MOTM

so who's up for a little quiz? :)

i've been reading thomas wells' 'the technique of electronic music' and boy 
do i have some questions. in no particular order:


he talks about exponential vs. linear VCOs: expo. being for audio signals, 
lin. to be used for frequency modulation of other signals (as CVs). are 
there any plans for linear MOTM VCOs?

how would one realize the following envelope: ADS DS DS ... R ?  by 
chaining ADSRs somehow?

inverters: will a future MOTM inverter most likely change a signal's phase 
180 degrees, or might it be adjustable over a range?  and will it do the 
same for CVs?

would someone tell me the (electrical) difference between mixing and 
summing signals?

wells describes formant modulation as modulating the cutoff freq of a 
carrier with the amplitude of a modulating signal.  how does this work in 
real life?? will i be able to send a carrier signal into a motm440 and 
control its cutoff with a modulating signal sent through an envelope follower?

how to 'remove' one side of an AC waveform and be left with only its neg. 
DC component or its positive? (am i using proper terminology?)

i know we've been over this before, but  why is it not possible to control 
the MOTM100's vibrato rate with a pot?

i'm all intrigued with frequency and amplitude modulation now. i look 
forward to having the modules to experiment with sideband suppression and 
all that nonsense......
