The tempo changes in Lydian are relatively simple. An LFO clocks an
Oakley Sample & Hold that is sampling the Pink noise from the MOTM-101.
A new random voltage happens every 5 seconds or so. This is sent to the
FM input on a MOTM-390 LFO that generates the main clock. The Oakley
S&H has a restriction control to correlate each sample with the previous
one, so that in this case the tempo changes are not as drastic as they
would be without the correlation. There is only this one varying tempo,
driven by the main clock. But there are two voices, one of which comes
in at random moments (as determined by a different S&H setup). The
second voice is that little wobbly thing that pans across channels once
in a while. The second voice is gated by an action of the main clock
(using a MOTM-700), so it comes in on tempo. There are more than 30
modules in this patch.
