MIDI Program Select

In Page 6 of Global Edit mode, Quad Knob [1] determines the MIDI Program Select
mode (Off, On, Mix Select Channel 1 –16). When this is set to "Off", the S4 Plus will
not respond to incoming MIDI Program Change messages, nor will it transmit
Program Changes.
When set to "On", the S4 Plus will respond to incoming Program Change messages.
Likewise, when a Program or Mix is recalled from the front panel, its respective
program change message will be sent out. However, the S4 Plus will respond
differently to incoming Program Change messages depending on whether Program
Mode or Mix Mode is selected.
In Program Mode, the MIDI [¨] and [Æ] buttons determine on which MIDI channel the
S4 Plus will receive MIDI Program Change messages (as well as other messages,
like notes, controllers, etc.). The Program recalled will be the same number as the
MIDI Program Change message that is received, from whichever bank (Preset or
User) is currently selected. When a Program is recalled from the front panel, the S4
Plus will transmit the equivalent Program Change message on this same MIDI
channel.
In Mix Mode, when MIDI Program select is on, Program Changes received on any of
the 16 MIDI channels will be received by the same numbered MIDI channels in the
current Mix. The Mix itself will not respond to Program Changes.
When set to "Mix Select Channel 1 – 16", the S4 Plus will change Mixes in response
to Program Change messages received on the same MIDI channel as selected by
this parameter, from whichever bank (Preset or User) is currently selected. Program
Change messages received on any other channel (other than the one selected by
this parameter) will change the individual Programs in the Mix on the same channels
the messages are received on.
Note: When General MIDI Mode is enabled (see page 111 ), Channel 10 of the
selected Mix will be used exclusively for drums. If a program change is received on
Channel 10, a new drum kit will be recalled. These drum kits are used exclusively in
General MIDI mode, and adhere to the General MIDI specification.

Receiving and Transmitting Bank Change Message

The S4 Plus will respond to MIDI Bank Select messages. Bank Select messages are
transmitted via MIDI Controller 0. The value of Controller 0 determines which bank
(User, Preset 1–4, Card 1–8) is to be recalled. Example: If a Bank Select (controller 0)
message of 0 is received, it will cause the User Bank to be recalled. If a Bank Select
(message of 1 is received, Preset Bank 1 will be recalled. Additionally, if a Sound Card
is inserted, the Card Banks can be selected using Controller 0 values between 5 and
13. Values higher than 13 are "wrapped around" and will recall the same Banks.
Example: A Controller 0 message with a value of 39 will recall the User Bank.
Note: Bank change messages will be ignored if General MIDI Mode is enabled, so
that only Programs within the General MIDI Bank (Preset 4) can be recalled via MIDI
Program changes.
If the MIDI Program Select parameter is turned "On" and a new Bank is selected
using the BANK [¨] and [Æ] buttons, a Bank Change message (followed by the
appropriate Program Change message) will be transmitted out the MIDI Out
connector.
