Starting a new topic for this module... Looks very tempting! Especially after watching the YouTube vids (in first link below). Gotta love the Cylon on the faceplate too. thumbs up Anyone else thinking about getting this? Pre-orders are being taken now and it ships this Friday 3/10. Available assembled or as DIY kit.

Interested in this myself...even if it's 50% because it has a Cylon on the front panel

Btw, be sure to check out the many fun videos featuring the Roboto module at Synthrotek's Instagram page:

I especially dig this one with percussion from the Pocket Operator PO-12:

Also this one mangling Queen's "We are the Champions" is entertaining and disturbing:

I preordered and I'm super excited for it to arrive. hyper

There's definitely an aspect of novelty - that darn cylon LED lured me in - but at the very least, you're getting a unique voltage controlled bit crusher/reducer since you have control over the clock rate of the IC. Worth the price of admission for me right there.

Looking forward to just running noise into it and generating interesting percussion by sequencing the CV inputs. The possibility for tons of variation by running a basic drum machine pattern into it, like the PO-12, and using random CV in. (I picked up their RND and ADSR as well.)

Also want to just make a phone recording reciting 'creepy numbers' and create my own number stations by running it into Roboto. lol

I just ordered one! Excited for this!

i'm on the fence. Trying to confirm with my current rig that it won't be redundant first.
circuitburst
Yeah, I'm on the fence right now too. There is definitely a novelty aspect to it, but that is part of the fun and charm of this module. I'm imagining this module will add some excellent percussive elements with careful use of the Robot and Vibrato gate inputs. Of course, the possibilities of altering voice and audio rate waveforms adds a lot to the party too. w00t It would also be really interesting to see a patch where the Roboto is used to modify CV instead of audio!

Pre-ordered one kit... Looking forward to heating up the iron!!

lol me too!

I usually overlook module manufactures who use those micro pots on the front panel. but I might have to break that rule for this one.

In other words, think I might be down for the "kitch N glitch" vibe

I tend to agree with you on a decent interface being a must... also not exceptionally keen on PCB panels. Blame the masses who want to have entire full functionality synthesizers in a cost-effective, skiff friendly, low HP modules. After Maths and Clouds there is only 46HP and very little money left for everything else. The manufacturers are forced to find a balance between different market niches.

There is of course noting stopping you from build a kit with larger knobs and a custom panel.

My hesitation to pre-order is largely wanting to be darn sure that I'm adding something to my modular that I can't do already or that i'll use it enough to not tie up existing modules in a permanent patch.

The chip (HT8950) that this is driven off of is here:
https://www.sparkfun.com/datasheets/Components/General/8950v110.pdf
It's more a A/D converter than an actual vocoder. The sheet also goes into how the vibrato works.

I think to replicate this with other modules you'd need:
- External In
- a downsampler or bit crusher
- a VC pitchshifter
- an LFO (to control the pitchshifting)
- mixer (for wet/dry mix)

Kit on the way!

I kinda only want to buy this for the blinky robot. Please don't judge.

Buy the panel and put the Razmasynth super warp generator circuit behind it?

Or maybe somebody makes a series of these robot modules and once I fill a 9u it turns into Voltron!

I'm trying to source the parts myself. This looks like the pots, but I'm not 100% http://www.taydaelectronics.com/100k-ohm-linear-taper-potentiometer-ro und-knurled-plastic-shaft-pcb-9mm.html

I always find myself second-guessing pot selection without a part number...

I was at Synthrotek on Saturday picking up a RND kit. I knew I would eventually get the Roboto but figured I would wait awhile before getting the kit since I have other modules I need to finish building. From there I went to Sync02 which was our Portland Synthesizer Festival. Synthrotek had a little setup there too and was demoing the Roboto. Of course with all the other demos going on it was a bit hard to really hear it but it was still pretty cool.

Synthrotek happen to have a Promo code printed on little labels they were giving out for 10% off everything for the weekend. By the time I got home I decided to go ahead and order one. It was free shipping so I don't have to run back down to the Synthrotek store to pick it up. Not that that would have stopped me anyway.

On a side note, Rober Linn was there showing his LinnStruments. Those are pretty cool. If I was more of a musician I would probably at least get the 128 Pad one.

That's a rad idea! Especially with adjusting the dry/wet mix. Wouldn't the input need to be DC-coupled though? I'm not sure that it is?

I think I'll make a video of interesting techniques when mine arrives, and I'll give this a go for sure. Any other requests?

Good question about the DC-coupling. I'm not sure about that. Regardless, it would still be fun to experiment with CV to the In jack.

Thanks for offering to make a video. Looking forward to it! Here's a couple other requests...
1. Ambient soundscapes using Roboto and reverb and/or delay. Synthrotek had one example on Instagram here:
https://www.instagram.com/p/BRR51Etg6Bw/
but I'd like to see/hear some more.
2. Create percussion using Roboto and noise or other basic waveform as input.

I'd be more interested in this module if it wasn't so cheesy sci-fi looking. I do see the potential in the audio effect with its cv modulation etc. It reminds me of the Sonic Charge Bitspeek VST effect.

Also, I would like to think that Synthrotek got permission to use the Battlestar Galactica (1978) Cylon image. Someone (ABC?) owns the likeness represented in that image on the faceplate.

Very special guest star appears at around the 8:00 mark. Looks vaguely familiar. Very funny. Got to give this a try!

Question for those who have built or ordered this
I was thinking about getting the pcb and panel. On the BOM, it lists an optocoupler, but without a part or Mouser number. On the visual BOM, they show a big chunky looking thing with four leads. Mouser optocouplers look like ICs. hmmm..... Any idea what that part is? Thanks!

thumbs up

it is a vactrol (the thing that makes modules cool), and is not available from mouser. Best is to order it along with the pcb/panel from synthrotek (they sell it).

Unfortunately, they do not specify the exact properties, it is probably some cheap clone: http://store.synthrotek.com/Vactrol

Ahhh.... Thanks! Could not find the parts list on the Synthrotek site before. It is under "extras" (derp! d'oh! )

Much appreciated! Time to build a robot. w00t

I'm about 80% done with the build, and should finish it tonight. It's pretty straightforward, though I do hate vertical resistors.
