MOTM

to paul and everyone on the list :
here are two questions that recently came to mind -
1) on the 120 module - it uses xor gates. i recall a similar electronotes 
module that used and gates.  would it be feasible to have a switched option ? 
 would using different types of logic gates provide different types of sound 
outputs ?
2) would the filter topology used in the 410 lend itself to a switch to 
convert the bp response to a notch response ? this would give possibly give a 
nice phaser type sound and from using phasers in the past that used the more 
standard all pass response, i know it does sound different.
best,
dave v.
