[sdiy] UK meet up, intro, and a wavetable module plan

[Travis Thatcher]

I think its a cool idea - I've actually been working on a wavetable
module design myself.  I'd recommend prototyping in soming like
Max/MSP to figure out interface etc. Its really helped me out a lot.
Originally I wanted something with sliders, so you could 'draw' out
the waveform, but that would make for some huge panels.  I'm really
interested in morphing various wave forms with cv and coming up with
good schemes to do so.  I hope to have a prototype done in a month or
two.

I'm uncertain whether each should have its own DAC or whether digital outputs should be available to a generic digital function module providing AND, OR, XOR, MAX, and so on. Thoughts? There's no analogue in this because I like the filters etc. in the Fenix; maybe later in life I'll make it more stand-alone.
