New Manufacturer & Module: Rabid Elephant 'Sololoquy'

Post by PM33AUD »

Image

The first module we'd like to release is called Sololoquy. It's a 10HP programmable clickless VC sequential switch with a handful of unique features. It has 4 main inputs and 2 outputs as well as a CV and CLK input. It can be programmed to work as a mixer or exclusive solo'er/muter. The path is DC-coupled with extremely low offset error & drift. The audio performance is high fidelity. The buttons are high-life (1M cycles) illuminated tact pushbuttons with fast response. They can be played quite nicely.

Sololoquy inputs can be gated by an incoming CLK signal, which is passed by the CLK button. Inputs can also be selected or sequenced using the CV input or with a CLK signal edge.

Buttons action and polarity is programmed by holding the corresponding toggle down and pressing the button you wish to program.

All alternate functions are accessed by holding both toggle switches down and selecting the corresponding button (alt. functions indicated by the graphics). Alternate functions are:

Button 1: switch between Mix and Solo modes
Button 2: enable/disable CV input
Button 3: enable/disable sync
Button 4: enable/disable MIDI sync
CLK button: enable/disable CLK edge sequencing.

Here's a demo vid of the prototype:

Additional features:

MIDI control, sync-ability across multiple Sololoquys, sequence start, stop, sequence pattern programming, auto calibration of the CV input so it can work with many different voltage sources, auto save.

Release Date: In the next few months

A little about us: Our duo consists of an electrical and software engineer, though we both wear many different embroidered bathrobes throughout the design process. We are rabidly dedicated to the reliability, performance, and ergonomics of the stuff we design and build.

That is very neat. A tidy and playable design and a great new take on an old concept. Price is good too. Count me as being interested in getting one for sure. :yay:

Very cool! Can you sequence with the clock input, like moving to the "next" input via a clock pulse?

Nifty, nifty.

I think you're in South Jersey, so if you need an extra beta tester hit me up! :hihi:

But really this is cool. I need a switch, and something that offers more that the A-151 is right up my alley.

Is that 8hp?

We're based out of S. Jersey. I'll keep you in mind if we need some testers.

The module is 10HP. It was originally 8HP but it was too cramped and we didn't want to sacrifice playability. Ergonomics for us is a big deal.

Yes! Thanks for the heads-up... somehow that feature slipped through the cracks.

We are grateful for all of the comments. All warm n fuzzy inside. :oops:

Whoa. This looks fantastic! Does the fact that this has midi capabilities make integrating with a macro machines storage strip any easier? I have no idea if the strip relies on midi at all, but it would be awesome if we could sequence switch configurations. Either way, looking forward to this one :sb:

I do not think the storage strip works with MIDI. It looks like it 'saves' presets (the saved data is in the destination module) via encoded control messages on the CV bus. Our module doesn't have this capability although it's probably not too big of a deal to add - we'd have to see what EEPROM and prog memory we have left over before we'd consider this. We figured MIDI was pretty darn standardized and offers a great deal of flexibility. Sequencing combined switch configurations in mix mode is appealing.

I've also added the module to ModularGrid and put up the current iteration of the panel design since it's a little hard to see in the video.

I think I would buy this when it comes out, I was thinking today about how much I could use a sequential switch and then I was like, "oh yeah, that elephant modules seemed pretty rad." Any expected date/ price?

EDIT: doh! I dont like to read :omg:

Interested, but please keep the demo's coming. Then I will probably go from 'interested' to 'must have' :nana:

We'll have quality demos coming (this one was shot with a phone :deadbanana:) and some more pics.

This module is not bidirectional. We were able to get better fidelity with the current design. Sorry!

Figured an update is in order here since it's been awhile and we've been very busy in the meantime.

Firstly, we're still waiting the release on the new op amp we plan to use for this and several other modules to get the precision/fidelity we are after. TI said August but it still isn't out so I'll have to get another update.

We have a graphics designer who is coming up with a proper theme for both the panels and Rabid Elephant as a whole based on our ideals and personal preferences/styles... it's going very well; it is a healthy and productive dynamic so far.

We've made some tweaks to the device functionality in regards to sequencing which should prove handy.

I've got the first proto boards for the MIDI expander/isolator module in so MIDI testing can (finally!) be completed.

The module was also redesigned to accommodate either regular eurorack or what I am calling 'Eurorack B' which is an improved standard featuring Bantam/TT jacks, balanced IO, a better power connector, proper grounding, and a bunch of other changes. It is still compatible (for the most part) with regular euro but an option for those who want to start traveling towards the light :deadbanana: Folks would choose one or the other configuration and that's how it'd be sold.

Whoa there, sounds like this would justify a new thread in itself!

(Also: if an upgraded Eurorack standard ever gains traction, I'd really be hoping for banana jacks instead of TT. If I'm going to pay upwards of $5 per patch cable, they'd better be stackcable.)

the good thing about standards is there's so many of them.

Will the 'Eurorack B' power cable be KK type? Both Hinton, Elby and MOTM busboards already have provision for KK headers so it might be a good idea to follow suit.

It is a Molex latching and polarised part. Same pitch as the KKs and the MTA156s but different housing and header. The one's I'm using are slightly better because the KK and MTAs stick up too high and despite (sort-of) being polarised, they can still make contact if plugged in backwards. They have same contact and cable resistances as the MTA/KK stuff (which is MUCH better than any ribbon - even discretely wired ribbons with 24ga. wire). I figured if I were doing this, I'd make it more legit.

But no worries, this connector is only on the module end. The other end I can terminate with whatever folks need... MTAs/KK, 0.1" ribbon, ring/spade terminals, etc...

And RE: more standards... well, we're both practising engineers and this format has huge gaping holes when it comes to the engineering dept. The modules I'm making all stem from my and my partner's needs in our own personal rigs... and we are extremely demanding. We are sick of replacing pots and encoders and crappy jacks/cables and dealing with ground noise and loops... So we want another standard at least for ourselves and for whoever else wants the same. Regardless, it's all backwards compatible.

Hinton does something similar in regards to 'standards' for some of the same reasons. I believe his saying is that his modules are not really euro, but compatible with euro. I like this approach. I've just named a new standard is all and have begun documenting it, with much greater detail and guidance. This should help more DIY folks build better modules without having to go through all the background and testing with expensive instrumentation to discover why things are done the way they are.

And RE: the bananas... we'll maybe. But all the work I've spent making for proper shielding and chassis grounds would go out the window, even worse so than a typical 2 conductor shielded unbalanced cable. This only gets noticeable for certain rigs which is why folks still use them (that and the very nice stackability). But if I can pop em on without too much trouble, it can be done to the base version of the module. I've made the jackboards all swappable - so if I find a suitable banana and lots of folks like the banana, I'd make a banana jackboard. I have no problem accommodating custom requests within reason.

Another little update here since I think some things got deleted during the site attack deal...

We are just about wrapping this up and are ramping up for production on this guy.

In the meantime, we've been working hard with Hannes Pasqualini on our visual identity and aesthetic. Hannes has been excellent to work with and we've been honoured. You can see the new panel in the original post.

We also have a MIDI Expansion module that's being wrapped up. This module will allow addition of MIDI to any relevant Rabid Elephant module. It sends MIDI to up to 3 modules 'behind the scenes' using microUSB cables. There are also 2 hardware MIDI Thrus on the front panel.

Yes, I have someone doing us up a proper website (hopefully that is up soon!) which will have a method to buy direct. We will look into distributors once we have an idea of how many of these things will sell. Probably once we have a couple other modules going.

Thanks! (this isn't deleted right?)
