Appearance and function match the final product, but is made with different manufacturing methods.

Looks like the final product, but is not functional.

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

INFINITE MULTIPLE

TUNNELS is a new type of Eurorack utility module that allows you to duplicate and route signals across your modular synthesizer. We call it the “Infinite Multiple,” but you could also describe it as an “Inter-Panel Buffered Multiple,” or perhaps a “Mult Bus.”

TUNNELS is comprised of two distinct modules : TUNNEL IN and TUNNEL OUT. The TUNNEL IN module by itself is a buffered multiple, duplicating an input signal to create multiple outputs. The TUNNEL OUT module expands the TUNNEL IN module to add additional outputs at another location in your synthesizer. TUNNEL OUT modules can be chained together infinitely to create massive buffered multiple banks or send common signals like clocks and 1v/oct signals to strategic locations in your synth.

The TUNNEL IN module has three inputs, each routed to a pair of outputs. When disconnected, the inputs are normalled to the previous input, allowing for a variety of configurations. With the first input connected it is a 1 in : 6 out multiple. Using the first two inputs makes a 1 in : 2 out multiple and a 1 in : 4 out multiple. With all three inputs connected, it acts as three 1 in : 2 out multiples.

The TUNNEL OUT module receives the three channels from TUNNEL IN via a TUNNEL LINK cable, adding three additional buffered outputs per channel. With one input connected, for example, you would now have a 1 in : 15 out multiple. Add additional TUNNEL OUT modules to expand your TUNNELS system however you see fit.

Because TUNNELS is a buffered (non-passive or powered) multiple, critical signals like 1 volt per octave control voltages are able to maintain their integrity regardless of the size of the TUNNELS system.

TUNNELS is engineered with live-patching in mind. Normalled connections between inputs are also buffered, preventing the momentary short that can happen with other multiples. This means no dropped clocks or audible glitches in modulation or pitch while working on your patch.

Technical Specs

Both TUNNEL IN and TUNNEL OUT modules are 4 HP and have a depth of 1.5" (38mm) from the backside of the front panel to the top of the Link cable when plugged in.

Max Current Draw :TUNNEL IN +12v 33mA -12v 20mA

+ 5v 0 mA

TUNNEL OUT

+12v 36mA -12v 26mA

+ 5v 0 mA

The TUNNEL LINK cable will initially be available in 5 foot lengths, which should easily accommodate (and then some) most systems.

Why Kickstarter?

Olympia Modular is the first collaboration between Olympia Noise Co. developer Ben Kamen and Buchla Development Engineer Charles Seeholzer. Kickstarter is a great way for us to navigate the production process, gauge interest and raise funds to make it a reality. While we've already invested quite a bit of time and money into the process, this Kickstarter will allow us to minimize our financial risk going forward with this boutique product.

We have already manufactured the first round of panels, developed and tested prototype boards, and received quotes for manufacturing. Now we just need to raise the funds to manufacture the finished product.
