Product Description
(This module is included in the System B)
The SD09 can modify incoming MIDI messages channel numbers to achieve some useful tasks. Such as resolving channel conflicts in a hardware studio. Polychaining hardware. Generating MPE MIDI without the need for MPE hardware. And/or quickly controlling multiple hardware with a single hardware controller without the need to change hardware channel settings.
The upper section of the SD09 is a MIDI channel filter. While the lower section specifies the channel number to be “converted” to. When Choice/Range switch is set to Choice, This allows you to specify either 1 or 2 MIDI channels to filter in. For example, if the first channel is set to 2 and the second channel is set to 5. Then only MIDI messages with channels number 2 or 5 will be “filtered in” by the module, any thing else will be filtered out and sent to the drop output port. In Range mode, all channels from 2 to 5 will be filtered in, else is dropped.
Tip: In Range mode, if you want to exclude a range instead of including it, take the output from Drop and send to a second SD09, with AL as input channel, and convert from there.
There are 5 modes for conversion. Map, Increment, Decrement, Voice and Filter. Map mode simply converts the filtered in messages to the chosen output channel. Inc mode will add the number chosen to the filtered in channel. Dec mode will subtract the number chosen from the filtered in channel. Voice mode works in polyphony, it sets the channel number to the same number of the voice that generated that MIDI message. The output channel number display has no use in this mode. In this mode, you have to set the module right click menu to poly (uncheck mono). And set polyphony higher than none.
Voice mode can allow you to poly chain multiple hardware/software when combined with the SD05 and SD06. So that one keypress on the keyboard is sent to say one synth. The next keypress is sent to another synth. And so on. Here is a simple example preset that demonstrates how this is done:

Also, If you have hardware/software that supports RECEIVING MPE MIDI. You can generate MPE messages in SoloRack without using any MPE hardware source. Here is an example preset that demonstrates that:
Download MPE_source preset
In this preset, two of the four channels are being modulated with CC. This preset assumes that channel 1 is the master channel (ie. lower MPE zone). Thats why there is a second SD09 that increments all channel numbers by 1 to avoid using channel 1. Your receiving hardware/software should be setup to heed that. Otherwise, if you intend to use channel 16 as the master channel. Then you can simply remove that second SD09 from the preset. Everything should work fine without it in this case.
Filt mode will disable conversion completely by setting both out and drop channels to a blank (ie. no channel). This will allow the module to work only as a MIDI channel filter.
The 4 channel displays can be changed not only manually but also programmatically by sending specialized CC messages!!. Set the CC20+ switch to enable this feature. Then if you send a CC20 with a value from 1 to 16, the first input channel will change to that value (sending zero will set it to ALL). If you send a CC21 with a value from 1 to 16, the second input channel will change to that value (sending zero will set it to a blank). And so on, CC22 for out channel, and CC23 for the drop channel. Those CC messages have to be sent on channel 16 by default. If you want to change that default, send a CC24 with your desired channel number*.
* If sent values are more than 16, then the values are divided by 16, the remainder of that division is taken as the channel number.
