This is the Pulplogic Lunchbox version of 'Semi Sane 84 V2'. The CESYG DuaLFO was sacrificed because it wouldn't fit, both in height and width.Lunchbox 54 Theremin V3 has two goals in mind:
Voice for a theremin-like controller
Self-generating, evolving drone
This rack is centered around the Morphing Terrarium and the Dreamboat, which both have LFO/VCO capabilities. The Terrarium is the primary sound source, while The Dreamboat is the primary modulator.The nice thing about these modules in a 54hp context is that they have limited CV modulation inputs: the Terrarium has 3, and the Dreamboat, 2. The Optomix has 6: 4 CV and 2 gate, divided amongst its two sections. So, we have 9 CV and 2 get destinations, for a total of 11.Providing modulation support are 3 modules: the AnVilope, Wave Runner, and A-143-9 QLFO. These modules command 7 modulation outputs. Together with the Dreamboat's 5, that amounts to 12 modulation sources. The tile portion of the Lunchbox provides additional modulation capabilities.The input is handled by EO-310 and EO-311 modules, which connect to a ribbon controller for pitch, and an infrared distance sensor for volume. The volume connects to the EO-310 to set the proper response and generate the initial sync gate. Three sensor inputs remain open.Final sound processing is handled by the aformentioned Optomix. It offers damp and pluck parameters to further shape the sound, but these seem more aimed at percussive sounds. We will think more about this.Rounded out the rack is the Erthenvar tiles. You get 9, 6 of which can be powered. One is the obligatory Out. Next, Attenuverters are provided for the Terrarium CV ins, which is recommended. A DC source is provided to modulate the Doepfer LFO, because we want the option to take it really slow. The blank tiles are reserved for these functions:
A dual passive gate-to-trigger converter, since we are usually going to sync our oscillators or pluck the Optomix, rather than gate the envelope.
A home-made expansion module for the Terrarium, modelled after the 1U homeade Eurorack version.
