Det har tidigare gått lite rykten kring ngn breakoutbox som utvecklats för användas med 777:an, här är lite mer info från jered på future retro till shawn på analoguehaven.com
"The expansion box is still being developed, so some aspects of it's design may change.
For now this is what we have planned.
A wide range VCO that produces all four common waveshapes, including PWM. This VCO can act as either a VC LFO, or VC oscillator. So it can be used as an audio source or modulation source.
Also planned is a multimode resonant filter with both low and highpass response. A True ADSR type envelope with normal and accent envelope times.
We also hope to include a VCA, and possibly a S+H unit.
The idea is that this box could be used with the Mobius to create a simple monophonic synth, with the 777 to provide more audio and modulation capabilities, and basically give the Revolution all the same posibilities of the 777 and more.
Not sure when exactly this will be released... Hopefully in mid to late 2005.
Thanks,
