MOTM

Very cool.  Two MOTM modules shipping within a month of each other.  This
will be a good fall.  My wife is now ready for one of the 1U easier
modules.  I have (lied and) told her the 410 and 320 would be too difficult
for her (so I can have them all to myself).

RATE or SPEED either one seem appropriate for LFOs to me.
