I remember when the Morpheus came out, I read the descriptions and thought it sounded fascinating, though a bit of fiddling with one in a store was completely underwhelming. Since then Iâ€™ve occasionally wondered:
- How does the Morpheus really sound?
- Can it do things no other synth can do?
- Do later â€œZ-planeâ€ synths carry on its essence?
- Is it worth having one today?
Luckily, I got to borrow one for a few weeks, enough to get some decent answers, though I donâ€™t claim to be a Morpheus expert. Here are my basic observations, which Iâ€™ll go into in more detail below.
- It may have the worst presets ever created. They are almost uniformly muddy, cheezy, boring, and/or unrepresentative. They provide essentially no information about the sound of the synth.
- The annoying button-mashing edit UI isnâ€™t really that bad. Sure, itâ€™s not great, but itâ€™s at least linear and the synth is not that complex. If you otherwise like the Morpheus, the UI isnâ€™t really going to hold you back.
- For such a sophisticated, nerdy synth, itâ€™s surprisingly limited. The set of things you can modulate, particularly in real time, is limited. The handles you have for tweaking the wondrous 14-pole, Z-cube filters are disappointingly few.
- There are truly some interesting options among the 197 filters, though more than half I donâ€™t see ever using, a number of the rest Iâ€™d use only rarely.
- I honestly donâ€™t think anyone, even E-mu, has really created filters like this before or since. You could try to recreate them in a virtual modular, but it will
get very complicated.
If you want the spoiler: in my opinion, while the Morpheus has some interesting, unique capabilities, enough to inspire some serious sound design, itâ€™s too frustrating overall due to its limitations. If E-mu had updated the Morpheus (Morpheus-2000!) with more power and flexibility, it could have been an amazing synth, a true classic. I doubt I’ll ever get one of my own (unless I find a real bargain), but I’m already taking inspiration from its filters into virtual modular designs. Now on to the details.
First, let’s get right to a demo. This is a very basic patch that runs a sawtooth through a sampling of the filter types available. I’m tweaking knobs mapped to the three main filter parameters: morph, frequency tracking, and transform2. On a few of the patches, I’m also modulating the morph position with a short decay envelope and/or a random note-on S&H. Each filter goes for 16 measures (30-35 seconds).
The Morpheus has a fairly typical rompler architecture: each patch is composed of two parts (â€œprimaryâ€ and â€œsecondaryâ€; most romplers seem to go with four), each consisting of a sample oscillator, a filter, and an amp, modulated by envelopes and LFOs. In most romplers, these parts are almost completely separate, but in the Morpheus theyâ€™re a little more integrated, sharing LFOs and aux envelope (independent amp envelopes) and a single modulation matrix. The Morpheus also offers two â€œfunction generatorsâ€ per patch, essentially an 8-stage envelope, with some crazy extras. One caveat: the LFOs seem to always retrigger at note-on, ruling out slow sweeping filters on fast arpeggiated synth lines. Furthermore, they donâ€™t seem to do the â€œrandom value at note onâ€ trick properly either. Aside from the standards, there are four MIDI CC sources available, set globally. Many modulation destinations can be for the primary part, the secondary part, or both. There are plenty of modulation slots, but the matrix is somewhat limited in that some destinations (particularly filter params) canâ€™t be modulated in real time, only at note on. I generally like E-muâ€™s realtime/note-on distinction, because it makes it very easy to do some nice per-note effects, but of course I want more real-time options. The Morpheus is mostly comparable to romplers of the time, though a little less complex simply in number of layers and programmable parameters.
The samples are pretty good. For non-romplery synthesis, thereâ€™s a decent collection of basic waveforms and synth waves. Given the existence of the UltraProteus, I think they could have just tossed most of the real instrument samples and put more synth waves in, but itâ€™s fine. The Morpheus does offer a few wave options you donâ€™t often see: you can turn looping on or off, reverse the wave, and offset the sample start (though you canâ€™t modulate it). You can also â€œdouble + detuneâ€ each part, which I assume plays a second copy of the same wave, detuned (halving the polyphony), which is handy.
But of course weâ€™re here for the filters. The basic idea is that, with its 14-pole filter dealie, the Morpheus can offer all kind of filters from simple 1/2/4-pole low/high/band-pass filters through flangers, comb filters, and EQs to complex networks of bandpass filters tuned to formant frequencies. Furthermore, the Morpheus can morph seamlessly between these different filter types. The most Morpheusy of the filters involves a â€œcubeâ€ where three dimensions of modulation can morph among the 8 filters at the â€œcornersâ€ of the â€œcubeâ€. In theory, this is pretty great, but in practice the Morpheus doesnâ€™t give you control over all of this. Each of its 197 filter settings is an assignment of various filter types to the corners of that cube, and all you control is those three morph dimensions (called, confusingly, â€œmorphâ€, â€œfrequency trackingâ€, and â€œtransform 2â€). That is, if youâ€™re morphing between a low-pass filter and a high-pass filter, you donâ€™t get independent control over the frequency, resonance, or slope of each of those filters, just the morph position between them. Typically, in a setup like this, the second dimension might control cutoff frequency while the third controls resonance; but not necessarily. Many of the 197 donâ€™t use all of these dimensions â€” some of the 8 corners are identical – and in many more the corners are fairly similar so that one or two of those dimensions donâ€™t change that much.
The final blow is that only one of these dimensions (â€œmorphâ€) can be modulated in real time; the other two are note-on only. This means that you canâ€™t, say, hold down a note and turn knobs to morph that sustained note all over the place, which pretty much kills the â€œIâ€™m going to make an ambient track with one finger like on the Wavestationâ€ vibe. In fact, you get the most satisfaction out of sending the thing a rapid arpeggio run, where you can tweak all three filter dimensions at note-on with knobs to get some nicely varying sounds (though you canâ€™t do slow LFO sweeps). My assumption is that by the time they implemented these insane filters they had no processing power left over to compute realtime modulation, which is why a modern revival of the Morpheus could be so great. Too bad E-mu is no longer around.
Again, donâ€™t even pay attention to the presets. Many of them are kind of weak and muddy-sounding, which does the Morpheus a disservice. Depending on the wave and filter settings, the Morpheus can sound quite strong and full, though of course many of its more distinctive sounds are weird vowel-like or strangely filtered sounds that you wouldnâ€™t use for techno-bass or anything. It should fit nicely in a mix. However beware: some of the filters vary wildly across their parameter range and you can blow a speaker. Many of the especially peaky filters have a sweet spot where just the right combination of settings causes an explosion. It’s fun in practice but can be a pain if you’re trying to do some musical modulation.
To me, the main question about the Morpheus today is: does it do something I want that nothing else can do? Surprisingly, no one in this era of cheap digital processing power seems to have really copied the Morpheus’s raw filter capabilities. The closest hardware is E’mu’s Proteus-2000 synth and Ultra sampler families, which both include a limited set of Z-plane filters and limited or no morphing (the manuals are unclear, and I haven’t had a chance to demo either recently). E-mu’s X3 or other software seems to have advanced filters, but it’s all seemingly obsolete and hard to buy (or authorize). The only other option is really to assemble your own morphing filters using modular or virtual modular synths. While it’s not too hard to build a nice morphing filter in something like MAX, copying the full morphing topology is a pretty big project; I intend to give it a try but don’t know if I’ll succeed (or, if I do, whether it will sound good or be very usable). Granted, just because nothing reproduces the full Z-plane morphing filters of the Morpheus doesn’t mean that you can’t get pretty close; I suspect that the Proteus-2000 (or other modern synths with lots and lots of filter options) can get most of the way there for most people. But still, the Morpheus (and its sibling the Ultraproteus) is apparently still unique.
For me, even having the Morpheus for a short time, I got frustrated with my inability to modulate it the way I wanted. If I owned one, I can imagine it occasionally showing up for some interesting filter effect, but not being something I would turn to most of the time, which doesn’t seem to make it worth the prices they usually command. The concept though is inspiring — aside from wanting to revisit the Proteus-2000 or Ultra, I’ve been working on some Morpheus-inspired filter ideas in MAX and hope to eventually create my own Morpheus homage.
With 197 different filter types and several dimensions of variation, just dialing up a good sound can be daunting on the Morpheus. One of the first things I did when I got my hands on one was set up knobs mapped to morph, frequency tracking, and transform2 and work my way through all the filters, noting down the ones that I liked and thought I might use. Here they are, organized loosely by type. This is, obviously, totally subjective.
