All modules come in a 'triple' panel format that is 5U in height and 325 mm wide. Rob's philosophy and concept of a modular system is that each 'function' has its own inputs and outputs and should be patched up with cables, and not specifically that each function should be a separate physical entity. So, a triple panel is more like a 'section', offering specific musical functionality by grouping together a sensible collection of functions.<ref name=":2">Direct correspondence with Rob via email. </ref>

A frame holds the modules in a way that it becomes one solid block. A frame can easily be mounted in a DIY cabinet made of just four shelves, it is fixed in a cabinet with a set of woodscrews from within the frame into the side shelves. Frames can be made up to three triples in width (976 mm wide) and basically any number of rows in height (225 mm per row). The most popular frame is two rows of two triples and measures 651 mm in width and 451 mm in height. The plywood flightcases have their power entry either on the left side or on the right side of the case. This should be specified when ordering. The lightweight flightcase has its power entry on the front and for this it needs the TriLFO-Matrix6x4-Nodeproc-MIDI-IECinlet triple or the Rungler-Matrix6x4-Nodeproc-MIDI-IECinlet triple. It lacks the +/-15V MiniXLR power outlet that is available on the other MIDI triples. The MiniXLR might be used for future expansions, to power e.g. a Blippoobox or for powering DIY projects. It should be considered just a convenience if ever needed and not a necessity.<ref name=":2" />

The power supply used is a Meanwell RD-3513 set to +/-15V. It accepts an input voltage between 100VAC to 240VAC, meaning it can be plugged into a wall anywhere in the world. One PSU can safely supply current to four triples, for a bigger system a second PSU is recommended. The power distribution board uses MOTM-style connectors and modules with the +/-15V MOTM header can be readily connected and used. However MOTM modules use another 44 mm based grid than the 107 mm MU grid used in the triples, so they would leave a small gap. However and more important: the standard MOTM mounting holes are not compatible with the metric frame profiles, so they can not easily be fixed in our frame. In practise this means that in a user built cabinet with a section for a frame and a section for MOTM modules the MOTM modules can be powered from the Meanwell PSU + power distro board, but it is physically not feasable to mount a MOTM module in a frame without drilling extra mounting holes in the MOTM module front panel.<ref name=":2" />

Systems were built in a number of different configurations and cases depending on the customers request. A full four triple-module system in a plywood flight case weights about 23 kilograms, the lightweight flightcase reduces this to 16 kilograms.<ref name=":2" />

As everything is hand built there can be minor cosmetic issues like dustmarks anodized into a frontpanel or some lettering slightly out of focus, basically the usual things that are simply unavoidable with handwork. All electronics however are thoroughly tested and burnt in for several days before a system leaves the workshop. Only high quality precision components are used for the electronics and all pots are of the 'conductive plastic' type that will never develop crackles in the sound and easily last ten times as long as the more common carbon pots. Everything is designed to last a musicians lifetime and first time owners have unlimited warranty on parts and repairs.<ref name=":2" />

Within a 'module' in a triple there are several internal normalizations on the input and output jacks, but there are very little 'module to module' normalizations in triple panels and no 'triple to triple' normalizations.<ref name=":2" />
