It was the stuff of legends – a richly capable polysynth from the mind of Dave Smith, with only 800 units making it into the world. But now as makers chase the same clones on repeat, the T8 finds its way onto another innovative and overlooked flagship, today’s Sequential Prophet X and XL.

I wouldn’t normally write about sample packs, let alone add-ons for particular hardware. But Sequential’s Prophet X and XL are already uniquely sophisticated instruments – monster polysynths combining dozens of gigs of “deep sampling” sample content with analog synthesis, in a hybrid giant. The sample shop that assembled the sounds for that Prophet, 8dio, have gone back to painstakingly recreate the T8 as an add-on to the new Prophets.

The resulting combo could be the best modern Prophet available at the moment. The T8 had the soul of a Prophet-5 architecture, but was decades head of its time by unveiling polyphonic aftertouch keys (take that, MPE). Those T8 sounds, sampled here in detail, are a natural pairing with the Prophet X’s stereo analog filters, deep modulation, dual digital effects, and polyphonic step sequencer, plus its own superb keyboard.

8dio worked with Dave’s own, immaculately maintained T8 for the samples.

8dio has also made add-ons featuring the ARP 2600 and OBX.

The pack is just US$48, so while picking up a Prophet X or XL is hardly cheap, what you do get here for your investment is a serious alternative to assembling a bunch of software plug-ins for this sort of sound design depth.

The bad news here is really about a limitation of the new Prophets – Sequential doesn’t do polyphonic aftertouch or MPE on their new keyboards (though there is polyphonic glide). I’m rather hopeful that the reemergence of the T8 prods Dave and team to consider doing that, following Bay Area leaders like Roger Linn who helped drive the adoption of polyphonic expression in MIDI. These sounds deserve some control from more than one of your fingers at a time. (You get just mono aftertouch on the Prophet X/XL.)

But whether you’re a Sequential owner or not, it’s worth spending some time revisiting the T8 in all its 1983 glory – this is an early 80s synth that seems more like something you’d get now.

You absolutely should check out this copious review / history from greatsynthesizers.com for everything you could hope to want to know about this axe:

There’s a lot of stuff in that keyboard – optical sensing, release velocity as well as polyphonic aftertouch.
