9.1.2 Sequencer and Arpeggio synchronization
How to synchronize the Sequencer and the Arpeggio each other or within your music software
application could be difficult when you don't understand some of the following rules.
Synchronization of the two modules :
The Arpeggio and the Sequencer are sharing the same clock system only when they are MIDI synced
or when the sequencer is trigged by the keyboard. Otherwise, their clocks are independent.
When the MIDI sync switch is ON, the sequencer and the arpeggio are sharing the same clock
system, and so, output their content at the same moment. But this doesn't mean they are totally
synced: When a note is entered on the keyboard, the arpeggio will output it only at the next clock
step.
So if the sequencer is running, you have to enter the note exactly when the new step is output,
otherwise you will feel that they aren't synced.
To be sure the two modules are totally synced you need to switch ON the MIDI sync control and to
switch ON the sequencer “trigger” control. In that way the arpeggio will output the note at the same
time you enter it on the keyboard while the sequencer restart its clock and reset its sequence.
The two modules are totally synced.
Synchronization of two instances:
To synchronize two instances of the PolyKB within your music software application, you need to
switch ON the MIDI sync control on the both instances, but also the switch ON the sequencer”
trigger” on the both instance too, even if the arpeggio instance doesn't use the sequencer.
9.1.3 How to modify a preset to make it V2 compatible
The differences between version 1 and version 2 of the PolyKB stand in the way the
modulation are applied especially for the VCA. For instance, it is now possible to mute a VCO with
an envelope, which was not the case previously.
The PolyMYX (see below, Polyphonic Modulation YX pad) has also been changed; the
amount can be set positively or negatively, which was not the case previously.
If you want to modify a preset created with a previous version you need to tune the following
parameters :
•
Set the Noise modulation amount to 50%
•
There is a difference in the noise spectrum with the version 2 (when the new modulation
mode is enable). This change remove some bad digital frequencies in the upper high of the
spectrum, but this implies that you have to increase a little the amount when it is the source
of a modulation (for instance when the destination is the filter frequency, change the amount
from 50% to 60-65%)
•
Set the amount of the PolyMYX according to the following rule : replace an amount of x%
by (x%+100)/2
