This rack is actually three, but they belong together, so to keep track of it all I've built them as one rack here.

The top row is a separate audio skiff, the second row is a modulation skiff, and the bottom two rows is the video rack.

The audio skiff is intended to be used in combination with an SQ-1, FX pedals, and a Muscarin, when it arrives: https://www.indiegogo.com/projects/muscarin-semi-modular-synthesizer/ – it's mainly meant to make bizarre soundscapes, partly based on field recordings and stuff.

The modulation skiff can be used in combination with either or both the audio and video cases. It's intended to make chaotic and unpredictable, but somewhat controllable envelopes. In addition to controlling the synths, I'm also planning to use it for controlling lighting (!). A small PureData patch running on a Raspberry Pi takes CV input from the ES-8, processes it if neccessary (slew etc), translates it to a language that my lighting console speaks – currently OSC – and then it controls parameters such as pan/tilt on moving heads. This also works the other way: DMX/ArtNet/OSC from the lighting console is translated to CV which can influence what the control skiff does, or modulate video synth parameters, so that for instanve video colour and modulation speed matches the colour and movement of the lighting.

Depending on how this works out, I may build the control skiff as a 19" subrack that can be used either as a skiff or be racked in a flightcase together with the console.

Outboard video kit includes a PVM 9045QM, multiple Yuan DAC and ADC scaler/converters, Blackmagic Micro Cinema 4K for rescanning, and Blackmagic Video Assist 4K for monitoring/recording, and a good old BPMC Basic Cable for glitchy goodness. The video rack and outboard kit all currently fits in one rolling ThinkTank case – I'll need to do something smart to make the control skiff fit as well.

Ah, but that display is the whole point! :-) The 1340A is an X-Y display with brightness modulation, similar to the Leader LBO-51, Tek 608 and suchlike. It's not a video waveform monitor for diagnostics, but used for Rutt/Etra-style mangling of video images, like this:

A raster display, be it LCD or CRT, is not able to do this – without a vector-to-raster scan converter, that is, but that's a whole different game. This rack is intended specifically for vector image manipulation, all the raster stuff happens elsewhere. I think I already have enough LCD and CRT monitors for that – including an 8" PVM CRT which I haul to gigs. Can't do that tasty composite glitching on an LCD ;-)

Rescan cameras are Blackmagic Micro Studio Camera 4K for the final output (off the 8" CRT) and a small Pelco surveillance camera for the HP vector display. May replace the latter with something that can be genlocked.

Notes to self regarding this experimental rack:
- Case to be used: 8U 10,5 half-rack cabinet, i.e.: http://www.allmetalparts.co.uk/690-8u-105-half-rack-cabinet-435mm-deep-with-handles-5055726206217.html
- LEFT side represents front, RIGHT side represents back. Effective Eurorack HP yield is approximate

The idea is to make an entirely self-contained rescan setup to complement the direct video synth. The Cadet modules represent the basic functionality of a Rutt-Etra scan processor. Certain of them, i.e. Ramps, may be built as 1U tiles to make space for more fun Eurorack modules, i.e. oscillators, modulation or Castle-series modules. The currently shown 1U tiles are not necessarily the ones that will be used.

The 1340A has 9.5 rack mounting ears, but I intend to use a wider rack and simply mount it on a rack shelf to make it feasible to switch to other displays in the future.

The BOTTOM FRONT 1U row will contain mounting hardware (16mm stud) for the rescanning camera and connectors for video and power.

The REAR of the rack includes a TBC2 that will be used both for video input to the scan processor, and for synchronising the rescan camera feed and converting it to LZX 1V video for further processing. (I may try to find a cheaper solution as colour video is not really needed here)

Other available space on the back will be used for a drawer for storing the rescan camera and related cables, as well as power input (PowerCon) and video IO.
