I've seen the CV outs mentioned before but I haven't seen it made coear what exactly they can do. Can it output sequences or work as a primitive midi-cv or what?

Yeah, you can assign it to anything in the modulation matrix.

The list:

lfo1, lfo2: LFO output (centered).
stpseq: Step sequencer output.
stpsq1: Step sequencer’s little brother 1: it cycles on the first 8 steps of the sequence.
stpsq2: Step sequencer’s little brother 2: it cycles on the last 8 steps of the sequence.
arp: Rhythmic gate signal, which outputs a high value when the arpeggiator or sequencer contains a note at the current step, or 0 when there is no note.
mwheel: Modulation wheel value read from the MIDI input.
afttch: Aftertouch value read from the MIDI input.
bender: Pitch-bend controller value read from the MIDI input (centered).
offset: A boring constant value. This is useful if you want to output a fixed value to one of the CV outs.
cv1, cv2, cv3, cv4: Control voltages read from the CV input pins. By default, the input pins are floating, so it’s likely that these modulation sources will sound just like noise.
cc A, cc B, cc C, cc D: Value of the Control Change 16, 17, 18 and 19.
noise: Another noise generator! Mapped to the VCA, makes for some super snares!
env1, env2: Envelopes.
velo: Note velocity.
random: A random value updated every time a new note is played.
note: Pitch of the currently played note (centered).
gate: Keyboard gate signal, null when no key is currently pressed.
audio: Digital audio signal produced by the mixer. Please note that since the modulation matrix is recomputed at 976Hz, some serious aliasing is happening here. You’re not going to do FM with this thing, most of the time it sounds like crap, but it’s something fun to experiment with!
op. 1: Operator 1.
op. 2: Operator 2.

"operators" allow you to combine 2 mod. sources with a mathematical operator.

It's great. And I managed to fit 6 1/8" jacks & protection diodes in the standard plexi enclosure. Just.

Regarding using it as a MIDI-CV with 1v/oct note out, if that's what you are curious about - you'd have to shift it with an operator connected to an offset, and then it would still be linear, 0-5v. Gate output would be straightforward, but you'd need an exponential convertor if you wanted to say have oscillators track its pitch properly.

Great, that was very detailed and gives me a lot of ideas. I guess I'll still need a midi-cv converter, but it looks like my 2012 performance rig is really coming together (Machinedrum UW, Shruthi-1, modular). I'm excited about how well it seems everthing is going to interface!

there is plenty to search for about these cv inputs aka "hack me" inputs @ http://www.mutable-instruments/forum Kenny McCormick

So, I'm finally working my way around this thing. Got this running at the exact same time as I got a Machinedrum and an Oberheim Matrix-6 so I've been up to my eyeballs in menus and submenus and user manuals. Is there a way to share patches with the Shruthi-1? Anyone have any that they would like to share? I could use some ideas. I actually really hate working backwards from the presets -- I wish there was a way to wipe them all.

Shhhhhsh! Stop talking about the good stuff. My kit is still sat in the drawer waiting to be built but I just don't have the time right now.

Really looking forward to building it though applause

well, i finally finished the XT kit in about 2 months as it wasn't the easiest thing to build (had a short on the control board, a lot of trouble shooting). i ended up putting three filters in the box, an SMR-4, IR3109 and CEM3379. as expected, both the roland and CEM filters sound pretty good applause

just a word of caution though, you can't use the SVF board with the XT controller as the SVF needs the digital expansion port (i'm not really sure what that means seriously, i just don't get it

but it doesn't work - i found out the hard way)

the extra knobs make a world of difference, one of the main reasons why i don't use my Mopho as much.

here's some pics. white davies clones, black/white display, and orange/red LEDs. i'll swap out the black buttons with white ones soon, although i can't seem to find a white rubber knob anywhere.

You can use the SVF in tandem with the programmer provided you have mechanical switches hooked up where the switch ICs would be on the SVF board so you can control the modes manually. There are markings on the PC board to help you do this.

The new Shruthi-1 4-Pole Mission Edition looks a bit tasty:
http://createdigitalmusic.com/2012/04/open-shruthi-1-synth-evolves-dee p-sound-capabilities-new-4-pole-filter-ice-white-case/

I see they've stopped providing some of the more commonly available parts in the kit (there's now a saved shopping basket at Mouser or Reichelt for those), but they are supplying that rather lovely plexiglass case. I'm not familiar with the filter but it certainly seems versatile. Think this is going to be my first synth build once the kits are available.

Mission. Sold out. Midipal. Sold out. Sidekick. Sold out. Got a CEM3379
Shruthi thank goodness. Kits are well
done. This co. needs to get a handle on
stocking kits cuz almost everytime I go there it's sold out. Ya gotta watch the forum like a crack addict to get in on most
things. The other drag is the dollar to Euro
exchange but that's an old hurdle. Otherwise roll your own wavetables is
great and the x/or mod possibilities are
endless... almost. ;)
