LFO Generators

The   Kiwi-8P   has   3   independent
LFO generators. These each have
6   waveforms   and   can   be   free
running or sync'd with the master
clock with a divider. Each LFO has
it's   own   sync   divider   with   16
possible   divide   ratios   including
swing options.

LFO 1 & 2 will continue to free run
when a new note is pressed after
all   notes   were   lifted.   LFO   3   will
restart   (sync)   its   wave   to   a   first
note played after all notes lifted.

When LFO's are running as sync'd
they need 2-3 cycles of the clock
to   correctly   measure   the   current
rate   and   generate   a   sync'd   rate.
Until this is measured the LFO will
not run correctly. This can take a
while   with   a   slow   master   clock
and/or long division times.

Each LFO can be Normal or Plus 
mode. Normal will move the base 
above and below the normal 
parameter level and plus mode 
will only move the base level up. 
Each section of the Kiwi-8P that 
uses LFO input can select from 
one of the 3 LFOs and can also 
select whether the LFO is normal 
or inverted.

Envelopes

The Kiwi-8P has three independent
Envelope   Generators.   The
Envelopes   generated   are   also
available   as   Matrix   sources.
Envelopes   1-3   are   the   traditional
ADSR type and closely match the
existing JX-8P envelopes.

Note – Due to technical problems
the   EnvKey   control   is   currently
disabled. We are not sure if this can
be solved or not at this stage.
