I've been dropping hints about this project for a while, and although it's not quite ready for release I wanted to get some feedback... these modules are based on the Turing Machine and its expanders (with permission from Tom Whitwell). What started as a straightforward SMD conversion of the originals morphed into something new, with some extra features added, such as:

- Arbitrary sequence lengths from 1-16, with VC
- Bipolar VCA for the sequence output (+/-8V range)
- Improved clock input circuitry to work with a wider range of sources

The 18hp version includes:

- Pulse outputs for each of the 16 bits (+10V): built-in Pulses expander
- Pause switch (skip external clocks to pull sequence backwards in time)
- Clock switch (generate internal clocks to push sequence forward in time)
- Inverted output (also controlled by the VCA)
- Clock output (regenerated clock input)
- VC over the Clear and Write switches (program the shift register externally)

The 12hp version lacks the luxurious extras of the 18hp version, but retains the core functionality including VC over the three knob parameters, and pulse outputs for the first 8 bits.

The 6hp version is a minimal take on the concept, with an assignable CV input (labeled CTRL) that can be routed to one of three parameters (Shift, Bits, or Amp) by holding down the Clear/Write switches for 500 ms. The SEQ output has a range from 0-8V and the GATE output maps to the first bit of the shift register.

Variant is a compact version of the Voltages expander, with VC over both of the outputs and a jumper option for controlling whether the Positive and Negative controls handle attenuation or offset (versus the fixed choice of the original). Variant connects to the "gates" header on Permutation, which can also be used to drive the original Voltages and Vactrol Mix expanders (check the video above for an example of the original Voltages expander being used). Variant is also be compatible with the original Turing Machine.

Looks fantastic! I vote 18hp. W/other versions of the same concept out there, it seems like it would make more sense for a new alternative to differentiate as much as possible w/features vs. economizing on space.

Go big! Love the concept and additions to the original!

The 18HP is the way to go for me. Love the all-in-one panel version you did of the Turing Machine, so it would make sense with this too. The additions are worth the HP. It's peanut butter jelly time!

Any way to add a quantized voltage somewhere?

It's full of stars...

something wonderful

Also +1 for the 18HP.

Well done!

I'd also favor the 18 hp version. Demo is hot! Looking forward to this.

Can they recall saved sequences after power cycle? That's what I wish most of my origianl TS. In any case, looks good. I tend to go for smallish sized modules, but I'd say keep maximum features if possible.

Will there be a DIY version or just pre-built?
tarmoog
One "gates" expander input only or more?
Nielsen
Looks great! I would prefer the smaller version since I won't need the extra features. I like the VCA implemenation. One thing I love about the Turing Machine is his small footprint.

Without an MCU with non-volatile storage that seems unlikely (unless supercap? or battery?) so it might depend just how far it morphed from the original (which didn't have an MCU). Similarly with the quantizer.

make the big one. those black panels are dope. looks great really. i like the layout.

+1 for this! This would be a total game changer for me.
voldemar_p
Give me one please!!!
tFunk
Looks very cool!
+1 for the silver 18HP one.
jwm
i suppose all this will depend on pricing, but for me, i think i'd prefer the 12hp one, since invariably i would have to pair it with a quantizer.
secrethero303
I think I'd prefer the 18hp layout. The ability to control clear and write from CV seems useful.
IstvanM
Another vote for the 18hp. This looks great!
thetaflux
I vote 12hp. a very nice size with still a ton of functionality for those of us with small systems!
Groundloop
Very interested in the full featured 18hp version, in black. thumbs up
windspirit
Could you maybeale the 12 hp version and ass the extra features to another 4hp expander? I know that would make a second expansion port but this way everyone gets what they want wink.
Bambou
I vote for the 18 hp !

Same here.

18hp here as I have exactly that space 'free'...

I feel that the 18HP version makes a lot of sense. Count me in for one!
