emusonacid! legacy

hi!

I have recently bought an e-mu E4X (but not received it yet).

I'm planning to make extensive use of the synthesis capabilities
of the EOS.

There's some sounds that I specially love : the sync sounds
(can be obtained with JP8 or Prophet 5 for instance).

Is it possible to make these sounds with a sampler ?

Of course it would be easy to sample them but I would prefer
using sampler "synthesis".

I think the Korg DSS1 could do something like this maybe.

Any help appreciated!

if you can find good sync samples you can make some presets that you would like. the emu is not a synth and cannot sync osc's (because it doesnt have any!)
to get those sounds you'll have to find sync samples or sample them yourself from another synth...
the kind of sampler synthesis that you're talking about doesnt happen on emus.. roland sh32 for example (which uses pcm sampled sounds) can sync its oscillators.. but its not really a sampler.. so thats sorta "sample synthesis created sync" you'd want an analog or va synth for making your own sync sounds...
emus are great and even though you wont be able to make sync sounds with it, you can find and modify sync samples... im sure you'll have fun either way!

What exactly is a sync sound per se?

Unless I'm mistaken, when the oscillators are sync'ed, the wave of the 2nd oscillator restarts at the beginning no matter what every time the 1st oscillator has completed its cycle, which becomes interesting when the 2nd osc is detuned by say, a 5th. Assigning an ENV in addition to detuning creates the famous sync sound effect.

Oscillator sync, or hard sync, is another commonly available waveshape-altering process. In that process, one oscillator, called the slave, is forced to restart its waveform in sync with another oscillator, called the master. With hard sync, the master oscillator controls the pitch. Changes in the slave oscillator's pitch setting don't change its pitch; rather, they cause its waveform to be truncated at different positions, thus affecting its tone. The mix of the master and slave oscillators in the audio output determines how pronounced the effect is.

OK so I'll have to make samples of sync sounds, that's not a problem.
I'll probabbly use some vstis.
thanks for the help!

You'll have to multisample quite a bit if you want a Envelope-modulated sync sound as the sync effect will be shorter as you play up the keyboard. The Jupiter section of the EIIIx "Vintage" CD has a couple of nice JP8 sync samples.

If you want to sample them from a VSTi, NI's Pro-52/53 makes some wonderful sync sounds. A lot of their presets are sync sounds too.

yeah I played with the pro 53 a bit and I love those sync sounds !
But you know what?
I just read the EOS manual quickly and somehow I still think that maybe
it would be possible to create sync sounds with clever programming.
I could use single cycle waveform samples (square, saw) and with all those modulation sources and modulations, maybe I could get some sample retriggered by another one... I'm surely wrong but I like to dream a bit !

Always worth trying.

the transform multiply function can sometimes give sync-like results, unfortunately it takes ages.

also looping short synth sounds can give sync-like results, especially if you make the loop shorter then one cycle. in theory you should get them moving by assigning a cord to Sloop (never tried it, although it's very nice on the asr-10 if you get the transwave stuff going)


what i do a lot to get more agressive 'waveshaped' sounds is sampling an analog synth with detuned voices through a clipping desk, if you hit it hard enough the beating of the osc's becomes kind of a harmonic moving filter.
the nice thing is that you can use the eq as a 'shaper' for the beating. if your sound lacks sub due distorting just use the peakshelf afterwards. especially nice for dubstep/d'n'b basses.
