My (only) case is a 3U126HP, and yes, it requires a combination of long and short cables (which have distinct colors modeled on the wavelengths of light, red being longest, violet being shortest).
I would not recommend a long case for the next generation of Isms.
I'll ask your forbearance as I noodle about the future.
Thinking about a next-generation Isms, I start with a few requirements:
- It needs to conform to rules for carry-on luggage.
- It needs to have a side- or back-mounted power plug to avoid taking up panel space.
- It needs to include basic utilities (such as those offered in the 1U Isms row)
- It needs two VCOs, a VCF, a mixing module and a function generator (essentially the Mannequins modules featured in the first Isms).
- It needs an interface with external effects (e.g., something along the lines of the discontinued AD ODIO )
- It needs two Ansibles, a Walk and a Teletype.
- It would benefit from a light
- It would benefit from some form of stand
- It would benefit from a MIDI interface
- It would benefit from the ability to close the case in a patched state.
Given that the Mannequins + Monome HP count as proposed above is (10+10+10+8+14 + 6+6+4+18)=86HP,
And given that the Isms v1 utility row is 120HP,
My proposal would be for a 8U60HP case configured 1U+3U+3U+1U,
Monome modules on the bottom row and Mannequins on the top,
which would leave 34HP for additional modules/capabilities.
