ZMC-200 Manual Rev2.0
Your main preset should then be set to “NO CONTROLLER” instead of
“VOLUME 7”, so that only the arpeggiator will be affected by the wheel
and the volume setting of the main sound will remain constant.
Use the EXIT button to get back to the main menu.
NRPN/RPN
NRPN/RPN (NONE, NRPN, RPN)
Many manufacturers of synths allow you to set sound characteristics of
their presets using so called NRPN’s (nonregistered parameter numbers) or
RPN’s (registered parameter numbers). According to MIDI specifications
RPN’s have standardized functions and NRPN’s do not. The functions of
NRPN’s are dependent upon the manufacturer and are found in the
individual user’s manuals. The process for using RPN’s and NRPN’s is
identical as follows:
NRPN-LSB and MSB or RPN-LSB and MSB set system parameters using
Controller #6 (DATA ENTRY MSB) or Controller #38 (DATA ENTRY
LSB) to access them. Here is how you access these settings in your ZETA
SYNTHONY II:
You have extracted from the user’s manual of your synth/sound module
that the manufacturer uses NRPN: MSB=01h and LSB=21h for a filter
function for example. Use the +/- Value buttons to select the setting
“NRPN/RPN:…NRPN” and press the ENTER button. The first line of your
display shows you whether you are editing NRPN’s or RPN’s. The second
line shows you the present value for MSB and LSB. The cursor is in the
MSB field at first. Use the +/- Value buttons to set this value to 01h. With
the +/- Parameter buttons move the cursor to the filed LSB and set the
value here to 21h. You have now set the NRPN so that Controller #6 (or
#38) can be used as a filter controller. As a source for controller #6/#38,
you have the option of using any of the three wheel options. Press the EXIT
button to leave the sub menu.
Note: If you are not an experienced user, it is advised that you steer clear of
using the RPN controllers because pitchbend and even tuning information
can be changed.
Another note for “Insiders”: Normally after using a DATA ENTRY
controller for NRPN or RPN Data, these values are reset to “NULL” (7fh),
so that the DATA ENTRY controller has no more influence.
Your ZETA SYNTHONY II does NOT do this, because this would
drastically increase the amount of MIDI data processed and sent. However,
when you
change a Preset, or when you edit an NRPN/RPN, these controllers ARE
set to NULL.
