These are our personal mandates on Yom Kippur this 5778 (2017). Fasting is pretty self-explanatory – I don’t do it every year, but this year it feels important to do so. Sam Sam does not have to fast. The questioning centers around “what does it mean to be Jewish in this time and place”, an especially complicated and treacherous question for those of us who are secular Jews. Yom Kippur is described in Leviticus, the one book of the Torah that I have not been able to get through in its entirety (mostly because it’s extremely dense and about as riveting as the phone book). But I still celebrate independent of that, based on heritage and family tradition. You are a Jew if your mother is a Jew, end of story. I extend this rule to my cats.

For an excellent read on the topic of secular Jews on Yom Kippur, especially secular Jews committed to activism and social justice, please read this article by Dania Rajendra [Full disclosure: Dania is my sister-in-law.]. For me, part of my plan for this holiday was to compose a track based on sounds from a short-wave-radio synth module an, idea I formulated during a reflective moment last night.

The track was recorded as a meditation of sorts, getting into a heightened, focused state while turning the knobs of the Eowave short-wave module, tuning into stations that aren’t there. The other “master” of the track was the Wiard/Richter Noisering, which I let control the Rossum Electro-Music Morpheus module. Both focus on chance and working with elements very much outside my control. I also did not want to spend much time outside the meditation-recording process itself. There is no editing save for some tapering at the beginning and end of the track and the obligatory EQ and compression.

I am both doing too much, and too little at the same time. I can’t save all the shelter cats; I can help everyone suffering through one disaster after another in North America and Carribean. But I can try to make a little bit of a difference in each. When I focus on all things “CatSynth”, sometimes my music suffers – I’m overdue booking new gigs for my band CDP and I do feel a need to atone for that. In short, the challenge in 5778 and beyond is to find a way of doing all the things that matter most while minimizing time and resources on the things that don’t. No easy task for someone who tends to say “yes” to everything, hates to disappoint others, and has a difficult time letting go of things. But that last one is another aspect of this holiday, and so it is as good a time to begin as any…

Rossum Electro-Music Morpheus and Other Modules

Last year, I was excited to see the debut of Rossum Electro-Music. This year, the excitement is that the Morpheus module will finally be available soon.

Since our picture, although appropriately cute, isn’t the best, here is an official image.

The Morpheus module features a 14-pole Z-plane filter similar to one in the classic E-MU Morpheus (which I still use in some of my music), but goes beyond the capabilities of the original. As it is a module, one can use any sound source with it rather than just built-in ROM samples. And all the the dimensions of the filter – which are visualized as a cube – can be manipulated in parallel from arbitrary CV sources. On top of that, a step sequencer allows one to move through different configurations of the filter in real-time.

I was only able to scratch the surface of the sound possibilities with this. One thing I’d like to explore is whether with all the degrees of freedom this filter is even more unstable than the original. That’s not a bad thing per se (as long as one has a limiter handy), as it can be a thing of beauty to bring a filter just to the edge.

The Morpheus is actually part of a full suite of modules that Rossum Electro-Music is offering. The Evolution ladder filter was already debuted last year, and is a fine filter in itself. There is also the Control Forge CV generator, Assimil8or phase-modulation sampler, and Satellite CV generator. It occurs to me that putting these modules together (plus a MIDI to CV converter) one could theoretically construct an “E-MU Morpheus on steroids”.

We at CatSynth shall eagerly await the public release of the Morpheus in the coming weeks and keep an eye out for things to come from our friends at Rossum Electro-Music.

We at CatSynth have long been fans of E-MU Systems’ synthesizer. The Proteus 2K and Morpheus remain vital parts of my music studio – and some long-time readers may recall that I used to work for E-MU many years ago. So it was excited to see the new Eurorack modules from Rossum Electo-Music, the new project of E-MU founder and synthesizer inventor Dave Rossum.

The main module available is the Evolution, a Moog-style ladder filter with some unique twists. It allows the user to switch among topologies, from 3 to 6 poles, in real time. And of course this function is controllable via CV for some interesting effects. The filter itself sounds great, with signal conditioning to allow resonant sweeps while maintaining strong bass tones from the original signal. The Morpheus module is a Eurorack implementation of the legendary E-MU Z-Plane filter, which allows interpolation on three axis between different 14-pole filter configurations. All of the parameters for the Z-Plane filter are CV controllable. Unfortunately the Morpheus wasn’t ready for me to hear, but I certainly looking forward to it.
