Schematic:
PC1600/PC1600X
What is the difference between the original PC1600 and the PC1600x?
Expanded SysEx Control
•
Checksum-- Now it is possible to designate a byte as "cs" for checksum calculations.
•
Global Channel Bytes-- Many MIDI products use SysEx messages that include a MIDI channel and/or device ID. This is,
•
of course, handy for differentiating among multiple units of the same type. Normally, changing this byte would require
editing of each fader/button individually. Now, a new byte can be a part of the string that specifies the global MIDI
setting or global device ID. By simply changing the global setting, all messages are changed.
Improved SysEx Transfers-- New MIDI delay parameters to slow down the MIDI stream if you have a unit that "chokes"
•
on the data at full speed.
Expanded Button Facilities
•
Send Fader-- This feature provides an easy way to send specific fader values. When a button is set to "send fader," it must
•
be pressed to enable a fader value to be transmitted. Fader movement is used to select a specific value and the button is
pressed to send it. BTW, continuing to hold the button down will enable the fader to work as usual.
Send Scene-- This new button function allows any scene to be sent from any of the 16 buttons.
•
Fader ID-- With a button programmed to "Off/Fader ID," pressing the button displays the fader name.
•
Remote Control-- All 16 buttons can now be triggered externally via MIDI notes or program change messages. This is
•
particularly handy for control from a footpedal.
Note Capture-- This makes it easy to capture clusters of notes (chords) and assign them to a button.
•
Left Arrow(Mute) Button-- When the left arrow button is pressed, the PC 1600 will not generate any MIDI messages.
•
Preset Initialization-- This new utility feature allows a preset to be returned to an initialized state. This is handy for
•
programming from "scratch" or freeing up more dynamically allocated preset memory.
Enhanced Scene Features
•
Preset Identity-- The scene display now indicates the associated preset number.
•
Scene Initialization-- This new scene function allows an existing scene to be initialized which disassociates it with any
•
preset.
Setup String Additions
•
Scenes-- A scene can now be assigned to each preset. Anytime the preset is recalled, the scene will be transmitted.
•
Flexible Bank Select-- Bank Select editing is now expanded to include MSB or LSB programming.
•
New Factory Presets-- New factory presets present a wide range of applications.
•
The only "Physical" change is a larger "Encoder Wheel"
Notes:
1... PC1600 Front Panel, Sheet 1 of 1, Left edge of page cut off.
W0@CR130, W1@CR131, W2@CR132, W3@CR133, W4@CR134, W5@CR135
Should read: SW0, SW1, SW2, SW3, SW4, SW5
These are the same designators at the bottom of the switch array.
Just in reverse order, they do not connect to themselves.
Resulting in the "Step" formation through the middle of the switch array.
